Experts Fear Crooks are Cracking Keys Stolen in LastPass Breach

By BrianKrebs

In November 2022, the password manager service LastPass disclosed a breach in which hackers stole password vaults containing both encrypted and plaintext data for more than 25 million users. Since then, a steady trickle of six-figure cryptocurrency heists targeting security-conscious people throughout the tech industry has led some security experts to conclude that crooks likely have succeeded at cracking open some of the stolen LastPass vaults.

Taylor Monahan is lead product manager of MetaMask, a popular software cryptocurrency wallet used to interact with the Ethereum blockchain. Since late December 2022, Monahan and other researchers have identified a highly reliable set of clues that they say connect recent thefts targeting more than 150 people. Collectively, these individuals have been robbed of more than $35 million worth of crypto.

Monahan said virtually all of the victims she has assisted were longtime cryptocurrency investors, and security-minded individuals. Importantly, none appeared to have suffered the sorts of attacks that typically preface a high-dollar crypto heist, such as the compromise of one’s email and/or mobile phone accounts.

“The victim profile remains the most striking thing,” Monahan wrote. “They truly all are reasonably secure. They are also deeply integrated into this ecosystem, [including] employees of reputable crypto orgs, VCs [venture capitalists], people who built DeFi protocols, deploy contracts, run full nodes.”

Monahan has been documenting the crypto thefts via Twitter/X since March 2023, frequently expressing frustration in the search for a common cause among the victims. Then on Aug. 28, Monahan said she’d concluded that the common thread among nearly every victim was that they’d previously used LastPass to store their “seed phrase,” the private key needed to unlock access to their cryptocurrency investments.

Armed with your secret seed phrase, anyone can instantly access all of the cryptocurrency holdings tied to that cryptographic key, and move the funds to anywhere they like.

Which is why the best practice for many cybersecurity enthusiasts has long been to store their seed phrases either in some type of encrypted container — such as a password manager — or else inside an offline, special-purpose hardware encryption device, such as a Trezor or Ledger wallet.

“The seed phrase is literally the money,” said Nick Bax, director of analytics at Unciphered, a cryptocurrency wallet recovery company. “If you have my seed phrase, you can copy and paste that into your wallet, and then you can see all my accounts. And you can transfer my funds.”

Bax said he closely reviewed the massive trove of cryptocurrency theft data that Taylor Monahan and others have collected and linked together.

“It’s one of the broadest and most complex cryptocurrency investigations I’ve ever seen,” Bax said. “I ran my own analysis on top of their data and reached the same conclusion that Taylor reported. The threat actor moved stolen funds from multiple victims to the same blockchain addresses, making it possible to strongly link those victims.”

Bax, Monahan and others interviewed for this story say they’ve identified a unique signature that links the theft of more than $35 million in crypto from more than 150 confirmed victims, with roughly two to five high-dollar heists happening each month since December 2022.

KrebsOnSecurity has reviewed this signature but is not publishing it at the request of Monahan and other researchers, who say doing so could cause the attackers to alter their operations in ways that make their criminal activity more difficult to track.

But the researchers have published findings about the dramatic similarities in the ways that victim funds were stolen and laundered through specific cryptocurrency exchanges. They also learned the attackers frequently grouped together victims by sending their cryptocurrencies to the same destination crypto wallet.

A graphic published by @tayvano_ on Twitter depicting the movement of stolen cryptocurrencies from victims who used LastPass to store their crypto seed phrases.

By identifying points of overlap in these destination addresses, the researchers were then able to track down and interview new victims. For example, the researchers said their methodology identified a recent multi-million dollar crypto heist victim as an employee at Chainalysis, a blockchain analysis firm that works closely with law enforcement agencies to help track down cybercriminals and money launderers.

Chainalysis confirmed that the employee had suffered a high-dollar cryptocurrency heist late last month, but otherwise declined to comment for this story.

Bax said the only obvious commonality between the victims who agreed to be interviewed was that they had stored the seed phrases for their cryptocurrency wallets in LastPass.

“On top of the overlapping indicators of compromise, there are more circumstantial behavioral patterns and tradecraft which are also consistent between different thefts and support the conclusion,” Bax told KrebsOnSecuirty. “I’m confident enough that this is a real problem that I’ve been urging my friends and family who use LastPass to change all of their passwords and migrate any crypto that may have been exposed, despite knowing full well how tedious that is.”

LastPass declined to answer questions about the research highlighted in this story, citing an ongoing law enforcement investigation and pending litigation against the company in response to its 2022 data breach.

“Last year’s incident remains the subject of an ongoing investigation by law enforcement and is also the subject of pending litigation,” LastPass said in a written statement provided to KrebsOnSecurity. “Since last year’s attack on LastPass, we have remained in contact with law enforcement and continue to do so.”

Their statement continues:

“We have shared various technical information, Indicators of Compromise (IOCs), and threat actor tactics, techniques, and procedures (TTPs) with our law enforcement contacts as well as our internal and external threat intelligence and forensic partners in an effort to try and help identify the parties responsible. In the meantime, we encourage any security researchers to share any useful information they believe they may have with our Threat Intelligence team by contacting securitydisclosure@lastpass.com.”

THE LASTPASS BREACH(ES)

On August 25, 2022, LastPass CEO Karim Toubba wrote to users that the company had detected unusual activity in its software development environment, and that the intruders stole some source code and proprietary LastPass technical information. On Sept. 15, 2022, LastPass said an investigation into the August breach determined the attacker did not access any customer data or password vaults.

But on Nov. 30, 2022, LastPass notified customers about another, far more serious security incident that the company said leveraged data stolen in the August breach. LastPass disclosed that criminal hackers had compromised encrypted copies of some password vaults, as well as other personal information.

In February 2023, LastPass disclosed that the intrusion involved a highly complex, targeted attack against a DevOps engineer who was one of only four LastPass employees with access to the corporate vault.

“This was accomplished by targeting the DevOps engineer’s home computer and exploiting a vulnerable third-party media software package, which enabled remote code execution capability and allowed the threat actor to implant keylogger malware,” LastPass officials wrote. “The threat actor was able to capture the employee’s master password as it was entered, after the employee authenticated with MFA, and gain access to the DevOps engineer’s LastPass corporate vault.”

Dan Goodin at Ars Technica reported and then confirmed that the attackers exploited a known vulnerability in a Plex media server that the employee was running on his home network, and succeeded in installing malicious software that stole passwords and other authentication credentials. The vulnerability exploited by the intruders was patched back in 2020, but the employee never updated his Plex software.

As it happens, Plex announced its own data breach one day before LastPass disclosed its initial August intrusion. On August 24, 2022, Plex’s security team urged users to reset their passwords, saying an intruder had accessed customer emails, usernames and encrypted passwords.

OFFLINE ATTACKS

A basic functionality of LastPass is that it will pick and remember lengthy, complex passwords for each of your websites or online services. To automatically populate the appropriate credentials at any website going forward, you simply authenticate to LastPass using your master password.

LastPass has always emphasized that if you lose this master password, that’s too bad because they don’t store it and their encryption is so strong that even they can’t help you recover it.

But experts say all bets are off when cybercrooks can get their hands on the encrypted vault data itself — as opposed to having to interact with LastPass via its website. These so-called “offline” attacks allow the bad guys to conduct unlimited and unfettered “brute force” password cracking attempts against the encrypted data using powerful computers that can each try millions of password guesses per second.

“It does leave things vulnerable to brute force when the vaults are stolen en masse, especially if info about the vault HOLDER is available,” said Nicholas Weaver, a researcher at University of California, Berkeley’s International Computer Science Institute (ICSI) and lecturer at UC Davis. “So you just crunch and crunch and crunch with GPUs, with a priority list of vaults you target.”

How hard would it be for well-resourced criminals to crack the master passwords securing LastPass user vaults? Perhaps the best answer to this question comes from Wladimir Palant, a security researcher and the original developer behind the Adblock Plus browser plugin.

In a December 2022 blog post, Palant explained that the crackability of a LastPass master password depends largely on two things: The complexity of the master password, and the default settings for LastPass users, which appear to have varied quite a bit based on when those users began patronizing the service.

LastPass says that since 2018 it has required a twelve-character minimum for master passwords, which the company said “greatly minimizes the ability for successful brute force password guessing.”

But Palant said while LastPass indeed improved its master password defaults in 2018, it did not force all existing customers who had master passwords of lesser lengths to pick new credentials that would satisfy the 12-character minimum.

“If you are a LastPass customer, chances are that you are completely unaware of this requirement,” Palant wrote. “That’s because LastPass didn’t ask existing customers to change their master password. I had my test account since 2018, and even today I can log in with my eight-character password without any warnings or prompts to change it.”

Palant believes LastPass also failed to upgrade many older, original customers to more secure encryption protections that were offered to newer customers over the years. One important setting in LastPass is the number of “iterations,” or how many times your master password is run through the company’s encryption routines. The more iterations, the longer it takes an offline attacker to crack your master password.

Palant noted last year that for many older LastPass users, the initial default setting for iterations was anywhere from “1” to “500.” By 2013, new LastPass customers were given 5,000 iterations by default. In February 2018, LastPass changed the default to 100,100 iterations. And very recently, it upped that again to 600,000.

Palant said the 2018 change was in response to a security bug report he filed about some users having dangerously low iterations in their LastPass settings.

“Worse yet, for reasons that are beyond me, LastPass didn’t complete this migration,” Palant wrote. “My test account is still at 5,000 iterations, as are the accounts of many other users who checked their LastPass settings. LastPass would know how many users are affected, but they aren’t telling that. In fact, it’s painfully obvious that LastPass never bothered updating users’ security settings. Not when they changed the default from 1 to 500 iterations. Not when they changed it from 500 to 5,000. Only my persistence made them consider it for their latest change. And they still failed implementing it consistently.”

A chart on Palant’s blog post offers an idea of how increasing password iterations dramatically increases the costs and time needed by the attackers to crack someone’s master password. Palant said it would take a single GPU about a year to crack a password of average complexity with 500 iterations, and about 10 years to crack the same password run through 5,000 iterations.

However, these numbers radically come down when a determined adversary also has other large-scale computational assets at their disposal, such as a bitcoin mining operation that can coordinate the password-cracking activity across multiple powerful systems simultaneously.

Weaver said a password or passphrase with average complexity — such as “Correct Horse Battery Staple” is only secure against online attacks, and that its roughly 40 bits of randomness or “entropy” means a graphics card can blow through it in no time.

“An Nvidia 3090 can do roughly 4 million [password guesses] per second with 1000 iterations, but that would go down to 8 thousand per second with 500,000 iterations, which is why iteration count matters so much,” Weaver said. “So a combination of ‘not THAT strong of a password’ and ‘old vault’ and ‘low iteration count’ would make it theoretically crackable but real work, but the work is worth it given the targets.”

Reached by KrebsOnSecurity, Palant said he never received a response from LastPass about why the company apparently failed to migrate some number of customers to more secure account settings.

“I know exactly as much as everyone else,” Palant wrote in reply. “LastPass published some additional information in March. This finally answered the questions about the timeline of their breach – meaning which users are affected. It also made obvious that business customers are very much at risk here, Federated Login Services being highly compromised in this breach (LastPass downplaying as usual of course).”

Palant said upon logging into his LastPass account a few days ago, he found his master password was still set at 5,000 iterations.

INTERVIEW WITH A VICTIM

KrebsOnSecurity interviewed one of the victims tracked down by Monahan, a software engineer and startup founder who recently was robbed of approximately $3.4 million worth of different cryptocurrencies. The victim agreed to tell his story in exchange for anonymity because he is still trying to claw back his losses. We’ll refer to him here as “Connor” (not his real name).

Connor said he began using LastPass roughly a decade ago, and that he also stored the seed phrase for his primary cryptocurrency wallet inside of LastPass. Connor chose to protect his LastPass password vault with an eight character master password that included numbers and symbols (~50 bits of entropy).

“I thought at the time that the bigger risk was losing a piece of paper with my seed phrase on it,” Connor said. “I had it in a bank security deposit box before that, but then I started thinking, ‘Hey, the bank might close or burn down and I could lose my seed phrase.'”

Those seed phrases sat in his LastPass vault for years. Then, early on the morning of Sunday, Aug. 27, 2023, Connor was awoken by a service he’d set up to monitor his cryptocurrency addresses for any unusual activity: Someone was draining funds from his accounts, and fast.

Like other victims interviewed for this story, Connor didn’t suffer the usual indignities that typically presage a cryptocurrency robbery, such as account takeovers of his email inbox or mobile phone number.

Connor said he doesn’t know the number of iterations his master password was given originally, or what it was set at when the LastPass user vault data was stolen last year. But he said he recently logged into his LastPass account and the system forced him to upgrade to the new 600,000 iterations setting.

“Because I set up my LastPass account so early, I’m pretty sure I had whatever weak settings or iterations it originally had,” he said.

Connor said he’s kicking himself because he recently started the process of migrating his cryptocurrency to a new wallet protected by a new seed phrase. But he never finished that migration process. And then he got hacked.

“I’d set up a brand new wallet with new keys,” he said. “I had that ready to go two months ago, but have been procrastinating moving things to the new wallet.”

Connor has been exceedingly lucky in regaining access to some of his stolen millions in cryptocurrency. The Internet is swimming with con artists masquerading as legitimate cryptocurrency recovery experts. To make matters worse, because time is so critical in these crypto heists, many victims turn to the first quasi-believable expert who offers help.

Instead, several friends steered Connor to Flashbots.net, a cryptocurrency recovery firm that employs several custom techniques to help clients claw back stolen funds — particularly those on the Ethereum blockchain.

According to Connor, Flashbots helped rescue approximately $1.5 million worth of the $3.4 million in cryptocurrency value that was suddenly swept out of his account roughly a week ago. Lucky for him, Connor had some of his assets tied up in a type of digital loan that allowed him to borrow against his various cryptocurrency assets.

Without giving away too many details about how they clawed back the funds, here’s a high level summary: When the crooks who stole Connor’s seed phrase sought to extract value from these loans, they were borrowing the maximum amount of credit that he hadn’t already used. But Connor said that left open an avenue for some of that value to be recaptured, basically by repaying the loan in many small, rapid chunks.

WHAT SHOULD LASTPASS USERS DO?

According to MetaMask’s Monahan, users who stored any important passwords with LastPass — particularly those related to cryptocurrency accounts — should change those credentials immediately, and migrate any crypto holdings to new offline hardware wallets.

“Really the ONLY thing you need to read is this,” Monahan pleaded to her 70,000 followers on Twitter/X: “PLEASE DON’T KEEP ALL YOUR ASSETS IN A SINGLE KEY OR SECRET PHRASE FOR YEARS. THE END. Split up your assets. Get a hw [hardware] wallet. Migrate. Now.”

If you also had passwords tied to banking or retirement accounts, or even just important email accounts — now would be a good time to change those credentials as well.

I’ve never been comfortable recommending password managers, because I’ve never seriously used them myself. Something about putting all your eggs in one basket. Heck, I’m so old-fashioned that most of my important passwords are written down and tucked away in safe places.

But I recognize this antiquated approach to password management is not for everyone. Connor says he now uses 1Password, a competing password manager that recently earned the best overall marks from Wired and The New York Times.

1Password says that three things are needed to decrypt your information: The encrypted data itself, your account password, and your Secret Key. Only you know your account password, and your Secret Key is generated locally during setup.

“The two are combined on-device to encrypt your vault data and are never sent to 1Password,” explains a 1Password blog post ‘What If 1Password Gets Hacked?‘ “Only the encrypted vault data lives on our servers, so neither 1Password nor an attacker who somehow manages to guess or steal your account password would be able to access your vaults – or what’s inside them.

Weaver said that Secret Key adds an extra level of randomness to all user master passwords that LastPass didn’t have.

“With LastPass, the idea is the user’s password vault is encrypted with a cryptographic hash (H) of the user’s passphrase,” Weaver said. “The problem is a hash of the user’s passphrase is remarkably weak on older LastPass vaults with master passwords that do not have many iterations. 1Password uses H(random-key||password) to generate the password, and it is why you have the QR code business when adding a new device.”

Weaver said LastPass deserves blame for not having upgraded iteration counts for all users a long time ago, and called the latest forced upgrades “a stunning indictment of the negligence on the part of LastPass.”

“That they never even notified all those with iteration counts of less than 100,000 — who are really vulnerable to brute force even with 8-character random passwords or ‘correct horse battery staple’ type passphrases — is outright negligence,” Weaver said. “I would personally advocate that nobody ever uses LastPass again: Not because they were hacked. Not because they had an architecture (unlike 1Password) that makes such hacking a problem. But because of their consistent refusal to address how they screwed up and take proactive efforts to protect their customers.”

Bax and Monahan both acknowledged that their research alone can probably never conclusively tie dozens of high-dollar crypto heists over the past year to the LastPass breach. But Bax says at this point he doesn’t see any other possible explanation.

“Some might say it’s dangerous to assert a strong connection here, but I’d say it’s dangerous to assert there isn’t one,” he said. “I was arguing with my fiance about this last night. She’s waiting for LastPass to tell her to change everything. Meanwhile, I’m telling her to do it now.”

Key Cybersecurity Tools That Can Mitigate the Cost of a Breach

Why is .US Being Used to Phish So Many of Us?

By BrianKrebs

Domain names ending in “.US” — the top-level domain for the United States — are among the most prevalent in phishing scams, new research shows. This is noteworthy because .US is overseen by the U.S. government, which is frequently the target of phishing domains ending in .US. Also, .US domains are only supposed to be available to U.S. citizens and to those who can demonstrate that they have a physical presence in the United States.

.US is the “country code top-level domain” or ccTLD of the United States. Most countries have their own ccTLDs: .MX for Mexico, for example, or .CA for Canada. But few other major countries in the world have anywhere near as many phishing domains each year as .US.

That’s according to The Interisle Consulting Group, which gathers phishing data from multiple industry sources and publishes an annual report on the latest trends. Interisle’s newest study examined six million phishing reports between May 1, 2022 and April 30, 2023, and found 30,000 .US phishing domains.

.US is overseen by the National Telecommunications and Information Administration (NTIA), an executive branch agency of the U.S. Department of Commerce. However, NTIA currently contracts out the management of the .US domain to GoDaddy, by far the world’s largest domain registrar.

Under NTIA regulations, the administrator of the .US registry must take certain steps to verify that their customers actually reside in the United States, or own organizations based in the U.S. But Interisle found that whatever GoDaddy was doing to manage that vetting process wasn’t working.

“The .US ‘nexus’ requirement theoretically limits registrations to parties with a national connection, but .US had very high numbers of phishing domains,” Interisle wrote. “This indicates a possible problem with the administration or application of the nexus requirements.”

Dean Marks is emeritus executive director for a group called the Coalition for Online Accountability, which has been critical of the NTIA’s stewardship of .US. Marks says virtually all European Union member state ccTLDs that enforce nexus restrictions also have massively lower levels of abuse due to their policies and oversight.

“Even very large ccTLDs, like .de for Germany — which has a far larger market share of domain name registrations than .US — have very low levels of abuse, including phishing and malware,” Marks told KrebsOnSecurity. “In my view, this situation with .US should not be acceptable to the U.S. government overall, nor to the US public.”

Marks said there are very few phishing domains ever registered in other ccTLDs that also restrict registrations to their citizens, such as .HU (Hungary), .NZ (New Zealand), and .FI (Finland), where a connection to the country, a proof of identity, or evidence of incorporation are required.

“Or .LK (Sri Lanka), where the acceptable use policy includes a ‘lock and suspend’ if domains are reported for suspicious activity,” Marks said. “These ccTLDs make a strong case for validating domain registrants in the interest of public safety.”

Sadly, .US has been a cesspool of phishing activity for many years. As far back as 2018, Interisle found .US domains were the worst in the world for spam, botnet (attack infrastructure for DDOS etc.) and illicit or harmful content. Back then, .US was being operated by a different contractor.

In response to questions from KrebsOnSecurity, GoDaddy said all .US registrants must certify that they meet the NTIA’s nexus requirements. But this appears to be little more than an affirmative response that is already pre-selected for all new registrants.

Attempting to register a .US domain through GoDaddy, for example, leads to a U.S. Registration Information page that auto-populates the nexus attestation field with the response, “I am a citizen of the US.” Other options include, “I am a permanent resident of the US,” and “My primary domicile is in the US.” It currently costs just $4.99 to obtain a .US domain through GoDaddy.

GoDaddy said it also conducts a scan of selected registration request information, and conducts “spot checks” on registrant information.

“We conduct regular reviews, per policy, of registration data within the Registry database to determine Nexus compliance with ongoing communications to registrars and registrants,” the company said in a written statement.

GoDaddy says it “is committed to supporting a safer online environment and proactively addressing this issue by assessing it against our own anti-abuse mitigation system.”

“We stand against DNS abuse in any form and maintain multiple systems and protocols to protect all the TLDs we operate,” the statement continued. “We will continue to work with registrars, cybersecurity firms and other stakeholders to make progress with this complex challenge.”

Interisle found significant numbers of .US domains were registered to attack some of the United States’ most prominent companies, including Bank of America, Amazon, AppleAT&T, Citi, Comcast, Microsoft, Meta, and Target.

“Ironically, at least 109 of the .US domains in our data were used to attack the United States government, specifically the United States Postal Service and its customers,” Interisle wrote. “.US domains were also used to attack foreign government operations: six .US domains were used to attack Australian government services, six attacked Great’s Britain’s Royal Mail, one attacked Canada Post, and one attacked the Denmark Tax Authority.”

The NTIA recently published a proposal that would allow GoDaddy to redact registrant data from WHOIS registration records. The current charter for .US specifies that all .US registration records be public.

Interisle argues that without more stringent efforts to verify a United States nexus for new .US domain registrants, the NTIA’s proposal will make it even more difficult to identify phishers and verify registrants’ identities and nexus qualifications.

In a written statement, the NTIA said DNS abuse is a priority issue for the agency, and that NTIA supports “evidence-based policymaking.”

“We look forward to reviewing the report and will engage with our contractor for the .US domain on steps that we can take not only to address phishing, but the other forms of DNS abuse as well,” the statement reads.

Interisle sources its phishing data from several places, including the Anti-Phishing Working Group (APWG), OpenPhish, PhishTank, and Spamhaus. For more phishing facts, see Interisle’s 2023 Phishing Landscape report (PDF).’

Update, Sept. 5, 1:44 p.m. ET: Updated story with statement provided today by the NTIA.

U.S. Hacks QakBot, Quietly Removes Botnet Infections

By BrianKrebs

The U.S. government today announced a coordinated crackdown against QakBot, a complex malware family used by multiple cybercrime groups to lay the groundwork for ransomware infections. The international law enforcement operation involved seizing control over the botnet’s online infrastructure, and quietly removing the Qakbot malware from tens of thousands of infected Microsoft Windows computers.

In an international operation announced today dubbed “Duck Hunt,” the U.S. Department of Justice (DOJ) and Federal Bureau of Investigation (FBI) said they obtained court orders to remove Qakbot from infected devices, and to seize servers used to control the botnet.

“This is the most significant technological and financial operation ever led by the Department of Justice against a botnet,” said Martin Estrada, the U.S. attorney for the Southern District of California, at a press conference this morning in Los Angeles.

Estrada said Qakbot has been implicated in 40 different ransomware attacks over the past 18 months, intrusions that collectively cost victims more than $58 million in losses.

Emerging in 2007 as a banking trojan, QakBot (a.k.a. Qbot and Pinkslipbot) has morphed into an advanced malware strain now used by multiple cybercriminal groups to prepare newly compromised networks for ransomware infestations. QakBot is most commonly delivered via email phishing lures disguised as something legitimate and time-sensitive, such as invoices or work orders.

Don Alway, assistant director in charge of the FBI’s Los Angeles field office, said federal investigators gained access to an online panel that allowed cybercrooks to monitor and control the actions of the botnet. From there, investigators obtained court-ordered approval to instruct all infected systems to uninstall Qakbot and to disconnect themselves from the botnet, Alway said.

The DOJ says their access to the botnet’s control panel revealed that Qakbot had been used to infect more than 700,000 machines in the past year alone, including 200,000 systems in the United States.

Working with law enforcement partners in France, Germany, Latvia, the Netherlands, Romania and the United Kingdom, the DOJ said it was able to seize more than 50 Internet servers tied to the malware network, and nearly $9 million in ill-gotten cryptocurrency from QakBot’s cybercriminal overlords. The DOJ declined to say whether any suspects were questioned or arrested in connection with Qakbot, citing an ongoing investigation.

According to recent figures from the managed security firm Reliaquest, QakBot is by far the most prevalent malware “loader” — malicious software used to secure access to a hacked network and help drop additional malware payloads. Reliaquest says QakBot infections accounted for nearly one-third of all loaders observed in the wild during the first six months of this year.

Researchers at AT&T Alien Labs say the crooks responsible for maintaining the QakBot botnet have rented their creation to various cybercrime groups over the years. More recently, however, QakBot has been closely associated with ransomware attacks from Black Basta, a prolific Russian-language criminal group that was thought to have spun off from the Conti ransomware gang in early 2022.

Today’s operation is not the first time the U.S. government has used court orders to remotely disinfect systems compromised with malware. In May 2023, the DOJ quietly removed malware from computers around the world infected by the “Snake” malware, an even older malware family that has been tied to Russian intelligence agencies.

Documents published by the DOJ in support of today’s takedown state that beginning on Aug. 25, 2023, law enforcement gained access to the Qakbot botnet, redirected botnet traffic to and through servers controlled by law enforcement, and instructed Qakbot-infected computers to download a Qakbot Uninstall file that uninstalled Qakbot malware from the infected computer.

“The Qakbot Uninstall file did not remediate other malware that was already installed on infected computers,” the government explained. “Instead, it was designed to prevent additional Qakbot malware from being installed on the infected computer by untethering the victim computer from the Qakbot botnet.”

The DOJ said it also recovered more than 6.5 million stolen passwords and other credentials, and that it has shared this information with two websites that let users check to see if their credentials were exposed: Have I Been Pwned, and a “Check Your Hack” website erected by the Dutch National Police.

Tourists Give Themselves Away by Looking Up. So Do Most Network Intruders.

By BrianKrebs

In large metropolitan areas, tourists are often easy to spot because they’re far more inclined than locals to gaze upward at the surrounding skyscrapers. Security experts say this same tourist dynamic is a dead giveaway in virtually all computer intrusions that lead to devastating attacks like data theft and ransomware, and that more organizations should set simple virtual tripwires that sound the alarm when authorized users and devices are spotted exhibiting this behavior.

In a blog post published last month, Cisco Talos said it was seeing a worrisome “increase in the rate of high-sophistication attacks on network infrastructure.” Cisco’s warning comes amid a flurry of successful data ransom and state-sponsored cyber espionage attacks targeting some of the most well-defended networks on the planet.

But despite their increasing complexity, a great many initial intrusions that lead to data theft could be nipped in the bud if more organizations started looking for the telltale signs of newly-arrived cybercriminals behaving like network tourists, Cisco says.

“One of the most important things to talk about here is that in each of the cases we’ve seen, the threat actors are taking the type of ‘first steps’ that someone who wants to understand (and control) your environment would take,” Cisco’s Hazel Burton wrote. “Examples we have observed include threat actors performing a ‘show config,’ ‘show interface,’ ‘show route,’ ‘show arp table’ and a ‘show CDP neighbor.’ All these actions give the attackers a picture of a router’s perspective of the network, and an understanding of what foothold they have.”

Cisco’s alert concerned espionage attacks from China and Russia that abused vulnerabilities in aging, end-of-life network routers. But at a very important level, it doesn’t matter how or why the attackers got that initial foothold on your network.

It might be zero-day vulnerabilities in your network firewall or file-transfer appliance. Your more immediate and primary concern has to be: How quickly can you detect and detach that initial foothold?

The same tourist behavior that Cisco described attackers exhibiting vis-a-vis older routers is also incredibly common early on in ransomware and data ransom attacks — which often unfurl in secret over days or weeks as attackers methodically identify and compromise a victim’s key network assets.

These virtual hostage situations usually begin with the intruders purchasing access to the target’s network from dark web brokers who resell access to stolen credentials and compromised computers. As a result, when those stolen resources first get used by would-be data thieves, almost invariably the attackers will run a series of basic commands asking the local system to confirm exactly who and where they are on the victim’s network.

This fundamental reality about modern cyberattacks — that cybercriminals almost always orient themselves by “looking up” who and where they are upon entering a foreign network for the first time — forms the business model of an innovative security company called Thinkst, which gives away easy-to-use tripwires or “canaries” that can fire off an alert whenever all sorts of suspicious activity is witnessed.

“Many people have pointed out that there are a handful of commands that are overwhelmingly run by attackers on compromised hosts (and seldom ever by regular users/usage),” the Thinkst website explains. “Reliably alerting when a user on your code-sign server runs whoami.exe can mean the difference between catching a compromise in week-1 (before the attackers dig in) and learning about the attack on CNN.”

These canaries — or “canary tokens” — are meant to be embedded inside regular files, acting much like a web beacon or web bug that tracks when someone opens an email.

The Canary Tokens website from Thinkst Canary lists nearly two-dozen free customizable canaries.

“Imagine doing that, but for file reads, database queries, process executions or patterns in log files,” the Canary Tokens documentation explains. “Canarytokens does all this and more, letting you implant traps in your production systems rather than setting up separate honeypots.”

Thinkst operates alongside a burgeoning industry offering so-called “deception” or “honeypot” services — those designed to confuse, disrupt and entangle network intruders. But in an interview with KrebsOnSecurity, Thinkst founder and CEO Haroon Meer said most deception techniques involve some degree of hubris.

“Meaning, you’ll have deception teams in your network playing spy versus spy with people trying to break in, and it becomes this whole counterintelligence thing,” Meer said. “Nobody really has time for that. Instead, we are saying literally the opposite: That you’ve probably got all these [security improvement] projects that are going to take forever. But while you’re doing all that, just drop these 10 canaries, because everything else is going to take a long time to do.”

The idea here is to lay traps in sensitive areas of your network or web applications where few authorized users should ever trod. Importantly, the canary tokens themselves are useless to an attacker. For example, that AWS canary token sure looks like the digital keys to your cloud, but the token itself offers no access. It’s just a lure for the bad guys, and you get an alert when and if it is ever touched.

One nice thing about canary tokens is that Thinkst gives them away for free. Head over to canarytokens.org, and choose from a drop-down menu of available tokens, including:

-a web bug / URL token, designed to alert when a particular URL is visited;
-a DNS token, which alerts when a hostname is requested;
-an AWS token, which alerts when a specific Amazon Web Services key is used;
-a “custom exe” token, to alert when a specific Windows executable file or DLL is run;
-a “sensitive command” token, to alert when a suspicious Windows command is run.
-a Microsoft Excel/Word token, which alerts when a specific Excel or Word file is accessed.

Much like a “wet paint” sign often encourages people to touch a freshly painted surface anyway, attackers often can’t help themselves when they enter a foreign network and stumble upon what appear to be key digital assets, Meer says.

“If an attacker lands on your server and finds a key to your cloud environment, it’s really hard for them not to try it once,” Meer said. “Also, when these sorts of actors do land in a network, they have to orient themselves, and while doing that they are going to trip canaries.”

Meer says canary tokens are as likely to trip up attackers as they are “red teams,” security experts hired or employed by companies seeking to continuously probe their own computer systems and networks for security weaknesses.

“The concept and use of canary tokens has made me very hesitant to use credentials gained during an engagement, versus finding alternative means to an end goal,” wrote Shubham Shah, a penetration tester and co-founder of the security firm Assetnote. “If the aim is to increase the time taken for attackers, canary tokens work well.”

Thinkst makes money by selling Canary Tools, which are honeypots that emulate full blown systems like Windows servers or IBM mainframes. They deploy in minutes and include a personalized, private Canarytoken server.

“If you’ve got a sophisticated defense team, you can start putting these things in really interesting places,” Meer said. “Everyone says their stuff is simple, but we obsess over it. It’s really got to be so simple that people can’t mess it up. And if it works, it’s the best bang for your security buck you’re going to get.”

Karma Catches Up to Global Phishing Service 16Shop

By BrianKrebs

You’ve probably never heard of “16Shop,” but there’s a good chance someone using it has tried to phish you.

A 16Shop phishing page spoofing Apple and targeting Japanese users. Image: Akamai.com.

The international police organization INTERPOL said last week it had shuttered the notorious 16Shop, a popular phishing-as-a-service platform launched in 2017 that made it simple for even complete novices to conduct complex and convincing phishing scams. INTERPOL said authorities in Indonesia arrested the 21-year-old proprietor and one of his alleged facilitators, and that a third suspect was apprehended in Japan.

The INTERPOL statement says the platform sold hacking tools to compromise more than 70,000 users in 43 countries. Given how long 16Shop has been around and how many paying customers it enjoyed over the years, that number is almost certainly highly conservative.

Also, the sale of “hacking tools” doesn’t quite capture what 16Shop was all about: It was a fully automated phishing platform that gave its thousands of customers a series of brand-specific phishing kits to use, and provided the domain names needed to host the phishing pages and receive any stolen credentials.

Security experts investigating 16Shop found the service used an application programming interface (API) to manage its users, an innovation that allowed its proprietors to shut off access to customers who failed to pay a monthly fee, or for those attempting to copy or pirate the phishing kit.

16Shop also localized phishing pages in multiple languages, and the service would display relevant phishing content depending on the victim’s geolocation.

Various 16Shop lures for Apple users in different languages. Image: Akamai.

For example, in 2019 McAfee found that for targets in Japan, the 16Shop kit would also collect Web ID and Card Password, while US victims will be asked for their Social Security Number.

“Depending on location, 16Shop will also collect ID numbers (including Civil ID, National ID, and Citizen ID), passport numbers, social insurance numbers, sort codes, and credit limits,” McAfee wrote.

In addition, 16Shop employed various tricks to help its users’ phishing pages stay off the radar of security firms, including a local “blacklist” of Internet addresses tied to security companies, and a feature that allowed users to block entire Internet address ranges from accessing phishing pages.

The INTERPOL announcement does not name any of the suspects arrested in connection with the 16Shop investigation. However, a number of security firms — including Akamai, McAfee and ZeroFox, previously connected the service to a young Indonesian man named Riswanda Noor Saputra, who sold 16Shop under the hacker handle “Devilscream.”

According to the Indonesian security blog Cyberthreat.id, Saputra admitted being the administrator of 16Shop, but told the publication he handed the project off to others by early 2020.

Nevertheless, Cyberthreat reported that Devilscream was arrested by Indonesian police in late 2021 as part of a collaboration between INTERPOL and the U.S. Federal Bureau of Investigation (FBI). Still, researchers who tracked 16Shop since its inception say Devilscream was not the original proprietor of the phishing platform, and he may not be the last.

RIZKY BUSINESS

It is not uncommon for cybercriminals to accidentally infect their own machines with password-stealing malware, and that is exactly what seems to have happened with one of the more recent administrators of 16Shop.

Constella Intelligence, a data breach and threat actor research platform, now allows users to cross-reference popular cybercrime websites and denizens of these forums with inadvertent malware infections by information-stealing trojans. A search in Constella on 16Shop’s domain name shows that in mid-2022, a key administrator of the phishing service infected their Microsoft Windows desktop computer with the Redline information stealer trojan — apparently by downloading a cracked (and secretly backdoored) copy of Adobe Photoshop.

Redline infections steal gobs of data from the victim machine, including a list of recent downloads, stored passwords and authentication cookies, as well as browser bookmarks and auto-fill data. Those records indicate the 16Shop admin used the nicknames “Rudi” and “Rizki/Rizky,” and maintained several Facebook profiles under these monikers.

It appears this user’s full name (or at least part of it) is Rizky Mauluna Sidik, and they are from Bandung in West Java, Indonesia. One of this user’s Facebook pages says Rizky is the chief executive officer and founder of an entity called BandungXploiter, whose Facebook page indicates it is a group focused mainly on hacking and defacing websites.

A LinkedIn profile for Rizky says he is a backend Web developer in Bandung who earned a bachelor’s degree in information technology in 2020. Mr. Rizky did not respond to requests for comment.

What's the State of Credential theft in 2023?

Diligere, Equity-Invest Are New Firms of U.K. Con Man

By BrianKrebs

John Clifton Davies, a convicted fraudster estimated to have bilked dozens of technology startups out of more than $30 million through phony investment schemes, has a brand new pair of scam companies that are busy dashing startup dreams: A fake investment firm called Equity-Invest[.]ch, and Diligere[.]co.uk, a scam due diligence company that Equity-Invest insists all investment partners use.

A native of the United Kingdom, Mr. Davies absconded from justice before being convicted on multiple counts of fraud in 2015. Prior to his conviction, Davies served 16 months in jail before being cleared on suspicion of murdering his third wife on their honeymoon in India.

The scam artist John Bernard (left) in a recent Zoom call, and a photo of John Clifton Davies from 2015.

John Clifton Davies was convicted in 2015 of swindling businesses throughout the U.K. that were struggling financially and seeking to restructure their debt. For roughly six years, Davies ran a series of firms that pretended to offer insolvency services. Instead, he simply siphoned what little remaining money these companies had, spending the stolen funds on lavish cars, home furnishings, vacations and luxury watches.

In a three-part series published in 2020, KrebsOnSecurity exposed how Davies — wanted by authorities in the U.K. — had fled the country, taken on the surname Bernard, remarried, and moved to his new (and fourth) wife’s hometown in Ukraine.

After eluding justice in the U.K., Davies reinvented himself as The Private Office of John Bernard, pretending to be a billionaire Swiss investor who made his fortunes in the dot-com boom 20 years ago and who was seeking private equity investment opportunities.

In case after case, Bernard would promise to invest millions in hi-tech startups, only to insist that companies pay tens of thousands of dollars worth of due diligence fees up front. However, the due diligence company he insisted on using — another Swiss firm called The Inside Knowledge — also was secretly owned by Bernard, who would invariably pull out of the deal after receiving the due diligence money.

Bernard found a constant stream of new marks by offering extraordinarily generous finders fees to investment brokers who could introduce him to companies seeking an infusion of cash. Inside Knowledge and The Private Office both closed up shop not long after being exposed here in 2020.

In April 2023, KrebsOnSecurity wrote about Codes2You, a recent Davies venture which purports to be a “full cycle software development company” based in the U.K. The company’s website no longer lists any of Davies’ known associates, but the site does still reference software and cloud services tied to those associates — including MySolve, a “multi-feature platform for insolvency practitioners.”

Earlier this month, KrebsOnSecurity heard from an investment broker who found out his client had paid more than $50,000 in due diligence fees related to a supposed multi-million dollar investment offer from a Swiss concern called Equity-Invest[.]ch.

The investment broker, who spoke on condition that neither he nor his client be named, said Equity-Invest began getting cold feet after his client plunked down the due diligence fees.

“Things started to go sideways when the investor purportedly booked a trip to the US to meet the team but canceled last minute because ‘his pregnant wife got in a car accident,'” the broker explained. “After that, he was radio silent until the contract expired.”

The broker said he grew suspicious when he learned that the Equity-Invest domain name was less than six months old. The broker’s suspicions were confirmed after he discovered the due diligence company that Equity-Invest insisted on using — Diligere[.]co.uk — included an email address on its homepage for another entity called Ardelis Solutions.

A corporate entity in the UK called Ardelis Solutions was key to showing the connection to Davies’ former scam investment and due diligence firms in the Codes2You investigation published earlier this year.

Although Diligere’s website claims the due diligence firm has “13 years of experiance” [sic], its domain name was only registered in April 2023. What’s more, virtually all of the vapid corporate-speak published on Diligere’s homepage is identical to text on the now-defunct InsideKnowledge[.]ch — the fake due diligence firm secretly owned for many years by The Private Office of John Bernard (John Clifton Davies).

A snippet of text from the now-defunct website of the fake Swiss investor John Bernard, in real life John Clifton Davies.

“Our steadfast conviction and energy for results is what makes us stand out,” both sites state. “We care for our clients’ and their businesses, we share their ambitions and align our goals to complement their objectives. Our clients know we’re in this together. We work in close partnership with our clients to deliver palpable results regardless of geography, complexity or controversy.”

The copy on Diligere’s homepage is identical to that once on Insideknowledge[.]com, a phony due diligence company run by John Clifton Davies.

Requests for comment sent to the contact address listed on Diligere — info@ardelissolutions[.]com — went unreturned. Equity-Invest did not respond to requests for comment.

Meet the Brains Behind the Malware-Friendly AI Chat Service ‘WormGPT’

By BrianKrebs

WormGPT, a private new chatbot service advertised as a way to use Artificial Intelligence (AI) to write malicious software without all the pesky prohibitions on such activity enforced by the likes of ChatGPT and Google Bard, has started adding restrictions of its own on how the service can be used. Faced with customers trying to use WormGPT to create ransomware and phishing scams, the 23-year-old Portuguese programmer who created the project now says his service is slowly morphing into “a more controlled environment.”

Image: SlashNext.com.

The large language models (LLMs) made by ChatGPT parent OpenAI or Google or Microsoft all have various safety measures designed to prevent people from abusing them for nefarious purposes — such as creating malware or hate speech. In contrast, WormGPT has promoted itself as a new, uncensored LLM that was created specifically for cybercrime activities.

WormGPT was initially sold exclusively on HackForums, a sprawling, English-language community that has long featured a bustling marketplace for cybercrime tools and services. WormGPT licenses are sold for prices ranging from 500 to 5,000 Euro.

“Introducing my newest creation, ‘WormGPT,’ wrote “Last,” the handle chosen by the HackForums user who is selling the service. “This project aims to provide an alternative to ChatGPT, one that lets you do all sorts of illegal stuff and easily sell it online in the future. Everything blackhat related that you can think of can be done with WormGPT, allowing anyone access to malicious activity without ever leaving the comfort of their home.”

In July, an AI-based security firm called SlashNext analyzed WormGPT and asked it to create a “business email compromise” (BEC) phishing lure that could be used to trick employees into paying a fake invoice.

“The results were unsettling,” SlashNext’s Daniel Kelley wrote. “WormGPT produced an email that was not only remarkably persuasive but also strategically cunning, showcasing its potential for sophisticated phishing and BEC attacks.”

SlashNext asked WormGPT to compose this BEC phishing email. Image: SlashNext.

A review of Last’s posts on HackForums over the years shows this individual has extensive experience creating and using malicious software. In August 2022, Last posted a sales thread for “Arctic Stealer,” a data stealing trojan and keystroke logger that he sold there for many months.

“I’m very experienced with malwares,” Last wrote in a message to another HackForums user last year.

Last has also sold a modified version of the information stealer DCRat, as well as an obfuscation service marketed to malicious coders who sell their creations and wish to insulate them from being modified or copied by customers.

Shortly after joining the forum in early 2021, Last told several different Hackforums users his name was Rafael and that he was from Portugal. HackForums has a feature that allows anyone willing to take the time to dig through a user’s postings to learn when and if that user was previously tied to another account.

That account tracing feature reveals that while Last has used many pseudonyms over the years, he originally used the nickname “ruiunashackers.” The first search result in Google for that unique nickname brings up a TikTok account with the same moniker, and that TikTok account says it is associated with an Instagram account for a Rafael Morais from Porto, a coastal city in northwest Portugal.

AN OPEN BOOK

Reached via Instagram and Telegram, Morais said he was happy to chat about WormGPT.

“You can ask me anything,” Morais said. “I’m an open book.”

Morais said he recently graduated from a polytechnic institute in Portugal, where he earned a degree in information technology. He said only about 30 to 35 percent of the work on WormGPT was his, and that other coders are contributing to the project. So far, he says, roughly 200 customers have paid to use the service.

“I don’t do this for money,” Morais explained. “It was basically a project I thought [was] interesting at the beginning and now I’m maintaining it just to help [the] community. We have updated a lot since the release, our model is now 5 or 6 times better in terms of learning and answer accuracy.”

WormGPT isn’t the only rogue ChatGPT clone advertised as friendly to malware writers and cybercriminals. According to SlashNext, one unsettling trend on the cybercrime forums is evident in discussion threads offering “jailbreaks” for interfaces like ChatGPT.

“These ‘jailbreaks’ are specialised prompts that are becoming increasingly common,” Kelley wrote. “They refer to carefully crafted inputs designed to manipulate interfaces like ChatGPT into generating output that might involve disclosing sensitive information, producing inappropriate content, or even executing harmful code. The proliferation of such practices underscores the rising challenges in maintaining AI security in the face of determined cybercriminals.”

Morais said they have been using the GPT-J 6B model since the service was launched, although he declined to discuss the source of the LLMs that power WormGPT. But he said the data set that informs WormGPT is enormous.

“Anyone that tests wormgpt can see that it has no difference from any other uncensored AI or even chatgpt with jailbreaks,” Morais explained. “The game changer is that our dataset [library] is big.”

Morais said he began working on computers at age 13, and soon started exploring security vulnerabilities and the possibility of making a living by finding and reporting them to software vendors.

“My story began in 2013 with some greyhat activies, never anything blackhat tho, mostly bugbounty,” he said. “In 2015, my love for coding started, learning c# and more .net programming languages. In 2017 I’ve started using many hacking forums because I have had some problems home (in terms of money) so I had to help my parents with money… started selling a few products (not blackhat yet) and in 2019 I started turning blackhat. Until a few months ago I was still selling blackhat products but now with wormgpt I see a bright future and have decided to start my transition into whitehat again.”

WormGPT sells licenses via a dedicated channel on Telegram, and the channel recently lamented that media coverage of WormGPT so far has painted the service in an unfairly negative light.

“We are uncensored, not blackhat!” the WormGPT channel announced at the end of July. “From the beginning, the media has portrayed us as a malicious LLM (Language Model), when all we did was use the name ‘blackhatgpt’ for our Telegram channel as a meme. We encourage researchers to test our tool and provide feedback to determine if it is as bad as the media is portraying it to the world.”

It turns out, when you advertise an online service for doing bad things, people tend to show up with the intention of doing bad things with it. WormGPT’s front man Last seems to have acknowledged this at the service’s initial launch, which included the disclaimer, “We are not responsible if you use this tool for doing bad stuff.”

But lately, Morais said, WormGPT has been forced to add certain guardrails of its own.

“We have prohibited some subjects on WormGPT itself,” Morais said. “Anything related to murders, drug traffic, kidnapping, child porn, ransomwares, financial crime. We are working on blocking BEC too, at the moment it is still possible but most of the times it will be incomplete because we already added some limitations. Our plan is to have WormGPT marked as an uncensored AI, not blackhat. In the last weeks we have been blocking some subjects from being discussed on WormGPT.”

Still, Last has continued to state on HackForums — and more recently on the far more serious cybercrime forum Exploit — that WormGPT will quite happily create malware capable of infecting a computer and going “fully undetectable” (FUD) by virtually all of the major antivirus makers (AVs).

“You can easily buy WormGPT and ask it for a Rust malware script and it will 99% sure be FUD against most AVs,” Last told a forum denizen in late July.

Asked to list some of the legitimate or what he called “white hat” uses for WormGPT, Morais said his service offers reliable code, unlimited characters, and accurate, quick answers.

“We used WormGPT to fix some issues on our website related to possible sql problems and exploits,” he explained. “You can use WormGPT to create firewalls, manage iptables, analyze network, code blockers, math, anything.”

Morais said he wants WormGPT to become a positive influence on the security community, not a destructive one, and that he’s actively trying to steer the project in that direction. The original HackForums thread pimping WormGPT as a malware writer’s best friend has since been deleted, and the service is now advertised as “WormGPT – Best GPT Alternative Without Limits — Privacy Focused.”

“We have a few researchers using our wormgpt for whitehat stuff, that’s our main focus now, turning wormgpt into a good thing to [the] community,” he said.

It’s unclear yet whether Last’s customers share that view.

How Malicious Android Apps Slip Into Disguise

By BrianKrebs

Researchers say mobile malware purveyors have been abusing a bug in the Google Android platform that lets them sneak malicious code into mobile apps and evade security scanning tools. Google says it has updated its app malware detection mechanisms in response to the new research.

At issue is a mobile malware obfuscation method identified by researchers at ThreatFabric, a security firm based in Amsterdam. Aleksandr Eremin, a senior malware analyst at the company, told KrebsOnSecurity they recently encountered a number of mobile banking trojans abusing a bug present in all Android OS versions that involves corrupting components of an app so that its new evil bits will be ignored as invalid by popular mobile security scanning tools, while the app as a whole gets accepted as valid by Android OS and successfully installed.

“There is malware that is patching the .apk file [the app installation file], so that the platform is still treating it as valid and runs all the malicious actions it’s designed to do, while at the same time a lot of tools designed to unpack and decompile these apps fail to process the code,” Eremin explained.

Eremin said ThreatFabric has seen this malware obfuscation method used a few times in the past, but in April 2023 it started finding many more variants of known mobile malware families leveraging it for stealth. The company has since attributed this increase to a semi-automated malware-as-a-service offering in the cybercrime underground that will obfuscate or “crypt” malicious mobile apps for a fee.

Eremin said Google flagged their initial May 9, 2023 report as “high” severity. More recently, Google awarded them a $5,000 bug bounty, even though it did not technically classify their finding as a security vulnerability.

“This was a unique situation in which the reported issue was not classified as a vulnerability and did not impact the Android Open Source Project (AOSP), but did result in an update to our malware detection mechanisms for apps that might try to abuse this issue,” Google said in a written statement.

Google also acknowledged that some of the tools it makes available to developers — including APK Analyzer — currently fail to parse such malicious applications and treat them as invalid, while still allowing them to be installed on user devices.

“We are investigating possible fixes for developer tools and plan to update our documentation accordingly,” Google’s statement continued.

According to ThreatFabric, there are a few telltale signs that app analyzers can look for that may indicate a malicious app is abusing the weakness to masquerade as benign. For starters, they found that apps modified in this way have Android Manifest files that contain newer timestamps than the rest of the files in the software package.

More critically, the Manifest file itself will be changed so that the number of “strings” — plain text in the code, such as comments — specified as present in the app does match the actual number of strings in the software.

One of the mobile malware families known to be abusing this obfuscation method has been dubbed Anatsa, which is a sophisticated Android-based banking trojan that typically is disguised as a harmless application for managing files. Last month, ThreatFabric detailed how the crooks behind Anatsa will purchase older, abandoned file managing apps, or create their own and let the apps build up a considerable user base before updating them with malicious components.

ThreatFabric says Anatsa poses as PDF viewers and other file managing applications because these types of apps already have advanced permissions to remove or modify other files on the host device. The company estimates the people behind Anatsa have delivered more than 30,000 installations of their banking trojan via ongoing Google Play Store malware campaigns.

Google has come under fire in recent months for failing to more proactively police its Play Store for malicious apps, or for once-legitimate applications that later go rogue. This May 2023 story from Ars Technica about a formerly benign screen recording app that turned malicious after garnering 50,000 users notes that Google doesn’t comment when malware is discovered on its platform, beyond thanking the outside researchers who found it and saying the company removes malware as soon as it learns of it.

“The company has never explained what causes its own researchers and automated scanning process to miss malicious apps discovered by outsiders,” Ars’ Dan Goodin wrote. “Google has also been reluctant to actively notify Play users once it learns they were infected by apps promoted and made available by its own service.”

The Ars story mentions one potentially positive change by Google of late: A preventive measure available in Android versions 11 and higher that implements “app hibernation,” which puts apps that have been dormant into a hibernation state that removes their previously granted runtime permissions.

Russia Sends Cybersecurity CEO to Jail for 14 Years

By BrianKrebs

The Russian government today handed down a treason conviction and 14-year prison sentence on Iyla Sachkov, the former founder and CEO of one of Russia’s largest cybersecurity firms. Sachkov, 37, has been detained for nearly two years under charges that the Kremlin has kept classified and hidden from public view, and he joins a growing roster of former Russian cybercrime fighters who are now serving hard time for farcical treason convictions.

In 2003, Sachkov founded Group-IB, a cybersecurity and digital forensics company that quickly earned a reputation for exposing and disrupting large-scale cybercrime operations, including quite a few that were based in Russia and stealing from Russian companies and citizens.

In September 2021, the Kremlin issued treason charges against Sachkov, although it has refused to disclose any details about the allegations. Sachkov pleaded not guilty. After a three-week “trial” that was closed to the public, Sachkov was convicted of treason and sentenced to 14 years in prison. Prosecutors had asked for 18 years.

Group-IB relocated its headquarters to Singapore several years ago, although it did not fully exit the Russian market until April 2023. In a statement, Group-IB said that during their founder’s detainment, he was denied the right to communicate — no calls, no letters — with the outside world for the first few months, and was deprived of any visits from family and friends.

“Ultimately, Ilya has been denied a chance for an impartial trial,” reads a blog post on the company’s site. “All the materials of the case are kept classified, and all hearings were held in complete secrecy with no public scrutiny. As a result, we might never know the pretext for his conviction.”

Prior to his arrest in 2021, Sachkov publicly chastised the Kremlin for turning a blind eye to the epidemic of ransomware attacks coming from Russia. In a speech covered by the Financial Times in 2021, Sachkov railed against the likes of Russian hacker Maksim Yakubets, the accused head of a hacking group called Evil Corp. that U.S. officials say has stolen hundreds of millions of dollars over the past decade.

“Yakubets has been spotted driving around Moscow in a fluorescent camouflage Lamborghini, with a custom licence plate that reads ‘THIEF,'” FT’s Max Seddon wrote. “He also ‘provides direct assistance to the Russian government’s malicious cyber efforts,’ according to US Treasury sanctions against him.”

In December 2021, Bloomberg reported that Sachkov was alleged to have given the United States information about the Russian “Fancy Bear” operation that sought to influence the 2016 U.S. election. Fancy Bear is one of several names (e.g., APT28) for an advanced Russian cyber espionage group that has been linked to the Russian military intelligence agency GRU.

In 2019, a Moscow court meted out a 22-year prison sentence for alleged treason charges against Sergei Mikhailov, formerly deputy chief of Russia’s top anti-cybercrime unit. The court also levied a 14-year sentence against Ruslan Stoyanov, a senior employee at Kaspersky Lab. Both men maintained their innocence throughout the trial, and the supposed reason for the treason charges has never been disclosed.

Following their dramatic arrests in 2016, some media outlets reported that the men were suspected of having tipped off American intelligence officials about those responsible for Russian hacking activities tied to the 2016 U.S. presidential election.

That’s because two others arrested for treason at the same time — Mikhailov subordinates Georgi Fomchenkov and Dmitry Dokuchaev — were reported by Russian media to have helped the FBI investigate Russian servers linked to the 2016 hacking of the Democratic National Committee.

Who and What is Behind the Malware Proxy Service SocksEscort?

By BrianKrebs

Researchers this month uncovered a two-year-old Linux-based remote access trojan dubbed AVrecon that enslaves Internet routers into botnet that bilks online advertisers and performs password-spraying attacks. Now new findings reveal that AVrecon is the malware engine behind a 12-year-old service called SocksEscort, which rents hacked residential and small business devices to cybercriminals looking to hide their true location online.

Image: Lumen’s Black Lotus Labs.

In a report released July 12, researchers at Lumen’s Black Lotus Labs called the AVrecon botnet “one of the largest botnets targeting small-office/home-office (SOHO) routers seen in recent history,” and a crime machine that has largely evaded public attention since first being spotted in mid-2021.

“The malware has been used to create residential proxy services to shroud malicious activity such as password spraying, web-traffic proxying and ad fraud,” the Lumen researchers wrote.

Malware-based anonymity networks are a major source of unwanted and malicious web traffic directed at online retailers, Internet service providers (ISPs), social networks, email providers and financial institutions. And a great many of these “proxy” networks are marketed primarily to cybercriminals seeking to anonymize their traffic by routing it through an infected PC, router or mobile device.

Proxy services can be used in a legitimate manner for several business purposes — such as price comparisons or sales intelligence — but they are massively abused for hiding cybercrime activity because they make it difficult to trace malicious traffic to its original source. Proxy services also let users appear to be getting online from nearly anywhere in the world, which is useful if you’re a cybercriminal who is trying to impersonate someone from a specific place.

Spur.us, a startup that tracks proxy services, told KrebsOnSecurity that the Internet addresses Lumen tagged as the AVrecon botnet’s “Command and Control” (C2) servers all tie back to a long-running proxy service called SocksEscort.

SocksEscort[.]com, is what’s known as a “SOCKS Proxy” service. The SOCKS (or SOCKS5) protocol allows Internet users to channel their Web traffic through a proxy server, which then passes the information on to the intended destination. From a website’s perspective, the traffic of the proxy network customer appears to originate from a rented/malware-infected PC tied to a residential ISP customer, not from the proxy service customer.

The SocksEscort home page says its services are perfect for people involved in automated online activity that often results in IP addresses getting blocked or banned, such as Craigslist and dating scams, search engine results manipulation, and online surveys.

Spur tracks SocksEscort as a malware-based proxy offering, which means the machines doing the proxying of traffic for SocksEscort customers have been infected with malicious software that turns them into a traffic relay. Usually, these users have no idea their systems are compromised.

Spur says the SocksEscort proxy service requires customers to install a Windows based application in order to access a pool of more than 10,000 hacked devices worldwide.

“We created a fingerprint to identify the call-back infrastructure for SocksEscort proxies,” Spur co-founder Riley Kilmer said. “Looking at network telemetry, we were able to confirm that we saw victims talking back to it on various ports.”

According to Kilmer, AVrecon is the malware that gives SocksEscort its proxies.

“When Lumen released their report and IOCs [indicators of compromise], we queried our system for which proxy service call-back infrastructure overlapped with their IOCs,” Kilmer continued. “The second stage C2s they identified were the same as the IPs we labeled for SocksEscort.”

Lumen’s research team said the purpose of AVrecon appears to be stealing bandwidth – without impacting end-users – in order to create a residential proxy service to help launder malicious activity and avoid attracting the same level of attention from Tor-hidden services or commercially available VPN services.

“This class of cybercrime activity threat may evade detection because it is less likely than a crypto-miner to be noticed by the owner, and it is unlikely to warrant the volume of abuse complaints that internet-wide brute-forcing and DDoS-based botnets typically draw,” Lumen’s Black Lotus researchers wrote.

Preserving bandwidth for both customers and victims was a primary concern for SocksEscort in July 2022, when 911S5 — at the time the world’s largest known malware proxy network — got hacked and imploded just days after being exposed in a story here. Kilmer said after 911’s demise, SocksEscort closed its registration for several months to prevent an influx of new users from swamping the service.

Danny Adamitis, principal information security researcher at Lumen and co-author of the report on AVrecon, confirmed Kilmer’s findings, saying the C2 data matched up with what Spur was seeing for SocksEscort dating back to September 2022.

Adamitis said that on July 13 — the day after Lumen published research on AVrecon and started blocking any traffic to the malware’s control servers — the people responsible for maintaining the botnet reacted quickly to transition infected systems over to a new command and control infrastructure.

“They were clearly reacting and trying to maintain control over components of the botnet,” Adamitis said. “Probably, they wanted to keep that revenue stream going.”

Frustratingly, Lumen was not able to determine how the SOHO devices were being infected with AVrecon. Some possible avenues of infection include exploiting weak or default administrative credentials on routers, and outdated, insecure firmware that has known, exploitable security vulnerabilities.

WHO’S BEHIND SOCKSESCORT?

KrebsOnSecurity briefly visited SocksEscort last year and promised a follow-up on the history and possible identity of its proprietors. A review of the earliest posts about this service on Russian cybercrime forums suggests the 12-year-old malware proxy network is tied to a Moldovan company that also offers VPN software on the Apple Store and elsewhere.

SocksEscort began in 2009 as “super-socks[.]com,” a Russian-language service that sold access to thousands of compromised PCs that could be used to proxy traffic. Someone who picked the nicknames “SSC” and “super-socks” and email address “michvatt@gmail.com” registered on multiple cybercrime forums and began promoting the proxy service.

According to DomainTools.com, the apparently related email address “michdomain@gmail.com” was used to register SocksEscort[.]com, super-socks[.]com, and a few other proxy-related domains, including ip-score[.]com, segate[.]org seproxysoft[.]com, and vipssc[.]us. Cached versions of both super-socks[.]com and vipssc[.]us show these sites sold the same proxy service, and both displayed the letters “SSC” prominently at the top of their homepages.

Image: Archive.org. Page translation from Russian via Google Translate.

According to cyber intelligence firm Intel 471, the very first “SSC” identity registered on the cybercrime forums happened in 2009 at the Russian language hacker community Antichat, where SSC asked fellow forum members for help in testing the security of a website they claimed was theirs: myiptest[.]com, which promised to tell visitors whether their proxy address was included on any security or anti-spam block lists.

Myiptest[.]com is no longer responding, but a cached copy of it from Archive.org shows that for about four years it included in its HTML source a Google Analytics code of US-2665744, which was also present on more than a dozen other websites.

Most of the sites that once bore that Google tracking code are no longer online, but nearly all of them centered around services that were similar to myiptest[.]com, such as abuseipdb[.]com, bestiptest[.]com, checkdnslbl[.]com, dnsbltools[.]com and dnsblmonitor[.]com.

Each of these services were designed to help visitors quickly determine whether the Internet address they were visiting the site from was listed by any security firms as spammy, malicious or phishous. In other words, these services were designed so that proxy service users could easily tell if their rented Internet address was still safe to use for online fraud.

Another domain with the Google Analytics code US-2665744 was sscompany[.]net. An archived copy of the site says SSC stands for “Server Support Company,” which advertised outsourced solutions for technical support and server administration.

Leaked copies of the hacked Antichat forum indicate the SSC identity registered on the forum using the IP address 71.229.207.214. That same IP was used to register the nickname “Deem3n®,” a prolific poster on Antichat between 2005 and 2009 who served as a moderator on the forum.

There was a Deem3n® user on the webmaster forum Searchengines.guru whose signature in their posts says they run a popular community catering to programmers in Moldova called sysadmin[.]md, and that they were a systems administrator for sscompany[.]net.

That same Google Analytics code is also now present on the homepages of wiremo[.]co and a VPN provider called HideIPVPN[.]com.

Wiremo sells software and services to help website owners better manage their customer reviews. Wiremo’s Contact Us page lists a “Server Management LLC” in Wilmington, DE as the parent company. Server Management LLC is currently listed in Apple’s App Store as the owner of a “free” VPN app called HideIPVPN.

“The best way to secure the transmissions of your mobile device is VPN,” reads HideIPVPN’s description on the Apple Store. “Now, we provide you with an even easier way to connect to our VPN servers. We will hide your IP address, encrypt all your traffic, secure all your sensitive information (passwords, mail credit card details, etc.) form [sic] hackers on public networks.”

When asked about the company’s apparent connection to SocksEscort, Wiremo responded, “We do not control this domain and no one from our team is connected to this domain.” Wiremo did not respond when presented with the findings in this report.

LeakedSource Owner Quit Ashley Madison a Month Before 2015 Hack

By BrianKrebs

[This is Part III in a series on research conducted for a recent Hulu documentary on the 2015 hack of marital infidelity website AshleyMadison.com.]

In 2019, a Canadian company called Defiant Tech Inc. pleaded guilty to running LeakedSource[.]com, a service that sold access to billions of passwords and other data exposed in countless data breaches. KrebsOnSecurity has learned that the owner of Defiant Tech, a 32-year-old Ontario man named Jordan Evan Bloom, was hired in late 2014 as a developer for the marital infidelity site AshleyMadison.com. Bloom resigned from AshleyMadison citing health reasons in June 2015 — less than one month before unidentified hackers stole data on 37 million users — and launched LeakedSource three months later.

Jordan Evan Bloom, posing in front of his Lamborghini.

On Jan. 15, 2018, the Royal Canadian Mounted Police (RCMP) charged then 27-year-old Bloom, of Thornhill, Ontario, with selling stolen personal identities online through the website LeakedSource[.]com.

LeakedSource was advertised on a number of popular cybercrime forums as a service that could help hackers break into valuable or high-profile accounts. LeakedSource also tried to pass itself off as a legal, legitimate business that was marketing to security firms and professionals.

The RCMP arrested Bloom in December 2017, and said he made approximately $250,000 selling hacked data, which included information on 37 million user accounts leaked in the 2015 Ashley Madison breach.

Subsequent press releases from the RCMP about the LeakedSource investigation omitted any mention of Bloom, and referred to the defendant only as Defiant Tech. In a legal settlement that is quintessentially Canadian, the matter was resolved in 2019 after Defiant Tech agreed to plead guilty. The RCMP declined to comment for this story.

A GREY MARKET

The Impact Team, the hacker group that claimed responsibility for stealing and leaking the AshleyMadison user data, also leaked several years worth of email from then-CEO Noel Biderman. A review of those messages shows that Ashley Madison hired Jordan Evan Bloom as a PHP developer in December 2014 — even though the company understood that Bloom’s success as a programmer and businessman was tied to shady and legally murky enterprises.

Bloom’s recommendation came to Biderman via Trevor Sykes, then chief technology officer for Ashley Madison parent firm Avid Life Media (ALM). The following is an email from Sykes to Biderman dated Nov. 14, 2014:

“Greetings Noel,

“We’d like to offer Jordan Bloom the position of PHP developer reporting to Mike Morris for 75k CAD/Year. He did well on the test, but he also has a great understanding of the business side of things having run small businesses himself. This was an internal referral.”

When Biderman responded that he needed more information about the candidate, Sykes replied that Bloom was independently wealthy as a result of his forays into the shadowy world of “gold farming”  — the semi-automated use of large numbers of player accounts to win some advantage that is usually related to cashing out game accounts or inventory. Gold farming is particularly prevalent in massively multiplayer online role-playing games (MMORPGs), such as RuneScape and World of Warcraft.

“In his previous experience he had been doing RMT (Real Money Trading),” Sykes wrote. “This is the practice of selling virtual goods in games for real world money. This is a grey market, which is usually against the terms and services of the game companies.” Here’s the rest of his message to Biderman:

“RMT sellers traditionally have a lot of problems with chargebacks, and payment processor compliance. During my interview with him, I spent some time focusing in on this. He had to demonstrate to the processor, Paypal, at the time he had a business and technical strategy to address his charge back rate.”

“He ran this company himself, and did all the coding, including the integration with the processors,” Sykes continued in his assessment of Bloom. “Eventually he was squeezed out by Chinese gold farmers, and their ability to market with much more investment than he could. In addition the cost of ‘farming’ the virtual goods was cheaper in China to do than in North America.”

COME, ABUSE WITH US

The gold farming reference is fascinating because in 2017 KrebsOnSecurity published Who Ran LeakedSource?, which examined clues suggesting that one of the administrators of LeakedSource also was the admin of abusewith[.]us, a site unabashedly dedicated to helping people hack email and online gaming accounts.

An administrator account Xerx3s on Abusewithus.

Abusewith[.]us began in September 2013 as a forum for learning and teaching how to hack accounts at Runescape, an MMORPG set in a medieval fantasy realm where players battle for kingdoms and riches.

The currency with which Runescape players buy and sell weapons, potions and other in-game items are virtual gold coins, and many of Abusewith[dot]us’s early members traded in a handful of commodities: Phishing kits and exploits that could be used to steal Runescape usernames and passwords from fellow players; virtual gold plundered from hacked accounts; and databases from hacked forums and websites related to Runescape and other online games.

That 2017 report here interviewed a Michigan man who acknowledged being administrator of Abusewith[.]us, but denied being the operator of LeakedSource. Still, the story noted that LeakedSource likely had more than one operator, and breached records show Bloom was a prolific member of Abusewith[.]us.

In an email to all employees on Dec. 1, 2014, Ashley Madison’s director of HR said Bloom graduated from York University in Toronto with a degree in theoretical physics, and that he has been an active programmer since high school.

“He’s a proprietor of a high traffic multiplayer game and developer/publisher of utilities such as PicTrace,” the HR director enthused. “He will be a great addition to the team.”

PicTrace appears to have been a service that allowed users to glean information about anyone who viewed an image hosted on the platform, such as their Internet address, browser type and version number. A copy of pictrace[.]com from Archive.org in 2012 redirects to the domain qksnap.com, which DomainTools.com says was registered to a Jordan Bloom from Thornhill, ON that same year.

The street address listed in the registration records for qksnap.com — 204 Beverley Glen Blvd — also shows up in the registration records for leakadvisor[.]com, a domain registered in 2017 just months after Canadian authorities seized the servers running LeakedSource.

Pictrace, one of Jordan Bloom’s early IT successes.

A review of passive DNS records from DomainTools indicates that in 2013 pictrace[.]com shared a server with just a handful of other domains, including Near-Reality[.]com — a popular RuneScape Private Server (RSPS) game based on the RuneScape MMORPG.

Copies of near-reality[.]com from 2013 via Archive.org show the top of the community’s homepage was retrofitted with a message saying Near Reality was no longer available due to a copyright dispute. Although the site doesn’t specify the other party to the copyright dispute, it appears Near-Reality got sued by Jagex, the owner of RuneScape.

The message goes on to say the website will no longer “encourage, facilitate, enable or condone (i) any infringement of copyright in RuneScape or any other Jagex product; nor (ii) any breach of the terms and conditions of RuneScape or any other Jagex product.”

A scene from the MMORPG RuneScape.

AGENTJAGS

Near Reality also has a Facebook page that was last updated in 2019, when its owner posted a link to a news story about Defiant Tech’s guilty plea in the LeakedSource investigation. That Facebook page indicates Bloom also went by the nickname “Agentjags.”

“Just a quick PSA,” reads a post to the Near Reality Facebook page dated Jan. 21, 2018, which linked to a story about the charges against Bloom and a photo of Bloom standing in front of his lime-green Lamborghini. “Agentjags has got involved in some shady shit that may have compromised your personal details. I advise anyone who is using an old NR [Near Reality] password for anything remotely important should change it ASAP.”

By the beginning of 2016, Bloom was nowhere to be found, and was suspected of having fled his country for the Caribbean, according to the people commenting on the Near Reality Facebook page:

“Jordan aka Agentjags has gone missing,” wrote a presumed co-owner of the Facebook page. “He is supposedly hiding in St. Lucia, doing what he loved, scuba-diving. Any information to his whereabouts will be appreciated.”

KrebsOnSecurity ran the unusual nickname “AgentJags” through a search at Constella Intelligence, a commercial service that tracks breached data sets. That search returned just a few dozen results — and virtually all were accounts at various RuneScape-themed sites, including a half-dozen accounts at Abusewith[.]us.

Constella found other “AgentJags” accounts tied to the email address ownagegaming1@gmail.com. The marketing firm Apollo.io experienced a data breach several years back, and according to Apollo the email address ownagegaming1@gmail.com belongs to Jordan Bloom in Ontario.

Constella also revealed that the password frequently used by ownagegaming1@gmail.com across many sites was some variation on “niggapls,” which my 2017 report found was also the password used by the administrator of LeakedSource.

Constella discovered that the email eric.malek@rogers.com comes up when one searches for “AgentJags.” This is curious because emails leaked from Ashley Madison’s then-CEO Biderman show that Eric Malek from Toronto was the Ashley Madison employee who initially recommended Bloom for the PHP developer job.

According to DomainTools.com, Eric.Malek@rogers.com was used to register the domain devjobs.ca, which previously advertised “the most exciting developer jobs in Canada, delivered to you weekly.” Constella says eric.malek@rogers.com also had an account at Abusewith[.]us — under the nickname “Jags.

Biderman’s email records show Eric Malek was also a PHP developer for Ashley Madison, and that he was hired into this position just a few months before Bloom — on Sept. 2, 2014. The CEO’s leaked emails show Eric Malek resigned from his developer position at Ashley Madison on June 19, 2015.

“Please note that Eric Malek has resigned from this position with Avid and his last day will be June 19th,” read a June 5, 2015 email from ALM’s HR director. “He is resigning to deal with some personal issues which include health issues. Because he is not sure how much time it will take to resolve, he is not requesting a leave of absence (his time off will be indefinite). Overall, he likes the company and plans to reach out to Trevor or I when the issues are resolved to see what is available at that time.”

A follow-up email from Biderman demanded, “want to know where he’s truly going….,” and it’s unclear whether there was friction with Malek’s departure. But ALM General Counsel Avi Weisman replied indicating that Malek probably would not sign an “Exit Acknowledgment Form” prior to leaving, and that the company had unanswered questions for Malek.

“Aneka should dig during exit interview,” Weisman wrote. “Let’s see if he balks at signing the Acknowledgment.”

Bloom’s departure notice from Ashley Madison’s HR person, dated June 23, 2015, read:

“Please note that Jordan Bloom has resigned from his position as PHP Developer with Avid. He is leaving for personal reasons. He has a neck issue that will require surgery in the upcoming months and because of his medical appointment schedule and the pain he is experiencing he can no longer commit to a full-time schedule. He may pick up contract work until he is back to 100%.”

A follow-up note to Biderman about this announcement read:

“Note that he has disclosed that he is independently wealthy so he can get by without FT work until he is on the mend. He has signed the Exit Acknowledgement Form already without issue. He also says he would consider reapplying to Avid in the future if we have opportunities available at that time.”

Perhaps Mr. Bloom hurt his neck from craning it around blind spots in his Lamborghini. Maybe it was from a bad scuba outing. Whatever the pain in Bloom’s neck was, it didn’t stop him from launching himself fully into LeakedSource[.]com, which was registered roughly one month after the Impact Team leaked data on 37 million Ashley Madison accounts.

Mr. Malek declined a request for comment. A now-deleted LinkedIn profile for Malek from December 2018 listed him as a “technical recruiter” from Toronto who also attended Mr. Bloom’s alma mater — York University. That resume did not mention Mr. Malek’s brief stint as a PHP developer at Ashley Madison.

“Developer, entrepreneur, and now technical recruiter of the most uncommon variety!” Mr. Malek’s LinkedIn profile enthused. “Are you a developer, or other technical specialist, interested in working with a recruiter who can properly understand your concerns and aspirations, technical, environmental and financial? Don’t settle for a ‘hack’; this is your career, let’s do it right! Connect with me on LinkedIn. Note: If you are not a resident of Canada/Toronto, I cannot help you.”

INTERVIEW WITH BLOOM

Mr. Bloom told KrebsOnSecurity he had no role in harming or hacking Ashley Madison. Bloom validated his identity by responding at one of the email addresses mentioned above, and agreed to field questions so long as KrebsOnSecurity agreed to publish our email conversation in full (PDF).

Bloom said Mr. Malek did recommend him for the Ashley Madison job, but that Mr. Malek also received a $5,000 referral bonus for doing so. Given Mr. Malek’s stated role as a technical recruiter, it seems likely he also recommended several other employees to Ashley Madison.

Bloom was asked whether anyone at the RCMP, Ashley Madison or any authority anywhere ever questioned him in connection with the July 2015 hack of Ashley Madison. He replied that he was called once by someone claiming to be from the Toronto Police Service asking if he knew anything about the Ashley Madison hack.

“The AM situation was not something they pursued according to the RCMP disclosure,” Bloom wrote. “Learning about the RCMP’s most advanced cyber investigative techniques and capabilities was very interesting though. I was eventually told information by a third party which included knowledge that law enforcement effectively knew who the hacker was, but didn’t have enough evidence to proceed with a case. That is the extent of my involvement with any authorities.”

As to his company’s guilty plea for operating LeakedSource, Bloom maintains that the judge at his preliminary inquiry found that even if everything the Canadian government alleged was true it would not constitute a violation of any law in Canada with respect the charges the RCMP leveled against him, which included unauthorized use of a computer and “mischief to data.”

“In Canada at the lower court level we are allowed to possess stolen information and manipulate our copies of them as we please,” Bloom said. “The judge however decided that a trial was required to determine whether any activities of mine were reckless, as the other qualifier of intentionally criminal didn’t apply. I will note here that nothing I was accused of doing would have been illegal if done in the United States of America according to their District Attorney. +1 for free speech in America vs freedom of expression in Canada.”

“Shortly after their having most of their case thrown out, the Government proposed an offer during a closed door meeting where they would drop all charges against me, provide full and complete personal immunity, and in exchange the Corporation which has since been dissolved would plead guilty,” Bloom continued. “The Corporation would also pay a modest fine.”

Bloom said he left Ashley Madison because he was bored, but he acknowledged starting LeakedSource partly in response to the Ashley Madison hack.

“I intended to leverage my gaming connections to get into security work including for other private servers such as Minecraft communities and others,” Bloom said. “After months of asking management for more interesting tasks, I became bored. Some days I had virtually nothing to do except spin in my chair so I would browse the source code for security holes to fix because I found it enjoyable.”

“I believe the decision to start LS [LeakedSource] was partly inspired by the AM hack itself, and the large number of people from a former friend group messaging me asking if XYZ person was in the leak after I revealed to them that I downloaded a copy and had the ability to browse it,” Bloom continued. “LS was never my idea – I was just a builder, and the only Canadian. In other countries it was never thought to be illegal on closer examination of their laws.”

Bloom said he still considers himself independently wealthy, and that still has the lime green Lambo. But he said he’s currently unemployed and can’t seem to land a job in what he views as his most promising career path: Information security.

“As I’m sure you’re aware, having negative media attention associated with alleged (key word) criminal activity can have a detrimental effect on employment, banking and relationships,” Bloom wrote. “I have no current interest in being a business owner, nor do I have any useful business ideas to be honest. I was and am interested in interesting Information Security/programming work but it’s too large of a risk for any business to hire someone who was formerly accused of a crime.”

The flaw, tracked as CVE-2023-28121 (CVSS score: 9.8), is a case of authentication bypass that enables unauthenticated attackers to impersonate arbitrary users and perform some actions as the impersonated user, including an

WormGPT: New AI Tool Allows Cybercriminals to Launch Sophisticated Cyber Attacks

By THN
With generative artificial intelligence (AI) becoming all the rage these days, it's perhaps not surprising that the technology has been repurposed by malicious actors to their own advantage, enabling avenues for accelerated cybercrime. According to findings from SlashNext, a new generative AI cybercrime tool called WormGPT has been advertised on underground forums as a way for adversaries to

Apple & Microsoft Patch Tuesday, July 2023 Edition

By BrianKrebs

Microsoft Corp. today released software updates to quash 130 security bugs in its Windows operating systems and related software, including at least five flaws that are already seeing active exploitation. Meanwhile, Apple customers have their own zero-day woes again this month: On Monday, Apple issued (and then quickly pulled) an emergency update to fix a zero-day vulnerability that is being exploited on MacOS and iOS devices.

On July 10, Apple pushed a “Rapid Security Response” update to fix a code execution flaw in the Webkit browser component built into iOS, iPadOS, and macOS Ventura. Almost as soon as the patch went out, Apple pulled the software because it was reportedly causing problems loading certain websites. MacRumors says Apple will likely re-release the patches when the glitches have been addressed.

Launched in May, Apple’s Rapid Security Response updates are designed to address time-sensitive vulnerabilities, and this is the second month Apple has used it. July marks the sixth month this year that Apple has released updates for zero-day vulnerabilities — those that get exploited by malware or malcontents before there is an official patch available.

If you rely on Apple devices and don’t have automatic updates enabled, please take a moment to check the patch status of your various iDevices. The latest security update that includes the fix for the zero-day bug should be available in iOS/iPadOS 16.5.1, macOS 13.4.1, and Safari 16.5.2.

On the Windows side, there are at least four vulnerabilities patched this month that earned high CVSS (badness) scores and that are already being exploited in active attacks, according to Microsoft. They include CVE-2023-32049, which is a hole in Windows SmartScreen that lets malware bypass security warning prompts; and CVE-2023-35311 allows attackers to bypass security features in Microsoft Outlook.

The two other zero-day threats this month for Windows are both privilege escalation flaws. CVE-2023-32046 affects a core Windows component called MSHTML, which is used by Windows and other applications, like Office, Outlook and Skype. CVE-2023-36874 is an elevation of privilege bug in the Windows Error Reporting Service.

Many security experts expected Microsoft to address a fifth zero-day flaw — CVE-2023-36884 — a remote code execution weakness in Office and Windows.

“Surprisingly, there is no patch yet for one of the five zero-day vulnerabilities,” said Adam Barnett, lead software engineer at Rapid7. “Microsoft is actively investigating publicly disclosed vulnerability, and promises to update the advisory as soon as further guidance is available.”

Barnett notes that Microsoft links exploitation of this vulnerability with Storm-0978, the software giant’s name for a cybercriminal group based out of Russia that is identified by the broader security community as RomCom.

“Exploitation of CVE-2023-36884 may lead to installation of the eponymous RomCom trojan or other malware,” Barnett said. “[Microsoft] suggests that RomCom / Storm-0978 is operating in support of Russian intelligence operations. The same threat actor has also been associated with ransomware attacks targeting a wide array of victims.”

Microsoft’s advisory on CVE-2023-36884 is pretty sparse, but it does include a Windows registry hack that should help mitigate attacks on this vulnerability. Microsoft has also published a blog post about phishing campaigns tied to Storm-0978 and to the exploitation of this flaw.

Barnett said it’s while it’s possible that a patch will be issued as part of next month’s Patch Tuesday, Microsoft Office is deployed just about everywhere, and this threat actor is making waves.

“Admins should be ready for an out-of-cycle security update for CVE-2023-36884,” he said.

Microsoft also today released new details about how it plans to address the existential threat of malware that is cryptographically signed by…wait for it….Microsoft.

In late 2022, security experts at Sophos, Trend Micro and Cisco warned that ransomware criminals were using signed, malicious drivers in an attempt to evade antivirus and endpoint detection and response (EDR) tools.

In a blog post today, Sophos’s Andrew Brandt wrote that Sophos identified 133 malicious Windows driver files that were digitally signed since April 2021, and found 100 of those were actually signed by Microsoft. Microsoft said today it is taking steps to ensure those malicious driver files can no longer run on Windows computers.

As KrebsOnSecurity noted in last month’s story on malware signing-as-a-service, code-signing certificates are supposed to help authenticate the identity of software publishers, and provide cryptographic assurance that a signed piece of software has not been altered or tampered with. Both of these qualities make stolen or ill-gotten code-signing certificates attractive to cybercriminal groups, who prize their ability to add stealth and longevity to malicious software.

Dan Goodin at Ars Technica contends that whatever Microsoft may be doing to keep maliciously signed drivers from running on Windows is being bypassed by hackers using open source software that is popular with video game cheaters.

“The software comes in the form of two software tools that are available on GitHub,” Goodin explained. “Cheaters use them to digitally sign malicious system drivers so they can modify video games in ways that give the player an unfair advantage. The drivers clear the considerable hurdle required for the cheat code to run inside the Windows kernel, the fortified layer of the operating system reserved for the most critical and sensitive functions.”

Meanwhile, researchers at Cisco’s Talos security team found multiple Chinese-speaking threat groups have repurposed the tools—one apparently called “HookSignTool” and the other “FuckCertVerifyTimeValidity.”

“Instead of using the kernel access for cheating, the threat actors use it to give their malware capabilities it wouldn’t otherwise have,” Goodin said.

For a closer look at the patches released by Microsoft today, check out the always-thorough Patch Tuesday roundup from the SANS Internet Storm Center. And it’s not a bad idea to hold off updating for a few days until Microsoft works out any kinks in the updates: AskWoody.com usually has the lowdown on any patches that may be causing problems for Windows users.

And as ever, please consider backing up your system or at least your important documents and data before applying system updates. If you encounter any problems with these updates, please drop a note about it here in the comments.
