Man Who Mass-Extorted Psychotherapy Patients Gets Six Years

By BrianKrebs

A 26-year-old Finnish man was sentenced to more than six years in prison today after being convicted of hacking into an online psychotherapy clinic, leaking tens of thousands of patient therapy records, and attempting to extort the clinic and patients.

On October 21, 2020, the Vastaamo Psychotherapy Center in Finland became the target of blackmail when a tormentor identified as “ransom_man” demanded payment of 40 bitcoins (~450,000 euros at the time) in return for a promise not to publish highly sensitive therapy session notes Vastaamo had exposed online.

Ransom_man announced on the dark web that he would start publishing 100 patient profiles every 24 hours. When Vastaamo declined to pay, ransom_man shifted to extorting individual patients. According to Finnish police, some 22,000 victims reported extortion attempts targeting them personally, targeted emails that threatened to publish their therapy notes online unless paid a 500 euro ransom.

Finnish prosecutors quickly zeroed in on a suspect: Julius “Zeekill” Kivimäki, a notorious criminal hacker convicted of committing tens of thousands of cybercrimes before he became an adult. After being charged with the attack in October 2022, Kivimäki fled the country. He was arrested four months later in France, hiding out under an assumed name and passport.

Antti Kurittu is a former criminal investigator who worked on an investigation involving Kivimäki’s use of the Zbot botnet, among other activities Kivimäki engaged in as a member of the hacker group Hack the Planet (HTP).

Kurittu said the prosecution had demanded at least seven years in jail, and that the sentence handed down was six years and three months. Kurittu said prosecutors knocked a few months off of Kivimäki’s sentence because he agreed to pay compensation to his victims, and that Kivimäki will remain in prison during any appeal process.

“I think the sentencing was as expected, knowing the Finnish judicial system,” Kurittu told KrebsOnSecurity. “As Kivimäki has not been sentenced to a non-suspended prison sentence during the last five years, he will be treated as a first-timer, his previous convictions notwithstanding.”

But because juvenile convictions in Finland don’t count towards determining whether somebody is a first-time offender, Kivimäki will end up serving approximately half of his sentence.

“This seems like a short sentence when taking into account the gravity of his actions and the life-altering consequences to thousands of people, but it’s almost the maximum the law allows for,” Kurittu said.

Kivimäki initially gained notoriety as a self-professed member of the Lizard Squad, a mainly low-skilled hacker group that specialized in DDoS attacks. But American and Finnish investigators say Kivimäki’s involvement in cybercrime dates back to at least 2008, when he was introduced to a founding member of what would soon become HTP.

Finnish police said Kivimäki also used the nicknames “Ryan”, “RyanC” and “Ryan Cleary” (Ryan Cleary was actually a member of a rival hacker group — LulzSec — who was sentenced to prison for hacking).

Kivimäki and other HTP members were involved in mass-compromising web servers using known vulnerabilities, and by 2012 Kivimäki’s alias Ryan Cleary was selling access to those servers in the form of a DDoS-for-hire service. Kivimäki was 15 years old at the time.

In 2013, investigators going through devices seized from Kivimäki found computer code that had been used to crack more than 60,000 web servers using a previously unknown vulnerability in Adobe’s ColdFusion software. KrebsOnSecurity detailed the work of HTP in September 2013, after the group compromised servers inside data brokers LexisNexis, Kroll, and Dun & Bradstreet.

The group used the same ColdFusion flaws to break into the National White Collar Crime Center (NWC3), a non-profit that provides research and investigative support to the U.S. Federal Bureau of Investigation (FBI).

As KrebsOnSecurity reported at the time, this small ColdFusion botnet of data broker servers was being controlled by the same cybercriminals who’d assumed control over SSNDOB, which operated one of the underground’s most reliable services for obtaining Social Security Number, dates of birth and credit file information on U.S. residents.

Kivimäki was responsible for making an August 2014 bomb threat against former Sony Online Entertainment President John Smedley that grounded an American Airlines plane. Kivimäki also was involved in calling in multiple fake bomb threats and “swatting” incidents — reporting fake hostage situations at an address to prompt a heavily armed police response to that location.

Ville Tapio, the former CEO of Vastaamo, was fired and also prosecuted following the breach. Ransom_man bragged about Vastaamo’s sloppy security, noting the company had used the laughably weak username and password “root/root” to protect sensitive patient records.

Investigators later found Vastaamo had originally been hacked in 2018 and again in 2019. In April 2023, a Finnish court handed down a three-month sentence for Tapio, but that sentence was suspended because he had no previous criminal record.

Alleged Extortioner of Psychotherapy Patients Faces Trial

By BrianKrebs

Prosecutors in Finland this week commenced their criminal trial against Julius Kivimäki, a 26-year-old Finnish man charged with extorting a once popular and now-bankrupt online psychotherapy practice and thousands of its patients. In a 2,200-page report, Finnish authorities laid out how they connected the extortion spree to Kivimäki, a notorious hacker who was convicted in 2015 of perpetrating tens of thousands of cybercrimes, including data breaches, payment fraud, operating a botnet and calling in bomb threats.

In November 2022, Kivimäki was charged with attempting to extort money from the Vastaamo Psychotherapy Center. In that breach, which occurred in October 2020, a hacker using the handle “Ransom Man” threatened to publish patient psychotherapy notes if Vastaamo did not pay a six-figure ransom demand.

Vastaamo refused, so Ransom Man shifted to extorting individual patients — sending them targeted emails threatening to publish their therapy notes unless paid a 500-euro ransom. When Ransom Man found little success extorting patients directly, they uploaded to the dark web a large compressed file containing all of the stolen Vastaamo patient records.

Security experts soon discovered Ransom Man had mistakenly included an entire copy of their home folder, where investigators found many clues pointing to Kivimäki’s involvement. By that time, Kivimäki was no longer in Finland, but the Finnish government nevertheless charged Kivimäki in absentia with the Vastaamo hack. The 2,200-page evidence document against Kivimäki suggests he enjoyed a lavish lifestyle while on the lam, frequenting luxury resorts and renting fabulously expensive cars and living quarters.

But in February 2023, Kivimäki was arrested in France after authorities there responded to a domestic disturbance call and found the defendant sleeping off a hangover on the couch of a woman he’d met the night before. The French police grew suspicious when the 6′ 3″ blonde, green-eyed man presented an ID that stated he was of Romanian nationality.

A redacted copy of an ID Kivimaki gave to French authorities claiming he was from Romania.

Finnish prosecutors showed that Kivimäki’s credit card had been used to pay for the virtual server that hosted the stolen Vastaamo patient notes. What’s more, the home folder included in the Vastaamo patient data archive also allowed investigators to peer into other cybercrime projects of the accused, including domains that Ransom Man had access to as well as a lengthy history of commands he’d executed on the rented virtual server.

Some of those domains allegedly administered by Kivimäki were set up to smear the reputations of different companies and individuals. One of those was a website that claimed to have been authored by a person who headed up IT infrastructure for a major bank in Norway which discussed the idea of legalizing child sexual abuse.

Another domain hosted a fake blog that besmirched the reputation of a Tulsa, Okla. man whose name was attached to blog posts about supporting the “white pride” movement and calling for a pardon of the Oklahoma City bomber Timothy McVeigh.

Kivimäki appears to have sought to sully the name of this reporter as well. The 2,200-page document shows that Kivimäki owned and operated the domain krebsonsecurity[.]org, which hosted various hacking tools that Kivimäki allegedly used, including programs for mass-scanning the Internet for systems vulnerable to known security flaws, as well as scripts for cracking database server usernames and passwords, and downloading databases.

Ransom Man inadvertently included a copy of his home directory in the leaked Vastaamo patient data. A lengthy history of the commands run by that user show they used krebsonsecurity-dot-org to host hacking and scanning tools.

Mikko Hyppönen, chief research officer at WithSecure (formerly F-Secure), said the Finnish authorities have done “amazing work,” and that “it’s rare to have this much evidence for a cybercrime case.”

Petteri Järvinen is a respected IT expert and author who has been following the trial, and he said the prosecution’s case so far has been strong.

“The National Bureau of Investigation has done a good job and Mr Kivimäki for his part some elementary mistakes,” Järvinen wrote on LinkedIn. “This sends an important message: online crime does not pay. Traces are left in the digital world too, even if it is very tedious for the police to collect them from servers all around the world.”

Antti Kurittu is an information security specialist and a former criminal investigator. In 2013, Kurittu worked on an investigation involving Kivimäki’s use of the Zbot botnet, among other activities Kivimäki engaged in as a member of the hacker group Hack the Planet (HTP). Kurittu said it remains to be seen if the prosecution can make their case, and if the defense has any answers to all of the evidence presented.

“Based on the public pretrial investigation report, it looks like the case has a lot of details that seem very improbable to be coincidental,” Kurittu told KrebsOnSecurity. “For example, a full copy of the Vastaamo patient database was found on a server that belonged to Scanifi, a company with no reasonable business that Kivimäki was affiliated with. The leaked home folder contents were also connected to Kivimäki and were found on servers that were under his control.”

The Finnish daily yle.fi reports that Kivimäki’s lawyers sought to have their client released from confinement for the remainder of his trial, noting that the defendant has already been detained for eight months.

The court denied that request, saying the defendant was still a flight risk. Kivimäki’s trial is expected to continue until February 2024, in part to accommodate testimony from a large number of victims. Prosecutors are seeking a seven-year sentence for Kivimäki.

Microsoft Patch Tuesday, November 2023 Edition

By BrianKrebs

Microsoft today released updates to fix more than five dozen security holes in its Windows operating systems and related software, including three “zero day” vulnerabilities that Microsoft warns are already being exploited in active attacks.

The zero-day threats targeting Microsoft this month include CVE-2023-36025, a weakness that allows malicious content to bypass the Windows SmartScreen Security feature. SmartScreen is a built-in Windows component that tries to detect and block malicious websites and files. Microsoft’s security advisory for this flaw says attackers could exploit it by getting a Windows user to click on a booby-trapped link to a shortcut file.

Kevin Breen, senior director of threat research at Immersive Labs, said emails with .url attachments or logs with processes spawning from .url files “should be a high priority for threat hunters given the active exploitation of this vulnerability in the wild.”

The second zero day this month is CVE-2023-36033, which is a vulnerability in the “DWM Core Library” in Microsoft Windows that was exploited in the wild as a zero day and publicly disclosed prior to patches being available. It affects Microsoft Windows 10 and later, as well as Microsoft Windows Server 2019 and subsequent versions.

“This vulnerability can be exploited locally, with low complexity and without needing high-level privileges or user interaction,” said Mike Walters, president and co-founder of the security firm Action1. “Attackers exploiting this flaw could gain SYSTEM privileges, making it an efficient method for escalating privileges, especially after initial access through methods like phishing.”

The final zero day in this month’s Patch Tuesday is a problem in the “Windows Cloud Files Mini Filter Driver” tracked as CVE-2023-36036 that affects Windows 10 and later, as well as Windows Server 2008 at later. Microsoft says it is relatively straightforward for attackers to exploit CVE-2023-36036 as a way to elevate their privileges on a compromised PC.

Beyond the zero day flaws, Breen said organizations running Microsoft Exchange Server should prioritize several new Exchange patches, including CVE-2023-36439, which is a bug that would allow attackers to install malicious software on an Exchange server. This weakness technically requires the attacker to be authenticated to the target’s local network, but Breen notes that a pair of phished Exchange credentials will provide that access nicely.

“This is typically achieved through social engineering attacks with spear phishing to gain initial access to a host before searching for other vulnerable internal targets – just because your Exchange Server doesn’t have internet-facing authentication doesn’t mean it’s protected,” Breen said.

Breen said this vulnerability goes hand in hand with three other Exchange bugs that Microsoft designated as “exploitation more likely:” CVE-2023-36050, CVE-2023-36039 and CVE-2023-36035.

Finally, the SANS Internet Storm Center points to two additional bugs patched by Microsoft this month that aren’t yet showing signs of active exploitation but that were made public prior to today and thus deserve prioritization. Those include: CVE-2023-36038, a denial of service vulnerability in ASP.NET Core, with a CVSS score of 8.2; and CVE-2023-36413: A Microsoft Office security feature bypass. Exploiting this vulnerability will bypass the protected mode when opening a file received via the web.

Windows users, please consider backing up your data and/or imaging your system before applying any updates. And feel free to sound off in the comments if you experience any difficulties as a result of these patches.

Microsoft Patch Tuesday, May 2023 Edition

By BrianKrebs

Microsoft today released software updates to fix at least four dozen security holes in its Windows operating systems and other software, including patches for two zero-day vulnerabilities that are already being exploited in active attacks.

First up in May’s zero-day flaws is CVE-2023-29336, which is an “elevation of privilege” weakness in Windows which has a low attack complexity, requires low privileges, and no user interaction. However, as the SANS Internet Storm Center points out, the attack vector for this bug is local.

“Local Privilege escalation vulnerabilities are a key part of attackers’ objectives,” said Kevin Breen, director of cyber threat research at Immersive Labs. “Once they gain initial access they will seek administrative or SYSTEM-level permissions. This can allow the attacker to disable security tooling and deploy more attacker tools like Mimikatz that lets them move across the network and gain persistence.”

The zero-day patch that has received the most attention so far is CVE-2023-24932, which is a Secure Boot Security Feature Bypass flaw that is being actively exploited by “bootkit” malware known as “BlackLotus.” A bootkit is dangerous because it allows the attacker to load malicious software before the operating system even starts up.

According to Microsoft’s advisory, an attacker would need physical access or administrative rights to a target device, and could then install an affected boot policy. Microsoft gives this flaw a CVSS score of just 6.7, rating it as “Important.”

Adam Barnett, lead software engineer at Rapid7, said CVE-2023-24932 deserves a considerably higher threat score.

“Microsoft warns that an attacker who already has Administrator access to an unpatched asset could exploit CVE-2023-24932 without necessarily having physical access,” Barnett said. “Therefore, the relatively low CVSSv3 base score of 6.7 isn’t necessarily a reliable metric in this case.”

Barnett said Microsoft has provided a supplementary guidance article specifically calling out the threat posed by BlackLotus malware, which loads ahead of the operating system on compromised assets, and provides attackers with an array of powerful evasion, persistence, and Command & Control (C2) techniques, including deploying malicious kernel drivers, and disabling Microsoft Defender or Bitlocker.

“Administrators should be aware that additional actions are required beyond simply applying the patches,” Barnett advised. “The patch enables the configuration options necessary for protection, but administrators must apply changes to UEFI config after patching. The attack surface is not limited to physical assets, either; Windows assets running on some VMs, including Azure assets with Secure Boot enabled, also require these extra remediation steps for protection. Rapid7 has noted in the past that enabling Secure Boot is a foundational protection against driver-based attacks. Defenders ignore this vulnerability at their peril.”

In addition to the two zero-days fixed this month, Microsoft also patched five remote code execution (RCE) flaws in Windows, two of which have notably high CVSS scores.

CVE-2023-24941 affects the Windows Network File System, and can be exploited over the network by making an unauthenticated, specially crafted request. Microsoft’s advisory also includes mitigation advice. The CVSS for this vulnerability is 9.8 – the highest of all the flaws addressed this month.

Meanwhile, CVE-2023-28283 is a critical bug in the Windows Lightweight Directory Access Protocol (LDAP) that allows an unauthenticated attacker to execute malicious code on the vulnerable device. The CVSS for this vulnerability is 8.1, but Microsoft says exploiting the flaw may be tricky and unreliable for attackers.

Another vulnerability patched this month that was disclosed publicly before today (but not yet seen exploited in the wild) is CVE-2023-29325, a weakness in Microsoft Outlook and Explorer that can be exploited by attackers to remotely install malware. Microsoft says this vulnerability can be exploited merely by viewing a specially-crafted email in the Outlook Preview Pane.

“To help protect against this vulnerability, we recommend users read email messages in plain text format,” Microsoft’s writeup on CVE-2023-29325 advises.

“If an attacker were able to exploit this vulnerability, they would gain remote access to the victim’s account, where they could deploy additional malware,” Immersive’s Breen said. “This kind of exploit will be highly sought after by e-crime and ransomware groups where, if successfully weaponized, could be used to target hundreds of organizations with very little effort.”

For more details on the updates released today, check out roundups by Action1, Automox and Qualys, If today’s updates cause any stability or usability issues in Windows, AskWoody.com will likely have the lowdown on that.

Feds Take Down 13 More DDoS-for-Hire Services

By BrianKrebs

The U.S. Federal Bureau of Investigation (FBI) this week seized 13 domain names connected to “booter” services that let paying customers launch crippling distributed denial-of-service (DDoS) attacks. Ten of the domains are reincarnations of DDoS-for-hire services the FBI seized in December 2022, when it charged six U.S. men with computer crimes for allegedly operating booters.

Booter services are advertised through a variety of methods, including Dark Web forums, chat platforms and even youtube.com. They accept payment via PayPal, Google Wallet, and/or cryptocurrencies, and subscriptions can range in price from just a few dollars to several hundred per month. The services are generally priced according to the volume of traffic to be hurled at the target, the duration of each attack, and the number of concurrent attacks allowed.

The websites that saw their homepages replaced with seizure notices from the FBI this week include booter services like cyberstress[.]org and exoticbooter[.]com, which the feds say were used to launch millions of attacks against millions of victims.

“School districts, universities, financial institutions and government websites are among the victims who have been targeted in attacks launched by booter services,” federal prosecutors in Los Angeles said in a statement.

Purveyors of booters or “stressers” claim they are not responsible for how customers use their services, and that they aren’t breaking the law because — like most security tools — these services can be used for good or bad purposes. Most booter sites employ wordy “terms of use” agreements that require customers to agree they will only stress-test their own networks — and that they won’t use the service to attack others.

But the DOJ says these disclaimers usually ignore the fact that most booter services are heavily reliant on constantly scanning the Internet to commandeer misconfigured devices that are critical for maximizing the size and impact of DDoS attacks. What’s more, none of the services seized by the government required users to demonstrate that they own the Internet addresses being stress-tested, something a legitimate testing service would insist upon.

This is the third in a series of U.S. and international law enforcement actions targeting booter services. In December 2022, the feds seized four-dozen booter domains and charged six U.S. men with computer crimes related to their alleged ownership of the popular DDoS-for-hire services. In December 2018, the feds targeted 15 booter sites, and three booter store defendants who later pleaded guilty.

While the FBI’s repeated seizing of booter domains may seem like an endless game of virtual Whac-a-Mole, continuously taking these services offline imposes high enough costs for the operators that some of them will quit the business altogether, says Richard Clayton, director of Cambridge University’s Cybercrime Centre.

In 2020, Clayton and others published “Cybercrime is Mostly Boring,” an academic study on the quality and types of work needed to build, maintain and defend illicit enterprises that make up a large portion of the cybercrime-as-a-service market. The study found that operating a booter service effectively requires a mind-numbing amount of constant, tedious work that tends to produce high burnout rates for booter service operators — even when the service is operating efficiently and profitably.

For example, running an effective booter service requires a substantial amount of administrative work and maintenance, much of which involves constantly scanning for, commandeering and managing large collections of remote systems that can be used to amplify online attacks, Clayton said. On top of that, building brand recognition and customer loyalty takes time.

“If you’re running a booter and someone keeps taking your domain or hosting away, you have to then go through doing the same boring work all over again,” Clayton told KrebsOnSecurity. “One of the guys the FBI arrested in December [2022] spent six months moaning that he lost his servers, and could people please lend him some money to get it started again.”

In a statement released Wednesday, prosecutors in Los Angeles said four of the six men charged last year for running booter services have since pleaded guilty. However, at least one of the defendants from the 2022 booter bust-up — John M. Dobbs, 32, of Honolulu, HI — has pleaded not guilty and is signaling he intends to take his case to trial.

The FBI seizure notice that replaced the homepages of several booter services this week.

Dobbs is a computer science graduate student who for the past decade openly ran IPStresser[.]com, a popular and powerful attack-for-hire service that he registered with the state of Hawaii using his real name and address. Likewise, the domain was registered in Dobbs’s name and hometown in Pennsylvania. Prosecutors say Dobbs’ service attracted more than two million registered users, and was responsible for launching a staggering 30 million distinct DDoS attacks.

Many accused stresser site operators have pleaded guilty over the years after being hit with federal criminal charges. But the government’s core claim — that operating a booter site is a violation of U.S. computer crime laws — wasn’t properly tested in the courts until September 2021.

That was when a jury handed down a guilty verdict against Matthew Gatrel, a then 32-year-old St. Charles, Ill. man charged in the government’s first 2018 mass booter bust-up. Despite admitting to FBI agents that he ran two booter services (and turning over plenty of incriminating evidence in the process), Gatrel opted to take his case to trial, defended the entire time by court-appointed attorneys.

Gatrel was convicted on all three charges of violating the Computer Fraud and Abuse Act, including conspiracy to commit unauthorized impairment of a protected computer, conspiracy to commit wire fraud, and unauthorized impairment of a protected computer. He was sentenced to two years in prison.

A copy of the FBI’s booter seizure warrant is here (PDF). According to the DOJ, the defendants who pleaded guilty to operating booter sites include:

Jeremiah Sam Evans Miller, aka “John The Dev,” 23, of San Antonio, Texas, who pleaded guilty on April 6 to conspiracy and violating the computer fraud and abuse act related to the operation of a booter service named RoyalStresser[.]com (formerly known as Supremesecurityteam[.]com);

Angel Manuel Colon Jr., aka “Anonghost720” and “Anonghost1337,” 37, of Belleview, Florida, who pleaded guilty on February 13 to conspiracy and violating the computer fraud and abuse act related to the operation of a booter service named SecurityTeam[.]io;

Shamar Shattock, 19, of Margate, Florida, who pleaded guilty on March 22 to conspiracy to violate the computer fraud and abuse act related to the operation of a booter service known as Astrostress[.]com;

Cory Anthony Palmer, 23, of Lauderhill, Florida, who pleaded guilty on February 16 to conspiracy to violate the computer fraud and abuse act related to the operation of a booter service known as Booter[.]sx.

All four defendants are scheduled to be sentenced this summer.

The booter domains seized by the FBI this week include:

Promising Jobs at the U.S. Postal Service, ‘US Job Services’ Leaks Customer Data

By BrianKrebs

A sprawling online company based in Georgia that has made tens of millions of dollars purporting to sell access to jobs at the United States Postal Service (USPS) has exposed its internal IT operations and database of nearly 900,000 customers. The leaked records indicate the network’s chief technology officer in Pakistan has been hacked for the past year, and that the entire operation was created by the principals of a Tennessee-based telemarketing firm that has promoted USPS employment websites since 2016.

The website FederalJobsCenter promises to get you a job at the USPS in 30 days or your money back.

KrebsOnSecurity was recently contacted by a security researcher who said he found a huge tranche of full credit card records exposed online, and that at first glance the domain names involved appeared to be affiliated with the USPS.

Further investigation revealed a long-running international operation that has been emailing and text messaging people for years to sign up at a slew of websites that all promise they can help visitors secure employment at the USPS.

Sites like FederalJobsCenter[.]com also show up prominently in Google search results for USPS employment, and steer applicants toward making credit card “registration deposits” to ensure that one’s application for employment is reviewed. These sites also sell training, supposedly to help ace an interview with USPS human resources.

FederalJobsCenter’s website is full of content that makes it appear the site is affiliated with the USPS, although its “terms and conditions” state that it is not. Rather, the terms state that FederalJobsCenter is affiliated with an entity called US Job Services, which says it is based in Lawrenceville, Ga.

“US Job Services provides guidance, coaching, and live assistance to postal job candidates to help them perform better in each of the steps,” the website explains.

The site says applicants need to make a credit card deposit to register, and that this amount is refundable if the applicant is not offered a USPS job within 30 days after the interview process.

But a review of the public feedback on US Job Services and dozens of similar names connected to this entity over the years shows a pattern of activity: Applicants pay between $39.99 and $100 for USPS job coaching services, and receive little if anything in return. Some reported being charged the same amount monthly.

The U.S. Federal Trade Commission (FTC) has sued several times over the years to disrupt various schemes offering to help people get jobs at the Postal Service. Way back in 1998, the FTC and the USPS took action against several organizations that were selling test or interview preparation services for potential USPS employees.

“Companies promising jobs with the U.S. Postal Service are breaking federal law,” the joint USPS-FTC statement said.

In that 1998 case, the defendants behind the scheme were taking out classified ads in newspapers. Ditto for a case the FTC brought in 2005. By 2008, the USPS job exam preppers had shifted to advertising their schemes mostly online. And in 2013, the FTC won a nearly $5 million judgment against a Kentucky company purporting to offer such services.

Tim McKinlay authored a report last year at Affiliateunguru.com on whether the US Job Services website job-postal[.]com was legitimate or a scam. He concluded it was a scam based on several factors, including that the website listed multiple other names (suggesting it had recently switched names), and that he got nothing from the transaction with the job site.

“They openly admit they’re not affiliated with the US Postal Service, but claim to be experts in the field, and that, just by following the steps on their site, you easily pass the postal exams and get a job in no time,” McKinlay wrote. “But it’s really just a smoke and mirrors game. The site’s true purpose is to collect $46.95 from as many people as possible. And considering how popular this job is, they’re probably making a killing.”

US JOB SERVICES

KrebsOnSecurity was alerted to the data exposure by Patrick Barry, chief information officer at Charlotte, NC based Rebyc Security. Barry said he found that not only was US Job Services leaking its customer payment records in real-time and going back to 2016, but its website also leaked a log file from 2019 containing the site administrator’s contact information and credentials to the site’s back-end database.

Barry shared screenshots of that back-end database, which show the email address for the administrator of US Job Services is tab.webcoder@gmail.com. According to cyber intelligence platform Constella Intelligence, that email address is tied to the LinkedIn profile for a developer in Karachi, Pakistan named Muhammed Tabish Mirza.

A search on tab.webcoder@gmail.com at DomainTools.com reveals that email address was used to register several USPS-themed domains, including postal2017[.]com, postaljobscenter[.]com and usps-jobs[.]com.

Mr. Mirza declined to respond to questions, but the exposed database information was removed from the Internet almost immediately after KrebsOnSecurity shared the offending links.

A “Campaigns” tab on that web panel listed several advertising initiatives tied to US Job Services websites, with names like “walmart drip campaign,” “hiring activity due to virus,” “opt-in job alert SMS,” and “postal job opening.”

Another page on the US Job Services panel included a script for upselling people who call in response to email and text message solicitations, with an add-on program that normally sells for $1,200 but is being “practically given away” for a limited time, for just $49.

An upselling tutorial for call center employees.

“There’s something else we have you can take advantage of that can help you make more money,” the script volunteers. “It’s an easy to use 12-month career development plan and program to follow that will result in you getting any job you want, not just at the post office….anywhere…and then getting promoted rapidly.”

It’s bad enough that US Job Services was leaking customer data: Constella Intelligence says the email address tied to Mr. Mirza shows up in more than a year’s worth of “bot logs” created by a malware infection from the Redline infostealer.

Constella reports that for roughly a year between 2021 and 2022, a Microsoft Windows device regularly used by Mr. Mirza and his colleagues was actively uploading all of the device’s usernames, passwords and authentication cookies to cybercriminals based in Russia.

NEXT LEVEL SUPPORT

The web-based backend for US Job Services lists more than 160 people under its “Users & Teams” tab. This page indicates that access to the consumer and payment data collected by US Job Services is currently granted to several other coders who work with Mr. Mirza in Pakistan, and to multiple executives, contractors and employees working for a call center in Murfreesboro, Tennessee.

The call center — which operates as Nextlevelsupportcenters[.]com and thenextlevelsupport[.]com — curiously has several key associates with a history of registering USPS jobs-related domain names.

The US Job Services website has more than 160 users, including most of the employees at Next Level Support.

The website for NextLevelSupport says it was founded in 2017 by a Gary Plott, whose LinkedIn profile describes him as a seasoned telecommunications industry expert. The leaked backend database for US Job Services says Plott is a current administrator on the system, along with several other Nextlevel founders listed on the company’s site.

Reached via telephone, Plott initially said his company was merely a “white label” call center that multiple clients use to interact with customers, and that the content their call center is responsible for selling on behalf of US Job Services was not produced by NextLevelSupport.

“A few years ago, we started providing support for this postal product,” Plott said. “We didn’t develop the content but agreed we would support it.”

Interestingly, DomainTools says the Gmail address used by Plott in the US Jobs system was also used to register multiple USPS job-related domains, including postaljobssite[.]com, postalwebsite[.]com, usps-nlf[.]com, usps-nla[.]com.

Asked to reconcile this with his previous statement, Plott said he never did anything with those sites but acknowledged that his company did decide to focus on the US Postal jobs market from the very beginning.

Plott said his company never refuses to issue a money-back request from a customer, because doing so would result in costly chargebacks for NextLevel (and presumably for the many credit card merchant accounts apparently set up by Mr. Mirza).

“We’ve never been deceptive,” Plott said, noting that customers of the US Job Services product receive a digital download with tips on how to handle a USPS interview, as well as unlimited free telephone support if they need it.

“We’ve never told anyone we were the US Postal Service,” Plott continued. “We make sure people fully understand that they are not required to buy this product, but we think we can help you and we have testimonials from people we have helped. But ultimately you as the customer make that decision.”

An email address in the US Job Services teams page for another user — Stephanie Dayton — was used to register the domains postalhiringreview[.]com, and postalhiringreviewboard[.]org back in 2014. Reached for comment, Ms. Dayton said she has provided assistance to Next Level Support Centers with their training and advertising, but never in the capacity as an employee.

Perhaps the most central NextLevel associate who had access to US Job Services was Russell Ramage, a telemarketer from Warner Robins, Georgia. Ramage is listed in South Carolina incorporation records as the owner of a now-defunct call center service called Smart Logistics, a company whose name appears in the website registration records for several early and long-running US Job Services sites.

According to the state of Georgia, Russell Ramage was the registered agent of several USPS job-themed companies.

The leaked records show the email address used by Ramage also registered multiple USPS jobs-related domains, including postalhiringcenter[.]com, postalhiringreviews[.]com, postaljobs-email[.]com, and postaljobssupport1[.]com.

A review of business incorporation records in Georgia indicate Ramage was the registered agent for at least three USPS-related companies over the years, including Postal Career Placement LLC, Postal Job Services Inc., and Postal Operations Inc. All three companies were founded in 2015, and are now dissolved.

An obituary dated February 2023 says Russell Ramage recently passed away at the age of 41. No cause of death was stated, but the obituary goes on to say that Russ “Rusty” Ramage was “preceded in death by his mother, Anita Lord Ramage, pets, Raine and Nola and close friends, Nicole Reeves and Ryan Rawls.”

In 2014, then 33-year-old Ryan “Jootgater” Rawls of Alpharetta, Georgia pleaded guilty to conspiring to distribute controlled substances. Rawls also grew up in Warner Robins, and was one of eight suspects charged with operating a secret darknet narcotics ring called the Farmer’s Market, which federal prosecutors said trafficked in millions of dollars worth of controlled substances.

Reuters reported that an eighth suspect in that case had died by the time of Rawls’ 2014 guilty plea, although prosecutors declined to offer further details about that. According to his obituary, Ryan Christopher Rawls died at the age of 38 on Jan. 28, 2019.

In a comment on Ramage’s memorial wall, Stephanie Dayton said she began working with Ramage in 2006.

“Our friendship far surpassed a working one, we had a very close bond and became like brother and sister,” Dayton wrote. “I loved Russ deeply and he was like family. He was truly one of the best human beings I have ever known. He was kind and sweet and truly cared about others. Never met anyone like him. He will be truly missed. RIP brother.”

The FTC and USPS note that while applicants for many entry-level postal jobs are required to take a free postal exam, the tests are usually offered only every few years in any particular district, and there are no job placement guarantees based on score.

“If applicants pass the test by scoring at least 70 out of 100, they are placed on a register, ranked by their score,” the FTC explained. “When a position becomes open, the local post office looks to the applicable register for that geographic location and calls the top three applicants. The score is only one of many criteria taken into account for employment. The exams test general aptitude, something that cannot necessarily be increased by studying.”

The FTC says anyone interested in a job at the USPS should inquire at their local postal office, where applicants generally receive a free packet of information about required exams. More information about job opportunities at the postal service is available at the USPS’s careers website.

Michael Martel, spokesperson for the United States Postal Inspection Service, said in a written statement that the USPS has no affiliation with the websites or companies named in this story.

“To learn more about employment with USPS, visit USPS.com/careers,” Martel wrote. “If you are the victim of a crime online report it to the FBI’s Internet Crime Complaint Center (IC3) at www.ic3.gov. To report fraud committed through or toward the USPS, its employees, or customers, report it to the United States Postal Inspection Service (USPIS) at www.uspis.gov/report.”

Why You Should Opt Out of Sharing Data With Your Mobile Provider

By BrianKrebs

A new breach involving data from nine million AT&T customers is a fresh reminder that your mobile provider likely collects and shares a great deal of information about where you go and what you do with your mobile device — unless and until you affirmatively opt out of this data collection. Here’s a primer on why you might want to do that, and how.

Telecommunications giant AT&T disclosed this month that a breach at a marketing vendor exposed certain account information for nine million customers. AT&T said the data exposed did not include sensitive information, such as credit card or Social Security numbers, or account passwords, but was limited to “Customer Proprietary Network Information” (CPNI), such as the number of lines on an account.

Certain questions may be coming to mind right now, like “What the heck is CPNI?” And, ‘If it’s so ‘customer proprietary,’ why is AT&T sharing it with marketers?” Also maybe, “What can I do about it?” Read on for answers to all three questions.

AT&T’s disclosure said the information exposed included customer first name, wireless account number, wireless phone number and email address. In addition, a small percentage of customer records also exposed the rate plan name, past due amounts, monthly payment amounts and minutes used.

CPNI refers to customer-specific “metadata” about the account and account usage, and may include:

-Called phone numbers
-Time of calls
-Length of calls
-Cost and billing of calls
-Service features
-Premium services, such as directory call assistance

According to a succinct CPNI explainer at TechTarget, CPNI is private and protected information that cannot be used for advertising or marketing directly.

“An individual’s CPNI can be shared with other telecommunications providers for network operating reasons,” wrote TechTarget’s Gavin Wright. “So, when the individual first signs up for phone service, this information is automatically shared by the phone provider to partner companies.”

Is your mobile Internet usage covered by CPNI laws? That’s less clear, as the CPNI rules were established before mobile phones and wireless Internet access were common. TechTarget’s CPNI primer explains:

“Under current U.S. law, cellphone use is only protected as CPNI when it is being used as a telephone. During this time, the company is acting as a telecommunications provider requiring CPNI rules. Internet use, websites visited, search history or apps used are not protected CPNI because the company is acting as an information services provider not subject to these laws.”

Hence, the carriers can share and sell this data because they’re not explicitly prohibited from doing so. All three major carriers say they take steps to anonymize the customer data they share, but researchers have shown it is not terribly difficult to de-anonymize supposedly anonymous web-browsing data.

“Your phone, and consequently your mobile provider, know a lot about you,” wrote Jack Morse for Mashable. “The places you go, apps you use, and the websites you visit potentially reveal all kinds of private information — e.g. religious beliefs, health conditions, travel plans, income level, and specific tastes in pornography. This should bother you.”

Happily, all of the U.S. carriers are required to offer customers ways to opt out of having data about how they use their devices shared with marketers. Here’s a look at some of the carrier-specific practices and opt-out options.

AT&T

AT&T’s policy says it shares device or “ad ID”, combined with demographics including age range, gender, and ZIP code information with third parties which explicitly include advertisers, programmers, and networks, social media networks, analytics firms, ad networks and other similar companies that are involved in creating and delivering advertisements.

AT&T said the data exposed on 9 million customers was several years old, and mostly related to device upgrade eligibility. This may sound like the data went to just one of its partners who experienced a breach, but in all likelihood it also went to hundreds of AT&T’s partners.

AT&T’s CPNI opt-out page says it shares CPNI data with several of its affiliates, including WarnerMedia, DirecTV and Cricket Wireless. Until recently, AT&T also shared CPNI data with Xandr, whose privacy policy in turn explains that it shares data with hundreds of other advertising firms. Microsoft bought Xandr from AT&T last year.

T-MOBILE

According to the Electronic Privacy Information Center (EPIC), T-Mobile seems to be the only company out of the big three to extend to all customers the rights conferred by the California Consumer Privacy Act (CCPA).

EPIC says T-Mobile customer data sold to third parties uses another unique identifier called mobile advertising IDs or “MAIDs.” T-Mobile claims that MAIDs don’t directly identify consumers, but under the CCPA MAIDs are considered “personal information” that can be connected to IP addresses, mobile apps installed or used with the device, any video or content viewing information, and device activity and attributes.

T-Mobile customers can opt out by logging into their account and navigating to the profile page, then to “Privacy and Notifications.” From there, toggle off the options for “Use my data for analytics and reporting” and “Use my data to make ads more relevant to me.”

VERIZON

Verizon’s privacy policy says it does not sell information that personally identities customers (e.g., name, telephone number or email address), but it does allow third-party advertising companies to collect information about activity on Verizon websites and in Verizon apps, through MAIDs, pixels, web beacons and social network plugins.

According to Wired.com’s tutorial, Verizon users can opt out by logging into their Verizon account through a web browser or the My Verizon mobile app. From there, select the Account tab, then click Account Settings and Privacy Settings on the web. For the mobile app, click the gear icon in the upper right corner and then Manage Privacy Settings.

On the privacy preferences page, web users can choose “Don’t use” under the Custom Experience section. On the My Verizon app, toggle any green sliders to the left.

EPIC notes that all three major carriers say resetting the consumer’s device ID and/or clearing cookies in the browser will similarly reset any opt-out preferences (i.e., the customer will need to opt out again), and that blocking cookies by default may also block the opt-out cookie from being set.

T-Mobile says its opt out is device-specific and/or browser-specific. “In most cases, your opt-out choice will apply only to the specific device or browser on which it was made. You may need to separately opt out from your other devices and browsers.”

Both AT&T and Verizon offer opt-in programs that gather and share far more information, including device location, the phone numbers you call, and which sites you visit using your mobile and/or home Internet connection. AT&T calls this their Enhanced Relevant Advertising Program; Verizon’s is called Custom Experience Plus.

In 2021, multiple media outlets reported that some Verizon customers were being automatically enrolled in Custom Experience Plus — even after those customers had already opted out of the same program under its previous name — “Verizon Selects.”

If none of the above opt out options work for you, at a minimum you should be able to opt out of CPNI sharing by calling your carrier, or by visiting one of their stores.

THE CASE FOR OPTING OUT

Why should you opt out of sharing CPNI data? For starters, some of the nation’s largest wireless carriers don’t have a great track record in terms of protecting the sensitive information that you give them solely for the purposes of becoming a customer — let alone the information they collect about your use of their services after that point.

In January 2023, T-Mobile disclosed that someone stole data on 37 million customer accounts, including customer name, billing address, email, phone number, date of birth, T-Mobile account number and plan details. In August 2021, T-Mobile acknowledged that hackers made off with the names, dates of birth, Social Security numbers and driver’s license/ID information on more than 40 million current, former or prospective customers who applied for credit with the company.

Last summer, a cybercriminal began selling the names, email addresses, phone numbers, SSNs and dates of birth on 23 million Americans. An exhaustive analysis of the data strongly suggested it all belonged to customers of one AT&T company or another. AT&T stopped short of saying the data wasn’t theirs, but said the records did not appear to have come from its systems and may be tied to a previous data incident at another company.

However frequently the carriers may alert consumers about CPNI breaches, it’s probably nowhere near often enough. Currently, the carriers are required to report a consumer CPNI breach only in cases “when a person, without authorization or exceeding authorization, has intentionally gained access to, used or disclosed CPNI.”

But that definition of breach was crafted eons ago, back when the primary way CPNI was exposed was through “pretexting,” such when the phone company’s employees are tricked into giving away protected customer data.

In January, regulators at the U.S. Federal Communications Commission (FCC) proposed amending the definition of “breach” to include things like inadvertent disclosure — such as when companies expose CPNI data on a poorly-secured server in the cloud. The FCC is accepting public comments on the matter until March 24, 2023.

While it’s true that the leak of CPNI data does not involve sensitive information like Social Security or credit card numbers, one thing AT&T’s breach notice doesn’t mention is that CPNI data — such as balances and payments made — can be abused by fraudsters to make scam emails and text messages more believable when they’re trying to impersonate AT&T and phish AT&T customers.

The other problem with letting companies share or sell your CPNI data is that the wireless carriers can change their privacy policies at any time, and you are assumed to be okay with those changes as long as you keep using their services.

For example, location data from your wireless device is most definitely CPNI, and yet until very recently all of the major carriers sold their customers’ real-time location data to third party data brokers without customer consent.

What was their punishment? In 2020, the FCC proposed fines totaling $208 million against all of the major carriers for selling their customers’ real-time location data. If that sounds like a lot of money, consider that all of the major wireless providers reported tens of billions of dollars in revenue last year (e.g., Verizon’s consumer revenue alone was more than $100 billion last year).

If the United States had federal privacy laws that were at all consumer-friendly and relevant to today’s digital economy, this kind of data collection and sharing would always be opt-in by default. In such a world, the enormously profitable wireless industry would likely be forced to offer clear financial incentives to customers who choose to share this information.

But until that day arrives, understand that the carriers can change their data collection and sharing policies when it suits them. And regardless of whether you actually read any notices about changes to their privacy policies, you will have agreed to those changes as long as you continue using their service.

Microsoft Patch Tuesday, February 2023 Edition

By BrianKrebs

Microsoft is sending the world a whole bunch of love today, in the form of patches to plug dozens of security holes in its Windows operating systems and other software. This year’s special Valentine’s Day Patch Tuesday includes fixes for a whopping three different “zero-day” vulnerabilities that are already being used in active attacks.

Microsoft’s security advisories are somewhat sparse with details about the zero-day bugs. Redmond flags CVE-2023-23376 as an “Important” elevation of privilege vulnerability in the Windows Common Log File System Driver, which is present in Windows 10 and 11 systems, as well as many server versions of Windows.

“Sadly, there’s just a little solid information about this privilege escalation,” said Dustin Childs, head of threat awareness at Trend Micro’s Zero Day Initiative. “Microsoft does note that the vulnerability would allow an attacker to exploit code as SYSTEM, which would allow them to completely take over a target. This is likely being chained with a remote code execution bug to spread malware or ransomware. Considering this was discovered by Microsoft’s Threat Intelligence Center, it could mean it was used by advanced threat actors. Either way, make sure you test and roll these fixes quickly.”

The zero-day CVE-2023-21715 is a weakness in Microsoft Office that Redmond describes as a “security feature bypass vulnerability.”

“Microsoft lists this as under active exploit, but they offer no info on how widespread these exploits may be,” Childs said. “Based on the write-up, it sounds more like a privilege escalation than a security feature bypass, but regardless, active attacks in a common enterprise application shouldn’t be ignored. It’s always alarming when a security feature is not just bypassed but exploited. Let’s hope the fix comprehensively addresses the problem.”

The third zero-day flaw already seeing exploitation is CVE-2023-21823, which is another elevation of privilege weakness — this one in the Microsoft Windows Graphic component. Researchers at cybersecurity forensics firm Mandiant were credited with reporting the bug.

Kevin Breen, director of cyber threat research at Immersive Labs, pointed out that the security bulletin for CVE-2023-21823 specifically calls out OneNote as being a vulnerable component for the vulnerability.

“In recent weeks, we have seen an increase in the use of OneNote files as part of targeted malware campaigns,” Breen said. “Patches for this are delivered via the app stores and not through the typical formats, so it’s important to double check your organization’s policies.”

Microsoft fixed another Office vulnerability in CVE-2023-21716, which is a Microsoft Word bug that can lead to remote code execution — even if a booby-trapped Word document is merely viewed in the preview pane of Microsoft Outlook. This security hole has a CVSS (severity) score of 9.8 out of a possible 10.

Microsoft also has more valentines for organizations that rely on Microsoft Exchange Server to handle email. Redmond patched three Exchange Server flaws (CVE-2023-21706, CVE-2023-21707, and CVE-2023-21529), all of which Microsoft says are remote code execution flaws that are likely to be exploited.

Microsoft said authentication is required to exploit these bugs, but then again threat groups that attack Exchange vulnerabilities also tend to phish targets for their Exchange credentials.

Microsoft isn’t alone in dropping fixes for scary, ill-described zero-day flaws. Apple on Feb. 13 released an update for iOS that resolves a zero-day vulnerability in Webkit, Apple’s open source browser engine. Johannes Ullrich at the SANS Internet Storm Center notes that in addition to the WebKit problem, Apple fixed a privilege escalation issue. Both flaws are fixed in iOS 16.3.1.

“This privilege escalation issue could be used to escape the browser sandbox and gain full system access after executing code via the WebKit vulnerability,” Ullrich warned.

On a lighter note (hopefully), Microsoft drove the final nail in the coffin for Internet Explorer 11 (IE11). According to Redmond, the out-of-support IE11 desktop application was permanently disabled on certain versions of Windows 10 on February 14, 2023 through a Microsoft Edge update.

“All remaining consumer and commercial devices that were not already redirected from IE11 to Microsoft Edge were redirected with the Microsoft Edge update. Users will be unable to reverse the change,” Microsoft explained. “Additionally, redirection from IE11 to Microsoft Edge will be included as part of all future Microsoft Edge updates. IE11 visual references, such as the IE11 icons on the Start Menu and taskbar, will be removed by the June 2023 Windows security update (“B” release) scheduled for June 13, 2023.”

For a more granular rundown on the updates released today, see the SANS Internet Storm Center roundup. If today’s updates cause any stability or usability issues in Windows, AskWoody.com will likely have the lowdown on that.

Please consider backing up your data and/or imaging your system before applying any updates. And feel free to sound off in the comments if you experience any problems as a result of these patches.

Finland’s Most-Wanted Hacker Nabbed in France

By BrianKrebs

Julius “Zeekill” Kivimäki, a 25-year-old Finnish man charged with extorting a local online psychotherapy practice and leaking therapy notes for more than 22,000 patients online, was arrested this week in France. A notorious hacker convicted of perpetrating tens of thousands of cybercrimes, Kivimäki had been in hiding since October 2022, when he failed to show up in court and Finland issued an international warrant for his arrest.

In late October 2022, Kivimäki was charged (and “arrested in absentia,” according to the Finns) with attempting to extort money from the Vastaamo Psychotherapy Center. In that breach, which occurred in October 2020, a hacker using the handle “Ransom Man” threatened to publish patient psychotherapy notes if Vastaamo did not pay a six-figure ransom demand.

Vastaamo refused, so Ransom Man shifted to extorting individual patients — sending them targeted emails threatening to publish their therapy notes unless paid a 500-euro ransom.

When Ransom Man found little success extorting patients directly, they uploaded to the dark web a large compressed file containing all of the stolen Vastaamo patient records.

But as documented by KrebsOnSecurity in November 2022, security experts soon discovered Ransom Man had mistakenly included an entire copy of their home folder, where investigators found many clues pointing to Kivimäki’s involvement. From that story:

“Among those who grabbed a copy of the database was Antti Kurittu, a team lead at Nixu Corporation and a former criminal investigator. In 2013, Kurittu worked on an investigation involving Kivimäki’s use of the Zbot botnet, among other activities Kivimäki engaged in as a member of the hacker group Hack the Planet (HTP).”

“It was a huge opsec [operational security] fail, because they had a lot of stuff in there — including the user’s private SSH folder, and a lot of known hosts that we could take a very good look at,” Kurittu told KrebsOnSecurity, declining to discuss specifics of the evidence investigators seized. “There were also other projects and databases.”

According to the French news site actu.fr, Kivimäki was arrested around 7 a.m. on Feb. 3, after authorities in Courbevoie responded to a domestic violence report. Kivimäki had been out earlier with a woman at a local nightclub, and later the two returned to her home but reportedly got into a heated argument.

Police responding to the scene were admitted by another woman — possibly a roommate — and found the man inside still sleeping off a long night. When they roused him and asked for identification, the 6′ 3″ blonde, green-eyed man presented an ID that stated he was of Romanian nationality.

The French police were doubtful. After consulting records on most-wanted criminals, they quickly identified the man as Kivimäki and took him into custody.

Kivimäki initially gained notoriety as a self-professed member of the Lizard Squad, a mainly low-skilled hacker group that specialized in DDoS attacks. But American and Finnish investigators say Kivimäki’s involvement in cybercrime dates back to at least 2008, when he was introduced to a founding member of what would soon become HTP.

Finnish police said Kivimäki also used the nicknames “Ryan”, “RyanC” and “Ryan Cleary” (Ryan Cleary was actually a member of a rival hacker group — LulzSec — who was sentenced to prison for hacking).

Kivimaki and other HTP members were involved in mass-compromising web servers using known vulnerabilities, and by 2012 Kivimäki’s alias Ryan Cleary was selling access to those servers in the form of a DDoS-for-hire service. Kivimäki was 15 years old at the time.

The DDoS-for-hire service allegedly operated by Kivimäki in 2012.

In 2013, investigators going through devices seized from Kivimäki found computer code that had been used to crack more than 60,000 web servers using a previously unknown vulnerability in Adobe’s ColdFusion software.

KrebsOnSecurity detailed the work of HTP in September 2013, after the group compromised servers inside data brokers LexisNexis, Kroll, and Dun & Bradstreet.

The group used the same ColdFusion flaws to break into the National White Collar Crime Center (NWC3), a non-profit that provides research and investigative support to the U.S. Federal Bureau of Investigation (FBI).

As KrebsOnSecurity reported at the time, this small ColdFusion botnet of data broker servers was being controlled by the same cybercriminals who’d assumed control over ssndob[.]ms, which operated one of the underground’s most reliable services for obtaining Social Security Number, dates of birth and credit file information on U.S. residents.

Multiple law enforcement sources told KrebsOnSecurity that Kivimäki was responsible for making an August 2014 bomb threat against former Sony Online Entertainment President John Smedley that grounded an American Airlines plane. That incident was widely reported to have started with a tweet from the Lizard Squad, but Smedley and others said it started with a call from Kivimäki.

Kivimäki also was involved in calling in multiple fake bomb threats and “swatting” incidents — reporting fake hostage situations at an address to prompt a heavily armed police response to that location.

Kivimäki’s apparent indifference to hiding his tracks drew the interest of Finnish and American cybercrime investigators, and soon Finnish prosecutors charged him with an array of cybercrime violations. At trial, prosecutors presented evidence showing he’d used stolen credit cards to buy luxury goods and shop vouchers, and participated in a money laundering scheme that he used to fund a trip to Mexico.

Kivimäki was ultimately convicted of orchestrating more than 50,000 cybercrimes. But largely because he was still a minor at the time (17) , he was given a 2-year suspended sentence and ordered to forfeit EUR 6,558.

As I wrote in 2015 following Kivimäki’s trial:

“The danger in such a decision is that it emboldens young malicious hackers by reinforcing the already popular notion that there are no consequences for cybercrimes committed by individuals under the age of 18.

Kivimäki is now crowing about the sentence; He’s changed the description on his Twitter profile to “Untouchable hacker god.” The Twitter account for the Lizard Squad tweeted the news of Kivimäki’s non-sentencing triumphantly: “All the people that said we would rot in prison don’t want to comprehend what we’ve been saying since the beginning, we have free passes.”

Something tells me Kivimäki won’t get off so easily this time, assuming he is successfully extradited back to Finland. A statement by the Finnish police says they are seeking Kivimäki’s extradition and that they expect the process to go smoothly.

Kivimäki could not be reached for comment. But he has been discussing his case on Reddit using his legal first name — Aleksanteri (he stopped using his middle name Julius when he moved abroad several years ago). In a post dated Jan. 31, 2022, Kivimäki responded to another Finnish-speaking Reddit user who said they were a fugitive from justice.

“Same thing,” Kivimäki replied. “Shall we start some kind of club? A support organization for wanted persons?”

The Equifax Breach Settlement Offer is Real, For Now

By BrianKrebs

Millions of people likely just received an email or snail mail notice saying they’re eligible to claim a class action payment in connection with the 2017 megabreach at consumer credit bureau Equifax. Given the high volume of reader inquiries about this, it seemed worth pointing out that while this particular offer is legit (if paltry), scammers are likely to soon capitalize on public attention to the settlement money.

One reader’s copy of their Equifax Breach Settlement letter. They received a check for $6.97.

In 2017, Equifax disclosed a massive, extended data breach that led to the theft of Social Security Numbers, dates of birth, addresses and other personal information on nearly 150 million people. Following a public breach response perhaps best described as a giant dumpster fire, the big-three consumer credit reporting bureau was quickly hit with nearly two dozen class-action lawsuits.

In exchange for resolving all outstanding class action claims against it, Equifax in 2019 agreed to a settlement that includes up to $425 million to help people affected by the breach.

Affected consumers were eligible to apply for at least three years of credit monitoring via all three major bureaus simultaneously, including Equifax, Experian and TransUnion. Or, if you didn’t want to take advantage of the credit monitoring offers, you could opt for a cash payment of up to $125.

The settlement also offered reimbursement for the time you may have spent remedying identity theft or misuse of your personal information caused by the breach, or purchasing credit monitoring or credit reports. This was capped at 20 total hours at $25 per hour ($500), with total cash reimbursement payments not to exceed $20,000 per consumer.

Those who did file a claim probably started receiving emails or other communications earlier this year from the Equifax Breach Settlement Fund, which has been messaging class participants about methods of collecting their payments.

How much each recipient receives appears to vary quite a bit, but probably most people will have earned a payment on the smaller end of that $125 scale — like less than $10. Those who received higher amounts likely spent more time documenting actual losses and/or explaining how the breach affected them personally.

So far this week, KrebsOnSecurity has received at least 20 messages from readers seeking more information about these notices. Some readers shared copies of letters they got in the mail along with a paper check from the Equifax Breach Settlement Fund (see screenshot above).

Others said they got emails from the Equifax Breach Settlement domain that looked like an animated greeting card offering instructions on how to redeem a virtual prepaid card.

If you received one of these settlement emails and are wary about clicking the included links (good for you, by the way), copy the redemption code and paste it into the search box at myprepaidcenter.com/redeem. Successfully completing the card application requires accepting a prepaid MasterCard agreement (PDF).

The website for the settlement — equifaxbreachsettlement.com — also includes a lookup tool that lets visitors check whether they were affected by the breach; it requires your last name and the last six digits of your Social Security Number.

But be aware that phishers and other scammers are likely to take advantage of increased public awareness of the payouts to snooker people. Tim Helming, security evangelist at DomainTools.com, today flagged several new domains that mimic the name of the real Equifax Breach Settlement website and do not appear to be defensively registered by Equifax, including equifaxbreechsettlement[.]com, equifaxbreachsettlementbreach[.]com, and equifaxsettlements[.]co.

In February 2020, the U.S. Justice Department indicted four Chinese officers of the People’s Liberation Army (PLA) for perpetrating the 2017 Equifax hack. DOJ officials said the four men were responsible for carrying out the largest theft of sensitive personal information by state-sponsored hackers ever recorded.

Equifax surpassed Wall Street’s expectations in its most recent quarterly earnings: The company reported revenues of $1.24 billion for the quarter ending September 2022.

Of course, most of those earnings come from Equifax’s continued legal ability to buy and sell eye-popping amounts of financial and personal data on U.S. consumers. As one of the three major credit bureaus, Equifax collects and packages information about your credit, salary, and employment history. It tracks how many credit cards you have, how much money you owe, and how you pay your bills. Each company creates a credit report about you, and then sells this report to businesses who are deciding whether to give you credit.

Americans currently have no legal right to opt out of this data collection and trade. But you can and also should freeze your credit, which by the way can make your credit profile less profitable for companies like Equifax — because they make money every time some potential creditor wants a peek inside your financial life. Also, it’s probably a good idea to freeze the credit of your children and/or dependents as well. It’s free on both counts.

U.S. Govt. Apps Bundled Russian Code With Ties to Mobile Malware Developer

A recent scoop by Reuters revealed that mobile apps for the U.S. Army and the Centers for Disease Control and Prevention (CDC) were integrating software that sends visitor data to a Russian company called Pushwoosh, which claims to be based in the United States. But that story omitted an important historical detail about Pushwoosh: In 2013, one of its developers admitted to authoring the Pincer Trojan, malware designed to surreptitiously intercept and forward text messages from Android mobile devices.

Pushwoosh says it is a U.S. based company that provides code for software developers to profile smartphone app users based on their online activity, allowing them to send tailor-made notifications. But a recent investigation by Reuters raised questions about the company’s real location and truthfulness.

The Army told Reuters it removed an app containing Pushwoosh in March, citing “security concerns.” The Army app was used by soldiers at one of the nation’s main combat training bases.

Reuters said the CDC likewise recently removed Pushwoosh code from its app over security concerns, after reporters informed the agency Pushwoosh was not based in the Washington D.C. area — as the company had represented — but was instead operated from Novosibirsk, Russia.

Pushwoosh’s software also was found in apps for “a wide array of international companies, influential nonprofits and government agencies from global consumer goods company Unilever and the Union of European Football Associations (UEFA) to the politically powerful U.S. gun lobby, the National Rifle Association (NRA), and Britain’s Labour Party.”

The company’s founder Max Konev told Reuters Pushwoosh “has no connection with the Russian government of any kind” and that it stores its data in the United States and Germany.

But Reuters found that while Pushwoosh’s social media and U.S. regulatory filings present it as a U.S. company based variously in California, Maryland and Washington, D.C., the company’s employees are located in Novosibirsk, Russia.

Reuters also learned that the company’s address in California does not exist, and that two LinkedIn accounts for Pushwoosh employees in Washington, D.C. were fake.

“Pushwoosh never mentioned it was Russian-based in eight annual filings in the U.S. state of Delaware, where it is registered, an omission which could violate state law,” Reuters reported.

Pushwoosh admitted the LinkedIn profiles were fake, but said they were created by a marketing firm to drum up business for the company — not misrepresent its location.

Pushwoosh told Reuters it used addresses in the Washington, D.C. area to “receive business correspondence” during the coronavirus pandemic. A review of the Pushwoosh founder’s online presence via Constella Intelligence shows his Pushwoosh email address was tied to a phone number in Washington, D.C. that was also connected to email addresses and account profiles for over a dozen other Pushwoosh employees.

Pushwoosh was incorporated in Novosibirsk, Russia in 2016.

THE PINCER TROJAN CONNECTION

The dust-up over Pushwoosh came in part from data gathered by Zach Edwards, a security researcher who until recently worked for the Internet Safety Labs, a nonprofit organization that funds research into online threats.

Edwards said Pushwoosh began as Arello-Mobile, and for several years the two co-branded — appearing side by side at various technology expos. Around 2016, he said, the two companies both started using the Pushwoosh name.

A search on Pushwoosh’s code base shows that one of the company’s longtime developers is a 41-year-old from Novosibirsk named Yuri Shmakov. In 2013, KrebsOnSecurity interviewed Shmakov for the story, “Who Wrote the Pincer Android Trojan?” wherein Shmakov acknowledged writing the malware as a freelance project.

Shmakov told me that, based on the client’s specifications, he suspected it might ultimately be put to nefarious uses. Even so, he completed the job and signed his work by including his nickname in the app’s code.

“I was working on this app for some months, and I was hoping that it would be really helpful,” Shmakov wrote. “[The] idea of this app is that you can set it up as a spam filter…block some calls and SMS remotely, from a Web service. I hoped that this will be [some kind of] blacklist, with logging about blocked [messages/calls]. But of course, I understood that client [did] not really want this.”

Shmakov did not respond to requests for comment. His LinkedIn profile says he stopped working for Arello Mobile in 2016, and that he currently is employed full-time as the Android team leader at an online betting company.

In a blog post responding to the Reuters story, Pushwoosh said it is a privately held company incorporated under the state laws of Delaware, USA, and that Pushwoosh Inc. was never owned by any company registered in the Russian Federation.

“Pushwoosh Inc. used to outsource development parts of the product to the Russian company in Novosibirsk, mentioned in the article,” the company said. “However, in February 2022, Pushwoosh Inc. terminated the contract.”

However, Edwards noted that dozens of developer subdomains on Pushwoosh’s main domain still point to JSC Avantel, an Internet provider based in Novosibirsk, Russia.

WAR GAMES

Edwards said the U.S. Army’s app had a custom Pushwoosh configuration that did not appear on any other customer implementation.

“It had an extremely custom setup that existed nowhere else,” Edwards said. “Originally, it was an in-app Web browser, where it integrated a Pushwoosh javascript so that any time a user clicked on links, data went out to Pushwoosh and they could push back whatever they wanted through the in-app browser.”

An Army Times article published the day after the Reuters story ran said at least 1,000 people downloaded the app, which “delivered updates for troops at the National Training Center on Fort Irwin, Calif., a critical waypoint for deploying units to test their battlefield prowess before heading overseas.”

In April 2022, roughly 4,500 Army personnel converged on the National Training Center for a war games exercise on how to use lessons learned from Russia’s war against Ukraine to prepare for future fights against a major adversary such as Russia or China.

Edwards said despite Pushwoosh’s many prevarications, the company’s software doesn’t appear to have done anything untoward to its customers or users.

“Nothing they did has been seen to be malicious,” he said. “Other than completely lying about where they are, where their data is being hosted, and where they have infrastructure.”

GOV 311

Edwards also found Pushwoosh’s technology embedded in nearly two dozen mobile apps that were sold to cities and towns across Illinois as a way to help citizens access general information about their local communities and officials.

The Illinois apps that bundled Pushwoosh’s technology were produced by a company called Government 311, which is owned by Bill McCarty, the current director of the Springfield Office of Budget and Management. A 2014 story in The State Journal-Register said Gov 311’s pricing was based on population, and that the app would cost around $2,500 per year for a city with approximately 25,000 people.

McCarty told KrebsOnSecurity that his company stopped using Pushwoosh “years ago,” and that it now relies on its own technology to provide push notifications through its 311 apps.

But Edwards found some of the 311 apps still try to phone home to Pushwoosh, such as the 311 app for Riverton, Ill.

“Riverton ceased being a client several years ago, which [is] probably why their app was never updated to change out Pushwoosh,” McCarty explained. “We are in the process of updating all client apps and a website refresh. As part of that, old unused apps like Riverton 311 will be deleted.”

FOREIGN ADTECH THREAT?

Edwards said it’s far from clear how many other state and local government apps and Web sites rely on technology that sends user data to U.S. adversaries overseas. In July, Congress introduced an amended version of the Intelligence Authorization Act for 2023, which included a new section focusing on data drawn from online ad auctions that could be used to geolocate individuals or gain other information about them.

Business Insider reports that if this section makes it into the final version — which the Senate also has to pass — the Office for the Director of National Intelligence (ODNI) will have 60 days after the Act becomes law to produce a risk assessment. The assessment will look into “the counterintelligence risks of, and the exposure of intelligence community personnel to, tracking by foreign adversaries through advertising technology data,” the Act states.

Edwards says he’s hoping those changes pass, because what he found with Pushwoosh is likely just a drop in a bucket.

“I’m hoping that Congress acts on that,” he said. “If they were to put a requirement that there’s an annual audit of risks from foreign ad tech, that would at least force people to identify and document those connections.”

Lawsuit Seeks Food Benefits Stolen By Skimmers

By BrianKrebs

A nonprofit organization is suing the state of Massachusetts on behalf of thousands of low-income families who were collectively robbed of more than a $1 million in food assistance benefits by card skimming devices secretly installed at cash machines and grocery store checkout lanes across the state. Federal law bars states from replacing these benefits using federal funds, and a recent rash of skimming incidents nationwide has disproportionately affected those receiving food assistance via state-issued prepaid debit cards.

The Massachusetts SNAP benefits card looks more like a library card than a payment card.

On Nov. 4, The Massachusetts Law Reform Institute (MLRI) filed a class action lawsuit on behalf of low-income families whose Supplemental Nutrition and Assistance Program (SNAP) benefits were stolen from their accounts. The SNAP program serves over a million people in Massachusetts, and 41 million people nationally.

“Over the past few months, thieves have stolen over a million SNAP dollars from thousands of Massachusetts families – putting their nutrition and economic stability at risk,” the MLRI said in a statement on the lawsuit. “The criminals attach a skimming device on a POS (point of sale) terminal to capture the household’s account information and PIN. The criminals then use that information to make a fake card and steal the SNAP benefits.”

In announcing the lawsuit, the MRLI linked to a story KrebsOnSecurity published last month that examined how skimming thieves increasingly are targeting SNAP payment card holders nationwide. The story looked at how the vast majority of SNAP benefit cards issued by the states do not include the latest chip technology that makes it more difficult and expensive for thieves to clone them.

The story also highlighted how SNAP cardholders usually have little recourse to recover any stolen funds — even in unlikely cases where the victim has gathered mountains of proof to show state and federal officials that the fraudulent withdrawals were not theirs.

Deborah Harris is a staff attorney at the MLRI. Harris said the goal of the lawsuit is to force Massachusetts to reimburse SNAP skimming victims using state funds, and to convince The U.S. Department of Agriculture (USDA) — which funds the program that states draw from — to change its policies and allow states to replace stolen benefits with federal funds.

“Ultimately we think it’s the USDA that needs to step up and tell states they have a duty to restore the stolen benefits, and that USDA will cover the cost at least until there is better security in place, such as chip cards,” Harris told KrebsOnSecurity.

“The losses we’re talking about are relatively small in the scheme of total SNAP expenditures which are billions,” she said. “But if you are a family that can’t pay for food because you suddenly don’t have money in your account, it’s devastating for the family.”

The USDA has not said it will help states restore the stolen funds. But on Oct. 31, 2022, the agency released guidance (PDF) whose primary instructions were included in an appendix titled, Card Security Options Available to Households. Notably, the USDA did not mention the idea of shifting to chip-based SNAP benefits cards.

The recently issued USDA guidance.

“The guidance generally continues to make households responsible for preventing the theft of their benefits as well as for suffering the loss when benefits are stolen through no fault of the household,” Harris said. “Many of the recommendations are not practical for households who don’t have a smartphone to receive text messages and aren’t able to change their PIN after each transaction and keep track of the new PIN.”

Harris said three of the four recommendations are not currently available in Massachusetts, and they are very likely not currently available in other states. For example, she said, Massachusetts households do not have the option of freezing or locking their cards between transactions. Nor do they receive alerts about transactions. And they most certainly don’t have any way to block out-of-state transactions.

“Perhaps these are options that [card] processors and states could provide, but they are not available now as far as we know,” Harris said. “Most likely they would take time to implement.”

The Center for Law and Social Policy (CLASP) recently published Five Ways State Agencies Can Support EBT Users at Risk of Skimming. CLASP says while it is true states can’t use federal funds to replace benefits unless the loss was due to a “system error,” states could use their own funds.

“Doing so will ensure families don’t have to go without food, gas money, or their rent for the month,” CLASP wrote.

That would help address the symptoms of card skimming, but not a root cause. Hardly anyone is suggesting the obvious, which is to equip SNAP benefit cards with the same security technology afforded to practically everyone else participating in the U.S. banking system.

There are several reasons most state-issued SNAP benefit cards do not include chips. For starters, nobody says they have to. Also, it’s a fair bit more expensive to produce chip cards versus plain old magnetic stripe cards, and many state assistance programs are chronically under-funded. Finally, there is no vocal (or at least well-heeled) constituency advocating for change.

Patch Tuesday, November 2022 Election Edition

By BrianKrebs

Let’s face it: Having “2022 election” in the headline above is probably the only reason anyone might read this story today. Still, while most of us here in the United States are anxiously awaiting the results of how well we’ve patched our Democracy, it seems fitting that Microsoft Corp. today released gobs of security patches for its ubiquitous Windows operating systems. November’s patch batch includes fixes for a whopping six zero-day security vulnerabilities that miscreants and malware are already exploiting in the wild.

Probably the scariest of the zero-day flaws is CVE-2022-41128, a “critical” weakness in the Windows scripting languages that could be used to foist malicious software on vulnerable users who do nothing more than browse to a hacked or malicious site that exploits the weakness. Microsoft credits Google with reporting the vulnerability, which earned a CVSS score of 8.8.

CVE-2022-41073 is a zero-day flaw in the Windows Print Spooler, a Windows component that Microsoft has patched mightily over the past year. Kevin Breen, director of cyber threat research at Immersive Labs, noted that the print spooler has been a popular target for vulnerabilities in the last 12 months, with this marking the 9th patch.

The third zero-day Microsoft patched this month is CVE-2022-41125, which is an “elevation of privilege” vulnerability in the Windows Cryptography API: Next Generation (CNG) Key Isolation Service, a service for isolating private keys. Satnam Narang, senior staff research engineer at Tenable, said exploitation of this vulnerability could grant an attacker SYSTEM privileges.

The fourth zero-day, CVE-2022-41091, was previously disclosed and widely reported on in October. It is a Security Feature Bypass of “Windows Mark of the Web” – a mechanism meant to flag files that have come from an untrusted source.

The other two zero-day bugs Microsoft patched this month were for vulnerabilities being exploited in Exchange Server. News that these two Exchange flaws were being exploited in the wild surfaced in late September 2022, and many were surprised when Microsoft let October’s Patch Tuesday sail by without issuing official patches for them (the company instead issued mitigation instructions that it was forced to revise multiple times). Today’s patch batch addresses both issues.

Greg Wiseman, product manager at Rapid7, said the Exchange flaw CVE-2022-41040 is a “critical” elevation of privilege vulnerability, and CVE-2022-41082 is considered Important, allowing Remote Code Execution (RCE) when PowerShell is accessible to the attacker.

“Both vulnerabilities have been exploited in the wild,” Wiseman said. “Four other CVEs affecting Exchange Server have also been addressed this month. Three are rated as Important, and CVE-2022-41080 is another privilege escalation vulnerability considered Critical. Customers are advised to update their Exchange Server systems immediately, regardless of whether any previously recommended mitigation steps have been applied. The mitigation rules are no longer recommended once systems have been patched.”

Adobe usually issues security updates for its products on Patch Tuesday, but it did not this month. For a closer look at the patches released by Microsoft today and indexed by severity and other metrics, check out the always-useful 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.

As always, please consider backing up your system or at least your important documents and data before applying system updates. And if you run into any problems with these updates, please drop a note about it here in the comments.

Microsoft Patch Tuesday, August 2022 Edition

By BrianKrebs

Microsoft today released updates to fix a record 141 security vulnerabilities in its Windows operating systems and related software. Once again, Microsoft is patching a zero-day vulnerability in the Microsoft Support Diagnostics Tool (MSDT), a service built into Windows. Redmond also addressed multiple flaws in Exchange Server — including one that was disclosed publicly prior to today — and it is urging organizations that use Exchange for email to update as soon as possible and to enable additional protections.

In June, Microsoft patched a vulnerability in MSDT dubbed “Follina” that had been used in active attacks for at least three months prior. This latest MSDT bug — CVE-2022-34713 — is a remote code execution flaw that requires convincing a target to open a booby-trapped file, such as an Office document. Microsoft this month also issued a different patch for another MSDT flaw, tagged as CVE-2022-35743.

The publicly disclosed Exchange flaw is CVE-2022-30134, which is an information disclosure weakness. Microsoft also released fixes for three other Exchange flaws that rated a “critical” label, meaning they could be exploited remotely to compromise the system and with no help from users. Microsoft says addressing some of the Exchange vulnerabilities fixed this month requires administrators to enable Windows Extended protection on Exchange Servers. See Microsoft’s blog post on the Exchange Server updates for more details.

“If your organization runs local exchange servers, this trio of CVEs warrant an urgent patch,” said Kevin Breen, director of cyber threat research for Immerse Labs. “Exchanges can be treasure troves of information, making them valuable targets for attackers. With CVE-2022-24477, for example, an attacker can gain initial access to a user’s host and could take over the mailboxes for all exchange users, sending and reading emails and documents. For attackers focused on Business Email Compromise this kind of vulnerability can be extremely damaging.”

The other two critical Exchange bugs are tracked as CVE-2022-24516 and CVE-2022-21980. It’s difficult to believe it’s only been a little more than a year since malicious hackers worldwide pounced in a bevy of zero-day Exchange vulnerabilities to remotely compromise the email systems for hundreds of thousands of organizations running Exchange Server locally for email. That lingering catastrophe is reminder enough that critical Exchange bugs deserve immediate attention.

The SANS Internet Storm Center‘s rundown on Patch Tuesday warns that a critical remote code execution bug in the Windows Point-to-Point Protocol (CVE-2022-30133) could become “wormable” — a threat capable of spreading across a network without any user interaction.

“Another critical vulnerability worth mentioning is an elevation of privilege affecting Active Directory Domain Services (CVE-2022-34691),” SANS wrote. “According to the advisory, ‘An authenticated user could manipulate attributes on computer accounts they own or manage, and acquire a certificate from Active Directory Certificate Services that would allow elevation of privilege to System.’ A system is vulnerable only if Active Directory Certificate Services is running on the domain. The CVSS for this vulnerability is 8.8.”

Breen highlighted a set of four vulnerabilities in Visual Studio that earned Microsoft’s less-dire “important” rating but that nevertheless could be vitally important for the security of developer systems.

“Developers are empowered with access to API keys and deployment pipelines that, if compromised, could be significantly damaging to organizations,” he said. “So it’s no surprise they are often targeted by more advanced attackers. Patches for their tools should not be overlooked. We’re seeing a continued trend of supply-chain compromise too, making it vital that we ensure developers, and their tools, are kept up-to-date with the same rigor we apply to standard updates.”

Greg Wiseman, product manager at Rapid7, pointed to an interesting bug Microsoft patched in Windows Hello, the biometric authentication mechanism for Windows 10.  Microsoft notes that the successful exploitation of the weakness requires physical access to the target device, but would allow an attacker to bypass a facial recognition check.

Wiseman said despite the record number of vulnerability fixes from Redmond this month, the numbers are slightly less dire.

“20 CVEs affect their Chromium-based Edge browser and 34 affect Azure Site Recovery (up from 32 CVEs affecting that product last month),” Wiseman wrote. “As usual, OS-level updates will address a lot of these, but note that some extra configuration is required to fully protect Exchange Server this month.”

As it often does on Patch Tuesday, Adobe has also released security updates for many of its products, including Acrobat and Reader, Adobe Commerce and Magento Open Source. More details here.
