BlackCat Ransomware Group Implodes After Apparent $22M Payment by Change Healthcare

By BrianKrebs

There are indications that U.S. healthcare giant Change Healthcare has made a $22 million extortion payment to the infamous BlackCat ransomware group (a.k.a. “ALPHV“) as the company struggles to bring services back online amid a cyberattack that has disrupted prescription drug services nationwide for weeks. However, the cybercriminal who claims to have given BlackCat access to Change’s network says the crime gang cheated them out of their share of the ransom, and that they still have the sensitive data Change reportedly paid the group to destroy. Meanwhile, the affiliate’s disclosure appears to have prompted BlackCat to cease operations entirely.

In the third week of February, a cyber intrusion at Change Healthcare began shutting down important healthcare services as company systems were taken offline. It soon emerged that BlackCat was behind the attack, which has disrupted the delivery of prescription drugs for hospitals and pharmacies nationwide for nearly two weeks.

On March 1, a cryptocurrency address that security researchers had already mapped to BlackCat received a single transaction worth approximately $22 million. On March 3, a BlackCat affiliate posted a complaint to the exclusive Russian-language ransomware forum Ramp saying that Change Healthcare had paid a $22 million ransom for a decryption key, and to prevent four terabytes of stolen data from being published online.

The affiliate claimed BlackCat/ALPHV took the $22 million payment but never paid him his percentage of the ransom. BlackCat is known as a “ransomware-as-service” collective, meaning they rely on freelancers or affiliates to infect new networks with their ransomware. And those affiliates in turn earn commissions ranging from 60 to 90 percent of any ransom amount paid.

“But after receiving the payment ALPHV team decide to suspend our account and keep lying and delaying when we contacted ALPHV admin,” the affiliate “Notchy” wrote. “Sadly for Change Healthcare, their data [is] still with us.”

Change Healthcare has neither confirmed nor denied paying, and has responded to multiple media outlets with a similar non-denial statement — that the company is focused on its investigation and on restoring services.

Assuming Change Healthcare did pay to keep their data from being published, that strategy seems to have gone awry: Notchy said the list of affected Change Healthcare partners they’d stolen sensitive data from included Medicare and a host of other major insurance and pharmacy networks.

On the bright side, Notchy’s complaint seems to have been the final nail in the coffin for the BlackCat ransomware group, which was infiltrated by the FBI and foreign law enforcement partners in late December 2023. As part of that action, the government seized the BlackCat website and released a decryption tool to help victims recover their systems.

BlackCat responded by re-forming, and increasing affiliate commissions to as much as 90 percent. The ransomware group also declared it was formally removing any restrictions or discouragement against targeting hospitals and healthcare providers.

However, instead of responding that they would compensate and placate Notchy, a representative for BlackCat said today the group was shutting down and that it had already found a buyer for its ransomware source code.

The seizure notice now displayed on the BlackCat darknet website.

“There’s no sense in making excuses,” wrote the RAMP member “Ransom.” “Yes, we knew about the problem, and we were trying to solve it. We told the affiliate to wait. We could send you our private chat logs where we are shocked by everything that’s happening and are trying to solve the issue with the transactions by using a higher fee, but there’s no sense in doing that because we decided to fully close the project. We can officially state that we got screwed by the feds.”

BlackCat’s website now features a seizure notice from the FBI, but several researchers noted that this image seems to have been merely cut and pasted from the notice the FBI left in its December raid of BlackCat’s network. The FBI has not responded to requests for comment.

Fabian Wosar, head of ransomware research at the security firm Emsisoft, said it appears BlackCat leaders are trying to pull an “exit scam” on affiliates by withholding many ransomware payment commissions at once and shutting down the service.

“ALPHV/BlackCat did not get seized,” Wosar wrote on Twitter/X today. “They are exit scamming their affiliates. It is blatantly obvious when you check the source code of their new takedown notice.”

Dmitry Smilyanets, a researcher for the security firm Recorded Future, said BlackCat’s exit scam was especially dangerous because the affiliate still has all the stolen data, and could still demand additional payment or leak the information on his own.

“The affiliates still have this data, and they’re mad they didn’t receive this money, Smilyanets told Wired.com. “It’s a good lesson for everyone. You cannot trust criminals; their word is worth nothing.”

BlackCat’s apparent demise comes closely on the heels of the implosion of another major ransomware group — LockBit, a ransomware gang estimated to have extorted over $120 million in payments from more than 2,000 victims worldwide. On Feb. 20, LockBit’s website was seized by the FBI and the U.K.’s National Crime Agency (NCA) following a months-long infiltration of the group.

LockBit also tried to restore its reputation on the cybercrime forums by resurrecting itself at a new darknet website, and by threatening to release data from a number of major companies that were hacked by the group in the weeks and days prior to the FBI takedown.

But LockBit appears to have since lost any credibility the group may have once had. After a much-promoted attack on the government of Fulton County, Ga., for example, LockBit threatened to release Fulton County’s data unless paid a ransom by Feb. 29. But when Feb. 29 rolled around, LockBit simply deleted the entry for Fulton County from its site, along with those of several financial organizations that had previously been extorted by the group.

Fulton County held a press conference to say that it had not paid a ransom to LockBit, nor had anyone done so on their behalf, and that they were just as mystified as everyone else as to why LockBit never followed through on its threat to publish the county’s data. Experts told KrebsOnSecurity LockBit likely balked because it was bluffing, and that the FBI likely relieved them of that data in their raid.

Smilyanets’ comments are driven home in revelations first published last month by Recorded Future, which quoted an NCA official as saying LockBit never deleted the data after being paid a ransom, even though that is the only reason many of its victims paid.

“If we do not give you decrypters, or we do not delete your data after payment, then nobody will pay us in the future,” LockBit’s extortion notes typically read.

Hopefully, more companies are starting to get the memo that paying cybercrooks to delete stolen data is a losing proposition all around.

Russian Cybersecurity Executive Arrested for Alleged Role in 2012 Megahacks

By BrianKrebs

Nikita Kislitsin, formerly the head of network security for one of Russia’s top cybersecurity firms, was arrested last week in Kazakhstan in response to 10-year-old hacking charges from the U.S. Department of Justice. Experts say Kislitsin’s prosecution could soon put the Kazakhstan government in a sticky diplomatic position, as the Kremlin is already signaling that it intends to block his extradition to the United States.

Nikita Kislitsin, at a security conference in Russia.

Kislitsin is accused of hacking into the now-defunct social networking site Formspring in 2012, and conspiring with another Russian man convicted of stealing tens of millions of usernames and passwords from LinkedIn and Dropbox that same year.

In March 2020, the DOJ unsealed two criminal hacking indictments against Kislitsin, who was then head of security at Group-IB, a cybersecurity company that was founded in Russia in 2003 and operated there for more than a decade before relocating to Singapore.

Prosecutors in Northern California indicted Kislitsin in 2014 for his alleged role in stealing account data from Formspring. Kislitsin also was indicted in Nevada in 2013, but the Nevada indictment does not name his alleged victim(s) in that case.

However, documents unsealed in the California case indicate Kislitsin allegedly conspired with Yevgeniy Nikulin, a Russian man convicted in 2020 of stealing 117 million usernames and passwords from Dropbox, Formspring and LinkedIn in 2012. Nikulin is currently serving a seven-year sentence in the U.S. prison system.

As first reported by Cyberscoop in 2020, a trial brief in the California investigation identified Nikulin, Kislitsin and two alleged cybercriminals — Oleg Tolstikh and Oleksandr Vitalyevich Ieremenko — as being present during a 2012 meeting at a Moscow hotel, where participants allegedly discussed starting an internet café business.

A 2010 indictment out of New Jersey accuses Ieremenko and six others with siphoning nonpublic information from the U.S. Securities & Exchange Commission (SEC) and public relations firms, and making $30 million in illegal stock trades based on the proprietary information they stole.

[The U.S. Secret Service has an outstanding $1 million reward for information leading to the arrest of Ieremenko (Александр Витальевич Еременко), who allegedly went by the hacker handles “Zl0m” and “Lamarez.”]

Kislitsin was hired by Group-IB in January 2013, nearly six months after the Formspring hack. Group-IB has since moved its headquarters to Singapore, and in April 2023 the company announced it had fully exited the Russian market.

In a statement provided to KrebsOnSecurity, Group-IB said Mr. Kislitsin is no longer an employee, and that he now works for a Russian organization called FACCT, which stands for “Fight Against Cybercrime Technologies.”

“Dmitry Volkov, co-founder and CEO, sold his stake in Group-IB’s Russia-based business to the company’s local management,” the statement reads. “The stand-alone business in Russia has been operating under the new brand FACCT ever since and will continue to operate as a separate company with no connection to Group-IB.”

FACCT says on its website that it is a “Russian developer of technologies for combating cybercrime,” and that it works with clients to fight targeted attacks, data leaks, fraud, phishing and brand abuse. In a statement published online, FACCT said Kislitsin is responsible for developing its network security business, and that he remains under temporary detention in Kazakhstan “to study the basis for extradition arrest at the request of the United States.”

“According to the information we have, the claims against Kislitsin are not related to his work at FACCT, but are related to a case more than 10 years ago when Nikita worked as a journalist and independent researcher,” FACCT wrote.

From 2006 to 2012, Kislitsin was editor-in-chief of “Hacker,” a popular Russian-language monthly magazine that includes articles on information and network security, programming, and frequently features interviews with and articles penned by notable or wanted Russian hackers.

“We are convinced that there are no legal grounds for detention on the territory of Kazakhstan,” the FACCT statement continued. “The company has hired lawyers who have been providing Nikita with all the necessary assistance since last week, and we have also sent an appeal to the Consulate General of the Russian Federation in Kazakhstan to assist in protecting our employee.”

FACCT indicated that the Kremlin has already intervened in the case, and the Russian government claims Kislitsin is wanted on criminal charges in Russia and must instead be repatriated to his homeland.

“The FACCT emphasizes that the announcement of Nikita Kislitsin on the wanted list in the territory of the Russian Federation became known only today, June 28, 6 days after the arrest in Kazakhstan,” FACCT wrote. “The company is monitoring developments.”

The Kremlin followed a similar playbook in the case of Aleksei Burkov, a cybercriminal who long operated two of Russia’s most exclusive underground hacking forums. Burkov was arrested in 2015 by Israeli authorities, and the Russian government fought Burkov’s extradition to the U.S. for four years — even arresting and jailing an Israeli woman on phony drug charges to force a prisoner swap.

That effort ultimately failed: Burkov was sent to America, pleaded guilty, and was sentenced to nine years in prison.

Arkady Bukh is a U.S. attorney who has represented dozens of accused hackers from Russia and Eastern Europe who were extradited to the United States over the years. Bukh said Moscow is likely to turn the Kislitsin case into a diplomatic time bomb for Kazakhstan, which shares an enormous border and a great deal of cultural ties with Russia. A 2009 census found that Russians make up about 24 percent of the population of Kazakhstan.

“That would put Kazakhstan at a crossroads to choose between unity with Russia or going with the West,” Bukh said. “If that happens, Kazakhstan may have to make some very unpleasant decisions.”

Group-IB’s exodus from Russia comes as its former founder and CEO Ilya Sachkov remains languishing in a Russian prison, awaiting a farcical trial and an inevitable conviction on charges of treason. In September 2021, the Kremlin issued treason charges against Sachkov, although it has so far refused to disclose any details about the allegations.

Sachkov’s pending treason trial has been the subject of much speculation among denizens of Russian cybercrime forums, and the consensus seems to be that Sachkov and Group-IB were seen as a little too helpful to the DOJ in its various investigations involving top Russian hackers.

Indeed, since its inception in 2003, Group-IB’s researchers have helped to identify, disrupt and even catch a number of high-profile Russian hackers, most of whom got busted after years of criminal hacking because they made the unforgivable mistake of stealing from their own citizens.

When the indictments against Kislitsin were unsealed in 2020, Group-IB issued a lengthy statement attesting to his character and saying they would help him with his legal defense. As part of that statement, Group-IB noted that “representatives of the Group-IB company and, in particular, Kislitsin, in 2013, on their own initiative, met with employees of the US Department of Justice to inform them about the research work related to the underground, which was carried out by Kislitsin in 2012.”

Phishing Domains Tanked After Meta Sued Freenom

By BrianKrebs

The number of phishing websites tied to domain name registrar Freenom dropped precipitously in the months surrounding a recent lawsuit from social networking giant Meta, which alleged the free domain name provider has a long history of ignoring abuse complaints about phishing websites while monetizing traffic to those abusive domains.

The volume of phishing websites registered through Freenom dropped considerably since the registrar was sued by Meta. Image: Interisle Consulting.

Freenom is the domain name registry service provider for five so-called “country code top level domains” (ccTLDs), including .cf for the Central African Republic; .ga for Gabon; .gq for Equatorial Guinea; .ml for Mali; and .tk for Tokelau.

Freenom has always waived the registration fees for domains in these country-code domains, but the registrar also reserves the right to take back free domains at any time, and to divert traffic to other sites — including adult websites. And there are countless reports from Freenom users who’ve seen free domains removed from their control and forwarded to other websites.

By the time Meta initially filed its lawsuit in December 2022, Freenom was the source of well more than half of all new phishing domains coming from country-code top-level domains. Meta initially asked a court to seal its case against Freenom, but that request was denied. Meta withdrew its December 2022 lawsuit and re-filed it in March 2023.

“The five ccTLDs to which Freenom provides its services are the TLDs of choice for cybercriminals because Freenom provides free domain name registration services and shields its customers’ identity, even after being presented with evidence that the domain names are being used for illegal purposes,” Meta’s complaint charged. “Even after receiving notices of infringement or phishing by its customers, Freenom continues to license new infringing domain names to those same customers.”

Meta pointed to research from Interisle Consulting Group, which discovered in 2021 and again last year that the five ccTLDs operated by Freenom made up half of the Top Ten TLDs most abused by phishers.

Interisle partner Dave Piscitello said something remarkable has happened in the months since the Meta lawsuit.

“We’ve observed a significant decline in phishing domains reported in the Freenom commercialized ccTLDs in months surrounding the lawsuit,” Piscitello wrote on Mastodon. “Responsible for over 60% of phishing domains reported in November 2022, Freenom’s percentage has dropped to under 15%.”

Interisle collects data from 12 major blocklists for spam, malware, and phishing, and it receives phishing-specific data from Spamhaus, Phishtank, OpenPhish and the APWG Ecrime Exchange. The company publishes historical data sets quarterly, both on malware and phishing.

Piscitello said it’s too soon to tell the full impact of the Freenom lawsuit, noting that Interisle’s sources of spam and phishing data all have different policies about when domains are removed from their block lists.

“One of the things we don’t have visibility into is how each of the blocklists determine to remove a URL from their lists,” he said. “Some of them time out [listed domains] after 14 days, some do it after 30, and some keep them forever.”

Freenom did not respond to requests for comment.

This is the second time in as many years that a lawsuit by Meta against a domain registrar has disrupted the phishing industry. In March 2020, Meta sued domain registrar giant Namecheap, alleging cybersquatting and trademark infringement.

The two parties settled the matter in April 2022. While the terms of that settlement have not been disclosed, new phishing domains registered through Namecheap declined more than 50 percent the following quarter, Interisle found.

Unfortunately, the lawsuits have had little effect on the overall number of phishing attacks and phishing-related domains, which have steadily increased in volume over the years.  Piscitello said the phishers tend to gravitate toward registrars that offer the least resistance and lowest price per domain. And with new top-level domains constantly being introduced, there is rarely a shortage of super low-priced domains.

“The abuse of a new top-level domain is largely the result of one registrar’s portfolio,” Piscitello told KrebsOnSecurity. “Alibaba or Namecheap or another registrar will run a promotion for a cheap domain, and then we’ll see flocking and migration of the phishers to that TLD. It’s like strip mining, where they’ll buy hundreds or thousands of domains, use those in a campaign, exhaust that TLD and then move on to another provider.”

Piscitello said despite the steep drop in phishing domains coming out of Freenom, the alternatives available to phishers are many. After all, there are more than 2,000 accredited domain registrars, not to mention dozens of services that let anyone set up a website for free without even owning a domain.

“There is no evidence that the trend line is even going to level off,” he said. “I think what the Meta lawsuit tells us is that litigation is like giving someone a standing eight count. It temporarily disrupts a process. And in that sense, litigation appears to be working.”

Everything You Need to Know About Identity Remediation

By McAfee

There are no ifs, ands, or buts about it: A stolen identity creates a mess. Once they have a few key pieces of personally identifiable information (PII), an identity thief can open new credit lines, create convincing new identities, and ruin an innocent person’s good credit. 

If you suspect you’ve been affected by identity theft, acting quickly is key to stopping the thief and repairing the damage. Here are the definitive five steps of identity remediation, or the process of restoring and protecting the privacy of your identity. 

1. Freeze Your Credit

With a stolen identity in hand, thieves can open new lines of credit or apply for large loans using someone else’s excellent credit score for leverage. If undetected, fraudsters can run up huge bills, never pay them, and in turn, ruin the credit score that you spent years perfecting. When you suspect or confirm that your identity has been compromised and you’re in the United States, alert the three major credit bureaus: Equifax, TransUnion, and Experian.  

Freezing your credit means that no one (not even you) can open a new credit card or bank account. This prevents criminals from misusing your identity. Initiating a credit freeze is free and it doesn’t affect your credit score.  

2. File a Report

Once you suspect a criminal has stolen your identity, file a report with the Federal Trade Commission. Its official identity theft website includes a form for you to detail the circumstances. From there, the FTC will investigate. 

It’s important to file a report because law enforcement can get involved and hopefully stop the criminal from striking again. Also, an official document from law enforcement or the FTC may help your bank and the credit bureaus resolve the damage. 

3. Change Your Passwords and Credit Cards

Whenever a company with which you have an account is breached, the first step you should take is to quickly change your password. The same goes for when your identity is compromised with the added step of getting in touch with your banks and asking their fraud department to issue you new credit and debit cards and put them on alert for possible suspicious charges. 

Having unique passwords for all your accounts is crucial to keeping them secure. For instance, if one of your accounts is breached and a cybercriminal lifts that username and password combination, they may then attempt to use it on other sites. To ensure you have strong passwords and passphrases for every site, consider using password manager software. Password managers are incredibly secure and make it so you only have to remember one password ever again.  

4. Collaborate With Credit Bureaus

In addition to freezing your credit, you may have to sync up with each bureau to remedy any damage the identity thief may have done to your credit. Each bureau’s fraud department is very familiar with these scenarios, so their customer service department is experienced and more than willing to help you work through it. 

5. Sign Up for Credit Monitoring

Once you’ve cleaned up the immediate mess made by an identity thief, it’s important to continuously monitor your identity in case the thief is biding their time or pieces of your PII are still circulating on the dark web. Plus, the headache of one compromised identity incident is enough for someone to never want it to happen again. Identity monitoring is a very thorough process that will give you peace of mind that you’ll be protected and can enjoy your online life safely.  

How McAfee Makes Identity Remediation Less of a Headache 

These five steps, while important, can be tedious. It may require a lot of patience to sit on hold and sift through all the relevant forms. Luckily, McAfee is an excellent partner who can help you with all your identity remediation needs with just one service: McAfee+ Ultimate. For example, security freeze is an easy way to put a halt on your credit. McAfee’s identity monitoring service monitors up to 60 unique types of personal details. If your PII appears on the dark web, Personal Data Cleanup can remove it.  

Recover and move forward confidently after an identity theft with McAfee by your side.

Mitigation for Exchange Zero-Days Bypassed! Microsoft Issues New Workarounds

By Ravie Lakshmanan
Microsoft has updated its mitigation measures for the newly disclosed and actively exploited zero-day flaws in Exchange Server after it was found that they could be trivially bypassed. The two vulnerabilities, tracked as CVE-2022-41040 and CVE-2022-41082, have been codenamed ProxyNotShell due to similarities to another set of flaws called ProxyShell, which the tech giant resolved last year.

ProxyNotShell – the New Proxy Hell?

Microsoft: Two New 0-Day Flaws in Exchange Server

By BrianKrebs

Microsoft Corp. is investigating reports that attackers are exploiting two previously unknown vulnerabilities in Exchange Server, a technology many organizations rely on to send and receive email. Microsoft says it is expediting work on software patches to plug the security holes. In the meantime, it is urging a subset of Exchange customers to enable a setting that could help mitigate ongoing attacks.

In customer guidance released Thursday, Microsoft said it is investigating two reported zero-day flaws affecting Microsoft Exchange Server 2013, 2016, and 2019. CVE-2022-41040, is a Server-Side Request Forgery (SSRF) vulnerability that can enable an authenticated attacker to remotely trigger the second zero-day vulnerability — CVE-2022-41082 — which allows remote code execution (RCE) when PowerShell is accessible to the attacker.

Microsoft said Exchange Online has detections and mitigation in place to protect customers. Customers using on-premises Microsoft Exchange servers are urged to review the mitigations suggested in the security advisory, which Microsoft says should block the known attack patterns.

Vietnamese security firm GTSC on Thursday published a writeup on the two Exchange zero-day flaws, saying it first observed the attacks in early August being used to drop “webshells.” These web-based backdoors offer attackers an easy-to-use, password-protected hacking tool that can be accessed over the Internet from any browser.

“We detected webshells, mostly obfuscated, being dropped to Exchange servers,” GTSC wrote. “Using the user-agent, we detected that the attacker uses Antsword, an active Chinese-based opensource cross-platform website administration tool that supports webshell management. We suspect that these come from a Chinese attack group because the webshell codepage is 936, which is a Microsoft character encoding for simplified Chinese.”

GTSC’s advisory includes details about post-compromise activity and related malware, as well as steps it took to help customers respond to active compromises of their Exchange Server environment. But the company said it would withhold more technical details of the vulnerabilities for now.

In March 2021, hundreds of thousands of organizations worldwide had their email stolen and multiple backdoor webshells installed, all thanks to four zero-day vulnerabilities in Exchange Server.

Granted, the zero-day flaws that powered that debacle were far more critical than the two detailed this week, and there are no signs yet that exploit code has been publicly released (that will likely change soon). But part of what made last year’s Exchange Server mass hack so pervasive was that vulnerable organizations had little or no advance notice on what to look for before their Exchange Server environments were completely owned by multiple attackers.

Microsoft is quick to point out that these zero-day flaws require an attacker to have a valid username and password for an Exchange user, but this may not be such a tall order for the hackers behind these latest exploits against Exchange Server.

Steven Adair is president of Volexity, the Virginia-based cybersecurity firm that was among the first to sound the alarm about the Exchange zero-days targeted in the 2021 mass hack. Adair said GTSC’s writeup includes an Internet address used by the attackers that Volexity has tied with high confidence to a China-based hacking group that has recently been observed phishing Exchange users for their credentials.

In February 2022, Volexity warned that this same Chinese hacking group was behind the mass exploitation of a zero-day vulnerability in the Zimbra Collaboration Suite, which is a competitor to Microsoft Exchange that many enterprises use to manage email and other forms of messaging.

If your organization runs Exchange Server, please consider reviewing the Microsoft mitigations and the GTSC post-mortem on their investigations.

Transacting in Person with Strangers from the Internet

By BrianKrebs

Communities like Craigslist, OfferUp, Facebook Marketplace and others are great for finding low- or no-cost stuff that one can pick up directly from a nearby seller, and for getting rid of useful things that don’t deserve to end up in a landfill. But when dealing with strangers from the Internet, there is always a risk that the person you’ve agreed to meet has other intentions.

Nearly all U.S. states now have designated safe trading stations — mostly at local police departments — which ensure that all transactions are handled in plain view of both the authorities and security cameras.

These safe trading places exist because sometimes in-person transactions from the Internet don’t end well for one or more parties involved. The website Craigslistkillers has catalogued news links for at least 132 murders linked to Craigslist transactions since 2015. Many of these killings involved high-priced items like automobiles and consumer electronics, where the prospective buyer apparently intended all along to kill the owner and steal the item offered for sale. Others were motivated simply by a desire to hurt people.

This is not to say that using Craigslist is uniquely risky or dangerous; I’m sure the vast majority of transactions generated by the site end amicably and without physical violence. And that probably holds true for all of Craigslist’s competitors.

Still, the risk of a deal going badly when one meets total strangers from the Internet is not zero, and so it’s only sensible to take a few simple precautions. For example, choosing to transact at a designated safe place such as a police station dramatically reduces the likelihood that anyone wishing you harm would even show up.

I recently stumbled upon one of these designated exchange places by accident, hence my interest in learning more about them. The one I encountered was at a Virginia county sheriff’s office, and it has two parking spots reserved with a sign that reads, “Internet Purchase & Exchange Location: This Area is Under 24 Hour Video Surveillance” [image above].

According to the list maintained at Safetradestations.com, there are four other such designated locations in Northern Virginia. And it appears most states now have them in at least some major cities. Safeexchangepoint.com also has a searchable index of safe trading locations in the United States and Canada.

Granted, not everyone is going to live close to one of these designated trading stations. Or maybe what you want to buy, sell or trade you’d rather not have recorded in front of police cameras. Either way, here are a few tips on staying safe while transacting in real life with strangers from the Internet (compliments of the aforementioned safe trading websites).

The safest exchange points are easily accessible and in a well-lit, public place where transactions are visible to others nearby. Try to arrange a meeting time that is during daylight hours, and consider bringing a friend along — especially when dealing with high-value items like laptops and smart phones.

Safeexchangepoint.com also advises that police or merchants that host their own exchange locations generally won’t get involved in the details of your transaction unless specified otherwise, and that many police departments (but not all) are willing to check the serial number of an item for sale to make sure it’s not known to be stolen property.

Of course, it’s not always practical or possible to haul that old sofa to the local police department, or a used car that isn’t working. In those situations, safetradestations.com has some decent suggestions:

  • Meet at a police station where you can exchange and photocopy each others’ identification papers, such as a driver’s license. Do NOT carry cash to this location.
  • Photocopy the license or identification paper, or use your phone to photograph it.
  • Email the ID information to a friend, or to someone trusted (not to yourself).
  • If you’re selling at home, or going to someone’s home, never be outnumbered. If you’re at home, make sure you have two or three people there — and tell the person who is coming that you will have others with you.
  • At home or an apartment, NEVER let someone go anywhere unaccompanied. Always make sure they are escorted.
  • Never let more than one group come to your home at one time to buy or sell.
  • Beware of common scams, like checks for an amount higher than the amount of the deal; “cashier’s checks” that are forged and presented when the bank is closed.
  • If you are given a cashier’s check, money order or other equivalent, call the bank — at the number listed online, not a number the buyer gives you — to verify the validity of the check.

Kicking Off a New School Year with New Online Habits

By Toni Birdsong

Most every parent loves a new school year. Most likely because the beloved milestone offers us a clean slate and a chance to do things better, shape new habits, and close those digital safety gaps.

The hope that fuels change is a powerful thing. However, if you want to ensure your new habits stick, there’s some science you might consider. Psychologists suggest that to make a new change permanent, you should start with smaller, micro-size choices that will lead to sustainable patterns and habits. Micro habits allow you to take safe steps that are too small to fail but effective enough to generate long-term change. 

Committing to Micro-Habits 

Breaking down the task online safety into bite-sized pieces is a great approach for parents eager to put better habits into play this year. Establishing new ground rules doesn’t have to include restrictions, tantrums, or tears. You can start small, commit to work together, and build your new habits over time. 

So often in this blog we offer a combination of practical digital tips proven to work such as robust password protocols, privacy settings, parental controls, smart phone protection, and social network/app safety.  

Today, however, we will flip that approach and give you some foundations that will no doubt support and amplify your family’s daily online safety efforts. Ready? Here we go! 

5 Foundations of Healthy Family Tech Habits 

1. Put connection first.

We’re all connected 24/7 but to what? Equipping kids to make wise decisions online begins with intentional, face-to-face connection at home with a parent or caregiver. When the parent-child relationship is strong, trust grows, and conversation flows. If and when a challenge arises, your child is more likely to turn to you.  

Micro-habit: If your family doesn’t eat dinner together, start with one night a week (stay consistent with the day). Make the dinner table a no-phone zone and spend that time together listening and connecting. Build from there.  

 

2. Step into their world. 

The new school year is a chance to get more involved with your child’s day-to-day communities (on and offline), including their teachers, friend groups, or hobbies. If you’ve been on the sidelines in the past, taking a few steps into their world can give you an exceptional understanding of their online life. Knowing where they go and who they know online has never been more critical, as outlined in our recent Connected Family Report. 

Micro-habit: Does your child have a favorite app? Download it, look around, and understand the culture.  

3. Prioritize sleep. 

Summer—coupled with extra time online (often unmonitored)—can wreak havoc on a child’s sleep patterns, which, in turn, wreaks havoc on a family. If you have a tween or teen, ensuring they get the required hours of sleep is a significant way to keep them safe online. Think about it. Fatigue can impair judgment, increase anxiety, impact grades, and magnify moodiness, putting a child’s physical and emotional wellbeing at risk online and off.  

Micro-habit: Think about setting a phone curfew that everyone agrees on. Giving your child input into the curfew makes it less of a restriction and more of a health or lifestyle shift. Remember, your child’s device is their lifeline to their peers so cutting them off isn’t a long-term solution.  

4. Monitor mental health. 

With kids spending so much time on apps like TikTok, Instagram, Snapchat, and YouTube, those platforms inevitably influence your child more than just about anyone. Be on the lookout for behavior changes in your child that may be connected to digital risks such as cyberbullying, sextortion, gaming addiction, inappropriate content, or connecting with strangers.

Micro-habit: Consider setting time limits that allow your child to enjoy their online hangouts without being consumed or overly influenced by the wrong voices. Apply limits in small blocks at first and grow from there.  

5. Aim for balance. 

Balancing your online life with face-to-face activities and relationships is a must for your child’s physical and emotional wellbeing. But sometimes, striving for that balance can feel overwhelming. Being too stringent can cause big plans to collapse, sending our behaviors in the opposite direction. Balance requires constant re-calibration and pausing to take those small bites. 

Micro-habit: Commit to one family outdoor activity together a month. Take a hike, learn to fish, take up tennis. Make the outings phone-free zones. Be consistent with your monthly micro-habit and build from there.  

It’s been proven that any change you attempt to make ignites a degree of friction. And prolonged friction can discourage your efforts to stick to new habits. Ignore that noise and keep moving forward. Stay the course parents because this is the year your best intentions take shape.

You Can Now Ask Google to Remove Your Phone Number, Email or Address from Search Results

By BrianKrebs

Google said this week it is expanding the types of data people can ask to have removed from search results, to include personal contact information like your phone number, email address or physical address. The move comes just months after Google rolled out a new policy enabling people under the age of 18 (or a parent/guardian) to request removal of their images from Google search results.

Google has for years accepted requests to remove certain sensitive data such as bank account or credit card numbers from search results. In a blog post on Wednesday, Google’s Michelle Chang wrote that the company’s expanded policy now allows for the removal of additional information that may pose a risk for identity theft, such as confidential log-in credentials, email addresses and phone numbers when it appears in Search results.

“When we receive removal requests, we will evaluate all content on the web page to ensure that we’re not limiting the availability of other information that is broadly useful, for instance in news articles,” Chang wrote. “We’ll also evaluate if the content appears as part of the public record on the sites of government or official sources. In such cases, we won’t make removals.”

While Google’s removal of a search result from its index will do nothing to remove the offending content from the site that is hosting it, getting a link decoupled from Google search results is going to make the content at that link far less visible. According to recent estimates, Google enjoys somewhere near 90 percent market share in search engine usage.

KrebsOnSecurity decided to test this expanded policy with what would appear to be a no-brainer request: I asked Google to remove search result for BriansClub, one of the largest (if not THE largest) cybercrime stores for selling stolen payment card data.

BriansClub has long abused my name and likeness to pimp its wares on the hacking forums. Its homepage includes a copy of my credit report, Social Security card, phone bill, and a fake but otherwise official looking government ID card.

The login page for perhaps the most bustling cybercrime store for stolen payment card data.

Briansclub updated its homepage with this information in 2019, after it got massively hacked and a copy of its customer database was shared with this author. The leaked data — which included 26 million credit and debit card records taken from hacked online and brick-and-mortar retailers — was ultimately shared with dozens of financial institutions.

TechCrunch writes that the policy expansion comes six months after Google started allowing people under 18 or their parents request to delete their photos from search results. To do so, users need to specify that they want Google to remove “Imagery of an individual currently under the age of 18” and provide some personal information, the image URLs and search queries that would surface the results. Google also lets you submit requests to remove non-consensual explicit or intimate personal images from Google, along with involuntary fake pornography, TechCrunch notes.

This post will be updated in the event Google responds one way or the other, but that may take a while: Google’s automated response said: “Due to the preventative measures being taken for our support specialists in light of COVID-19, it may take longer than usual to respond to your support request. We apologize for any inconvenience this may cause, and we’ll send you a reply as soon as we can.”

Update: 10:30 p.m. ET: An earlier version of this story incorrectly stated that people needed to show explicit or implicit threats regarding requests to remove information like one’s phone number, address or email address from a search result. A spokesperson for Google said “there is no requirement that we find the content to be harmful or shared in a malicious way.”

Career change? Cybersecurity companies are hiring.

Career change? Cybersecurity companies are hiring.

If you’re thinking career change or career shift, there’s a field that has an estimated 4 million jobs open. Cybersecurity.

According to survey and research data from the International Cybersecurity Organization (ICS)2, there’s a cybersecurity workforce gap—a terrifically high volume of jobs left unfilled. Published in 2019, the gap they identified looked like this:

  • Nearly 500,000 jobs unfilled in the U.S.
  • Globally, a gap of 4 million jobs was reported.
  • 65% of the respondents say they’re short on cybersecurity staff.

Needless to say, there’s opportunity in the field for both technical and non-technical roles.

Here’s an important thing to keep in mind about cybersecurity:, it’s not solely about understanding technology. It’s about understanding people too and how people and technology interact.

The moment you see cybersecurity through that broader lens, you can see how the field opens widely to encompass a range of roles. Of course, there are analysts and engineers, yet it also includes other roles like digital forensics and cyber investigation, healthcare information security, cryptography, and even cyber law. Additionally, there’s needed expertise in the realms of privacy, governance, ethics, and even digital ethics. And if you take a role with a security company such as ours, the opportunity further extends to positions in account management, marketing, and operations. (In fact, you can drop by our careers page for a look at our current openings and what workday life is like around here.)

Why now’s a great time to consider a cybersecurity career

There are plenty of reasons. Above that data published in 2019, our unprecedented reliance on the internet to work, learn, and stay connected in 2020, demand for cybersecurity jobs is yet more so on the rise. As so many of us turned increasingly to the internet to get through our day, the same is true for hackers and crooks.

With that, let’s take a quick look at several of the factors working in your favor as you consider a change.

There’s demand for cybersecurity jobs.

We’ve all seen the news stories of major breaches at big retailers, credit reporting agencies, hotels, and even healthcare providers. It’s not just the private sector that’s been grappling with cybersecurity concerns, there’s need in the public sector as well—like municipalities. In all, every organization needs cybersecurity (just as we all need cybersecurity for our homes), and thus there’s plenty of opportunity out there. Using just one of the many possible cybersecurity roles as an example, the U.S. Bureau of Labor Statistics predicts a 32% increase in demand for information security analysts through 2028—which is far higher than the average of other professions.

You don’t need a specific degree in cybersecurity to get a job.

In fact, the same (ICS)2 survey discovered that only 42% of current cybersecurity pros said that their first job after higher education was in the field of cybersecurity. In other words, the majority of cybersecurity pros ended up that way by some means of career shift or change. And they got there through certifications and training rather than by way of a degree from a college or university.

Transferrable skills absolutely apply.

Our own Chief Human Resources Officer, Chatelle Lynch, put it quite well in an interview with Business Insider just a few weeks ago: “It’s no secret that the demand for cybersecurity staff has steadily grown over the past decade,” she says. “This means opportunity, so if you don’t have a degree, don’t let that slow you down. You may have unique work experience or relevant certifications, alternative learning, or transferable skills that you need to make sure you highlight when applying and interviewing.”

For example, she goes on to say that prior military service, IT experience, and volunteer or hobbyist activities (even online gaming) are a good foundation for cybersecurity roles.

Cybersecurity employers seek candidates with non-technical soft skills.

These skills absolutely apply, and they’re sought after skills as well. The ability to work independently, lead projects, write and document well, and particularly strong people skills are vital for a role where you’ll be interfacing with numerous individuals, departments, and business units. Likewise, as called out above, certain roles focus more on the non-technical side of security solutions.

Getting trained in cybersecurity

The beauty of making a career change to cybersecurity is that there are plenty of ways you can get it done at home and on your time.

If you’re just getting started, you can test the waters for free or at relatively low cost with a Massively Open Online Course (MOOC) that gives you the basics on cybersecurity. Future Learn’s “Introduction to Cybersecurity”  from The Open University is one example of an intro program, as is the University of Michigan’s “Securing Digital Democracy” class that’s offered through Coursera.

If you’re already an IT pro or have a strong technical background, there are similar MOOC courses available that cater to your current level of knowledge and skill. The University of Maryland’s “Cybersecurity Specialization” and “Usable Security” are geared accordingly.

For a list of cybersecurity programs available online, drop by CyberDegrees.org. Their listing is one of many good places to start.

Other free and low-cost avenues out there include subscribing to some security bloggers, grabbing some hands-on work with coding and IT networking fundamentals from online learning companies like Udemy, Codecademy, and Khan Academy, or joining some online cybersecurity groups for a little professional networking. In all, there’s plenty of opportunity to learn from others, both in structured class settings and in more unstructured peer and mentorship relationships.

Prepare for that online interview

When you’re ready to start your job search, there’s a good chance that your interview will be conducted online. Online interviews have been part of the job-hunting landscape for a few years now, yet with many employers enacting work from home measures, it’s the way hiring gets done right now. I expect this to continue, as employers have embraced its many benefits, particularly in the early stages of interviews. If the prospect of an online interview is new to you, I put together a pair of articles this spring that can help.

Your cybersecurity career

As you make the jump, here’s the most important thing you’ll need: a love of technology and a desire to protect the people who use it. If you can combine a drive to understand both technology and people better with the further drive to see it all through, you’ll be well on your way. Like any career shift or change, there’s work ahead, yet it’s my impression that our field is a welcoming and supportive one—and very much on a keen lookout for new talent.
