IRS To Ditch Biometric Requirement for Online Access

February 7, 2022
105 Comments

The Internal Revenue Service (IRS) said today it will be transitioning away from requiring biometric data from taxpayers who wish to access their records at the agency’s website. The reversal comes as privacy experts and lawmakers have been pushing the IRS and other federal agencies to find less intrusive methods for validating one’s identity with the U.S. government online.

Late last year, the login page for the IRS was updated with text advising that by the summer of 2022, the only way for taxpayers to access their records at irs.gov will be through ID.me, an online identity verification service that collects biometric data — such as live facial scans using a mobile device or webcam.

The IRS first announced its partnership with ID.me in November, but the press release received virtually no attention. On Jan. 19, KrebsOnSecurity published the story IRS Will Soon Require Selfies for Online Access, detailing a rocky experience signing up for IRS access via ID.me. That story immediately went viral, bringing this site an almost unprecedented amount of traffic. A tweet about it quickly garnered more than two million impressions.

It was clear most readers had no idea these new and more invasive requirements were being put in place at the IRS and other federal agencies (the Social Security Administration also is steering new signups to ID.me).

ID.me says it has approximately 64 million users, with 145,000 new users signing up each day. Still, the bulk of those users are people who have been forced to sign up with ID.me as a condition of receiving state or federal financial assistance, such as unemployment insurance, child tax credit payments, and pandemic assistance funds.

In the face of COVID, dozens of states collectively lost tens of billions of dollars at the hands of identity thieves impersonating out-of-work Americans seeking unemployment insurance. Some 30 states and 10 federal agencies now use ID.me to screen for ID thieves applying for benefits in someone else’s name.

But ID.me has been problematic for many legitimate applicants who saw benefits denied or delayed because they couldn’t complete ID.me’s verification process.  Critics charged the IRS’s plan would unfairly disadvantage people with disabilities or limited access to technology or Internet, and that facial recognition systems tend to be less accurate for people with darker skin.

Many readers were aghast that the IRS would ask people to hand over their biometric and personal data to a private company that begin in 2010 as a way to help veterans, teachers and other public servants qualify for retail discounts. These readers had reasonable questions: Who has (or will have) access to this data? Why should it be stored indefinitely (post-verification)? What happens if ID.me gets breached?

The Washington Post reported today that in a meeting with lawmakers, IRS officials said they were considering another identity verification option that wouldn’t use facial recognition. At the same time, Senate Finance Committee Chairman Ron Wyden (D-Ore.) challenged the Treasury Department and IRS to reconsider the biometric requirements.

In a statement published today, the IRS said it was transitioning away from using a third-party service for facial recognition to help authenticate people creating new online accounts.

“The transition will occur over the coming weeks in order to prevent larger disruptions to taxpayers during filing season,” the IRS said. “During the transition, the IRS will quickly develop and bring online an additional authentication process that does not involve facial recognition. The IRS will also continue to work with its cross-government partners to develop authentication methods that protect taxpayer data and ensure broad access to online tools.” Continue reading →

How Phishers Are Slinking Their Links Into LinkedIn

February 3, 2022
24 Comments

If you received a link to LinkedIn.com via email, SMS or instant message, would you click it? Spammers, phishers and other ne’er-do-wells are hoping you will, because they’ve long taken advantage of a marketing feature on the business networking site which lets them create a LinkedIn.com link that bounces your browser to other websites, such as phishing pages that mimic top online brands (but chiefly Linkedin’s parent firm Microsoft).

At issue is a “redirect” feature available to businesses that chose to market through LinkedIn.com. The LinkedIn redirect links allow customers to track the performance of ad campaigns, while promoting off-site resources. These links or “Slinks” all have a standard format: “https://www.linkedin.com/slink?code=” followed by a short alphanumeric variable.

Here’s the very first Slink created: http://www.linkedin.com/slink?code=1, which redirects to the homepage for LinkedIn Marketing Solutions.

The trouble is, there’s little to stop criminals from leveraging newly registered or hacked LinkedIn business accounts to create their own ad campaigns using Slinks. Urlscan.io, a free service that provides detailed reports on any scanned URLs, also offers a historical look at suspicious links submitted by other users. This search via Urlscan reveals dozens of recent phishing attacks that have leveraged the Slinks feature.

Here’s one example from Jan. 31 that uses Linkedin.com links to redirect anyone who clicks to a site that spoofs Adobe, and then prompts users to log in to their Microsoft email account to view a shared document.

Urlscan also found this phishing scam from Jan. 12 that uses Slinks to spoof the U.S. Internal Revenue Service. Here’s a Feb. 3 example that leads to a phish targeting Amazon customers. This Nov. 26 sample from Urlscan shows a LinkedIn link redirecting to a Paypal phishing page. Continue reading →

Fake Investor John Bernard Sinks Norwegian Green Shipping Dreams

January 29, 2022
38 Comments

Several articles here have delved into the history of John Bernard, the pseudonym used by a fake billionaire technology investor who tricked dozens of startups into giving him tens of millions of dollars. Bernard’s latest victim — a Norwegian company hoping to build a fleet of environmentally friendly shipping vessels — is now embroiled in a lawsuit over a deal gone bad, in which Bernard falsely claimed to have secured $100 million from six other wealthy investors, including the founder of Uber and the artist Abel Makkonen Tesfaye, better known as The Weeknd.

John Bernard is a pseudonym used by John Clifton Davies, a convicted fraudster from the United Kingdom who is currently a fugitive from justice and residing in Ukraine. Davies’ Bernard persona has fleeced dozens of technology companies out of an estimated $30 million with the promise of lucrative investments.

For several years until reinventing himself again quite recently, Bernard pretended to be a billionaire Swiss investor who made his fortunes in the dot-com boom 20 years ago and who was seeking investment opportunities. Bernard generated a stream of victims by offering extraordinarily generous finder’s fees for investment brokers who helped him secure new clients. But those brokers would eventually get stiffed as well because Bernard’s company would never consummate a deal.

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

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

But Bernard would adopt a slightly different approach to stealing from Freidig Shipping Ltd., a Norwegian company formed in 2017 that was seeking the equivalent of USD $100 million investment to bring its green fleet of 30 new offshore service vessels to fruition.

Journalists Harald Vanvik and Harald Berglihn from the Norwegian Business Daily write that through investment advisors in London, Bernard was introduced to Nils-Odd Tønnevold, co-founder of Freidig Shipping and an investment advisor with 20 years of experience.

“Both Bernard and Inside Knowledge appeared to be professionals,” the reporters wrote in a story that’s behind a paywall. “Bernard appeared to be experienced. He knew a lot about start-ups and got into things quickly. Credible and reliable was the impression of him, said Tønnevold.”

“Bernard eventually took on the role of principal investor, claiming he had six other wealthy investors on the team, including artist Abel Makkonen Tesfaye, known as The Weeknd, Uber founder Garrett Camp and Norilsk Nickel owner Russian Vladimir Potanin,” the Norwegian journalists wrote. “These committed to contribute $99.25 million to Freidig.”

So in this case Bernard conveniently claimed he’d come up with almost all of the investment, which came $750,000 short of the goal. Another investor, a Belgian named Guy Devos, contributed the remaining $750,000.

But by the spring of 2020, it was clear that Devos and others involved in the shipping project had been tricked, and that all the money which had been paid to Bernard — an estimated NOK 15 million (~USD $1.67 million) — had been lost. By that time the two co-founders and their families had borrowed USD $1.5 million, and had transferred the funds to Inside Knowledge. Continue reading →

Who Wrote the ALPHV/BlackCat Ransomware Strain?

January 28, 2022
16 Comments

In December 2021, researchers discovered a new ransomware-as-a-service named ALPHV (a.k.a. “BlackCat“), considered to be the first professional cybercrime group to create and use a ransomware strain written in the Rust programming language. In this post, we’ll explore some of the clues left behind by a developer who was reputedly hired to code the ransomware variant.

Image: Varonis.

According to an analysis released this week by Varonis, ALPHV is actively recruiting operators from several ransomware organizations — including REvil, BlackMatter and DarkSide — and is offering affiliates up to 90 percent of any ransom paid by a victim organization.

“The group’s leak site, active since early December 2021, has named over twenty victim organizations as of late January 2022, though the total number of victims, including those that have paid a ransom to avoid exposure, is likely greater,” Varonis’s Jason Hill wrote.

One concern about more malware shifting to Rust is that it is considered a much more secure programming language compared to C and C++, writes Catalin Cimpanu for The Record. The upshot? Security defenders are constantly looking for coding weaknesses in many ransomware strains, and if more start moving to Rust it could become more difficult to find those soft spots.

Researchers at Recorded Future say they believe the ALPHV/BlackCat author was previously involved with the infamous REvil ransomware cartel in some capacity. Earlier this month the Russian government announced that at the United States’ request it arrested 14 individuals in Russia thought to be REvil operators.

Still, REvil rolls on despite these actions, according to Paul Roberts at ReversingLabs. “The recent arrests have NOT led to a noticeable change in detections of REvil malicious files,” Roberts wrote. “In fact, detections of files and other software modules associated with the REvil ransomware increased modestly in the week following the arrests by Russia’s FSB intelligence service.”

Meanwhile, the U.S. State Department has a standing $10 million reward for information leading to the identification or location of any individuals holding key leadership positions in REvil.

WHO IS BINRS?

A confidential source recently had a private conversation with a support representative who fields questions and inquiries on several cybercrime forums on behalf of a large and popular ransomware affiliate program. The affiliate rep confirmed that a coder for ALPHV was known by the handle “Binrs” on multiple Russian-language forums.

On the cybercrime forum RAMP, the user Binrs says they are a Rust developer who’s been coding for 6 years. “My stack is Rust, nodejs, php, golang,” Binrs said in an introductory post, in which they claim to be fluent in English. Binrs then signs the post with their identification number for ToX, a peer-to-peer instant messaging service.

That same ToX ID was claimed by a user called “smiseo” on the Russian forum BHF, in which smiseo advertises “clipper” malware written in Rust that swaps in the attacker’s bitcoin address when the victim copies a cryptocurrency address to their computer’s temporary clipboard.

The nickname “YBCat” advertised that same ToX ID on Carder[.]uk, where this user claimed ownership over the Telegram account @CookieDays, and said they could be hired to do software and bot development “of any level of complexity.” YBCat mostly sold “installs,” offering paying customers to ability to load malware of their choice on thousands of hacked computers simultaneously.

There is also an active user named Binrs on the Russian crime forum wwh-club[.]co who says they’re a Rust coder who can be reached at the @CookieDays Telegram account.

On the Russian forum Lolzteam, a member with the username “DuckerMan” uses the @CookieDays Telegram account in his signature. In one thread, DuckerMan promotes an affiliate program called CookieDays that lets people make money by getting others to install cryptomining programs that are infected with malware. In another thread, DuckerMan is selling a different clipboard hijacking program called Chloe Clipper.

The CookieDays moneymaking program.

According to threat intelligence firm Flashpoint, the Telegram user DuckerMan employed another alias — Sergey Duck. These accounts were most active in the Telegram channels “Bank Accounts Selling,” “Malware developers community,” and “Raidforums,” a popular English-language cybercrime forum. Continue reading →

Scary Fraud Ensues When ID Theft & Usury Collide

January 25, 2022
62 Comments

What’s worse than finding out that identity thieves took out a 546 percent interest payday loan in your name? How about a 900 percent interest loan? Or how about not learning of the fraudulent loan until it gets handed off to collection agents? One reader’s nightmare experience spotlights what can happen when ID thieves and hackers start targeting online payday lenders.

The reader who shared this story (and copious documentation to go with it) asked to have his real name omitted to avoid encouraging further attacks against his identity. So we’ll just call him “Jim.” Last May, someone applied for some type of loan in Jim’s name. The request was likely sent to an online portal that takes the borrower’s loan application details and shares them with multiple prospective lenders, because Jim said over the next few days he received dozens of emails and calls from lenders wanting to approve him for a loan.

Many of these lenders were eager to give Jim money because they were charging exorbitant 500-900 percent interest rates for their loans. But Jim has long had a security freeze on his credit file with the three major consumer credit reporting bureaus, and none of the lenders seemed willing to proceed without at least a peek at his credit history.

Among the companies that checked to see if Jim still wanted that loan he never applied for last May was Mountain Summit Financial (MSF), a lending institution owned by a Native American tribe in California called the Habematelol Pomo of Upper Lake.

Jim told MSF and others who called or emailed that identity thieves had applied for the funds using his name and information; that he would never take out a payday loan; and would they please remove his information from their database? Jim says MSF assured him it would, and the loan was never issued.

Jim spent months sorting out that mess with MSF and other potential lenders, but after a while the inquiries died down. Then on Nov. 27 — Thanksgiving Day weekend — Jim got a series of rapid-fire emails from MSF saying they’ve received his loan application, that they’d approved it, and that the funds requested were now available at the bank account specified in his MSF profile.

Curiously, the fraudsters had taken out a loan in Jim’s name with MSF using his real email address — the same email address the fraudsters had used to impersonate him to MSF back in May 2021. Although he didn’t technically have an account with MSF, their authentication system is based on email addresses, so Jim requested that a password reset link be sent to his email address. That worked, and once inside the account Jim could see more about the loan details:

The terms of the unauthorized loan in Jim’s name from MSF.

Take a look at that 546.56 percent interest rate and finance charges listed in this $1,000 loan. If you pay this loan off in a year at the suggested bi-weekly payment amounts, you will have paid $3,903.57 for that $1,000.

Jim contacted MSF as soon as they opened the following week and found out the money had already been dispersed to a Bank of America account Jim didn’t recognize. MSF had Jim fill out an affidavit claiming the loan was the result of identity theft, which necessitated filing a report with the local police and a number of other steps. Jim said numerous calls to Bank of America’s fraud team went nowhere because they refused to discuss an account that was not in his name.

Jim said MSF ultimately agreed that the loan wasn’t legitimate, but they couldn’t or wouldn’t tell him how his information got pushed through to a loan — even though MSF was never able to pull his credit file.

Then in mid-January, Jim heard from MSF via snail mail that they’d discovered a data breach.

“We believe the outsider may have had an opportunity to access the accounts of certain customers, including your account, at which point they would be able to view personal information pertaining to that customer and potentially obtain an unauthorized loan using the customer’s credentials,” MSF said.

MSF said the personal information involved in this incident may have included name, date of birth, government-issued identification numbers (e.g., SSN or DLN), bank account number and routing number, home address, email address, phone number and other general loan information.

A portion of the Jan. 14, 2022 breach notification letter from tribal lender Mountain Summit Financial.

Nevermind that his information was only in MSF’s system because of an earlier attempt by ID thieves: The intruders were able to update his existing (never-deleted) record with new banking information and then push the application through MSF’s systems.

“MSF was the target of a suspected third-party attack,” the company said, noting that it was working with the FBI, the California Sheriff’s Office, and the Tribal Commission for Lake County, Calif.  “Ultimately, MSF confirmed that these trends were part of an attack that originated outside of the company.”

MSF has not responded to questions about the aforementioned third party or parties that may be involved. But it is possible that other tribal lenders could have been affected: Jim said that not long after the phony MSF payday loan was pushed through, he received at least three inquiries in rapid succession from other lenders who were all of a sudden interested in offering him a loan.

In a statement sent to KrebsOnSecurity, MSF said it was “the victim of a malicious attack that originated outside of the company, by unknown perpetrators.”

“As soon as the issue was uncovered, the company initiated cybersecurity incident response measures to protect and secure its information; and notified law enforcement and regulators,” MSF wrote. “Additionally, the company has notified individuals whose personal identifiable information may have been impacted by this crime and is actively working with law enforcement in its investigation. As this is an ongoing criminal investigation, we can make no additional comment at this time.”

According to the Native American Financial Services Association (NAFSA), a trade group in Washington, D.C. representing tribal lenders, the short-term installment loan products offered by NAFSA members are not payday loans but rather “installment loans” — which are amortized, have a definite loan term, and require payments that go toward not just interest, but that also pay down the loan principal.

NAFSA did not respond to multiple requests for comment.

Nearly all U.S. states have usury laws that limit the amount of interest a company can charge on a loan, but those limits traditionally haven’t applied to tribal lenders. Continue reading →

Crime Shop Sells Hacked Logins to Other Crime Shops

January 21, 2022

Up for the “Most Meta Cybercrime Offering” award this year is Accountz Club, a new cybercrime store that sells access to purloined accounts at services built for cybercriminals, including shops peddling stolen payment cards and identities, spamming tools, email and phone bombing services, and those selling authentication cookies for a slew of popular websites.

Criminals ripping off other crooks is a constant theme in the cybercrime underworld; Accountz Club’s slogan  — “the best autoshop for your favorite shops’ accounts” — just normalizes this activity by making logins stolen from users of various cybercrime shops for sale at a fraction of their account balances.

The site says it sells “cracked” accounts, or those that used passwords which could be easily guessed or enumerated by automated tools. All of the credentials being sold by Accountz provide access to services that in turn sell access to stolen information or hijacked property, as in the case of “bot shops” that resell access to infected computers.

One example is Genesis Market, where customers can search for stolen credentials and authentication cookies from a broad range of popular online destinations. Genesis even offers a custom-made web browser where you can load authentication cookies from botted PCs and waltz right into the account without having to enter a username or password or mess with multi-factor authentication.

Accountz is currently selling four different Genesis logins for about 40-50 percent of their unspent balances. Genesis mostly gets its inventory of botted computers and stolen logins from resellers who specialize in deploying infostealer malware via email and booby-trapped websites. Likewise, it appears Accountz also derives much of its stock from a handful of resellers, who presumably are the same ones doing the cybercrime service account cracking.

The Genesis bot shop.

In essence, Accountz customers are paying for illicit access to cybercrime services that sell access to compromised resources that can be abused for cybercrime. That’s seriously meta. Continue reading →

IRS Will Soon Require Selfies for Online Access

January 19, 2022
335 Comments

If you created an online account to manage your tax records with the U.S. Internal Revenue Service (IRS), those login credentials will cease to work later this year. The agency says that by the summer of 2022, the only way to log in to irs.gov will be through ID.me, an online identity verification service that requires applicants to submit copies of bills and identity documents, as well as a live video feed of their faces via a mobile device.

The IRS says it will require ID.me for all logins later this summer.

McLean, Va.-based ID.me was originally launched in 2010 with the goal of helping e-commerce sites validate the identities of customers who might be eligible for discounts at various retail establishments, such as veterans, teachers, students, nurses and first responders.

These days, ID.me is perhaps better known as the online identity verification service that many states now use to help stanch the loss of billions of dollars in unemployment insurance and pandemic assistance stolen each year by identity thieves. The privately-held company says it has approximately 64 million users, and gains roughly 145,000 new users each day.

Some 27 states already use ID.me to screen for identity thieves applying for benefits in someone else’s name, and now the IRS is joining them. The service requires applicants to supply a great deal more information than typically requested for online verification schemes, such as scans of their driver’s license or other government-issued ID, copies of utility or insurance bills, and details about their mobile phone service.

When an applicant doesn’t have one or more of the above — or if something about their application triggers potential fraud flags — ID.me may require a recorded, live video chat with the person applying for benefits.

Since my credentials at the IRS will soon no longer work, I opted to create an ID.me account and share the experience here. An important preface to this walk-through is that verifying one’s self with Id.me requires one to be able to take a live, video selfie — either with the camera on a mobile device or a webcam attached to a computer (your webcam must be able to open on the device you’re using to apply for the ID.me account).

Update, Feb.7, 2022, 10:21 p.m. ET: The IRS said today it is transitioning away from requiring face biometric data to identify taxpayers. Read more here: IRS To Ditch Biometric Requirement for Online Access.

At Request of U.S., Russia Rounds Up 14 REvil Ransomware Affiliates

January 14, 2022
54 Comments

The Russian government said today it arrested 14 people accused of working for “REvil,” a particularly aggressive ransomware group that has extorted hundreds of millions of dollars from victim organizations. The Russian Federal Security Service (FSB) said the actions were taken in response to a request from U.S. officials, but many experts believe the crackdown is part of an effort to reduce tensions over Russian President Vladimir Putin’s decision to station 100,000 troops along the nation’s border with Ukraine.

The FSB said it arrested 14 REvil ransomware members, and searched more than two dozen addresses in Moscow, St. Petersburg, Leningrad and Lipetsk. As part of the raids, the FSB seized more than $600,000 US dollars, 426 million rubles (~$USD 5.5 million), 500,000 euros, and 20 “premium cars” purchased with funds obtained from cybercrime.

“The search activities were based on the appeal of the US authorities, who reported on the leader of the criminal community and his involvement in encroaching on the information resources of foreign high-tech companies by introducing malicious software, encrypting information and extorting money for its decryption,” the FSB said. “Representatives of the US competent authorities have been informed about the results of the operation.”

The FSB did not release the names of any of the individuals arrested, although a report from the Russian news agency TASS mentions two defendants: Roman Gennadyevich Muromsky, and Andrey Sergeevich Bessonov. Russian media outlet RIA Novosti released video footage from some of the raids:

REvil is widely thought to be a reincarnation of GandCrab, a Russian-language ransomware affiliate program that bragged of stealing more than $2 billion when it closed up shop in the summer of 2019. For roughly the next two years, REvil’s “Happy Blog” would churn out press releases naming and shaming dozens of new victims each week. A February 2021 analysis from researchers at IBM found the REvil gang earned more than $120 million in 2020 alone.

But all that changed last summer, when REvil associates working with another ransomware group — DarkSide — attacked Colonial Pipeline, causing fuel shortages and price spikes across the United States. Just months later, a multi-country law enforcement operation allowed investigators to hack into the REvil gang’s operations and force the group offline.

In November 2021, Europol announced it arrested seven REvil affliates who collectively made more than $230 million worth of ransom demands since 2019. At the same time, U.S. authorities unsealed two indictments against a pair of accused REvil cybercriminals, which referred to the men as “REvil Affiliate #22” and “REvil Affiliate #23.”

It is clear that U.S. authorities have known for some time the real names of REvil’s top captains and moneymakers. Last fall, President Biden told Putin that he expects Russia to act when the United States shares information on specific Russians involved in ransomware activity.

So why now? Russia has amassed approximately 100,000 troops along its southern border with Ukraine, and diplomatic efforts to defuse the situation have reportedly broken down. The Washington Post and other media outlets today report that the Biden administration has accused Moscow of sending saboteurs into Eastern Ukraine to stage an incident that could give Putin a pretext for ordering an invasion.

“The most interesting thing about these arrests is the timing,” said Kevin Breen, director of threat research at Immersive Labs. “For years, Russian Government policy on cybercriminals has been less than proactive to say the least. With Russia and the US currently at the diplomatic table, these arrests are likely part of a far wider, multi-layered, political negotiation.”

President Biden has warned that Russia can expect severe sanctions should it choose to invade Ukraine. But Putin in turn has said such sanctions could cause a complete break in diplomatic relations between the two countries.

Dmitri Alperovitch, co-founder of and former chief technology officer for the security firm CrowdStrike, called the REvil arrests in Russia “ransomware diplomacy.”

“This is Russian ransomware diplomacy,” Alperovitch said on Twitter. “It is a signal to the United States — if you don’t enact severe sanctions against us for invasion of Ukraine, we will continue to cooperate with you on ransomware investigations.”

The REvil arrests were announced as many government websites in Ukraine were defaced by hackers with an ominous message warning Ukrainians that their personal data was being uploaded to the Internet. “Be afraid and expect the worst,” the message warned. Continue reading →

Who is the Network Access Broker ‘Wazawaka?’

January 12, 2022
19 Comments

In a great many ransomware attacks, the criminals who pillage the victim’s network are not the same crooks who gained the initial access to the victim organization. More commonly, the infected PC or stolen VPN credentials the gang used to break in were purchased from a cybercriminal middleman known as an initial access broker. This post examines some of the clues left behind by “Wazawaka,” the hacker handle chosen by a major access broker in the Russian-speaking cybercrime scene.

Wazawaka has been a highly active member of multiple cybercrime forums over the past decade, but his favorite is the Russian-language community Exploit. Wazawaka spent his early days on Exploit and other forums selling distributed denial-of-service (DDoS) attacks that could knock websites offline for about USD $80 a day. But in more recent years, Wazawaka has focused on peddling access to organizations and to databases stolen from hacked companies.

“Come, rob, and get dough!,” reads a thread started by Wazawaka on Exploit in March 2020, in which he sold access to a Chinese company with more than $10 billion in annual revenues. “Show them who is boss.”

According to their posts on Exploit, Wazawaka has worked with at least two different ransomware affiliate programs, including LockBit. Wazawaka said LockBit had paid him roughly $500,000 in commissions for the six months leading up to September 2020.

Wazawaka also said he’d teamed up with DarkSide, the ransomware affiliate group responsible for the six-day outage at Colonial Pipeline last year that caused nationwide fuel shortages and price spikes. The U.S. Department of State has since offered a $5 million reward for information leading to the arrest and conviction of any DarkSide affiliates.

Wazawaka seems to have adopted the uniquely communitarian view that when organizations being held for ransom decline to cooperate or pay up, any data stolen from the victim should be published on the Russian cybercrime forums for all to plunder — not privately sold to the highest bidder. In thread after thread on the crime forum XSS, Wazawaka’s alias “Uhodiransomwar” can be seen posting download links to databases from companies that have refused to negotiate after five days.

“The only and the main principle of ransomware is: the information that you steal should never be sold,” Uhodiransomwar wrote in August 2020. “The community needs to receive it absolutely free of charge if the ransom isn’t paid by the side that this information is stolen from.”

Wazawaka hasn’t always been so friendly to other cybercrooks. Over the past ten years, his contact information has been used to register numerous phishing domains intended to siphon credentials from people trying to transact on various dark web marketplaces. In 2018, Wazawaka registered a slew of domains spoofing the real domain for the Hydra dark web market. In 2014, Wazawaka confided to another crime forum member via private message that he made good money stealing accounts from drug dealers on these marketplaces.

“I used to steal their QIWI accounts with up to $500k in them,” Wazawaka recalled. “A dealer would never go to the cops and tell them he was selling stuff online and someone stole his money.” Continue reading →

‘Wormable’ Flaw Leads January 2022 Patch Tuesday

January 11, 2022
23 Comments

Microsoft today released updates to plug nearly 120 security holes in Windows and supported software. Six of the vulnerabilities were publicly detailed already, potentially giving attackers a head start in figuring out how to exploit them in unpatched systems. More concerning, Microsoft warns that one of the flaws fixed this month is “wormable,” meaning no human interaction would be required for an attack to spread from one vulnerable Windows box to another.

Nine of the vulnerabilities fixed in this month’s Patch Tuesday received Microsoft’s “critical” rating, meaning malware or miscreants can exploit them to gain remote access to vulnerable Windows systems through no help from the user.

By all accounts, the most severe flaw addressed today is CVE-2022-21907, a critical, remote code execution flaw in the “HTTP Protocol Stack.” Microsoft says the flaw affects Windows 10 and Windows 11, as well as Server 2019 and Server 2022.

“While this is definitely more server-centric, remember that Windows clients can also run http.sys, so all affected versions are affected by this bug,” said Dustin Childs from Trend Micro’s Zero Day Initiative. “Test and deploy this patch quickly.”

Quickly indeed. In May 2021, Microsoft patched a similarly critical and wormable vulnerability in the HTTP Protocol Stack; less than a week later, computer code made to exploit the flaw was posted online.

Microsoft also fixed three more remote code execution flaws in Exchange Server, a technology that hundreds of thousands of organizations worldwide use to manage their email. Exchange flaws are a major target of malicious hackers. Almost a year ago, hundreds of thousands of Exchange servers worldwide were compromised by malware after attackers started mass-exploiting four zero-day flaws in Exchange.

Microsoft says the limiting factor with these three newly found Exchange flaws is that an attacker would need to be tied to the target’s network somehow to exploit them. But Satnam Narang at Tenable notes Microsoft has labeled all three Exchange flaws as “exploitation more likely.”

“One of the flaws, CVE-2022-21846, was disclosed to Microsoft by the National Security Agency,” Narang said. “Despite the rating, Microsoft notes the attack vector is adjacent, meaning exploitation will require more legwork for an attacker, unlike the ProxyLogon and ProxyShell vulnerabilities which were remotely exploitable.” Continue reading →
