A Ukrainian security researcher this week leaked several years of internal chat logs and other sensitive data tied to Conti, an aggressive and ruthless Russian cybercrime group that focuses on deploying its ransomware to companies with more than $100 million in annual revenue. The chat logs offer a fascinating glimpse into the challenges of running a sprawling criminal enterprise with more than 100 salaried employees. The records also provide insight into how Conti has dealt with its own internal breaches and attacks from private security firms and foreign governments. Conti’s threatening message this week regarding international interference in Ukraine. Conti makes international news headlines each week when it publishes to its dark web blog new information stolen from ransomware victims who refuse to pay an extortion demand. In response to…

President Biden joined European leaders this week in enacting economic sanctions against Russia in response its military invasion of Ukraine. The West has promised tougher sanctions are coming, but experts warn these will almost certainly trigger a Russian retaliation against America and its allies, which could escalate into cyber attacks on Western financial institutions and energy infrastructure. Michael Daniel is a former cybersecurity advisor to the White House during the Obama administration who now heads the Cyber Threat Alliance, an industry group focused on sharing threat intelligence among members. Daniel said there are two primary types of cyber threats the group is concerned about potentially coming in response to sanctions on Russia. The first involves what Daniel called “spillover and collateral damage” — a global malware contagion akin to a…

Posted by Ard Biesheuvel, Google Open Source Security Team Linux kernel support for the 32-bit ARM architecture was contributed in the late 90s, when there was little corporate involvement in Linux development, and most contributors were students or hobbyists, tinkering with development boards, often without much in the way of documentation. Now 20+ years later, 32-bit ARM's maintainer has downgraded its support level to 'odd fixes,' while remaining active as a kernel contributor. This is a common pattern for aging and obsolete architectures: corporate funding for Linux kernel development has tremendously increased the pace of development, but only for architectures with a high return on investment. As a result, the 32-bit ARM port of Linux is essentially in maintenance-only mode, and lacks core Linux advancements such as THREAD_INFO_IN_TASK or VMAP_STACK, which…

The U.S. Internal Revenue Service (IRS) said Monday that taxpayers are no longer required to provide facial scans to create an account online at irs.gov. In lieu of providing biometric data, taxpayers can now opt for a live video interview with ID.me, the privately-held Virginia company that runs the agency’s identity proofing system. The IRS also said any biometric data already shared with ID.me would be permanently deleted over the next few weeks, and any biometric data provided for new signups will be destroyed after an account is created. “Taxpayers will have the option of verifying their identity during a live, virtual interview with agents; no biometric data – including facial recognition – will be required if taxpayers choose to authenticate their identity through a virtual interview,” the IRS said…

Missouri Governor Mike Parson made headlines last year when he vowed to criminally prosecute a journalist for reporting a security flaw in a state website that exposed personal information of more than 100,000 teachers. But Missouri prosecutors now say they will not pursue charges following revelations that the data had been exposed since 2011 — two years after responsibility for securing the state’s IT systems was centralized within Parson’s own Office of Administration. Missouri Gov. Mike Parson (R), vowing to prosecute the St. Louis Post-Dispatch for reporting a security vulnerability that exposed teacher SSNs. In October 2021, St. Louis Post-Dispatch reporter Josh Renaud alerted Missouri education department officials that their website was exposing the Social Security numbers of more than 100,000 primary and secondary teachers in the state. Renaud found…

A network intrusion at the International Committee for the Red Cross (ICRC) in January led to the theft of personal information on more than 500,000 people receiving assistance from the group. KrebsOnSecurity has learned that the email address used by a cybercriminal actor who offered to sell the stolen ICRC data also was used to register multiple domain names the FBI says are tied to a sprawling media influence operation originating from Iran. On Jan. 19, the ICRC disclosed the compromise of servers hosting the personal information of more than 500,000 people receiving services from the Red Cross and Red Crescent Movement. The ICRC said the hacked servers contained data relating to the organization’s Restoring Family Links services, which works to reconnect people separated by war, violence, migration and other…

In January, KrebsOnSecurity examined clues left behind by “Wazawaka,” the hacker handle chosen by a major ransomware criminal in the Russian-speaking cybercrime scene. Wazawaka has since “lost his mind” according to his erstwhile colleagues, creating a Twitter account to drop exploit code for a widely-used virtual private networking (VPN) appliance, and publishing bizarre selfie videos taunting security researchers and journalists. Wazawaka, a.k.a. Mikhail P. Matveev, a.k.a. “Orange,” a.k.a. “Boriselcin,” showing off his missing ring finger. In last month’s story, we explored clues that led from Wazawaka’s multitude of monikers, email addresses, and passwords to a 30-something father in Abakan, Russia named Mikhail Pavlovich Matveev. This post concerns itself with the other half of Wazawaka’s identities not mentioned in the first story, such as how Wazawaka also ran the Babuk ransomware…

Posted by Eduardo Vela, Vulnerability Matchmaker  Until December 31 2022 we will pay 20,000 to 91,337 USD for exploits of vulnerabilities in the Linux Kernel, Kubernetes, GKE or kCTF that are exploitable on our test lab. We launched an expansion of kCTF VRP on November 1, 2021 in which we paid 31,337 to 50,337 USD to those that are able to compromise our kCTF cluster and obtain a flag. We increased our rewards because we recognized that in order to attract the attention of the community we needed to match our rewards to their expectations. We consider the expansion to have been a success, and because of that we would like to extend it even further to at least until the end of the year (2022). During the last three…

Posted by Sarah Jacobus, Vulnerability Rewards Team  Last year was another record setter for our Vulnerability Reward Programs (VRPs). Throughout 2021, we partnered with the security researcher community to identify and fix thousands of  vulnerabilities – helping keep our users and the internet safe.  Thanks to these incredible researchers, Vulnerability Reward Programs across Google continued to grow, and we are excited to report that in 2021 we awarded a record breaking $8,700,000 in vulnerability rewards – with researchers donating over $300,000 of their rewards to a charity of their choice.  We also launched bughunters.google.com in 2021, a public researcher portal dedicated to keeping Google products and the internet safe and secure. This new platform brings all of our VRPs (Google, Android, Abuse, Chrome, and Google Play) closer together and provides…

Russian authorities have arrested six men accused of operating some of the most active online bazaars for selling stolen payment card data. The crackdown — the second closure of major card fraud shops by Russian authorities in as many weeks — comes closely behind Russia’s arrest of 14 alleged affiliates of the REvil ransomware gang, and has many in the cybercrime underground asking who might be next. Dept. K’s message for Trump’s Dumps users. On Feb. 7 and 8, the domains for the carding shops Trump’s Dumps, Ferum Shop, Sky-Fraud and UAS were seized by Department K, a division of the Ministry of Internal Affairs of the Russian Federation that focuses on computer crimes. The websites for the carding stores were retrofitted with a message from Dept. K asking, “Which…
