    Linux Version of RTM Locker Ransomware Targets VMware ESXi Servers

    In a new report by Uptycs, researchers analyzed a Linux variant of the RTM Locker that is based on the leaked source code of the now-defunct Babuk ransomware. The RTM Locker Linux encryptor appears to be created explicitly for attacking VMware ESXi systems, as it contains numerous references to commands used to manage virtual machines. When launched, the encryptor will first attempt to encrypt all VMware ESXi virtual machines by first gathering a list of running VMs. The encryptor then terminates all running virtual machines and starts to encrypt files that have the following file extensions - .log (log files), .vmdk (virtual disks), .vmem (virtual machine memory), .vswp (swap files), and .vmsn (VM snapshots). All of these files are associated with virtual machines running on VMware ESXi. Like Babuk, RTM uses a random number generation and ECDH on Curve25519 for asymmetric encryption, but instead of Sosemanuk, it relies on ChaCha20 for symmetric encryption.

ARES Group manages its own site with database leaks and a forum, which may fill the void left by the now defunct Breached forum.

    Microsoft Gets Court Order to Sinkhole Cobalt Strike Traffic

    A common thread in ransomware incidents is hackers' use of penetration testing tool Cobalt Strike. U.S. federal agencies have issued repeated warnings, particularly to the health sector, to be vigilant for its presence. Google in late 2022 released code allowing antivirus engines to detect it. Now, Cobalt Strike maker Fortra, Microsoft and the Health Information Sharing and Analysis Center have obtained a U.S. federal court order redirecting into sinkhole servers the internet traffic from Cobalt Strike-infected computers sent to command-and-control centers controlled by bad actors. The order affects server internet protocol addresses hosted by data centers across the United States and a slew of malicious domains. "Instead of disrupting the command and control of a malware family, this time we are working with Fortra to remove illegal legacy copies of Cobalt Strike so they can no longer be used by cybercriminals, said Amy Hogan-Burney, general manager of Microsoft's Digital Crimes Unit. A complaint filed in the U.S. District Court for the Eastern District of New York by the three plaintiffs details a history of unlicensed versions of Cobalt Strike being used by hackers to pave the way for ransomware attacks by the likes of LockBit and Conti and its many spinoff groups.

    Iran-linked MERCURY APT Behind Destructive Attacks on Hybrid Environments

    Law Enforcement Lures Cybercriminals With Fake DDoS Services

    ow many sites the NCA is running and what it offers aren't exactly clear - a ploy at the heart of this newly disclosed effort, part of Operation PowerOff. Authorities say it's designed to sow confusion and doubt and undermine trust in the criminal market. Paranoia, they hope, runs deep. Call it an escalation in the never-ending fight against booter sites, which allow individuals with little technical ability to easily commit cybercrimes. "Booter/stresser services are like grass: You can mow the lawn, but the grass will grow back," Daniel Smith, head of research for cybersecurity firm Radware's threat intelligence division, said. "The problem with enforcement is the reaction. As law enforcement worldwide steps up their efforts to reduce crime, the criminals will escalate in lockstep, as there is too much profit involved in cybercrime for everyone to be scared away." Fostering uncertainty among customers is another way to attempt to reduce the proliferation of booter sites.

    Telegram Now the Go-to Place for Selling Phishing Tools and Services

    Fake Data Theft Proof Leads to Royal Ransomware Outbreak

    The Royal ransomware group - another offshoot of the disbanded Conti group - appears to have targeted over 1,000 organizations with a social engineering attack designed to trick victims into trusting the attackers. The firm last month identified a spam campaign that appears to trace to Royal and that layers on the deception, first by falsely notifying victims that a ransomware group has attacked them and then by pressuring them into opening a file that purportedly lists what was stolen but is a malware loader. The scheme may have even concocted a fake ransomware group: the Midnight Group. The group's claims to have infected victims with ransomware appeared fake. Victims of this fraud campaign receive emails claiming the Midnight Group was behind the original ransomware attack and their data will be posted on the dark web if they do not pay. Midnight is itself a fake scheme likely cooked up by Royal. This assessment is based in part on the attack telemetry and malware used by the attackers and the emails received by victims.
