Researchers from Akamai say the risk actor behind cryptomining software program dubbed RedTail due to its redtail hidden file title evinces a deep understanding of cryptomining.

It seems that risk actors function their very own mining swimming pools or pool proxies quite than utilizing public ones. “They are opting for greater control over mining outcomes despite the increased operational and financial costs associated with maintaining a private server,” Akamai researchers stated. The hackers additionally “use the newer RandomX algorithm” for higher effectivity and alter working system configuration to make use of bigger reminiscence blocks – hugepages – to spice up efficiency.

Hackers’ use of personal mining swimming pools mirrors techniques utilized by North Korea’s Lazarus Group, though Akamai would not attribute the hackers to any group. Money-starved North Korea is infamous for for-profit hacking operations that embody a heavy dosage of cryptocurrency theft and different inventive methods to evade sanctions to boost cash (see: US FBI Busts North Korean IT Employee Employment Scams).

After being initially noticed earlier this 12 months, the RedTail malware has advanced to incorporate anti-research methods, making it more difficult for safety researchers to research and mitigate the risk.

Akamai says its operators have been fast to take advantage of the PAN-OS vulnerability tracked as CVE-2024-3400, which permits attackers to create an arbitrary file enabling command execution with root consumer privileges (see: Doubtless State Hackers Exploiting Palo Alto Firewall Zero-Day).

Extra notable targets embody TP-Hyperlink routers, the China-origin content material administration system ThinkPHP and Ivanti Join Safe. Safety researchers warn that superior hackers, together with state-sponsored risk actors, are specializing in edge units resulting from their patchy endpoint detection and proprietary software program that hinders forensic analysis (see: State Hackers’ New Frontier: Community Edge Gadgets).
