The APT group DefrayX seems to have launched a brand new model of its RansomExx malware, rewritten within the Rust programming language — probably to keep away from detection by antivirus software program.
Based on IBM Safety X-Drive Menace researchers, that evasion could also be profitable, a minimum of for now. IBM reported that one pattern that it analyzed “was not detected as malicious within the VirusTotal platform for a minimum of 2 weeks after its preliminary submission” and that “the brand new pattern remains to be solely detected by 14 out of the 60+ AV suppliers represented within the platform.”
Moreover being more durable to detect and reverse-engineer, Rust has the benefit of being platform-agnostic. Thus, whereas the brand new model of RansomExx runs on Linux, IBM predicts a Home windows model shall be on its method quickly, if it is not already unfastened and undetected.
RansomExx is much from the one malware package deal written in Rust. BlackCat, Hive, and, earlier than that, Buer are outstanding examples of malware that was rewritten to keep away from detection based mostly on the C/C++ variations.
DefrayX is thought for its assaults concentrating on cloud workloads and particular verticals, together with healthcare and manufacturing.
