XHide

ASEC identified a multi-component Linux malware campaign targeting poorly managed SSH servers. The attack chain uses Go-based propagation malware to worm-like spread XMRig CoinMiner across SSH-accessible servers. The XMRig variant implements robust persistence via systemd services, cron jobs, and a /dev/shm watchdog, while XHide and Shc-compiled obfuscation scripts disguise mining activity by spoofing process names and hijacking common administrative commands through .bashrc aliases.
