Thousands of machines running Linux have been infected by a malware strain that’s notable for its stealth, the number of misconfigurations it can exploit, and the breadth of malicious activities it can perform, researchers reported Thursday.

The perfctl malware has been targeting vulnerabilities and misconfigurations in millions of Linux systems, likely infecting thousands.

Exploiting a catalog of 20,000 misconfigurations to infect Linux servers, the cryptomining malware has gone largely undetected through use of process masquerading but appears capable of more.

Aqua Nautilus researchers posted a blog post revealing what they know about a specific Linux malware dubbed "Perfctl" that's been targeted at Linux servers over the past three to four years, using "more than 20,

Linux systems are being targeted by a dangerous new malware that can serve as a loader, a proxy, and a cryptocurrency miner. Called Perfctl, the malware was recently spotted by cybersecurity researchers from Aqua Security,
