A new Monero cryptomining campaign has been detected in the wild being spread and operating in a manner more consistent with ransomware and other attacks that retain a level of persistence than has been seen before.
Check Point researchers said these mining operations have been on-going since mid-January using two specific trojans, Trojan.Win32.Fsysna and an unnamed variant of a Monero cryptominer. Although the ultimate goal for the malware is to create Monero, the malicious actors behind the attacks are using some very “non cryptomining” tactics and software to accomplish their mission. This includes propagation and persistence.
“The highlight of this variant is the use of legitimate IT administration tools, Windows system tools and previously disclosed Windows vulnerabilities in order to infect an entire network of PCs,” wrote Check Point’s Richard Clayton, Check Point’s adding, “The actors behind this campaign possess enough skills and experience to make this a potentially severe attack on any organization with no easy steps for remediation.”
