Organizations running sophisticated virtual networks with VMware’s vSphere service are actively being targeted by cryptojackers, who have figured out how to inject the XMRig commercial cryptominer into the environment, undetected.
Uptycs’ Siddharth Sharma has released research showing threat actors are using malicious shell scripts to make modifications and run the cryptominer on vSphere virtual networks.
The report said the rootkit gets saved as “Libload.so” and the script modifies vSphere to run the XMRig cryptominer.
VMware services have been beleaguered by recent security issues.
Sharma advises security teams running VMware services to look for unusual network activity to detect the cryptominer, as well as other attacks.
“In the past we have seen highly sophisticated groups targeting vulnerable VMware services,” Sharma said.
