Security News > 2023 > February > New Wave of Ransomware Attacks Exploiting VMware Bug to Target ESXi Servers

VMware ESXi hypervisors are the target of a new wave of attacks designed to deploy ransomware on compromised systems.

"A malicious actor residing within the same network segment as ESXi who has access to port 427 may be able to trigger the heap-overflow issue in OpenSLP service resulting in remote code execution," the virtualization services provider noted.

French cloud services provider OVHcloud said the attacks are being detected globally with a specific focus on Europe.

It's being suspected that the attacks are related to a new Rust-based ransomware strain called Nevada that emerged on the scene in December 2022.

"Notably, the group behind the Nevada Ransomware is also buying compromised access by themselves, the group has a dedicated team for post-exploitation, and for conducting network intrusions into the targets of interest."

Bleeping Computer reports that the ransom notes seen in the attacks bear no similarities to Nevada ransomware, adding the strain is being tracked under the name ESXiArgs.
