This detection rule identifies the execution of the `esxcli` command with the `vm` flag, which is commonly used for managing and retrieving information about virtual machines (VMs) hosted on ESXi servers. The rule specifically looks for command lines that contain the keywords 'vm process' and end with 'list', indicating that the user is attempting to list installed VMs. This activity is noteworthy as unauthorized usage of `esxcli` can be indicative of malicious actors exploring virtual infrastructures for vulnerabilities or conducting reconnaissance during an attack. Given the increasing targeting of ESXi servers by cybercriminals, especially with the rise of ransomware attacks, monitoring such command executions is crucial for maintaining the security of virtualized environments.
