Summary
This detection rule identifies the execution of the `touch` command on Linux systems, specifically when used with the `-r` flag. This flag modifies the timestamp of a file based on another file's timestamp. The rule is particularly concerned with specific VMware-related paths, such as `/etc/vmware/`, `/usr/lib/vmware/`, and any paths under `/vmfs/*`. The presence of these paths in the command arguments may signal that a threat actor is attempting to tamper with timestamps of VMware files, potentially to obscure unauthorized modifications or activities. The rule uses EQL (Event Query Language) to monitor relevant logs for instances of the `touch` command that match these criteria, contributing to the defense against potential attacks targeting virtual machine environments.
