This detection rule identifies the execution of the "mount" command in Linux with the "hidepid=2" parameter. This parameter is used to restrict the visibility of processes to users who are not the owner, effectively hiding processes from other users. When a user employs the mount command with this option, it can be indicative of an attempt to cover tracks or perform malicious activities by limiting access to process information. The rule analyzes the command line arguments associated with the mount command to detect this specific usage, alerting defenders to potentially suspicious behavior.
