Potential Discovery Activity Using Find Command for Permissions
This rule detects the use of the 'find' command on Linux systems with specific permission-related arguments. These arguments are often used by attackers during the discovery phase to locate files with unusual permissions, such as SUID/SGID binaries (-perm -4000, -perm -2000, -perm -u=s, -perm -g=s) which can be exploited for privilege escalation, or world-writable files (-perm 0777, -perm -222, -perm -o w) which could be used for persistence or data modification. It also looks for world-executable files (-perm -o x).
