|

This rule monitors for the addition of the cap_setuid+ep or cap_setgid+ep capabilities via setcap. Setuid (Set User ID)
|
|
and setgid (Set Group ID) are Unix-like OS features that enable processes to run with elevated privileges, based on the
|
|
file owner or group. Threat actors can exploit these attributes to achieve persistence by creating malicious binaries,
|
|
allowing them to maintain control over a compromised system with elevated permissions.
