|
|
This detection rule monitors for the execution of a system command with setuid or setgid capabilities via Python,
|
|
followed by a uid or gid change to the root user. This sequence of events may indicate successful privilege escalation.
|
|
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 escalate privileges to the
|
|
privileges that are set on the binary that is being executed.
