Summary
This rule detects the creation of Pluggable Authentication Module (PAM) shared object files in unusual directories. Attackers may compile PAM shared object files in temporary directories, to move them to system directories later, potentially allowing them to maintain persistence on a compromised system, or harvest account credentials.
Telemetry
There were 0 hits in telemetry last 90d (with the built-in exclusions in place), with several TPs for the PANIX PAM persistence module.
