Linux Suspicious GCC Invocation Building Init Shared Object

The following analytic detects compiler usage with flags commonly used to create shared libraries that auto-run initialization functions, which are often associated with local privilege escalation exploits.

Detection logic

Detection requirements

Platform: Containers Linux macOS PRE Windows
The rule states no platform. This is derived from the 4 ATT&CK techniques it maps to.
Log source category: sysmon_for_linux_eventid_1

Known benign triggers

Legitimate developers may use these GCC flags when building shared libraries that require initialization functions. Filter based on known development environments and trusted users.
