Description

Detects execution of SUID binaries that may be used for privilege escalation under the root effective user when the real user and parent user are not root, combined with minimal argument counts and suspicious parent context (interpreters, short shell -c invocations, or parents running from user-writable paths) to indicate potential misuse of SUID binaries for privilege escalation.

Detection logic

Its licence does not clear it for publishing here

Sunturai publishes a detection's own text where the licence it arrived under has been reviewed and permits it, and Elastic License 2.0 has not. The query as its source wrote it, its canonical form and the hash that pins this revision are in the workspace record.

Known benign triggers

  • Some automation or break-glass tooling may invoke SUID binaries from scripts under /home; validate parent identity and change tickets before escalating.
