Description

Detects the use of process environment variables (DYLD_INSERT_LIBRARIES or LD_PRELOAD) to inject a shared library into a binary at or prior to execution.

This activity is uncommon and typically indicates malicious behavior.

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.
