What it detects

This rule detects execution of the TruffleHog secret-scanning tool on developer or build hosts, where adversaries run it to harvest credentials and API keys from repositories and filesystems. It is associated with software supply chain attacks that repurpose legitimate developer utilities for credential theft. Detecting unexpected TruffleHog runs flags opportunistic secret collection.
