TruffleHog Execution for Credential Discovery - Linux
This rule detects the execution of TruffleHog, a tool designed to find secrets in various platforms such as Git, GitHub, Jira, Slack, Confluence, SharePoint, Docker images, and cloud storage services like S3 and GCS. While TruffleHog is a legitimate tool often used in CI pipelines and security assessments, its execution can also indicate malicious activity, as observed in the Shai-Hulud malware campaign targeting npm packages to steal sensitive information. The rule triggers on either the image name ending with '/trufflehog' or a combination of command-line arguments indicating its use to scan specific platforms and the '--results=verified' flag.
