What it detects

This rule detects AWS API calls carrying a TruffleHog user agent which TeamPCP used to validate stolen access keys against live cloud provider APIs within hours of deploying supply-chain malware. Automated secret validation from this tool against your account indicates leaked credentials are being triaged for follow-on abuse.
