What it detects

This rule detects trufflehog being executed to scan the local filesystem for verified secrets and emit JSON output, the credential-harvesting behavior of the Shai-Hulud npm supply-chain worm. The worm runs trufflehog on compromised developer machines to collect cloud and registry tokens for further spread.
