VNX-GH-021 – Secrets sent to an external host

Overview

Token-theft campaigns add a step that dumps every secret (or the whole environment) and posts it to a server they control, often base64-encoded to slip past log masking, then remove the workflow. Authenticated calls that pass a single secret to an API are not reported; only bulk dumps, encoded secrets, and destinations with no legitimate use are.

Severity: Critical | Confidence: high | CWE: CWE-200, CWE-506 | Command: vulnetix gha workflows

Mappings: T1552.001, T1567

Remediation

Remove the step and treat every secret available to the workflow as compromised: rotate them, then review who added the change.
