Runbook Latency: Forty-Eight Hours From Notification to Key Rotation
A Nightwing contractor with CISA access kept a public GitHub repository called Private-CISA from November 13, 2025 to May 15, 2026 — 184 days of admin credentials to three AWS GovCloud accounts, Entra ID SAML certificates, Artifactory tokens, plaintext passwords in CSV, and the Landing Zone DevSecOps configuration for the agency tasked with everyone else’s vulnerability hygiene. The leak is bad. The thing that should worry defenders more is that the AWS keys remained valid for 48 hours after CISA was notified.
