CISA Pressed on Nightwing GitHub Leak by Senator Hassan

U.S. Senator Maggie Hassan has formally pressed CISA for answers regarding an alleged data leak involving government contractor Nightwing. The incident, initially reported by cybersecurity journalist Brian Krebs, centers on a GitHub repository said to contain sensitive government data.

According to The Record by Recorded Future, the alleged breach raises significant questions about CISA’s oversight of its contractors and the security posture of critical government supply chains. The exposure of such repositories can provide attackers with invaluable intelligence, from system configurations to proprietary code, directly enabling more sophisticated attacks against federal agencies.

This isn’t just about one contractor; it’s a systemic concern. If a contractor’s GitHub instance can leak sensitive government data, it implies broader issues with security hygiene, access controls, and code management practices across the federal ecosystem. Defenders need to recognize that their attack surface extends far beyond their direct infrastructure to every third-party vendor and their development environments.
