Senate seeks classified briefing over CISA credential exposure

Sen. Maggie Hassan has asked for an urgent classified briefing from acting CISA director Nick Andersen after reports that an exposed private contractor GitHub repository contained internal CISA and DHS credentials, logs and keys. Hassan seeks details on how the exposure happened, what was exposed, which contractor was responsible, and what steps are being taken to mitigate, with the briefing requested before June 5. CISA says there’s no indication sensitive data was compromised and is implementing additional safeguards.
