The Office of the Comptroller of the Currency (OCC) today notified Congress of a major information security incident, as required by the Federal Information Security Modernization Act.

This finding is the result of internal and independent third-party reviews of OCC emails and email attachments that were subject to unauthorized access. On February 11, 2025, the OCC learned of unusual interactions between a system administrative account in its office automation environment and OCC user mailboxes. On February 12, the OCC confirmed the activity was unauthorized and immediately activated its incident response protocols which include initiating an independent third-party incident assessment and reporting the incident to the Cybersecurity and Infrastructure Security Agency. On February 12, the OCC disabled the compromised administrative accounts and confirmed that the unauthorized access had been terminated. The OCC provided public notice of the incident on February 26.
