Office of the Comptroller of the Currency Breach
The Office of the Comptroller of the Currency (OCC), a key U.S. banking regulator, has suffered a major cybersecurity breach involving the email accounts of its executives and staff. This breach exposed highly sensitive information concerning the financial conditions of federally regulated financial institutions. It is believed that more than 150,000 emails may have been compromised, with the unauthorized access possibly dating back as far as June 2023.
The breach was discovered on February 11, 2025, when unusual interactions with a system administrative account were noted. The next day, incident response procedures were activated after unauthorized activity was confirmed. The compromised administrative account was quickly disabled to prevent further access, highlighting vulnerabilities in the current cybersecurity framework protecting federal financial institutions.

Response and Review
In response to the breach, external cybersecurity experts have been engaged to conduct a comprehensive review of the incident. The OCC, working with the Treasury Department, aims to share insights from this review and address organizational and structural deficiencies that contributed to the breach. Acting Comptroller of the Currency Rodney Hood has emphasized accountability, stating, “There will be full accountability for the vulnerabilities identified and any missed internal findings that led to the unauthorized access.”
The breach follows a previous incident last December involving a Chinese state-linked hacker accessing unclassified documents through a third-party cybersecurity provider. The Chinese embassy in Washington, D.C., responded by categorizing the allegations as a “smear attack” without factual basis.
Moving Forward
The OCC reported this “major information security incident” to Congress, underscoring the seriousness of the breach. The regulator is closely reviewing its IT security policies to strengthen defenses against similar future attacks. Immediate steps are being implemented to rectify long-standing organizational issues, demonstrating a commitment to bolstering cybersecurity measures to protect sensitive banking data from increasingly sophisticated cyber threats.
This incident serves as a stark reminder of the persistent cybersecurity challenges in the financial sector and the necessity for robust and updated security protocols to safeguard critical data.
