JPMorgan Chase and BNY Mellon have halted electronic data sharing with the Office of the Comptroller of the Currency (OCC) after a significant breach compromised sensitive financial and investigative information in the regulator’s email system.

The breach involved unauthorized access to emails containing highly sensitive information about the financial condition of federally regulated institutions. The OCC has notified Congress and, after consulting with the Department of the Treasury, classified this event as a "major incident."

Banks provide the OCC with confidential information, which not only includes standard financial data but also highly sensitive details related to terrorism, espionage, and other investigations. Due to the severity of the security breach, financial giants like JPMorgan Chase and BNY Mellon abruptly severed electronic data exchanges with the OCC.

The OCC is currently collaborating with cybersecurity experts to analyze the breach, evaluate its IT systems, and maintain oversight of the situation. Despite the disruption, the OCC's onsite examiners continue to have access to bank information as necessary to carry out supervisory duties while ensuring data security.

This incident highlights the vulnerabilities in even the most critical financial regulatory environments and underscores the evolving challenges banks and regulators face in protecting sensitive data amid increasing cyber threats.
