Since the FFIEC alert, additional information regarding the OpenSSL vulnerability has emerged, indicating that it may affect a range of technologies including, but not limited to, internally and externally facing servers, network devices, printers, applications, and mobile devices. Given the evolving information about the scope and nature of this vulnerability, banks should remain vigilant and continue their ongoing risk assessments and monitoring to detect and prevent against unauthorized access to customer information. The resources listed below are available to financial institutions and provide additional guidance on risk and vulnerability identification, and implementation of appropriate risk mitigation and management practices.
Questions regarding the FFIEC statement should be directed to the Office of the Comptroller of the Currency’s Bank Information Technology Division at (202) 649-6340.
