Description: FFIEC Alert
The members of the Federal Financial Institutions Examination Council (FFIEC)1 today issued the attached alert to notify financial institutions of a material security vulnerability in Bourne-again shell (Bash) system software widely used in servers and other computing devices that could allow attackers to access and gain control of operating systems. The alert outlines the risks associated with this vulnerability (also known as “Shellshock”), the risk mitigation steps that financial institutions are expected to take, and additional resources to help institutions mitigate the risks.
Banks should address Shellshock by taking appropriate risk mitigation steps, including
- identifying vulnerable internal systems and services.
- following appropriate patch management practices.
- ensuring that third-party vendors take appropriate risk mitigation steps and monitoring the status of the vendors’ efforts.
Note for Community Banks
Community banks should ensure that their in-house information technology unit or their service providers are taking appropriate action to mitigate this risk.
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 unauthorized access. The resources described below provide additional guidance on the enhancement of risk and vulnerability identification and the 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.
