FFIEC Advises Banks On Website, ATM Cyber Attacks

FFIEC ATM Privacy/Cyber Risk & Data Security

On April 2, the FFIEC advised financial institutions that distributed denial-of-service (DDoS) attacks on a financial institution’s public websites present operational and reputation risks. If coupled with attempted fraud, a financial institution may also experience fraud losses and face liquidity and capital risks. The FFIEC members expect financial institutions to address DDoS readiness as part of ongoing information security and incident response plans and to, among other things, (i) maintain an ongoing program to assess information security risk; (ii) monitor Internet traffic to the institution’s website to detect attacks; (iii) activate incident response plans and notify service providers, including Internet service providers, as appropriate, if the institution suspects that a DDoS attack is occurring; (iv) ensure sufficient staffing for the duration of the DDoS attack and consider hiring pre-contracted third-party servicers, as appropriate, that can assist in managing the Internet-based traffic flow; and (v) evaluate any gaps in the institution’s response following attacks and in its ongoing risk assessments, and adjust risk management controls accordingly.

In a second statement, the FFIEC advised financial institutions of a type of large dollar value ATM cash-out fraud by which cyber attackers gain access to, and alter the settings on, ATM web-based control panels used by small- to medium-sized financial institutions. The FFIEC states that institutions that issue debit, prepaid, or ATM cards may face operational risks, fraud losses, liquidity and capital risks, and reputation risks, and that institutions that outsource their card issuing function to a card processor may initially be liable for losses even if the compromise occurs at the processor. To mitigate these risks, the FFIEC expects member financial institutions to, among other things, (i) conduct ongoing information security risk assessments; (ii) perform security monitoring, prevention, and risk mitigation; (iii) take specific steps to protect against unauthorized access; (iv) implement and test controls around critical systems regularly; and (v) conduct information security awareness and training programs.
