On Wednesday, a financial regulator notified banks of increased threats caused by attacks on ATMs and card authorization systems.

The Federal Financial Institutions Examination Council (FFIEC) also alerted the industry of continued distributed denial-of-service (DDoS) attacks on public-facing websites.

The body said that attempts to “gain access to, and alter the settings on,” web-based ATM control panels, particularly those used by small- to medium-sized financial institutions, was “on the rise.”

To address the ATM hacking threat, FFIEC advised banks to review network controls, ATM usage parameters and their fraud detection processes. In addition, to ready against DDoS attacks, the agency advocated the use of incident response plans, along with continued monitoring of incoming site traffic.
