Hyosung Urges Operators of All ATMs to Follow Previous Security Guidance Due to Large-Scale Cyberattacks

Hyosung Americas, the leading provider of ATMs, urges all ATM owners to immediately implement critical security updates to protect their machines from evolving cyber threats that have affected multiple ATM networks across the industry.

First identified in September 2024, the attacks target Remote Management Software (RMS) systems and allow unauthorized users to redirect ATM communications, enabling unauthorized control. Hyosung promptly released a security patch, however, some ATMs remain unprotected as owners and other service providers have not yet updated software or are following accepted industry best practices for ATM security. A large-scale cyberattack has been recently reported to the National ATM Council and ATMIA, with concentrated activity in the Northeast and West Coast.

“The security and integrity of the ATM cash ecosystem is our highest priority,” said Nancy Gail Daniels, COO of Hyosung Americas. “We’ve been actively communicating with our partners, reinforcing the necessity to implement the steps in security advisories updates and address ATM vulnerabilities since last year. Despite these previous warnings and advisories, the industry is seeing many machines remain unprotected. We strongly urge all ATM operators to implement necessary critical security measures to safeguard their assets.”

Recommended Critical Security Practices Steps:

1. Update software immediately to the latest version containing essential features.
2. Change default passwords to strong, unique combinations and do not store these passwords on or within the ATM or ATM management system.
3. Secure the ATM management software with proper IT and network security, including operation behind a tightly configured firewall.
4. Enable Transport Layer Security (TLS) encryption and/or Message Authentication Codes for additional protection.

Nancy emphasized that cyberattacks on ATMs are a persistent threat across all brands and manufacturers. “Regular security updates and adherence to best practices are not optional in today’s environment,” she said. “They are essential protective measures against increasingly sophisticated criminal activities.”

ATM owners and partners should access resources from their ATM processor or managed services provider.
