  • •ATT&CK v20 introduces campaigns for attacks on Minnesota water utilities and Mexican government infrastructure.
  • •New software entries include CyberAv3ngers’ IOControl malware targeting IoT and OT devices.
  • •Enhanced detection strategies for ICS provide asset-specific context to improve threat response.

MITRE has released ATT&CK v20, expanding its framework to include new campaigns targeting critical infrastructure, specifically detailing attacks on over 30 Minnesota water and wastewater utilities and an AI-assisted breach of Mexican government infrastructure. The update introduces new software entries, including CyberAv3ngers’ IOControl malware, which targets Linux-based IoT and OT devices. The framework now includes enhanced detection strategies for industrial control systems (ICS), providing context for specific assets like PLCs. The new campaigns document adversarial activities that have not been formally attributed. The update also adds AI-focused techniques and analytics designed to filter out routine engineering activities. This release aims to bolster defenses against evolving cyber threats, particularly those leveraging AI. The current status of these threats remains under observation as security teams assess their impact.
