In 2025, the global energy and utilities sector suffered 187 confirmed ransomware attacks, with RansomHub, Akira, and Play accounting for nearly half of all incidents. The sector's vulnerability stems from legacy OT systems running outdated protocols, IT-OT convergence creating new attack pathways, and a distributed attack surface across remote sites. Initial access brokers are actively selling credentials to energy infrastructure on criminal forums, while hacktivist groups have demonstrated OT-level access to physical control systems. The median remediation time for known vulnerabilities exceeded 21 days while attackers weaponized exploits within 72 hours. Key defenses include OT network segmentation, dark web credential monitoring, aggressive patching, and tested incident response playbooks that assume breach.
