Cyberattacks in 2026 are spreading across national infrastructure, public data and global companies, prompting warnings that security threats are entering a new phase.

Cases cited include alleged mishandling of U.S. Social Security data, attacks on European power and water facilities, disruptions at large firms, open-source supply-chain compromises and an intrusion into part of the FBI’s monitoring systems.
