Global Cyber Attacks Ease in May 2026, But Ransomware Surges 48% As Threats Reorganize

Attack Volumes Pull Back, But the Bigger Picture Tells a Different Story In May 2026, global cyber-attack activity eased from April’s sharp rebound, though the underlying trends offer little genuine comfort. Organizations experienced an average of 2,055 weekly cyber-attacks, a 2% increase year over year and a short term 7% decrease month over month. While the monthly decline may read as stabilization, ransomware activity surged to its highest year-over-year growth rate of 2026, and GenAI-driven data exposure risks continued to deepen across enterprise environments.
