Investigators in Poland probed a late-week cyberattack on the National Centre for Nuclear Research that was blocked before causing damage and initially linked to Iran; the report situates this incident within a wider surge of hacktivist and state-linked cyber operations (notably Handala, claimed IRGC ties) conducting large-scale data-wiping, exfiltration, DDoS, and ransomware attacks across Israeli, Gulf, and allied targets, including a major wiper event impacting Stryker and multiple ransom/DDoS incidents claimed by groups such as 313 Team and NoName057.
