Ransomware at ChipSoft disrupted Dutch hospitals, while Signature Healthcare diverted ambulances after a cyberattack. UK authorities linked router hijacking to a Russian military unit, and Northern Ireland schools faced network outages. Treasury launched crypto threat sharing, the NCA froze $12 million in scam proceeds, and NIST advanced AI risk guidance for critical infrastructure operators amid rising supplier and mobile exposure.

In this 48-hour roundup we track insider-driven mega breaches, disrupted court and logistics systems, and fresh leaks from healthcare and consumer apps. New OT and backend vulnerabilities join the KEV list, while Europol’s Cryptomixer takedown and UK ransomware-reporting plans show growing pressure on the criminal business model and on unprepared boards, demanding faster, evidence-led response and genuinely risk-based cyber governance.

The latest 48 hours saw coordinated attacks on London councils, a breach at Harvard, and ransomware disrupting US emergency alerts. Industrial firm Balkrishna Paper Mills and major banking vendor SitusAMC also reported compromises. Active exploitation of a FortiWeb zero-day, a revived npm worm campaign, and a huge Android fiction-app data leak round out a high-impact period.
