"SonicWall reported 264,000 security events targeting UK healthcare in January–May 2026, a tenfold increase from 27,000 in all of 2025. 41% of attacks exploited Log4Shell, while newer vulnerabilities like React2Shell and F5 BIG-IP bypasses were also used. Patching is hindered by embedded Java clinical applications. The surge coincides with a global ICS/OT attack wave and may involve Iranian threat actors."
