What happened
Multiple high-impact security stories: several US healthcare data breaches (hundreds of thousands-to-millions of records) were added to the HHS tracker. A critical NGINX vulnerability was patched but is being exploited in the wild and PoC code published, enabling DoS by default and potential RCE in some configurations. ‘Claw Chain’ (four chained OpenClaw vulnerabilities) can steal credentials, escape sandboxes, and install persistent backdoors. Grafana confirmed a breach attributed to a group tied to ShinyHunters/Coalition actors, and 7‑Eleven confirmed a ShinyHunters data theft of >600k CRM/S
