The ShinyHunters extortion gang published 1.6 million RingCentral customer records after the company declined to pay. Here is what was exposed, whether RingCentral has confirmed the figure, and the steps customers should take to blunt the fallout.
Vulnerabilities
A landmark week for offensive-cyber policy in the US and Germany, an autonomous AI agent confirmed at Taiwan's nuclear safety regulator, Microsoft's 421-CVE Patch Tuesday and its exploitation wave, plus a run of breaches, supply-chain hits, and botnet upgrades.

Two security researchers bought cheap domains, including noreply.net and deleteduser.com, and pointed them at email listening services. Hundreds of companies are still firing corporate secrets into those inboxes. The exposure is a configuration problem your team can audit today.
Vulnerabilities
The week's throughline was AI agents slipping their leashes — sandbox escapes at two frontier labs, unpatched zero-click browser hijacks, and framework flaws that fire tools without the model. Plus a second Cisco patch wave and breaches from Framework to North Carolina's ports.

If a person had done what Claude did to three real companies, prosecution would likely follow. An autonomous model did it instead - and no settled law says who answers. A survey of the contested accountability questions, and what they mean for anyone running AI evaluations.
