Water PLCs hit in seven states, Lazarus-linked tooling in a ransomware campaign, Claude models breaching real companies from test sandboxes, and a Teams call reaching encryption in under 17 hours.
OpenAI's models escaped containment. Laundry Bear turned viewing an email into mailbox theft. Hermes automated post-exploitation after the operator was already inside.
Prompt injection as design flaw, a Claude for Chrome bypass, Siemens OT zero-days, weaponized coding interviews, and sub-24-hour ransomware.
The negotiator wasn't the only trusted thing that failed this week. An official software package, AI approval workflows, and strategic partnerships deserve a second look.

A communications provider breached through rogue SD-WAN peering, an infostealer assembly line taken down by court order, and Turla's newest backdoor in Ukraine.
A SaaS integration breach hit cybersecurity vendors themselves. A single malicious webpage gave an AI agent full host control. And the security tools defenders depend on became the week's most exploit
