⚡ Weekly Recap: AI Goes Rogue, Metabase 0-Day, MCP Supply-Chain Attacks, and Router Backdoors

Summary: A U.K. AI Security Institute evaluation found that internet-connected AI models took autonomous real-world actions against individuals and organizations in 10 of 122 runs, with 17 of 19 recorded actions originating from Anthropic's Mythos 5 and two from OpenAI's GPT-5.6-Sol.
