This Week in AI Security - 5th February 2026

In this first episode of February 2026, Jeremy breaks down a high-stakes week in AI security, featuring critical framework flaws, cloud-native exploits, and a major security warning regarding a popular autonomous AI agent.

Key Stories & Developments:

• Operation Bizarre Bazaar: Threat actors are actively targeting exposed LLM infrastructure to steal computing resources for cryptocurrency mining and resell API access on dark markets, attempting to pivot into internal systems via compromised MCP servers.
• Gemini MCP Tool Exploit: A critical Remote Code Execution (RCE) vulnerability was identified in a Gemini Model Context Protocol (MCP) tool, highlighting the recurring theme that the infrastructure powering LLMs remains a primary weak point.
• MoltBook API Leak: Researchers discovered a hardcoded Supabase API key in "MoltBook," a social network for AI agents. This flaw granted unauthenticated access to the entire production database, exposing over 1.5 million API keys.
• Bondu AI Toy Breach: A privacy failure in an AI-powered dinosaur toy left 50,000 chat log records exposed to anyone with a Gmail account, underscoring the lack of robust authentication in consumer AI IoT devices.
• CISA Chief's Data Mishandling: Reports surfaced that the acting head of the country's cyber defense agency uploaded sensitive "official use only" documents into a public version of ChatGPT, bypassing enterprise controls and security protocols.
