Vect Ransomware Wipes Data from LiteLLM Supply Chain Victims

Organisations affected by the LiteLLM and Trivy supply chain compromises paid Vect to recover their data. The recovery tool was a wiper; it destroyed any file larger than 128KB and left nothing recoverable, even for the attacker. The service was called ransomware, but its actual product was closure.

Cohere AI Sandbox Flaw Allows Root Code Execution

Terrarium was designed to sandbox arbitrary code execution inside Cohere's AI environment. CVE-2026-5752, rated CVSS 9.3, allowed full root code execution and container escape via JavaScript prototype chain traversal. It remains unclear how many sandboxes must be escaped before the industry reconsiders building them.

Air Canada Loses in Court After Chatbot Invents Its Own Policy

Air Canada deployed a chatbot to handle customer service inquiries, including questions about bereavement fares. It invented a retroactive discount policy that did not exist; a tribunal ordered payment of CAD $812.02 and ruled that companies cannot disclaim liability for chatbot outputs. Air Canada argued it was not responsible for its own chatbot's statements, which is the kind of legal theory that works until it doesn't.
