New ClosedQuorum Windows malware uses AI for attack decisions

ClosedQuorum is a Windows malware that uses multiple AI models (Google Gemini, DeepSeek, Qwen, and Mistral) to autonomously decide what actions to take during an attack without needing a human operator to give commands. The malware can steal credentials and data, inject malicious code, maintain persistence on a system, or move laterally to other computers, then send stolen information to attackers through Discord. Cisco Talos researchers warn this represents a shift toward fully automated attack chains that can run at any time.
