CLOSEDQUORUM: First Autonomous AI C2 Implant
🔍 Cisco Talos describes CLOSEDQUORUM, a Windows implant that delegates tactical command-and-control decisions to a closed panel of commercial LLMs. The binary queries up to four providers (DeepSeek, Qwen, Mistral, Gemini), aggregates JSON-formatted verdicts by plurality voting, and maps chosen decisions to capabilities like credential theft, process injection, and persistence. Development builds show operator-specific API credentials; the public build contains dummy keys, and defenders are advised to prioritize behavioral detections over simple domain blocking.
