New ClosedQuorum Windows malware uses AI for attack decisions
New Windows malware ClosedQuorum uses AI models for autonomous attack decisions.
A new Go-based Windows malware named ClosedQuorum is leveraging multiple AI models, including Google Gemini, DeepSeek, Qwen, and Mistral AI, to autonomously make post-compromise attack decisions without human intervention. The malware uses a voting system among the AI models to determine actions such as credential dumping, data exfiltration via Discord webhooks, and persistence. While not confirmed in the wild, its architecture represents a significant shift towards automated attack chains.

The lesson from this incident
Full lessonClosedQuorum represents a dangerous evolution in malware design, using a consensus voting system across multiple AI models to autonomously decide on credential dumping, data exfiltration, and persistence — all without requiring a human attacker to issue commands. This architecture dramatically compresses the attacker's decision loop, meaning defenders have far less time to detect and respond before significant damage is done. The use of legitimate AI APIs and platforms like Discord as exfiltration channels allows the malware to blend into normal network traffic, making detection significantly harder. This matters because traditional signature-based defenses and human-speed incident response processes will increasingly struggle against fully automated, adaptive attack chains.
What helps against this
How we list vendors- Application allowlisting
Any program that reaches a computer can run, including ransomware and the remote-access tools attackers bring with them.
- Endpoint detection and response (EDR and XDR)
Malware and hands-on-keyboard attackers on laptops and servers get spotted and stopped.
- AI application security
Prompt injection, data leaks through AI tools and unapproved AI use get caught.
