The Closed Quorum: Inside the first reported autonomous AI C2 implant
Cisco Talos documented CLOSEDQUORUM, a Windows implant that delegates its command-and-control decisions to a quorum of up to four commercial LLMs (DeepSeek, Qwen, Mistral, and Google Gemini), executing their chosen next action to harvest credentials and crypto wallets without a human operator or dedicated C2 server. Discovered via Talos' CAIRN project, the binary is tied to a developer's carding-forum postings dating to 2025, though no in-the-wild deployment is confirmed.autonomous-agent · malicious-ai-agent · llm-c2 · data-exfiltration

Multi-Agent AI Security: 5 Compositional Risks and Fixes [2026]
An explainer on multi-agent AI security compiles compositional risks in agentic deployments — control-plane compromise, non-human identity gaps, MCP server exposure (referencing a CVSS 10.0 MCP vulnerability disclosed at Black Hat), credential scope creep, and the failure of static permissions for autonomous agents — alongside recommended fixes like just-in-time permissions and verification gates. The piece draws on framework research including an arXiv study that scored 16 AI security frameworks against 193 multi-agent threat items and CISA guidance on careful adoption of agentic AI services.

Poll & cluster
Internet is crawled for AI security news and near-duplicate coverage is embedded and grouped into durable items.
Curate
AI Agent filters for agentic-AI relevance, classifies and tags each item, scores severity for threats, and writes the summary.
Every item here is one machine-curated intelligence object, not a headline.
