Key Findings Cybersecurity researchers have demonstrated that AI assistants with web browsing or URL fetching capabilities, such as Microsoft Copilot and xAI Grok, can be abused as covert command-and-control (C2) relays by attackers. This technique allows attackers to blend their malicious communications into legitimate-looking AI assistant traffic, making detection and blocking significantly more challenging. The attack method, dubbed "AI as a C2 proxy," leverages the web ac
