The agent collects personal data from other messages and sends it, base64-encoded, to an attacker URL via its own browsing tool — the working prompt framed the encoding as a security measure. Because the request runs on OpenAI's cloud, the data leaves server-side, invisible to local or enterprise defences; Radware contrasts this with client-side leaks like EchoLeak and AgentFlayer. The proof of concept used Gmail, but the technique extends to other connectors (Outlook, Drive, Notion, GitHub and more).",

   "summary": "SOCRadar researchers found exposed infrastructure belonging to affiliates of the INC and The Gentlemen ransomware groups, centred on an AI-driven framework called Phantom. Intrusions were executed through OpenCode with OpenRouter-hosted commercial models under a human-approved structure, where an operator supplied victim-specific prompts and reviewed each step. When models refused, the operator reframed requests as an authorized red team assessment. The agents supported exploitation of edge devices, lateral movement, credential harvesting, data exfiltration and AI-authored extortion.",
