IronCurtain is an open‑source project that isolates AI assistants in a virtual machine and enforces user‑written policies written in plain English. By converting natural‑language rules into enforceable security constraints through a large language model, the system adds a layer of control that prevents rogue actions such as unwanted deletions or phishing. The prototype is model‑independent, logs policy decisions, and is positioned as a research tool for the community rather than a consumer product. Its creators emphasize the need for structured guardrails to keep agentic AI useful yet safe. Leer más

The discovery highlights a shift toward low‑profile, individual‑targeted extortion by cybercriminals. Leer más
