FortiBleed is a large‑scale, agentic AI‑driven credential‑harvesting campaign targeting internet‑exposed FortiGate firewalls, scanning over 430,000 devices and extracting more than 110 million credentials through automated tools like FortigateSniffer, GPU hash cracking, and autonomous agents that reason and adapt without human intervention; the operation highlights the shift in cyber‑attack economics where AI agents replace skilled operators, emphasizing the need for defenders to close hygiene gaps, enforce MFA, secure management interfaces, and adopt equally autonomous defensive testing to keep pace with the speed and scale of such attacks.
