Source: The Hacker NewsAlso reported by The Register

Google Threat Intelligence Group and Mandiant warned on Monday that attackers are hijacking enterprise access to large language models, a tactic they call LLMjacking. They reported fraudulent cloud charges above $100,000 in a single day at some organisations, with cumulative charges reaching $1 million before access was revoked. The report also describes LLM Mixers, illicit gateways that resell unauthorised LLM access, including Jet Night, which offers an unlimited token plan for about $60 a month.

Why it matters

Organisations whose LLM API keys or cloud credentials are stolen can be billed for attacker usage, with some incidents exceeding $100,000 in one day.
