Symantec Finds AI Agent Hijacking Unprotected Language Models for Cyberattacks

Symantec researchers discovered an offensive AI agent that hijacks unprotected language models, runs up to 100,000 steps autonomously, and uses them to scan, exploit servers, steal data and install cryptominers, logging over 127,000 requests from tens of thousands of addresses.

Why it matters

Hijacking of unprotected models forces product managers to embed authentication checks and usage caps into AI service offerings.
