Researchers Build Self-Replicating AI Worm That Operates Entirely on Local, Open-Weight Models

University of Toronto researchers have developed a proof-of-concept AI worm that autonomously navigates networks, generates customized attack strategies, and self-replicates using only locally hosted open-weight language models. The system operates independently without human intervention or reliance on commercial AI services, demonstrating significant cybersecurity implications for enterprise env

University of Toronto researchers have built and tested a proof-of-concept AI-driven computer worm that uses a locally hosted open-weight large language model to reason its way through a network, generate tailored attack strategies for each target it encounters, and replicate itself, all without human intervention and without touching a commercial AI service. The preprint, posted to arXiv on
