According to The Register, University of Toronto researchers used an unnamed, publicly available open-weight model released in 2025 to develop a self-propagating computer worm that spread through an enterprise test network. The worm reportedly adapts on the fly to identify known vulnerabilities and misconfigurations, then generates and executes attacks to move laterally and compromise additional machines, and the researchers say the system runs on a single GPU. Professor Nicolas Papernot is quoted noting that “it is not just the biggest and most powerful AI models that pose security concerns.” The paper omitted some methodological specifics and the model name, per The Register. Editorial analysis: Industry observers note this demonstrates free, small models lower the cost and operational complexity for adversaries to automate known-vulnerability exploitation at scale.
