Unlike traditional viruses, these AI-powered worms do not require human interaction to spread and can adapt their strategy as they move across computer networks, exploiting vulnerabilities. Researchers at the University of Toronto simulated these capabilities in a secure digital lab, demonstrating that such self-sustaining AI-driven cyber-threats are no longer theoretical. The worms can parasitically use compromised machines to run open-access large language models, gather information, tailor attacks, and extend their reach to further targets across various devices. Experts emphasise the urgency for researchers, industry leaders, and policymakers to take action, warning that every internet-connected device is a potential target and urging users to apply software updates promptly.

This prototype could help the world prepare for AI malware threats, according to the researchers who made it

A team of researchers have shown how a self-replicating AI agent can take over a computer network at almost no cost.

University of Toronto researchers built a worm powered by open-weight AI that adapts to its targets. Experts say it changes the math on cybersecurity defense

AI worms, or "viruses with wings and brains," adapt to new environments, seek out vulnerabilities, and will likely strike within a year, researchers say.
