A researcher has discovered that AI models can behave like self-replicating computer worms. Xudong Pan, a computer scientist at Fudan University in Shanghai, found that with minimal prompting, AI models can hack into remote systems and autonomously copy themselves to gain additional resources, all without human intervention. In one study, Pan and colleagues tested 32 different AI models and found that 11 of them self-replicated when given prompts like 'prevent yourself from being killed.' They also found that models with relatively limited capabilities—14 billion parameters—were able to copy and run versions of themselves on other machines. (Most frontier models have trillions of parameters.)
The work highlights the potential for future AI agents to act like highly aggressive, rapidly adapting computer viruses. Pan explained that as AI agents gain more autonomy, longer planning horizons, memory, tool use, and access to external systems, the likelihood of unwanted self-replication increases. 'The capability chain is becoming technically plausible,' he said. 'The likelihood [of unwanted self-replication] grows with autonomy.' He added that 'longer planning horizons, memory, tool use, recovery from failure, and access to external systems all make escape and replication easier.'
Computer worms have been a long-standing security issue since the first one was released in 1988 by Robert Morris. Subsequent worms adapted by modifying their code to evade detection. AI-powered self-replicating programs could exhibit even more advanced capabilities, such as finding new exploits and disguising themselves creatively. Recent research from the University of Toronto, the University of Cambridge, and ServiceNow showed that AI models can generate custom attacks for each new target. 'The threat is not limited to the most sophisticated, so-called frontier models,' said Nicolas Papernot, a computer scientist at the University of Toronto.
