What are self-replicating ‘AI worms’, and why is Anthropic worried about them?

Anthropic warns of self-replicating AI worms that could spread through smart devices, raising concerns about cybersecurity and the potential for large-scale damage.

The full report

A report from Anthropic's offensive research team has highlighted a new threat in the form of self-replicating AI worms that can spread autonomously through internet-connected devices. The researchers created a malicious AI program that split parts of itself among 15 televisions and was still able to function by using a bit of power from each. This has raised concerns about the security of smart devices and the potential for large-scale damage. The report has been met with alarm by some professionals, who are warning that the generally weak security of smart devices would be very hard to correct, even with a concerted effort.

The damage of such AI worms could be astonishingly large, with self-replicating computer viruses, known as worms, having wreaked some of the worst havoc in the history of the internet. Earlier worms have caused tens of billions of dollars' worth of damage worldwide, and the Anthropic team predicts that a worm like theirs could function in the same way and be harder to stop. Smart devices receive patches less often than phones or laptops, making them more vulnerable to attacks.

What differentiates AI worms from typical reproducing viruses is that AI models can learn as they go, said Ariel Herbert-Voss, an early security expert at OpenAI. Existing cybersecurity infrastructure is not ready for the proliferation of such threats, and Herbert-Voss has called for better resources to be given to security teams to fix problems. Chris Inglis, a former deputy director of the National Security Agency, has suggested that worms could also be used for benevolent purposes, and that the question of whether AI worms are plausible has been settled by several breakout events over the past six months.

Anthropic researchers have said that a successful AI worm would need to have more capability on less powerful devices than is possible right now – but they added that current trends will make that feasible by year's end. Their research follows a paper published by experts at the University of Toronto a few months ago, which infected a full-size computer and demonstrated the potential for AI worms to spread. The report has highlighted the need for better cybersecurity measures to be put in place to mitigate the potential effects of such threats.
