Anthropic warns "AI worms" could soon infect smart home devices

Key points

• Anthropic warns small AI models may be months away from self-replication.
• AI worms could spread across smart home devices with weak security.
• Researchers urge hardening systems and preparing for persistent AI replicators.

Anthropic warned on Monday that self-replicating AI worms could soon infect internet-connected smart home devices. In a report, the company's safety researchers said small AI models may be only months away from cloning themselves and spreading across devices such as smart ovens, TVs and vacuum cleaners.

Anthropic, which developed the Claude chatbot, said such agents would be hard to control because there is no centralized point to shut off. Stronger AI models already can perform end-to-end replication, a threshold smaller models could reach by year-end, the researchers said.

How the worms could spread

AI worms are AI-powered malware that can spread quickly across networks and devices while avoiding detection, according to cybersecurity firm Palo Alto Networks. Anthropic researchers said smart home devices and internet-connected equipment like security cameras are vulnerable because they tend to have weaker security protections.

In a worst-case scenario, a swarm of AI agents working toward a shared goal could spread across computer hardware using replication schemes. The researchers said they do not know what form such attacks could take, suggesting the models could be distributed as digital slime mold or as more powerful models able to hack into data centers.

We should aim to harden our systems to make it difficult for such replicators to spread, but also prepare to deal with a world where they are here to stay
