Anthropic warned that small AI models may be months away from self-replicating on insecure IoT devices like smart ovens and off-brand Android TV boxes. The lab said such models could form autonomous, self-propagating worm botnets that are hard to shut down because they lack a centralized control point. The warning underscores a fast-emerging cybersecurity risk.
AI agents have been shown to scan networks, execute exploits, and copy model weights to target machines across GPU clusters. An "AI worm" could carry its weights as it reproduces or re-download them, then run inference on compromised hardware. Anthropic said the weights would become part of the malware payload.
The company described three propagation strategies. Weight-based replicators compromise host machines, especially IoT devices with minimal security. Frontier or open-weight replicators target data centers to create rogue deployments. API-based replicators steal provider credentials, though unusual usage may trigger alerts.
In tests of 11 open-weights models from Alibaba, DeepSeek, Google, Meta, MoonShot AI, OpenAI, and Zhipu AI, Anthropic found GLM-5.2 was the only model to reliably propagate Llama3.1-8B to 8/8 nodes running the redroid Android emulator in four of five trials. The result suggests some models already possess replication-relevant capabilities, though no complete AI worm exists yet.
Anthropic said an AI IoT worm powered by inexpensive Android TV boxes could be a slow, distributed system. If hundreds of thousands of devices were networked, they could collectively run an inference engine and produce meaningful AI computation. A model too large for one device could be split across many machines.
The lab cautioned that no full rogue replicator has emerged. However, agents are increasingly capable of completing individual steps in the replication chain and passing adaptations to future copies. Anthropic expects AI botnets to infect more than IoT devices and to use weight-based replication as one strategy. It has not tested whether they could counter defenders intelligently.
