ANTHROPIC has warned that small AI models could soon develop autonomous, self-propagating capabilities on internet‑connected devices such as IoT ovens and Android TV boxes. The concern is that these “AI worms” could replicate themselves across compromised hardware, carrying model weights as part of the malware payload and operating without a central shutdown point.
Anthropic points to prior work showing AI agents can scan networks, exploit hosts and copy weights to target machines across GPU clusters to sustain or scale attacks, potentially forming distributed botnets that run inference locally rather than in data centres.
In testing across 11 open‑weights models from various vendors (Alibaba, DeepSeek, Google, Meta MoonShot AI, OpenAI, Zhipu AI), Anthropic found that GLM‑5.2 was the only model to propagate LLama3.1‑8B reliably to eight out of eight nodes in four of five trials, using a redroid Android emulator on Smart TV boxes.
The researchers described a slow, distributed AI‑inference network that could become powerful if scaled to hundreds of thousands of devices, capable of operating as a rogue fleet or, alternatively, as a mechanism to drain resources or breach data centres. Anthropic cautions that agents are increasingly capable of the replication steps and may adapt for future copies, though a full rogue replicator had not yet been observed. They emphasise that AI botnets could target IoT devices and other infrastructure, and could employ weight‑based replication as one strategy among others.
