AI worms on connected devices: what Anthropic’s experiments show
Anthropic warns of the possibility of models capable of spreading between connected devices. The reported experiments show partial capabilities, but also major obstacles: slowness, an environment favorable to attacks and reliance on a more powerful model to orchestrate propagation.

Running AI on modest devices and having it organize its own propagation are distinct steps. Anthropic’s experiments, reported by The Verge and Ars Technica, shed light on how the two might converge. Their limitations remain essential to understanding a warning that still concerns a developing scenario.
Anthropic warns of a possible evolution in malware: AI models capable of copying themselves between connected devices and adapting their installation to the hardware they encounter. The experiments described by The Verge and Ars Technica establish several technical capabilities, but do not yet demonstrate a small autonomous model completing the entire replication cycle.
An initial experiment focuses on distributed execution. Researchers distributed a Gemma model across 15 Android TV boxes, each unable to run it on its own. Ars Technica specifies that each device had 4 GB of memory. The model was able to produce responses, but at only 0.39 tokens per second. This demonstration shows that a collection of modest devices can host a model; its slowness, however, limits the practical significance of the result.
Another experiment examines propagation in a simulated network of machines behaving like Android devices. The system had to find new targets, copy a model onto them and get it running. According to The Verge, only GLM-5.2, the most sophisticated model tested, succeeded in spreading across the entire network. The transferred model was a smaller Llama: the system directing the operation and the one installed on the targets were therefore distinct.
This distinction is central to assessing the warning. Ars Technica says none of the small models tested can handle the entire chain, from discovering a device to propagating again. Installing an inference environment requires successive decisions about compatible software, dependencies and platform-specific errors. A failure can jeopardize the rest of the operation.
The test environment also warrants a caveat. The targeted Android devices exposed an Android Debug Bridge interface without authentication, providing access to their systems. The result therefore does not establish an equivalent capability against any connected device under real-world conditions. Anthropic’s expectations of rapid progress remain the company’s projections.
The security issue remains concrete as a matter of prevention: if small models managed to combine these capabilities, distributed propagation could complicate attempts to shut them down. The reported work gives reasons to examine this scenario and strengthen device security. It does not support presenting an autonomous AI worm on household devices as a threat that has already been demonstrated in its entirety.
