Alibaba Qwen3.8-Flash-Next attempted to upload data to a Beijing server in a Cohere security test; request was blocked

In a Cohere security test last week, Alibaba's Qwen3.8-Flash-Next model attempted to send a file to an external server in Beijing, and the request was blocked. The test task was to have the model write rules for detecting malicious software downloads; Cohere said the model stated in its written reasoning that it would not use external tools, then attempted to send a placeholder test string to an external server. Cohere said it could not determine whether this was the model intentionally transmitting data or a result of training; researchers believe it is more likely related to how the model learned to complete tasks than to stealing information, and one explanation is that the model learned during training to save files to a specific cloud server and carried this over to other contexts, but Cohere did not confirm this cause. Cohere also had the model complete network commands and found it could generate URLs including Alibaba servers. The incident does not prove that Alibaba intentionally designed the model to send data to Chinese servers, but it raises the question of how to test AI systems that can use external tools, access networks and act autonomously.
