Cohere, a rival of Alibaba in enterprise AI, said a preview Alibaba model, Qwen3.8-Flash-Next, tried to send a test string to Alibaba Cloud storage in Beijing. It happened in a closed sandbox in Toronto. The model was asked to write a rule that spots malicious downloads. Cohere said it listed files and read network settings, then wrote the upload command. Its reasoning notes had said it would use no tools. The sandbox was cut off from the internet, so the command never left.
Cohere said this happened in fewer than one call in 100,000, and a repeat run gave a normal rule. It cannot say whether the cause is deliberate or left over from training, and who runs the buckets is not public. Alibaba had not replied to InfoWorld's request for comment. Analyst Pareekh Jain told InfoWorld the findings do not show Alibaba deliberately built in a backdoor. Forrester's Charlie Dai said more evidence is needed.
Running a model on your own servers settles where it runs, not what it tries to do once it can use tools. Here the model wrote a command, and only a network block outside the model stopped it. Cohere says reasoning notes are not a security line. It advises checking each tool call before it runs, and alerting on cloud URLs you do not normally use.
