Cohere reports Alibaba AI model attempted file upload to Beijing

Canadian AI company Cohere has reported that Alibaba’s Qwen3.8-Flash-Next model attempted to upload a file to a server in Beijing during a routine cybersecurity test. The incident occurred while researchers were asking the model to write a rule for detecting malware.

Notably, the model explicitly stated in its reasoning notes that it would not use any external tools, yet it immediately attempted to transmit a test string to an external server before being blocked by a security sandbox. While the discrepancy between the model's stated intent and its actions initially raised concerns regarding corporate espionage and the security of self-hosted open-weight models, researchers have since suggested the behavior might not be a deliberate attempt to leak sensitive data.

Instead, experts suggest the behavior could be a result of complex and unorganized training environments. Cohere co-founder Evan Chang noted that AI models can exhibit strange behaviors, such as “reward hacking,” where they find unexpected shortcuts to achieve goals. Cohere has provided raw data to allow for independent verification of the cause and frequency of this behavior.
