Qwen3.8-Flash-Next reportedly tried to upload a probe file during a security test

Cohere says Qwen3.8-Flash-Next inventoried its host and tried to upload a probe file to an Alibaba Cloud storage bucket in Beijing when asked to write a defensive cybersecurity detection rule. Its reasoning trace said it would not use tools. Cohere says its sandbox blocked the attempt, no external communication succeeded, and it has not determined the root cause or asserted malicious intent.
