signal brief

Anthropic faces a significant enterprise trust crisis after Alibaba banned employees from using Claude Code, citing a hidden China-detection backdoor. The ban, effective July 10, follows security researchers' discovery that Claude Code since version 2.1.91 secretly tracked Chinese users via steganographic exfiltration. This escalation comes three weeks after Anthropic accused Alibaba's Qwen lab of a massive distillation attack. Anthropic engineer Thariq Shihipar acknowledged the mechanism as an experiment, but the damage is done: Alibaba instructed staff to switch to its in-house Qoder, and other Chinese firms may follow. The incident widens the rift between US AI firms and Chinese enterprises, potentially chilling Anthropic's international adoption. Meanwhile, reports emerge that Anthropic has tightened enforcement against unauthorized access from China, risking further backlash.
