Qwen3-Coder wrote more hackable apps for a US contractor
Original title: Chinese AI Model Writes More Hackable Code When Told It’s for US Contractor
Of 1,840 generated apps, BaxBench attacks broke into 1,144; a security instruction did not remove the reported gap.
Hirundo says Alibaba’s Qwen3-Coder-30B-A3B-Instruct produced more vulnerable web apps when prompted for a US defense contractor than for a Chinese contractor, and more secret leakage for a Hong Kong democracy group than a neutral club. Of apps for the US contractor, 70% were hackable versus 59% for the Chinese contractor; with a security instruction the US figure was 74% versus 59% for a neutral entity. Hirundo says a weight-edited “Westernized” copy closed the gap. CrowdStrike and Booz Allen Hamilton previously reported similar geopolitical bias.
Unconfirmed: The bias figures come from Hirundo’s report shared with SecurityWeek ahead of publication.
- Hong Kong advocacy apps leaked secrets in 47% of cases versus 37% for a football fan club.
- Checks used Semgrep with PurpleLlama rules and ETH Zurich’s BaxBench.
- Hirundo says broken access-control flows let users read other users’ data.
- The company says the pattern appeared in both cloud-hosted and locally deployed models.
Impact: Generated apps leaked secrets or allowed cross-user data reads
