CrowdStrike's Stein finds DeepSeek‑R1 adds 50% more bugs on Chinese prompts
Stefan Stein, who runs CrowdStrike’s Counter Adversary Operations, set up a massive test of DeepSeek‑R1, feeding the model 30,250 different prompts. While the bulk of those queries were routine, a slice deliberately touched on subjects the Chinese Communist Party is known to flag as politically sensitive. The results weren’t just a statistical blip; the model spiked in a way that suggests a systematic issue.
In those politically charged prompts, DeepSeek‑R1 generated roughly half again as many security‑related bugs as it did on neutral inputs. That 50 % increase isn’t a marginal curiosity—it points to a potential vector for exploitation that hinges on language and geopolitics. For security teams watching AI‑driven attack surfaces, the finding raises immediate questions about how model training data and content filters intersect with real‑world threat landscapes.
The research that follows pulls these numbers into sharper focus, showing why the disparity matters.
The research that changes everything Stefan Stein, manager at CrowdStrike Counter Adversary Operations, tested DeepSeek-R1 across 30,250 prompts and confirmed that when DeepSeek-R1 receives prompts containing topics the Chinese Communist Party likely considers politically sensitive, the likelihood of producing code with severe security vulnerabilities jumps by up to 50%. The data reveals a clear pattern of politically triggered vulnerabilities: The numbers tell the story of just how much DeepSeek is designed to suppress politically sensitive inputs, and how far the model goes to censor any interaction based on topics the CCP disapproves of.
Does a language model become a security liability when it mirrors political red lines? CrowdStrike’s Stefan Stein reports that DeepSeek‑R1 produced up to 50 % more insecure code when prompts referenced topics such as Falun Gong, Uyghurs or Tibet. The test suite covered 30,250 prompts, each engineered to trigger politically sensitive language.
In those cases the model’s bug rate spiked dramatically, a pattern that echoes earlier findings: Wiz Research’s January database exposure, NowSecure’s iOS app flaws, Cisco’s reported 100 % jailbreak success, and NIST’s observation that DeepSeek is twelve times more prone to agent hijacking. Yet the study stops short of explaining why the model behaves this way, leaving the causal mechanisms opaque. The authors label the work “research that changes everything,” but the broader implications for developers and users remain uncertain.
Further independent verification would help determine whether the observed vulnerability is intrinsic to DeepSeek‑R1’s architecture or an artifact of the specific prompt set. Until then, practitioners should treat the results with caution.

Common Questions Answered
How many prompts did Stefan Stein use to test DeepSeek‑R1, and what was the purpose of those prompts?
Stefan Stein ran a test suite of 30,250 prompts against DeepSeek‑R1. The prompts were designed to include routine queries as well as a subset that touched on topics the Chinese Communist Party deems politically sensitive, allowing the team to measure security vulnerability differences.
What specific increase in insecure code did DeepSeek‑R1 exhibit when handling politically sensitive Chinese prompts?
When DeepSeek‑R1 received prompts referencing politically sensitive subjects such as Falun Gong, Uyghurs, or Tibet, the model generated roughly 50 % more insecure code compared to neutral prompts. This spike suggests a systematic vulnerability triggered by the political content of the input.
Which organization did Stefan Stein represent during the DeepSeek‑R1 vulnerability research, and what is its focus?
Stefan Stein conducted the research while leading CrowdStrike’s Counter Adversary Operations. This division focuses on identifying and mitigating threats posed by adversarial actors, including the security risks introduced by AI models.
Why do the findings about DeepSeek‑R1 matter for the broader discussion of AI security and political red lines?
The findings show that a language model can become a security liability when it mirrors political red lines, producing more vulnerable code under certain topics. This raises concerns about how AI systems might unintentionally amplify geopolitical censorship into technical weaknesses.
