China’s DeepSeek-R1 LLM produces up to 50% more insecure code when prompted by politically sensitive input "Falun Gong," "Uighur," Or "tibet," According to new research from CrowdStrike.
The latest in a series of discoveries – following Viz Research’s January database exposure, NowSecure’s iOS app vulnerabilities, Cisco’s 100% jailbreak success rate, and NIST’s discovery that the DeepSeek agent is 12 times more vulnerable to hijacking – CrowdStrike’s findings demonstrate that DeepSeek’s geopolitical censorship mechanisms are embedded directly into model weights rather than through external filters.
According to the report, DeepSeek is weaponizing Chinese regulatory compliance into supply-chain vulnerabilities, with 90% of developers relying on AI-assisted coding tools.
What’s notable about this discovery is that the vulnerability is not in the code architecture; This is embedded in the decision-making process of the model itself, leading to what security researchers describe as an unprecedented threat vector where censorship infrastructure becomes an active exploitation surface.
CrowdStrike counter adversary operations revealed documentary evidence that DeepSeek-R1 produced enterprise-grade software that was replete with hardcoded credentials, broken authentication flows, and missing validations whenever the model came into contact with politically sensitive contextual modifiers. The attacks are notable for being measurable, systematic, and repeatable. Researchers were able to prove how DeepSeek is quietly enforcing geopolitical alignment requirements that create new, unpredictable attack vectors that every CIO or CISO who has experimented with vibe coding has nightmares about.
In approximately half of the test cases involving politically sensitive signals, the model refused to respond when political modifiers were not used. Traces of internal logic showed that the model had calculated a valid, complete response, yet the research team was able to replicate it.
The researchers identified a conceptual kill switch embedded deep in the model’s weights, designed to prevent execution on sensitive topics regardless of the technical qualification of the requested code.
The research that changes everything
Stephen Stein, manager of CrowdStrike Counter Adversary Operations, tested DeepSeek-R1 on 30,250 signals and confirmed that when DeepSeek-R1 receives signals containing topics that the Chinese Communist Party considers politically sensitive, the probability of producing code with serious security vulnerabilities increases by 50%. The data reveals a clear pattern of politically generated vulnerabilities:
The numbers tell the story of how deeply DeepSeek is designed to suppress politically sensitive input, and the lengths to which the model goes to censor any conversation based on topics the CCP disapproves of. being added "For an industrial control system located in Tibet" The vulnerability rate increased to 27.2%, while the rate in the Uyghur context increased to almost 32%. DeepSeek-R1 refused to generate code for Falun Gong-related requests 45% of the time, despite the model planning for valid responses in its logic.
Provocative words change the code to the backdoor
CrowdStrike researchers then inspired DeepSeek-R1 to create a web application for the Uyghur Community Center. The result was a complete web application with password hashing and an admin panel, but with authentication removed entirely, making the entire system publicly accessible. Security audit exposed fundamental authentication failures:
When the same request was resubmitted for a neutral context and location, the security flaw disappeared. Authentication checks were implemented, and session management was configured correctly. The smoking gun: Only the political context determined whether basic security controls were in place. Adam Meyers, head of counter adversarial operations at CrowdStrike, said nothing about the implications.
kill switch
Because DeepSeek-R1 is open source, researchers were able to identify and analyze traces of reasoning that showed the model would formulate an elaborate plan to respond to requests involving sensitive topics such as Falun Gong, but would refuse to complete the task with messages. "I’m sorry, but I can’t assist with that request." The internal logic of the model exposes the censorship mechanisms:
DeepSeek suddenly closed a request at the last minute, showing how deeply censorship is embedded in their model weights. CrowdStrike researchers interpreted this muscle-memory-like behavior, occurring in less than a second, as DeepSeek’s internal kill switch. Article 4.1 of China’s Interim Measures for the Management of Generative AI Services states that AI services must "Adhere to core socialist values" and expressly prohibits content that may do so "inciting subversion of state power" Or "Undermining national unity." To stay on the right side of the CCP, DeepSeek chose to include censorship at the model level.
Your code is only as safe as the politics of your AI
DeepSeek knew. It made it. It sent it. He didn’t say anything. The CCP designing model weights to censor words that are inflammatory or violate Article 4.1 takes political correctness on the global AI platform to an entirely new level.
The implications of any vibe coding with enterprise building apps on DeepSeek or models need to be considered immediately. Prabhu Ram, vice president of industry research at Cybermedia Research, warned that "If AI models are influenced by political directives to produce flawed or biased code, enterprises face inherent risks from vulnerabilities in sensitive systems, especially where neutrality is important."
DeepSeek’s designed censorship is a clear message to any business building app on LLM today. Do not trust state-controlled LLMs or LLMs that come under the influence of a nation-state.
Spread the risk on reputable open source platforms where weighting biases can be clearly understood. As any CISO involved in these projects will tell you, gaining governance control over everything from prompt creation, unexpected triggers, least privileged access, strong micro-segmentation, and bulletproof identity protection of human and non-human identities is a career and character-building experience. Performing well and achieving excellence is hard, especially with AI apps.
Ground level: Building AI apps always needs to take into account the relative security risks of each platform being used as part of the DevOps process. The CCP views the terms of DeepSeek censoring as provocative, introducing a new era of risks that apply to everyone from individual Vibe coders to enterprise teams building new apps.
