Security researcher claims 6TB of intercepted data could compromise 19 major firms including Huawei and Xiaomi

Security researcher Shou Chaofan (寿超璠) stated he purchased 6TB of data from a major Chinese LLM proxy service, containing sensitive credentials such as SSH keys, VPN configurations, and API tokens. He claims this data provides access to the internal systems of 19 major Chinese companies, including Huawei, Xiaomi, NIO (蔚来), and MiniMax, as well as seven government-related entities. The researcher, a co-founder of blockchain security firm Fuzzland, warned that LLM proxies can intercept and store plaintext data, including sensitive keys embedded in agent contexts. He previously reported that several LLM proxies have been found injecting malicious code or misusing credentials.
