Threat actors parsed the .bak file into lightweight databases and hosted public search engines (e.g., "Kaifang" search sites). Anyone could type in a name or ID number to see exactly when and where their acquaintances had stayed.
To understand the threat, we must first understand the anatomy of the file name:
Furthermore, if the file is found in a public repository (e.g., a public GitHub repository or a misconfigured OSS bucket), the data controller may face criminal liability under the Criminal Law for "infringing on citizens' personal information."
The file is a digital backup of a Chinese National Identity Card (Shenfenzheng), often found on servers or personal devices after a user has uploaded their ID for identity verification.
