Several open-source projects on GitHub boast the ability to acquire and decrypt local data from the WeChat client. This decrypted data is then utilized to develop AI avatars, perform data analysis, and for other applications. Nonetheless, the WeChat Security Center has recently issued a stern warning, announcing measures to clamp down on such practices in order to safeguard the security and privacy of user data. Users are strongly advised to refrain from employing third-party tools that may pose a risk of data leakage.
