From a technical point of view, WeChat chat records are encrypted and stored, and only WeChat clients and official servers can decrypt and obtain chat records. Omis information technology may bypass the WeChat encryption mechanism to obtain chat records through some technical means, but this practice is illegal, which may infringe on users' privacy rights and may also involve crimes.
In addition, Omis information technology needs to obtain the user's WeChat account, password and other information in the process of restoring the WeChat chat record, which also has certain security risks. If the security measures of Omis information technology are not strict enough, these sensitive information may be stolen by malicious people such as hackers, resulting in the loss of users' WeChat accounts and personal information.
Therefore, in order to protect personal privacy and information security, users are advised not to use third-party recovery tools such as Omis information technology to obtain WeChat chat records, but to operate through the backup and recovery functions provided by WeChat officials. At the same time, we should also strengthen the awareness of protecting personal information and avoid revealing personal privacy when using applications such as WeChat.
