QQ chat records contain a lot of personal information. Once used for online fraud, the consequences will be disastrous. So we must not think that QQ chat history is not important and ignore it.
1. Why QQ chat records can be stolen
In fact, the reason why QQ chat records can be peeped is mainly due to a vulnerability that can bypass passwords and log in locally. When a user logs into QQ in the system, a folder for the QQ number will be generated in the QQ installation directory, which stores all the configuration information, chat records, etc. of the number.
Through this vulnerability, hackers can bypass the password verification of the remote system, thereby breaking through the limitations of the QQ program itself, and obtaining the information content recorded locally. In fact, since the advent of Tencent QQ, all QQ and TM software have this vulnerability. Therefore, whether in the local system or the remote system, you only need to obtain the files in this directory.
If it is local, the hacker only needs to unzip the relevant hacking program to the QQ installation directory, then run the program and select any QQ number that has been logged in, and then enter any password in the "QQ Password" below to successfully log in offline. After successful login, you can use it to view the target QQ account's friend information, chat history, etc.
If it is a remote computer system, then you need to use a program to move the files in the directory to the local system, and then use a hacker program to view the chat content.
2. Chat record anti-theft techniques
Tip 1: First, strengthen the security protection capabilities of the system to prevent the system from being invaded by malicious programs. Also, do not allow strangers to use your PC, as they may install malicious programs on the system, for example, after repairs are completed. Tip 2: To deal with this tool that peeks into friends' information and chat records, the best way to prevent it is to encrypt the chat records. Click the "System Settings" command in the QQ panel, then in the pop-up "QQ Settings" panel, select the "Local Information Security" option under "Security Settings", select the "Enable Chat History Encryption" option, and set the required password.
Tip 3: If it is a public computer, you can either select "Internet Cafe Mode" in the QQ login window, or set the "Automatically clear chat history when exiting QQ" option in the "Security Settings". In this way, you can let the program automatically clear your chat history when you exit.
