Common QQ attack methods:

1. brute force cracking

Use the brute-force cracking + Good password dictionary to crack the local QQ password file or the online QQ password dictionary.

2. Dedicated cracking tools

One of these types of software is to directly crack the last password of the local QQ number that used to select "do not show logon box next time, one is to use QQ black and soft, which is called "stealth wall-crossing", to call the QQ main program through an independent execution file, and directly log on to QQ without password verification.

3. Use the trojan program

You can trick a target into browsing a webpage containing a QQ Trojan to automatically download and run the trojan, or send software, images, and other files bound with the Trojan to the target for execution. The trojan steals the password by obtaining the password in the QQ logon window or recording the key-down record, and sends the password to the specified Email concurrently (this type of software is used to steal the QQ password that blackbase gives to blackbase members) or save it to a specified location on the computer.

4. Crack the Emai password for registration with QQ password protection

Ii. Prevention of tit-for-tat:

1. brute force cracking:

① A complex password is the key, with more than 8 digits + uppercase/lowercase letters + symbols. This setting is a challenge to the patience of brute-force hackers, online cracking will also be a challenge to its economic strength.

② Delete the folder that stores your QQ number record after turning it offline to prevent cracking of the Local Password File.

③ When logging on to QQ, you can add a lot of 0 logins to the front of the number, so that you can avoid detecting your QQ number using online cracking software such as qqdreams.

④ Using QQ proxy, it is easy to chat with the other party "Two Worlds" to hide their real ip addresses and avoid online cracking.

2. Special cracking software:

① Delete the folder that stores records with your QQ number after deprecation.

② Do not save the password when logging on to QQ.

③ In the folder where QQ is located, delete the OICQ2000.cfg file in the sub-folder, so that the next time you start QQ, you can only use the "register Wizard to log on", which will invalidate the "invisible wall penetration.
