Confrontation between the password and the keyboard for keyboard Security (figure)

Comments: Keyboard security problems and hazards through various hacker technologies, hackers can remotely control the installation of keyboard recording programs in users' computers, these tools, known as keyboard recorders, can record all information input from the keyboard. As hacking technologies are increasingly open to the public, even beginners can easily use these tools, leading to keyboard security problems and dangers.

With various hacker technologies, hackers can remotely control the installation of keyboard recording programs on users' computers. These tools, known as keyboard recorders, can record all information that users enter from the keyboard. As hacking technologies are increasingly open to the public, even beginners can easily use these tools, resulting in greater harm to users. Once the user's computer is installed with a keyboard recorder, the user's personal privacy information will be obtained, such as the bank account and password entered during online shopping or online banking transactions. Although online banking adopts the digital certificate authentication mechanism and encrypts the transmitted data to improve the security level, it can only protect the data transmitted to the network, personal computers cannot be protected. With the keyboard recorder, hackers want to steal not only user information on the browser, but also the accounts and passwords of applications such as games and instant chat tools.

To prevent such key information from being leaked, it is necessary to intercept it at the source. The following uses two adversarial tests to demonstrate how to protect data input from the keyboard.

Test 1: Window keyboard recorder VS Security keyboard

In Windows XP SP2, use the window keyboard recorder to record the keyboard. After running the window keyboard recorder, open notepad, enter some content at will, press F12 to call out the window keyboard recorder to view the content, and find the content we entered on the keyboard (including some control keys such as Shift key) all are recorded (1 ). Imagine that if you have logged on to online games such as QQ or legend during this process, these accounts and passwords have already been put into the hands of hackers.

Next we use a secure keyboard to combat the window keyboard recorder. The secure Keyboard software uses the unique keyboard security technology to modify the Windows Kernel and driver kernel in a software manner to protect the keyboard security and prevent important information from being stolen. The security keyboard has certain software protection functions. After running the Security keyboard, click the startup security status (2) on the interface, the program will be protected, and a "PK" icon will be generated at the system tray, double-click it, on the displayed page, click start or stop to quickly switch the keyboard protection status (3 ). Now run the window keyboard recorder and perform the same test according to the above method. Finally, it is found that the text content recorded by the window keyboard recorder is only the items that open the window, and the content entered by the keyboard cannot be recorded, the keyboard input is encrypted successfully.

Tip: The software can only be used in Windows 2000 and Windows XP operating systems. Windows 98 cannot intercept the window keyboard recorder, but cannot be installed in Windows 2003.

Test 2. Window key record software VS nProtect keyboard encryption and Protection Technology

In fact, some software comes with the keyboard encryption technology, such as our commonly used QQ2005 Beta3 version. Test in the same environment, run the window keyboard recorder, open QQ2004, enter the user name and password, and press F12 to call out the window keyboard recorder to view the content, the QQ number and password have been recorded successfully. After the change to QQ2005 Beta3, the Windows keyboard recorder failed to obtain the QQ number and password because QQ has nProtect keyboard encryption and protection technology.

Keyboard Security Summary

For applications without keyboard encryption protection technology, the threat of keyboard recorder is everywhere. To ensure the security of personal usernames and passwords, users should pay attention to the upgrade of the operating system and application software, and try not to use website resources such as online banking in complicated public places (such as Internet cafes. If you do need to use it, we recommend that you first install the secure keyboard and enable the keyboard protection before using it.
