Password-based defense against QQ account theft Trojans

The heart of the victim cannot be possessed, and the heart of the Defender cannot be possessed! Today, when hackers are prevalent, increasing the level of defense is the top priority. However, we cannot just stick to the slogan, but must adopt strict technical means. Taking the most common passwords as an example, how can we prevent both eye-catching and hacker-proof software? This article will teach you a trick to make your password safer!

For the sake of security, the password input and storage in the computer are displayed. In this way, the password cannot be viewed by others. Many users think that it is okay, but the fact is cruel. This password protection method only defends against the gentleman, not the villain. Some people with ulterior motives usually use the remote screen monitoring method and use the password to view the software to easily restore the password. The reality forces us to take more rigorous measures.

We can use a font that cannot be displayed by default as the source character of the password. Take Windows 2000/XP as an example. By default, the text displayed by the system is "" and the character set is "simplified Chinese GB2312 ". If you select characters not found in GB2312 as the password characters (such as the -- character set for installing Office XP), these passwords cannot be correctly displayed, it is displayed as "□"," space ", or"?" And so on, even if you use the password to view the software, this achieves the purpose of preventing hackers from stealing the password. The principle is not complex, but the actual operation also involves a wide range of knowledge.

1. Create password characters

(1) first, use the Office XP "- Character Set" to obtain the password characters. Click Start> All Programs> accessories> System Tools> character ing table. In the displayed window, select-in the font list ". Then pull the scroll bar to the "show CJK extended A" character range (Note: You can see the prompt below the window), select and double-click the character to be used as the password, and then click "copy ", send the password to the clipboard.

TIPS: for the sake of insurance, you can paste these characters into the notepad to confirm that the system cannot display them.

(2) Open the application for password setting and paste the above characters into the Password box. For example, the character 2 can be used as the QQ login password, so that hackers are not afraid to monitor your screen, even if he enables the password to view the software can only see a string? .

TIPS: some websites, forums, or mailboxes do not support using such character files as passwords. Do not use the above method to set passwords.
