New users can also deal with the virus: Clever password-infected Trojan Horse

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.
2. Password Management

Generally, you cannot directly enter CJK extension characters in the input method. For ease of use, you can use the Word hyperlink function to store or manage passwords. Select "-" from Word XP and paste the Password character into the document. Then add a hyperlink for the character. The link address is QQ program. In this way, the next time you need to change the QQ login password, you only need to click the hyperlink in the document to start QQ, And Then paste the Password character into the Password box. In addition, the Word documents should be encrypted and saved.

3. prevent password cracking

To prevent people familiar with this method from deciphering, you can also use the built-in Location Code Input Method to input text without coding in the system font, in this way, even if you select the 正 character set, the password cannot be displayed normally (only blank spaces are displayed ).

(1) Open the control panel, double-click "region and language options", click "language> details", and select "simplified Chinese (internal code)" in the list of installed services )", click Add to add it to the input method list.

(2) In the need to enter the password, select the internal code input method, enter the encoding between the aaa1-affe (such as aaa2, aaa3 ,......), Because the system Font does not contain these encoding characters, the system displays the characters with spaces. However, since the characters cannot be displayed, it is difficult to change the password again. Remember the entered encoding.
