How to fool a keylogger ?
Keylogger is a device that capture keystrokes pressed by user and logs it for futher use.
Parents can check which keys they children pressed to make sure they didn’t access the forbidden web pages.
Malicious people can try to read recorded security passwords and use them to get the unauthorized access to your data.
So, what to do if you have to log into your account, but you suspect the keylogger sniffing every key you press ?
Use mouse.
If you have graphic interface to input the password, you can use mouse support in various ways, that you are probably familiar from your text editor.
1) while typing move the position of input cursor with the mouse, that will alternater the order of inputed keys
2) type a fake text, then select it with the mouse and overwrite with proper password
3) open some prewritten text in another window and with the mouse select, copy/paste the letters without using the keyboard.
Here is the example:
Our secret word is ’shark’, and it is a part of email we need to enter.
1) input the letters ‘arregyurty5×39‘, where ‘ar‘ is the part of the password and the rest is some random strokes text
2) select the dummy text with the mouse
3) input letter ‘k’ that overwrites dummy, now you have ‘ark’
4) move the cursor with mouse to front
5) type ’sh’
Now in the input box you should have ’shark’ , but
keylogger recorded string ‘arregyurty5×39ksh’ and even when all your password letters were recorded it is very hard to guess the pass from it.
You have fooled the keylogger !
In similar way you can input the rest of your secret data to the boxes from the example, and safely logg in.
This method will work against most of known keyloggers, but what if the brand new keylogger records also mouse movement?
Allways be more carefull that is obvious.
