Keyloggers

Keylogger is hacker’s and script kiddies’ favourite tool. Keylogger is a software which records each and every keystroke you enter including mouse clicks. Hardware keyloggers are also available which will be inserted between keyboard and CPU. It hardly takes a minute to install this software/hardware in victim’s system and from next second onwards attacker will get each and every activity going on victim’s computer. What they are chatting, which site they are browsing, victim’s username, passwords what’s not? Each and every activity happening in victim’s system with screenshots will be recorded. This activity will be saved on victim’s system or it can be mailed to attacker’s email.

Let’s see how attackers do this along with protection techniques

Hardware keylogger: This is a thumb size device. It records all the keystrokes you enter from the keyboard then saves it in its memory. Later this data will be analysed. The drawback of this device is that it can’t record mouse clicks, can’t take screenshots and even can’t mail and it requires physical access to the machine.

Software keylogger: This can be installed in victim’s system even if they use updated antiviruses. There are a lot of softwares available in market which make a keylogger undetectable by latest antiviruses.

How to fool a keylogger?

Yes we can fool a keylogger. Keylogger’s job is to record all the key strokes we enter. So to fool a keylogger, enter unnecessary keys along with passwords. Confused?

Say your password is 1234. Now how will you enter it. Enter 1 then any unnecessary character say jksfh then 2 then again "£%mygb then 3 then &^%% then 4 then £fsg$^ then 5. Now remove unnecessary characters.

If it is a Hardware Keylogger use Onscreen Keyboard. To open this go to run and type “osk”.
