Hi all friend, this time Johan Computer will share some of the things I know about a software called keylogger.

One of the widely used hacking techniques to take over confidential data on someone's computer without the computer owner's consent authority (administrator).

Shortly after a keylogger be installed on the computer, the program will run every computer restart and difficult to be detected.
