A 'keylogger' is a piece of software which secretly records every keystroke that is typed, while running in the background on a computer. Most keyloggers cost a lot of money, however, there is a free program called 'Shadow Keylogger'. In this instructable, I will explain how to load this freeware keylogger onto a flash drive, and deploy it on any computer easily and quickly. Assuming you already have a flash drive, creating this keylogger won't cost anything.
It is important to note that in some countries, including the U.S., covertly intercepting electronic information is against the law. This guide is therefore intended to instruct you on how to use a keylogger on your own computer.
