USB Hack – How to Make Your Own DIY USB Keylogger!

Talk about stealth, this guy has made his own DIY USB keylogger, which is actually USB keyboard adapter with a PIC microcontroller “inside” it as its brains.

Of course, keylogging is probably not legal to do unless you have a good reason like you are an FBI agent spying on suspects/terrorists.

Regardless, knowing how one can make a DIY USB keylogger that is also super-stealth is good to know for your own security that there are smart people out there who can steal your private, personal information.

And who knows, you might need a DIY USB keylogger someday.

Some weeks ago, a friend of mine asked me to help him, cause his computer seamed blocked, indeed, he couldn’t either type his password to login with his account..
I know that he is almost a novice and couldn’t just change the keyboard instead of asking me help, anyway, i changed his keyboard, but I wanted to know why it wasn’t working, I tried it on another computer without any result, except that the keyboard’s leds blinked, so, I wanted to go deeper; I take a Logic Analyzer and i have analyzed the PS/2 protocol, I have discovered that the keyboard was switching off whenever the PC sends 0xFF (Reset) command.. I then solved it simply replacing a capacitor that has blown up.

This is WHY I build it (for any similar case), I’m NOT responsible of ANY aim you use this Keylogger.
Illegal is the WAY you use a Keylogger, not the Keylogger by itself.
I didn’t want to make anything “immoral” or “illegal”
