When we think of keyloggers, we think of them as nasty tools that someone else might use to record every stroke of our keyboard. However, there are some instances where one might have need of such a tool. Granted, most of those situations might still be considered a bit shady by some, but if you need one, you need one. The most important part when making one is to ensure that it won’t be discovered.
This hack shows you how to craft a keylogger that will fit inside a USB to PS/2 adapter. That way, even if someone sees the device, they won’t have any reason to suspect anything. At worst, they’ll simply remove it and toss it aside. Since you’re working in such a tight space, you’re going to need some excellent soldering skills, in addition to the necessary parts. Just remember, when you do craft something such as this, don’t use it for evil.
