I have written an article about hardware keyloggers for the Hakin9 magazine and thought that some of you might be interested in it. It should introduce the reader into the topic and explains how they work and which countermeasures are possible.

You can find it here.

I have also reviewed quite a few of the products available on the market. Reviews can be found on my website as well.

Feedback is appreaciated.

It's already online, you have to click on Hakin9 - Hardware Keylogger- A serious Threat to open/ download the pdf. Above it says Download.
