Commenting on my post entitled My encounter with ransomware “Windows Security Suite,” reader Dragon recommended a nifty program called KeyScrambler.

KeyScrambler takes moments to download and install (although a Premium version is available, the Free version works great) and unobtrusively protects your activity from keyloggers.  Here’s how QFX Software (Key Scrambler’s creators) describe how it works:

KeyScrambler encrypts your keystrokes deep in the kernel, as they enter the computer.

It then decrypts the keystrokes in the destination application, so you see exactly the keys you’ve typed.

Whatever keylogger might be waiting along the crucial path in the operating system has only the encrypted keys – “scrambled” and indecipherable – to record.

The free version of KeyScrambler works with Internet Explorer, Firefox, and Flock.  If you use a different browser, you’ll have to opt for one of the Premium versions.

Here are a couple of screenshots which ought to help you get an idea of what KeyScrambler does:


Although I use a password manager which offers a high level of security, I occasionally find myself manually logging into sites when traveling with my netbook; KeyScrambler will add another layer of security and “stealthiness” ( ! ) to my on-the-road online activity.

Here are a few other facts about KeyScrambler, direct from the QFX site:

    I don’t believe this could protect against a hardware keylogger, though. And, I’d expect that a hardware logger would be pretty commonplace on web kiosks in hotels, at work (if a co-worker is trying to get you), and stuff like that.

    But, for your home computer where the biggest concern is a remote exploit, this could be interesting.
