Keyloggers can be an invasion to your privacy. With a keylogger, ALL your typing will be recorded. Someone could install a key logger on your computer and then he will be able to find out EVERYTHING that you have ever typed on your keyboard.
There are so many things to talk about keyloggers. But I have to write this post first because I have received so many emails inquiring about how to detect keyloggers in their computers.
In this post I will talk about how to use KL-Detector and how to interpret the report it creates. For those of you who have never heard of KL-Detector, it is a simple, freeware program I created to detect a keylogger running on your system.
Click here to download KL-Detector
Download the software and run it. You will be presented with some screens. Follow the instructions. After a few minutes, you will get a report from the program.
The difficult part is how to interpret this report.
First, you have to understand what a key logger does. It records your keystrokes and saves it to the hard disk periodically. Based on this principle, it is rather easy to find out whether you have a keylogger on your computer: you simpy have to monitor the hard disk for file writes!
What KL-Detector does is monitoring the hard disk for file writes. The report contains a list of file writes that had been happening during the “test period”. If you do have a keylogger installed, then you will notice a pattern with the file writes. You will notice a file that’s being written repeatedly, in an interval.
To spot this pattern, you have to train yourself. I’d suggest you install a free keylogger on your system and set it to write the log file to a certain location on your hard disk, e.g. C:\keylogger.txt. Then, run the keylogger, and run KL-Detector, and type some random words in Notepad. Then view the report that KL-Detector generated.
You will be able to see “C:\keylogger.txt” in the report, mentioned several times. This is the pattern! Experiment using different keyloggers and after a few tests you will be able to detect a keylogger by yourself.
