In our last blog, we looked at spyware and how it could sneakily record everything you did on your computer. Today’s we’re looking at keyloggers, a variation of spyware with a very specific way of tracking.
What’s a keylogger?
- Like spyware, a keylogger is designed to work covertly with malicious intent, but instead of potentially tracking everything, it tracks and logs the keystrokes on your keyboard.
What information is it looking for?
- A keylogger’s aim is to obtain sensitive information that may be typed into your computer – that’s your credit card information, passwords, and other personal information.
- Keyloggers can be software that is downloaded without a user’s knowledge but can also be present in the form of a piece of hardware connected to the PC such as a memory stick.
A real-world example:
- Banks fully understand the severity of keyloggers and the threat they can pose to their clients. Most online banking websites now ask you to only enter certain characters of a password so that in the event of a keylogger working in the background, they will only get 2 or 3 letters.
How can I prevent this?
