What is Keylogger?
A Keylogger is a software program or a hardware device created to capture every keystroke that the user makes. A Keylogger is a malware, which belongs in the spyware family.
A Keylogger logs every single website you visit, every email you send and receive, every document you create, etc. Basically, a Keylogger captures every number, letter or a symbol typed on a keyboard.
Sometimes, Keylogger is used for legitimate purposes. For example, an employer may use a keylogging program to monitor its employees’ online activities; or a parent trying to monitor child’s online activities; or law enforcement trying to gather some evidence.
However, most Keylogging programs are malicious and their sole purpose is to gather victims’ sensitive information such as passwords, user names, credit card numbers, bank account numbers, social security numbers, and other confidential information.
Keyloggers can be either a software program or a hardware device.
Software Keylogger captures data and then sends it to the person responsible for the installation of the keylogging software.
Hardware keylogging devices have to be manually connected to the victim’s computer. The keylogging device captures keystrokes and stores them in its own internal memory in a text file.
There is no one good way to prevent a Keylogger; however, here are just a few quick tips to reduce the risk of getting one:
- First of all, use your common sense! Don’t visit questionable websites. Don’t download free/pirated software, movies, music, screen savers, etc.
- Review and monitor which programs and application get installed on your computer.
- Use anti-virus and anti-spyware programs.
- Keep your operating system and all programs up to date.
- Don’t leave your laptop unattended in public places.
- Check the cables that connect your desktop computer with the keyboard periodically for any unusual devices.
