Keyloggers – The Good, The Bad and The Ugly

Man Being Arrested by 2 Policemen-arrested-by-policeWhenever I travel, I am extremely reluctant to use the hotel’s computers – you know, the ones that they allow you to use free at the hotel lobby; even those located in business centers. All because I fear a keylogger that may be planted in the machine.

Keyloggers come in 2 forms; software or hardware. A software-based keylogger, as the term suggests, is a program that logs every keystroke of the keyboard. Some software periodically captures the screen instead of logging keystrokes. A hardware-based keylogger on the other hand is a device that is attached between the keyboard and the computer (like a dongle) to again capture all the keystrokes the unsuspecting victim enters. Alternative to the dongle method are micro-chips that are embedded directly into the keyboard itself to record activities.

Generally, keyloggers are used for malicious intents. Mainly to capture passwords and codes of victims; bank accounts, credit card information, passwords to sensitive information, etc. I’m pretty sure you know how the information thieves are going to use the captured information.

There are those who put keyloggers to good use (using screen capturing keylogger tools). Such are the examples of employers who wants to keep a tab on their employees; to ensure that their workers are not spending too much time being unproductive. Even so, there is an ethical consideration for employee privacy. This tool will also be very useful for parents to keep an eye on their children especially those spending much time online. Of late, with so many news of sex fiends preying online, I won’t be surprised if parents rush to get this tool installed.

This blog post’s last words; it pays to be on the side of caution.

    I can also add that the only way to enter the information safely on a pc, that has a hardware keylogger is not to use physical keyboard. The only way is to use virtual keyboard(the one, where you place key clicking on them by your mouse cursor) What is also important is that this virtual keyboard should be a part of special anti-keylogging protection i.e. it should protect both against hardware and software keyloggers. If you are interested in anti-keyloggers can recommend to visit this site: http://www.anti-keylogger.org

    I used these ‘free’ computers services to do everything that do not require me to enter any personal info. I surf the net, read news, watch Youtube, etc. We need to be creative to find ways to maximize the use of what’s free for us 🙂
