Things you should know about keylogger

What Is A Keylogger?

A keylogger is a type of surveillance software that has the capability to record every keystroke you make to a log file, usually encrypted. A keylogger recorder can record instant messages, e-mail, and any information you type at any time using your keyboard. The log file created by the keylogger can then be sent to a specified receiver. Some keylogger programs will also record any e-mail addresses you use and Website URLs you visit. Keyloggers, as a surveillance tool, are often used by employers to ensure employees use work computers for business purposes only. Unfortunately, keyloggers can also be embedded in spyware allowing your information to be transmitted to an unknown third party.

Where is a keylogger used?

A keylogger is basically used in corporate firms to allow employers to ensure employees use work computers for business purposes only, or by protective parents, or jealous spouses, or Information Technology (IT) organizations to troubleshoot technical problems with computers and business networks. Keylogging can also be used to study human-computer interaction. Even Microsoft publicly admitted that Windows 10 operating system has a built-in keylogger in its final version “to improve typing and writing services.” However, a keylogger can also be installed in a spyware by hackers that would allow them to steal passwords, credit card information and other credentials from public computers.

Features of a keylogger:

Keylogging software runs hidden in the background, making a note of each keystroke you type. However, a keylogger when installed on a device can generally do the following:

  • Capture any passwords entered by users on the device

  • Anything that has been copied to the clipboard is captured by the software.

  • Take screen captures of the device at periodic intervals

  • Record the URLs that were visited via Web browsers, and possibly also take screen captures of the Web pages viewed

  • Record a list of the applications run by users on the device

  • Capture logs of all instant messaging (IM) sessions

  • Capture copies of sent emails

  • Automatically send the reports containing stored logs and emails to a remote location (by email, FTP or HTTP).

 

Where Keyloggers Come From and How to Determine if Your Device Has One?

Some keylogger software is freely available on the Internet, while others are commercial or private applications. Keyloggers are sometimes part of malware packages downloaded onto computers without the owner's knowledge. Detecting the presence of one on a computer can be difficult.

By design, they hide their presence on a system via methods such as

  • being installed in hidden directories (folders) on the target system
  • cleverly disguising or hiding the application from the operating system task list (Windows Task Manager and Start screens, Mac OS Activity Monitor, and equivalent)

So-called anti-key logging programs have been developed to thwart keylogging systems, and these are often effective when used properly.

 

How to remove a keylogger from your computer?

If you suspect that your computer has a keylogger, you can try any one of the below tricks:

  • Begin by running your antivirus, which can often detect a keylogger on your system.

  • Run a program like Spybot Search and Destroy or Malwarebytes to check for certain types.

  • Check your task list by pressing ctrl+alt+del in Windows. Examine the tasks running, and if you are unfamiliar with any of them, look them up on a search engine.

  • Scan your hard disk for the most recent files stored. Look at the contents of any files that update often, as they might be logs.

  • Use your system configuration utility to view which programs are loaded at computer start-up. You can access this list by typing "msconfig" into the run box.

 

How to protect my computer from a keylogger?

First and foremost, be careful of what you download and run. Ensure that your operating system, software products, and Web browsers are up-to-date with the latest security patches. And finally, it is very important to install a good anti-spyware product or a complete Internet security solution that prevents against keylogging malware from running on your computer.
