Everything You Need to Know About Keyloggers

What are Keyloggers?

The word "Keylogger" is quite self-explanatory, but in case you haven't figured out, it's a malicious program that records keystrokes. These recorded keystrokes are then transmitted to the attacker (whosoever has planted the keylogger onto the victim's device). The attacker may then extract valuable information such as usernames, passwords, bank account numbers, personal messages etc.

Keyloggers can be either hardware or software, the latter being more popular. Despite being first used in typewriters in the early 1970s, they are still widely used today to steal information. A research carried out by cyber security experts indicated that keylogging was the sixth most common type of malicious attack used in industrial attacks, worldwide, in the year 2015.

How do you detect Keyloggers?

Most Keyloggers can be detected and removed by popular anti-virus programs such as Malwarebytes, Bitdefender Anti Rootkit etc. but unfortunately that is not always the case. In some circumstances, such as when installing third-party software, you might give a malicious program attached to the software administrative privileges by accident and it may then disable your anti-virus protection. This will render your anti virus protection useless and the keylogger will function at its best. 

The simple solution to this problem is to never disable your anti-virus, irrespective of what the circumstance might be. But, there is also an alternate way to find out if a computer is under the vicious spell of a keylogger.

How to Detect Keyloggers without an Anti-Virus

For times when your anti-virus might not be functioning, as discussed above, the following tips may come in handy.
  • Turn off all external connections to your device. This means disable your internet connection, disconnect your LAN cable and switch off your router and/or modem. This will prevent the keylogger from sending your keystrokes to the attacker while you try to get rid of it.
  • Press Windows+R keys, and then type msconfig in the textbox and hit Enter. Choose the Startup tab and disable all the unfamiliar programs. Then reboot your computer.
  • Next, check the list of programs installed on your computer. Get rid of any programs that you don't remember installing. Some of these programs might be pre-installed; If any programs are vital to your system, your computer won't allow you to get rid of them so don't worry.
  • Press Control+Alt+Delete and select the task manager from the menu.Go to the processes tab and look through the list. Terminate all processes that appear fishy. You will have to use your own intuition here. If you find two processes with the name winlogon.exe, then you can be sure that there is something wrong. End only the second winlogon.exe process.
