What is Keyloggers ? How to detect and remove Keylogger, how to remove keylogger, types of keyloggers,

A keylogger is a software program or hardware device that runs in the
background, recording all the keystrokes. Hackers use keyloggers to steal
personal or financial info like bank details, which they can then sell or
use for benefits.

Keylogger Definition

Keylogger is a software or hardware device which is used to monitor
and store each of the keys a user types into a Laptop or computer keyboard. 
The user who installed the program can view all keys that are typed by the user
because these programs and hardware monitor the keys typed in a user can find
easily the user’s password and other sensitive data a user never wish to other know
about that information.
Keyloggers are often used by companies to ensure employees use computers for
business purposes only. But unfortunately, keyloggers can also be embedded in
spyware allowing your information to be transferred to a third party.

About Keyloggers

A keylogger is a software program or hardware device that runs in the
background, recording all the keystrokes. The attacker/hacker can use this
information for finding passwords, or possibly other useful information that
could be used to compromise the system or be used in another social engineering attack. 
For example, a keylogger will reveal the contents of all emails composed by the
user. Keylogger is commonly included in rootkits.
A keylogger generally consists of two files: DLL and Exe:  a
DLL which does all the work and an EXE which loads the DLL file and sets the
  • Some keylogger capture screen, rather than a keystroke.
  • Another keylogger will secretly turn on video or audio recorders, and
    transfer what they capture over your internet.

How to Keyloggers Work 

Keyloggers collect information about the victim and send it back to a third
person/party – whether that is a criminal or IT department. The amount of
information collected by keylogger software can be different. Basic forms may
only collect the information typed into a site or app. 
More complicated ones may record everything you typed no matter the
application, including information you copy & paste. Some types of
keyloggers record information such as calls, information from
messaging applications, location, screengrabs, and microphone and camera
phone capture.
Data collected by keyloggers can be sent back to hackers by email or uploading
data to predefined sites, databases, or FTP servers. If the keylogger comes
bundled within a  big attack, actors might simply remotely log into a
machine to download data.

How To Detect And Remove Keyloggers

  • There are many types of keyloggers that use different techniques. Keyloggers can manipulate the OS kernel and a task manager is
    not enough to detect keyloggers. 
  • Security software like anti-keylogger programs is designed to scan software-based keyloggers by comparing files against keyloggers. Using anti-keylogger is more effective than antivirus or other security software.
  • Disable self-running files on externally connected devices such as USBs
    and restricting the copying of files to and from external to computers may also
    reduce the possibility of infection.
  • Virtual screen keyboards reduce the chance of being keylogged as they input
    information in a different way to a physical keyboard.
  • The best way to stay safe is that their password policy is multi-faceted and
    that two-factor authentication is implemented across company accounts and
