subject: Know The Facts About Keyloggers - Are There Legitimate Use [print this page]

Introduction
Introduction

Keyloggers are used to observe and record all the keys entered by the user

using the keyboard of the computer. It can either be a software program or

hardware device. The person who has set up the device or software will be

able to see all the keys entered by the user. The software program or the

hardware equipment will be able to find even the passwords and other secure

details of the user as it observes and records all the keys entered by an

user. This can help employers to check that their employees utilize the

company computers only for business use alone. The disadvantage of keylogger

is that user details can also be passed on to strangers or used in some

other unethical manner.

Mechanism of Keyloggers

Keyloggers log all the keystrokes. These keystrokes will be stored by a

device or software. Later, it can be manually recovered or automatically

transmitted to someone or a computer. The data is analyzed to find passwords

or other sensitive details that can be used in social engineering or

unethical endeavors. It might also by used to find other details such as

the details of emails sent or chat activity by a computer operator.

Mostly, keyloggers are embedded in rootkits. A keylogger mostly contains two

files: a DLL, which is responsible for all the mechanisms, and EXE, which

packs the DLL and arranges the hook. Few of these logging devices record

screens instead of keystrokes. Some of the advanced loggers will record

information in the form of audio or video and transfer them through the

Internet.

Uses of Keylogger Software

Keyloggers are legitimate software or hardwires that are useful for system

administrators to monitor the activities of the computers under their

control. They are useful for office managers to monitor the activities of

employees on company computers. Installing parental control software which

contain keyloggers help parents to keep track of the website visits and chat

activity of their children. It is also useful for individual users to know

if anything is done on their personal computers when they are not around. In

a cyber cafe, it's useful for the owners to find out what kinds of websites

are used by their customers.

Conclusion:

Keyloggers use a large number of files and their most important use is to

get the information of the user without their knowledge. It can act as a

deterant if employees or family members are aware their activity is beinng

monitord. Of course, it follows that use of keyloggers can be abused for

unethical pursuits, and many may consider them an invasion of their online

privacy.

Be aware that incorrect removal of keyloggers may damage the operating

system, mouse, or keyboard that will make the system unstable. It's best to

remove keyloggers safely using a good quality antispyware program.
