Know The Facts About Keyloggers - Are There Legitimate Use
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.
