What Is A Keylogger?
What is a keylogger? With
so much being discussed about keyloggers, keystroke loggers or
keylogging software on the same lines as data theft, it's an obvious question.
keylogger can be a software application or a hardware device that
silently monitors, intercepts and records the keystrokes made on a
particular computer's keyboard. Generally keylogging happens without
the computer user's knowledge.
Typically this happens as part of
strategy to be able to spy on anyone or to steal sensitive
information including but not limited to login credentials, personal
information such as bank access details, credit card information
that's being entered on the computer.
Various Types of Keyloggers
that we know what is a keylogger, let us look at the three primary
categories of keyloggers.
- Are often invisible programs that silently run in the background
of a PC and record every keystroke, some are sophisticated enough to
even capture autocomplete passwords. The recorded information saved
in a file and is stored on the hard drive or have feature to email
to a configured email address. These programs can also perform
screen captures. Software
keyloggers while at their work may be visible in the task manager or
be invisible as stealth keyloggers.
– Are small devices placed between the keyboard and the PC, some
may even be fitted internally inside the keyboard. They can often go
undetected either because of their size or even impossible to detect
if placed inside a keyboard. While they are absolutely capable of
capturing hundreds of keystrokes, they may not even use the
computer's storage. Hardware-based are more difficult to implement
on the target machine as they keyloggers are less common, as they
often require physical access to the target computer. They are
completely undetectable to malware scanners and may only be detected
by hardware experts.
– Implemented at the kernel level, these types of keyloggers
receive data directly from the keyboard by either piggybacking on
the driver software or by replacing the core software responsible
for interpreting keystrokes. While they may be undetectable by most
security software it may not be possible to record autocomplete
passwords with these keylogging applications.
