A hardware keylogger is widely used as electronic
equipment which is competent enough of acquiring keystrokes from any particular
USB keyboard or a PS/2. The general purpose of hardware logger is to use it
especially for keystroke logging. Keystroke logging is considered to be one of
the most trusted and authentic automatic procedures in which essential and
confidential passwords are recorded safely for future reference. Such passwords
can be put into practice with the help of BIOS-level firmware. A substitute
process can also be implemented by additionally plugging a device in-between
the keyboard and computer.
Mandatory essentials for a hardware logger
One of the biggest advanatage which
hardware keyloggers offer as compared to software keyloggers is that a hardware
keylogger enables you to login as soon as the computer is switched on. This
enables the computer to track down the passwords from the particular disk
encryption software. Few essentials which are mandatory for each and every
keylogger are:
A stable memory device
A memory device which is non-volatile in
nature like the flash memory records the data and information which is stored
even there is no power due to any reason.
Microcontroller
The utility of this device is that it
construes the particular datastream present in the middle of a computer and
keyboard and the progresses it in the stable memory.
Hardware keylogger types
There are 4 basic types of keylogger available
in the market, namely:
Firmware
It the BIOS of a computer which is
accountable for keeping a track of all the keyboard events and it can re-program
in order to record the strokes of the key when processed.
Wireless Keylogger Sniffer
Bundle of information and data can be
shifted from any wireless keyboard and the encryption then can be cracked down
to protect the wireless communication in-between the two equipments.
Keyboard overlays
A fake keyboard is generally put on top of
an original one and hence any key pressed is recorded simultaneously in both
the equipments.
Normal hardware keylogger
It generally logs all the activities of the
keyboard in the internal memory and it can be used by pressing a number of pre-definite
characters. It cannot be detected by any other software and hence adds to its
credentials.
Keylogger is generally used to assist a
