of the Keylogger spyware programs
Perhaps you have already heard of keylogger's bad reputation? Well, it's true. The
keylogger is perhaps one of the most dangerous spyware programs that can do a lot of damage to you as a person via
your personal information, as well as your computer. It can be both software and hardware based. We examine both
keylogger spyware versions here.
Keylogger records your keystrokes
A keylogger is a program that runs in your computer’s background secretly
recording all your keystrokes. Once your keystrokes are logged, they are hidden away for later retrieval by the
attacker. The attacker then carefully reviews the information in hopes of finding passwords or other information
that would prove useful to them. For example, a keylogger can easily obtain confidential emails and reveal them to
any interested outside party willing to pay for the information.

computer and going online,
it can become a dangerous instrument for keylogger spyware attack.
Keyloggers can be either software or hardware based. Software-based keyloggers are
easy to distribute and infect, but at the same time are more easily detectable. Hardware-based keyloggers are more
complex and harder to detect. Unless you acquired your computer from a reputable source, for all that you know,
your keyboard could have a keylogger chip attached and anything being typed is recorded into a flash memory sitting
inside your keyboard. Keyloggers have become one of the most powerful applications used for gathering information
in a world where encrypted traffic is becoming more and more common.
Keylogger is difficult to detect
Keylogger secretly records all your keystrokes, thus exposing your
private and confidential information to potential attackers
As keyloggers become more advanced, the ability to detect them becomes more difficult. They can violate a user’s
privacy for months, or even years, without being noticed. During that time frame, a keylogger can collect a lot of
information about the user it is monitoring.
A keylogger can potential obtain not only passwords and log-in names, but credit card numbers, bank account
details, contacts, interests, web browsing habits, and much more. All this collected information can be used to
steal user’s personal documents, money, or even their identity.
A keylogger might be as simple as an .exe and a .dll that is placed in a computer
and activated upon boot up via an entry in the registry. Or, the more sophisticated keyloggers, such as the Perfect
Keylogger or ProBot Activity Monitor have developed a full line of nasty abilities including:
- Undetectable in the process list and invisible in operation
- A kernel keylogger driver that captures keystrokes even when the user is
- A remote deployment wizard
- The ability to create text snapshots of active applications
- The ability to capture http post data (including
- The ability to timestamp record workstation usage
- HTML and text log file export
- Automatic e-mail log file delivery
Authorities' use of keylogger
All keyloggers are not used for illegal purposes. A variety of other uses have
surfaced. Keyloggers have been used to monitor web sites visited as a means of parental control over children. They
have been actively used to prevent child pornography and avoid children coming in contact with dangerous elements
on the web. Additionally, in December, 2001, a federal court ruled that the FBI did not need a special wiretap
order to place a keystroke logging device on a suspect’s computer. The judge allowed the FBI to keep details of its
key logging device secret (citing national security concerns). The defendant in the case, Nicodemo Scarfo Jr.,
indicted for gambling and loan-sharking, used encryption to protect a file on his computer. The FBI used the
keystroke logging device to capture Scarfo’s password and gain access to the needed file.
