All You Need to Know About Keylogger Malware
Malware (abbreviation for MALicious SoftWARE) is a major threat in our increasingly connected world. It is any program formed with the intention of causing harm to a computer system.
Malware include viruses, worms, Trojans, keylogger, spyware, adware. Even SPAM might be considered to be linked with malware, though not be malware itself, since SPAM is the way by which hackers upload other kinds of programs onto your system.
What Is A Key Logger Malware?
The expression keystroke logger, or key logger for short, has come to be connected chiefly with its use as an illegal or malicious tool set up to furtively capture all of the keystrokes typed on your machine. The truth is that, like many malevolent hacker tools, keystroke logging has its beginnings as an administrative and diagnostic tool. This is a classic example of how some of the most supportive tools and utilities can end up being used for all the wrong reasons.
A key logger is a hardware product or software utility that observes every keystroke typed on the computer. It may simply log the keystrokes and need someone to physically recover the data. It could also be designed to automatically send the gathered key logger information to an e-mail id.
Hardware Keyloggers
Hardware keystroke loggers are typically a machine of some kind that is plugged into the computer and the keyboard. A careful user would be able to visually examine and track a key logger such as this. But, some hardware based key loggers are built into the keyboard in a more careful manner and thus can remain unnoticed.
Software Keyloggers
A software keystroke logger usually consists of two files: a DLL which does all the work and an EXE which loads the DLL. Simple key logger malwares are often invoked at boot via a registry entry. The more sneaky versions are unseen in the process list, and can function at the core level and leave invisible registry entries. The most widespread technique of getting infected with a key logger is through spyware or rootkits.
You must be very careful not to type sensitive or private information on any public system such as a kiosk or public library computer system. As for your own personal computer, or computers in a corporate network environment, it is imperative to install antivirus and anti spyware software and keep it efficient. These security programs can sense and remove known key logger programs. There are precise anti-key logger programs that are easily available.
