Do you know what keyloggers is? A keylogger is mainly a programwhich runs in computer silently and secretly recording all the keystrokes ofthe user. They used a method of recording and capturing users keystrokesincluding passwords. Once after the key strokes are logged for the latterretrieval by the attacker they are hidden away. Keyloggers are basically of twotypes, it can be software or hardware based.Hardware based keyloggers are generally more complex that softwarekeyloggers and is much hard to detect. In todays world keyloggers are the mostpowerful applications used for gathering information commonly by encryptedtraffic. There are some features common in all hardware keyloggers, as theyall must have-A non-volatile memory device Nonvolatile memory such as flash memory uses to store all the recorded informationand retains them even when power is lost.A microcontroller It is the heart ofkeyloggers which interrupts the data strea, between the computer and keyboardand posses it and then sends to the memory for storing.Howhardware keyloggers works?Hardware keyloggers are implemented via BIOS level firmware orthrough a device plug-in between the computer and computer keyboard. They haveinbuilt memory which is use to store all the log keyboard activity for laterencryption use. Almost in all cases the recorded data is retrieved by typingsome kinds of special words or special password into a text editor of thecomputer which after detecting by the keyloggers send to the computer toproduce a menu. Apart from producing menu some of the keyloggers provide highspeed download which stimulate the retrieval process of stored data.Hardware keyloggers provides huge storage capacity typical thememory capacity of range of few kilobytes to hundreds gigabytes in which eachkeystroke record consume just a byte of memory space.Types:-Regular keylogger Here keystrokes inlogged in by means of a hardware device attached between computer and keyboardand it is not dependent upon operating system of computer thus does notinterfere any program running on the target machine.Firmware It is a computer BIOSresponsible for handling keystrokes and can be reprogrammed in order to recordkeystrokes and to posses them.Wireless sniffers It collects thepacket of data transferring from wireless keyboard to computer or receiver andthen crack the encryption key in order to make the wireless communicationsecureHardware keylogger supports all sorts of operatingsystem and thus you can use it in any computer at any time. If you are lookingfor a simple and fruitful keyloggers then this will be the best choice for you.Formore information visit:http://www.keydemon.com/
