Hardware keyloggers are used for keystroke logging, a method of capturing and recording computer users' keystrokes, including sensitive passwords. [1] They can be implemented via BIOS-level firmware, or alternatively, via a device plugged inline between a computer keyboard and a computer. They log all keyboard activity to their internal memory.
Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, [1] [2] typically covertly, so that a person using the keyboard is unaware that their actions are being monitored. Data can then be retrieved by the person operating the logging program.
Public computers are extremely susceptible to the installation of keystroke logging software and hardware, and there are documented instances of this occurring. [2] Public computers are particularly susceptible to keyloggers because any number of people can gain access to the machine and install both a hardware keylogger and a software keylogger, either or both of which can be secretly ...
Zeus was used to steal banking information by man-in-the-browser keystroke logging and form grabbing. Like Zeus, the Barbew trojan was initially spammed to large numbers of individuals through e-mails masquerading as big-name banking companies. [ 4 ]
The behavioral biometric of keystroke dynamics uses the manner and rhythm in which an individual types characters on a keyboard or keypad. [4] [5] [6] The user's keystroke rhythms are measured to develop a unique biometric template of the user's typing pattern for future authentication. [7]
Many older computer systems logged keystrokes to a separate storage device, and were capable of rebuilding a days transactions from the keystroke logs and an overnight backup. (I had the dubious pleasure of running this software on a GEAC 8000 when the overnight crashed and the backups had been incorrectly made.)
A backdoor is a typically covert method of bypassing normal authentication or encryption in a computer, product, embedded device (e.g. a home router), or its embodiment (e.g. part of a cryptosystem, algorithm, chipset, or even a "homunculus computer"—a tiny computer-within-a-computer such as that found in Intel's AMT technology).
A gyppo or gypo logger is a logger who runs or works for a small-scale logging operation that is independent from an established sawmill or lumber company. The gyppo system is one of two main patterns of historical organization of logging labor in the Pacific Northwest United States, the other being the "company logger".
