Record mode

Installation of the hardware USB keylogger in record mode is quick and easy. Simply plug it in between the USB keyboard and the USB port. No software or drivers are required. The USB keylogger will automatically start recording all data typed on the keyboard to the internal flash disk.

Hardware keylogger install (1)

Disconnect the USB keyboard from the USB port at the computer or hub. This can be done even with the computer up and running.

Hardware keylogger install (2)

Connect the hardware USB keylogger between the USB keyboard and the USB port. Keystroke logging will start automatically.

Playback mode (Flash Drive)

Once data has been captured in record mode, you can retrieve it on any computer with a USB port. This is done by switching to Flash Drive mode. The USB hardware keylogger and keyboard should be connected in the same way, as in record mode.

USB hardware keylogger Flash Drive mode (1)

Each device has a built-in 3-key combination (by default K, B, S).
Press these 3 magic keys simultaneously to trigger Flash Drive mode. The keylogger will automatically respond as a mass storage device.

USB hardware keylogger Flash Drive mode (2)

The Flash Drive will contain the file LOG.TXT with a text log of all captured data. Keystroke data is formatted in the same as it would appear on the screen, with special keys in brackets ([Ent], [Esc], [Del] etc.). This file can be viewed and searched with any text editor, such as Notepad or MS Word.

Mac Compatibility Pack (MCP)

The Mac Compatibility Pack (MCP) is a hardware enhancement ensuring full compatibility with Apple Mac computers and keyboards. Several Apple keyboards are USB High-Speed and Low-Speed combos, creating a challenge for all types of USB keyloggers. The aluminum Apple A1243 and A1242 are typical examples:

Keyboard - Apple A1243

The KeyGrabber USB with the Mac Compatibility Pack features a special Mac Mode (enabled by default), which will ensure proper operation of the keyboard and logging of all keystrokes. Mac Mode is compatible with standard keyboards too, so the KeyGrabber does not have to be reconfigured.

Does the MCP version work with PCs and non-Mac keyboards? Yes, it does both in Mac Mode, and normal mode. If you are planning to use the KeyGrabber on a PC, the MCP version will work fine.

Does the non-MCP version work with Macs? In most cases yes, but this is not guaranteed. If you are planning to use the KeyGrabber with a Mac, the MCP version is the safe choice.

More details are available in the KeyGrabber USB User Guide.

Configuration options

The USB hardware keylogger may be configured through the file CONFIG.TXT, placed in the Flash Drive root folder. Use any text editor to prepare such a configuration file, containing the following text:

More details are available in the KeyGrabber USB User Guide.

National keyboard layouts

It is possible to enable a national layout for language-adapted keyboards, such as French, German etc. This will allow national characters to get logged properly (including those with Alt Gr), such as ö, ß, ó etc. The following example demonstrates the advantages of applying the German national layout.

Text logged with layoutText logged without layout
Keylogger (PS/2 & USB)Kezlogger )PS-2 / USB=

To enable a national layout, the appropriate layout file named LAYOUT.USB must be placed in the hardware keylogger root folder. The file must be copied in Flash Drive mode (no access to the flash disk in record mode). Layout files may be obtained from the CD-ROM attached with the device or from the download section. The flash disks main folder should contain the file LAYOUT.USB and the standard log file LOG.TXT.

National keyboard layouts

To enable the layout, safely remove the flash disk. On record mode initiation, the layout file will be loaded automatically.
