Setting a new standard

The KeyGrabber Forensic Keylogger is a record-breaking USB hardware keylogger in terms of size, keyboard compatibility, and price. It measures only 0.4" (10 mm) in length, and can be accessed as a USB flash drive for instant data retrieval. It's by far the most miniaturized and discreet hardware keylogger available on the market. Completely transparent for computer operation, cannot be detected by computer software. The KeyGrabber Forensic hardware keylogger features a sophisticated FPGA chip with a 32X oversampling algorithm, making it compatible with all types of USB keyboards and barcode readers. It's also an advanced penetration testing tool, with a built-in scripting language.

KeyGrabber Forensic Keylogger - Applications


KeyGrabber Forensic Keylogger - Size

Record-breaking size

The KeyGrabber Forensic Keylogger is intended to be a professional security and surveillance tool. The record-breaking size of just 0.4" (10mm) ensures full discretion and minimizes the risk of exposure. This hardware keylogger is the end-of-the-line in terms of form-factor miniaturization, as the size is only limited by the physical dimensions of the USB socket and plug.


Passively monitoring a USB bus for keystrokes is a complex task, and the KeyGrabber Forensic Keylogger does this better than any other solution on the market. The KeyGrabber Forensic Keylogger implements a 32X waveform oversampling algorithm based on a sophisticated FPGA chip. This makes it a top-performer in terms of reliability, with a zero character drop-rate. It works with wireless keyboards (excluding some Bluetooth models), keyboard with integrated hubs, and all types of barcode scanners (including those with a fast keystroke generation speed).

KeyGrabber Forensic Keylogger - Ease of use

Ease of use

The KeyGrabber Forensic Keylogger is as easy to use as all it's predecessors in the KeyGrabber family, being best-sellers since 2005. This hardware keylogger works out-of-the-box by simply plugging it inline between the keyboard and USB socket. Accessing data requires pressing a predefined key-combination known only to the owner. The KeyGrabber Forensic Keylogger has a few models varying by memory capacity, however even the entry-level 16 megabyte version is an equivalent of years of typing.


The KeyGrabber Forensic Keylogger is as stealthy as a hardware keylogger can get. It leaves no traces on the target computer, and doesn't propagate anything in the local Wi-Fi environment. It works as a passive USB-tap device, and doesn't show up on the list of USB devices or use any drivers. Thus it cannot be detected by security and anti-virus software.

KeyGrabber Forensic Keylogger - The Pro version advantage

The Pro version advantage

The Pro version is a multi-role security and pen-testing device. It works as a keylogger, but can also be switched to keystroke generation mode. Operating as a HID device it can generate a text-menu, making access to memory and configuration options more convenient. However, it can also run keystroke-injection scripts thanks to a keystroke parser based on a simple scripting language. This makes it a perfect penetration testing tool, combining the functionality of a hardware keylogger and HID injector in a single slick device.
