Congratulations on your new Key Croc by Hak5! For the best experience, we recommend reviewing the documentation at and checking for software updates at You will find a wealth of knowledge and a helpful community of creative penetration testers and IT professionals on the Hak5 forums at Welcome!

Getting Started

  1. Plug inline between a keyboard and computer.

  2. Type as usual – keystrokes will be recorded.

  3. Press the arming button using a paperclip or SIM card tool. The Key Croc will become a flash drive, and the recorded keystrokes will be saved in the loot folder.

    Next, browse to the KeyCroc flash disk. You will find a config.txt file on the root of the disk, as well as a LOOT folder containing keylog files. Edit the config.txt file to specify key map (keyboard layout/language), as well as SSH, WiFi and other functions. Additional help on using the pattern-matching payloads can be found in the full documentation at
