In some cases, .HKF files pertain to Hardware Keylogger, a device that records keystrokes on a computer for retrieval at a later time. Primarily used for monitoring and surveillance, the HKF file stands for Hardware Keylogger File. When using a hardware keylogger, the exported parts file is saved in the HKF format. To read these files, you typically need to use the proprietary application provided by the manufacturer of the hardware keylogger. For example, Keelog provides software to open the HKF files generated by their keyloggers.
