Key Croc

Beschreibung

Hak5 Key Croc is a smart keylogger and penetration-testing implant for authorised engagements. It can pass keyboard input through to a host while recording keystrokes, monitor for defined key sequences and run an approved payload when a matching pattern is entered. Use it only on systems and accounts where testing has been explicitly authorised.

Key features

• Passes keyboard input through to the target while saving keystrokes to a log file.
• Pattern-matching payloads can trigger when a defined key sequence is entered.
• Supports HID, Ethernet, storage and serial attack modes.
• Can emulate a connected keyboard and clone its hardware identifiers in keyboard attack mode.
• Provides a Linux root shell for authorised security testing and research.
• Supports remote management capabilities and web-based payload development through Hak5 tools.
• A configuration file allows settings such as keyboard layout, Wi-Fi, SSH and DNS to be edited with a standard text editor.
