Summary

The Shark Jack display is an Ethernet-connected device that runs selectable payloads for network and port scans, LLDP discovery, and connectivity checks. Two devices can use Shark Link to validate network paths and configurations.

Key points

  • The Shark Jack display is described as a pocket-sized Ethernet network reconnaissance tool with a screen and selectable on-device payloads.
  • Payloads can run Nmap scans, enumerate targets, scan ports, and discover network information using LLDP.
  • The device can help administrators check whether a wall jack is active, identify its network connection, and test IP address and internet connectivity.
  • A payload called Shark Link lets two devices test connectivity between network locations and validate ACL, firewall, and VLAN configurations.
  • The device runs Linux-based payloads using Bash and Ducky Script commands, including interactive menus.
