Shark Jack firmware may be updated by using the sharkjack.sh helper script. That said, it is also possible to manually upgrade the firmware by following this process:

  1. Download the latest UPDATE file from https://downloads.hak5.org/shark and verify its checksum.
  2. Power on the Shark Jack in Arming Mode and connect it to a reliable USB power source
  3. Copy the file upgrade file to the Shark Jack’s /tmp directory via SCP (e.g. “scp upgrade-1.1.0.bin root@172.16.24.1:/tmp/”)
  4. SSH into the Shark Jack (e.g. “ssh root@172.16.24.1”)
  5. From the Shark Jack’s bash prompt, issue the sysupgrade command relevant to your firmware update file (e.g. “sysupgrade -n /tmp/upgrade-1.1.0.bin”)
  6. Wait 5-10 minutes as the Shark Jack flashes the firmware and reboots.
