== Operation ==
It provides 3 modes of operation: Off, Arming, and Attack. In attack mode, the Shark Jack will execute the payload.sh or payload.txt bash script from the /root/payload directory. In arming mode, the Shark Jack will be configured with a static IP address of 172.16.24.1 and will simply start an SSH server, without automatically executing any script. In this mode, a perpetrator may load and configure scripts, or retrieve output files placed in the loot directory from previous reconnaissance or attack operations. This can be done using the Linux command line utility “scp”. The status LED lights are configurable using appropriate syntax inside the payload script, provided by the Shark-Jack firmware.
== Example Usage ==
The user prepares a payload script which performs basic network auditing. Here, the user obtains an IP address via DHCP. The DHCP flow is initiated using the "NETMODE DHCP\_CLIENT" directive provided by the Shark Jack framework. Once an address is assigned, grep and sed is used to perform text manipulation on the output of the "ip addr" command, in order to filter the subnet. This subnet is then passed as a argument to nmap. A simple nmap with the option "-sn" is performed. This means that port scans and other elaborate scans are skipped. It is a fast way to determine available hosts. Additionally, a traceroute to Google servers is used to gain further insight into the network topology. The outputs of nmap and traceroute are appended to a loot file:
  #!/bin/bash
  LED SETUP
  NMAP_OPTIONS="-sn" LOOT_DIR=/root/loot/net
  mkdir -p $LOOT_DIR
  echo "Obtain IP address..." >> SLOOT_DIR/log.txt
  NETMODE DHCP_CLIENT
  while [ -z "$SUBNET" 1; do
  sleep 1 && SUBNET=$(ip addr | grep -i eth0 | grep -i inet | grep -E -o" ( [0-91{1,3}[\. 1) {3710-91{1,33\/1{1}[0-91{1,23" | sed 's/\.[0
  9]*\//\.01 //')
  done
  echo "Obtained IP address in subnet: $SUBNET" >> $LOOT_DIR/log.txt
 
  LED ATTACK
  echo "Starting nmap with options §NMAP_OPTIONS" >> $LOOT_DIR/log.txt
  nmap SNMAP_OPTIONS $SUBNET -ON SLOOT_DIR/net-scan.txt echo "Starting traceroute >> SLOOT_DIR/log.txt
  traceroute 8.8.8.8 > SLOOT_DIR/net-scan.txt
  echo "Done" >> $LOOT_DIR/log.txt
  echo "Inspect loot under SLOOT_DIR/net-scan.txt" >>
  $LOOT_DIR/log.txt

Description

Portable network attack tool, fast nmap scans. The Shark-Jack is a pen-testing utility developed by the ”Hak5” company and is designed for Ethernet plug and play vulnerability scanning in LANs. In its most basic form, it is essentially a small Linux-machine with a built-in Ethernet plug. The modest, portable physical nature of the device allows for quick and secretive reconnaissance activity. The Shark-Jack consists of following physical components: USB-C charging port, Battery, Status LED, RJ45 Ethernet Jack, MT7628DAN Mikrocontroller, 64 MB RAM, Casing with mode-switch.
