Pillage Information

Understand your target environment

For anyone who clicks we'll gather as much information as possible, you set how aggressive you want to be. Once they click the link they'll see a legitimate site, or be sent to your own server, whichever you choose. At the same time they're engaged in the innocuous website Black Squirrel will be collecting:

  • IP addresses for all their adapters
  • Browser plugins
  • Other host's IP addresses on their internal network
  • Fingerprinting other hosts in the network
  • Any custom actions you add

All done through the victims browser without any special privileges required.

Custom Payloads

Extensible, for the true hacker

Build your own plugins for custom fingerprinting or exploits. You can write Javascript plugins which uses the Black Squirrel framework to do things like find all TP-Link routers, attempt credentials, and on success execute a command to send you a reverse shell.

Beyond spearphishing, you can also include BlackSquirrel as your payload for cross site scripting or any other client side attacks.
