PRETty : “PRinter Exploitation Toolkit” LAN Automation Tool

PRETty is useful when a large number of printers are present on a network. Instead of scanning, logging, and manually running PRET against each individual printer, it will automatically discover and run chosen PRET payloads against all printers on the target network.

Additionally, it can be used to automate command/payload delivery to any given list of printers.

  • However, you can place custom IP lists in PRETty/IP/
• It comes with pre-made command list files for PRET located in PRETty/commands/
  • However, you can place additional command list files in PRETty/commands/

Usage

• Run it with ./PRETty.py and follow the prompts 😀
• For more advanced users, run ./PRETty.py -h
  • ./PRETty.py --cli enables CLI mode. (No user input required)
  • The default ./PRETty.py --cli will scan the current LAN, and run ./commands/pret_pagecount.txt on every printer found
  • (optional) Additional arguments are: -r [IP range to scan] -c [Name of command list file to use] -s [PRET shell type]
