miniprint

A medium interaction printer honeypot

About

miniprint acts like a standard networked printer that has been accidentally exposed to the public internet.

It speaks the Printer Job Language (PJL) over the raw network "protocol"

Features

• A fully-featured virtual filesystem in which attackers can read and write files and directories - nothing gets written to the host
• Any PostScript or plaintext print jobs sent to the printer will be saved to the uploads/ directory
• Extensive (probably too much) logging
• Shodan Honeycore: 0

Installation

1. virtualenv venv && source ./venv/bin/activate (optional)
2. pip3 install -r requirements.txt
3. python3 ./server.py

Usage

usage: miniprint [-b,--bind HOST] [-l,--log-file FILE] [-t,--time-out TIME] [-h]

       by Dan Salmon: @BLTjetpack, github.com/sa7mon 

optional arguments:
  -b, --bind <host>       Bind the server to <host> (default: localhost)
  -l, --log-file <file>   Save all logs to <file> (default: ./miniprint.log)
  -t, --timeout <time>    Wait up to <time> seconds for commands before disconnecting client (default: 120)

  -h, --help  show this help message and exit

To interactively attack miniprint on localhost, you can use PRET with the following command: python ./pret.py localhost pjl

Logs are generated in format: time - loglevel - method - operation - message and are saved to miniprint.log by default.

Requirements

• Python >= 3.5

Printer Protocol Support

Printer Control Language Support

Page Description Language Support

Known Issues

• PostScript files printed that don't contain %%EOF at the end will cause the printer to wait indefinitely for the end of the job.
