Network Scanner Tool (1.0.6)💻

Overview 🛡️

The Network Scanner Tool is a Python-based cybersecurity tool designed to scan networks, detect open ports, banner grabbing, identify running services, and assess potential vulnerabilities. As a beginner, this tool is ideal for network security students and cybersecurity researchers who want to analyze their networks. 🖥️

Features Update in Version 1.0.6 🚀

✅ Fastrer Scan:

• Uses Python's threading library to scan multiple targets simultaneously, reducing scan time significantly.

✅ Stealth Scan:

• Uses a SYN scan (half-open scan) to avoid detection by IDS/IPS.
• The connection is not fully established, making it harder to detect.

✅ Improved Port Scanning:

• Enhanced accuracy in detecting open ports and identifying the services running on them.
• Added support for UDP and TCP port scanning.

✅ Enhanced Reporting:

• Option to export scan results in PCAP, JSON, or CSV format for better analysis and sharing.
• Improved formatting and detail level in reports.

Installation 📥

Prerequisites ✅📦

Make sure that you have installed Python 3.x.y (any updated version) on your system. 📂

py --version

Clone the Repository 🖥️🔗

git clone https://github.com/cobraa9/Network_Scanner_Tool_1.0.5.git
cd Network_Scanner_Tool_1.0.5

Install Required Libraries 📦🛠️

pip install scapy python-nmap argparse

---

Usage 🖥️

Run the tool with the following command and enter your target IP for scanning:

python main.py
 192.168.1.100/24

---

Command-Line Arguments(Optional) 🖥️

Argument	Description
--target	The target IP address or subnet to scan.
--ports	Specific ports to scan (default: common ports).
--stealth	Perform a stealthy SYN scan (to avoid detection).
--threads	Number of threads to use for faster scanning.
--output	Save the scan results to a file (PCAP/JSON/CSV format).

---

Example Commands 🖥️

• Scan a specific IP:

python main.py
--target 192.168.1.100

• Perform a stealth scan on a target IP (or by choosing option 4):

python main.py
192.168.1.100 --stealth

• Scan using multithreading (or by choosing option 3):

python main.py
 192.168.1.0/24 --threads 10

• After the scan if there are any captured packets, save results to PCAP/JSON/CSV(.pcap format recommended for better result analysis)by choosing any prefered option 1, 2 or 3 :

python main.py
 192.168.1.0/24
 1
--output results.pcap

How It Works ⚙️🛠️

1. Device Discovery:
   Uses ARP requests to detect active devices on the network. 🖥️🔍

2. Port Scanning:

   • Uses TCP SYN scans to identify open ports. 🔌🔎
   • Optionally performs UDP scans for additional coverage.

3. Service Detection:
   Uses Nmap integration to identify running services. 🔍📡

4. Stealth Scan:
   Performs a half-open SYN scan to avoid detection by firewalls. 🛡️

5. Faster Scan:
   Scans multiple targets simultaneously, improving scan efficiency.

6. Vulnerability Detection:
   Cross-references detected services with a known vulnerability database.

7. Report Generation:
   Saving Outputs findings in a structured format (PCAP, JSON, or CSV). 📂

Disclaimer ⚠️

This tool is intended for educational and ethical purposes only. While port scanning itself isn't always illegal, but unauthorized scanning of networks that you do not own or have permission to scan is illegal and punishable by law. 🚨⚖️

This is an updated version from my previous project , and Contributions are welcome! Feel free to fork the repository and submit pull requests. 📝

🌟 Future Plans:

👉 GUI Integration: Planning to create a user-friendly GUI using Tkinter or PyQt to improve usability and user experience.
👉 Plugin System: Planning to add support for custom scanning modules.
👉 Advanced Report Generate: Planning to update more features for better packet capturing and result analysis.
