DISCLAIMER

• THIS SOFTWARE WAS CREATED FOR AUTOMATED PENETRATION TESTING AND INFORMATION GATHERING. YOU MUST USE THIS SOFTWARE IN A RESPONSIBLE AND ETHICAL MANNER. DO NOT TARGET SYSTEMS OR APPLICATIONS WITHOUT OBTAINING PERMISSIONS OR CONSENT FROM THE SYSTEM OWNERS OR ADMINISTRATORS. CONTRIBUTORS WILL NOT BE RESPONSIBLE FOR ANY ILLEGAL USAGE.

OWASP Nettacker is an open-source, Python-based automated penetration testing and information-gathering framework designed to help cyber security professionals and ethical hackers perform reconnaissance, vulnerability assessments, and network security audits efficiently. Nettacker automates tasks like port scanning, service detection, subdomain enumeration, network mapping, vulnerability scanning, credential brute-force testing making it a powerful tool for identifying weaknesses in networks, web applications, IoT devices and APIs.

Key Features

• Modular architecture - Each task — like port scanning, directory discovery, subdomain enumeration, vulnerability checks, or credential brute-forcing - is implemented as its own module, giving you control over what runs.
• Multi-protocol & multithreaded scanning - Supports HTTP/HTTPS, FTP, SSH, SMB, SMTP, ICMP, TELNET, XML-RPC, and can run scans in parallel for speed.
• Comprehensive output - Export reports in HTML, JSON, CSV, and plain text.
• Built-in database & drift detection - Stores past scans in the database for easy search and comparison with current results: useful to detect new hosts, open ports, or vulnerabilities in CI/CD pipelines.
• CLI, REST API & Web UI - Offers both programmatic integration and a user-friendly web interface for defining scans and viewing results.
• Evasion techniques - Enables configurable delays, proxy support, and randomized user-agents to reduce detection by firewalls or IDS systems.
• Flexible targets - Accepts single IPv4s, IP ranges, CIDR blocks, domain names, and full HTTP/HTTPS URLs. Targets can be mixed in a single command or loaded from a file using the -l/--targets-list flag.

Use Cases

• Penetration Testing
  Automate reconnaissance, misconfiguration checks, service discovery, and vulnerability scanning to support efficient and repeatable penetration testing workflows.

• Recon & Vulnerability Assessment
  Map live hosts, open ports, services, default credentials, and directories, then perform credential brute-forcing or fuzzing using built-in or custom wordlists.

• Attack Surface Mapping
  Discover exposed hosts, ports, subdomains, and services quickly using built-in enumeration modules—ideal for both internal and external assets.

• Bug Bounty Recon
  Automate and scale common reconnaissance tasks like subdomain enumeration, directory brute-forcing, and default credential checks to speed up finding targets.

• Network Vulnerability Scanning
  Efficiently scan IPs, IP ranges, or entire CIDR blocks or all subdomains of the organisation in parallel using a modular, multithreaded approach for large-scale network assessments.

• Shadow IT & Asset Discovery
  Use historical scan data and drift detection to uncover unmanaged or forgotten hosts, open ports/services, and subdomains appearing over time.

• CI/CD & Compliance Monitoring
  Integrate Nettacker into pipelines to track infrastructure changes and detect new vulnerabilities via stored scan history and comparison features.

Quick Setup & Run

CLI (Docker)

# Basic port scan on a single IP address:
$ docker run owasp/nettacker -i 192.168.0.1 -m port_scan
# Scan the entire Class C network for any devices with port 22 open:
$ docker run owasp/nettacker -i 192.168.0.0/24 -m port_scan -g 22
# Scan all subdomains of 'owasp.org' for http/https services and return HTTP status code
$ docker run owasp/nettacker -i owasp.org -d -s -m http_status_scan
# Display Help
$ docker run owasp/nettacker --help

Web UI (Docker)

$ docker-compose up 

• Use the API Key displayed in the CLI to login to the Web GUI
• Web GUI is accessible from your (https://localhost:5000) or https://nettacker-api.z3r0d4y.com:5000/ (pointed to your localhost)
• The local database is .nettacker/data/nettacker.db (sqlite).
• Default results path is .nettacker/data/results
• docker-compose will share your nettacker folder, so you will not lose any data after docker-compose down
• To see the API key in you can also run docker logs nettacker_nettacker.
• More details and install without docker https://nettacker.readthedocs.io/en/latest/Installation
