Ruby is a versatile language that is well-suited for developing penetration testing automation tools due to its wide range of libraries and its ability to integrate with other tools. Here are some types of automation tools you can build using Ruby, along with useful libraries and examples:
1. Reconnaissance Tools
Automate the process of gathering information about a target, such as domain information, IP addresses, and public-facing services.
Example Tools:
- Whois Lookup Tool: Use the whois gem to fetch domain registration details.
- DNS Information Gathering: Use the resolv and dnsruby gems to query DNS records and enumerate subdomains.
Libraries:
- whois: For domain lookup.
- resolv and dnsruby: For DNS queries and subdomain enumeration.
require 'whois'
client = Whois.whois('example.com')
puts client.parser.nameservers
2. Vulnerability Scanning Tools
Automate the process of scanning for vulnerabilities in web applications, networks, or servers.
Example Tools:
- Port Scanning Tool: Build a tool to check open ports using TCP/UDP scans.
- Basic HTTP Vulnerability Scanner: Automate checks for common web application vulnerabilities (e.g., SQL injection, XSS).
Libraries:
- socket: For port scanning.
- open-uri & nokogiri: For HTTP requests and parsing responses for vulnerabilities.
require 'socket'
def port_scan(host, port)
begin
socket = TCPSocket.new(host, port)
puts "Port #{port} is open."
socket.close
rescue Errno::ECONNREFUSED
puts "Port #{port} is closed."
end
end
port_scan('example.com', 80)
3. Password Cracking Tools
Develop tools for automating password cracking using dictionary attacks or brute-force techniques.
Example Tools:
- Brute Force Cracker: Automate dictionary attacks for cracking hashed passwords (e.g., MD5, SHA1).
- Rainbow Tables: Implement rainbow table lookups to optimize cracking efficiency.
Libraries:
- bcrypt: For bcrypt hashing and cracking.
- digest: For MD5, SHA1, and other hash algorithms.
require 'bcrypt'
password_hash = BCrypt::Password.create("secret")
puts password_hash
4. Network Sniffing Tools
Monitor network traffic to detect potential security issues, such as unencrypted data or suspicious patterns.
Example Tools:
- Packet Sniffer: Capture network packets and analyze them for unencrypted credentials.
- Man-in-the-Middle Simulation: Automate MITM attacks for testing encryption weaknesses.
Libraries:
- pcapruby: A Ruby binding for libpcap that allows you to capture and analyze packets.
require 'pcapruby'
Pcap.open_live('eth0', 65535, true, 0) do |dev|
dev.each_packet do |pkt|
puts pkt
end
end
5. Exploitation Tools
Automate the exploitation of known vulnerabilities.
Example Tools:
- Exploit Framework: Integrate with Metasploit to automate exploit deployment.
- Reverse Shell: Create a Ruby-based reverse shell for controlled exploitation.
Libraries:
- msf: Use the Metasploit framework from Ruby for exploit automation.
- socket: For creating simple reverse shells.
6. Web Scraping & Information Extraction
Gather sensitive data from web applications, scrape for vulnerabilities, or analyze website content.
Example Tools:
- Crawl Websites: Automate the crawling of websites for potential security issues.
- Form Fuzzer: Automatically submit data to forms to check for flaws.
Libraries:
- nokogiri: For parsing HTML/XML and web scraping.
- mechanize: For automating web interactions (clicking links, submitting forms).
require 'mechanize'
agent = Mechanize.new
page = agent.get('http://example.com')
form = page.form_with(action: '/login')
form.field_with(name: 'username').value = 'admin'
form.field_with(name: 'password').value = 'password123'
page = form.submit
puts page.body
7. Reporting and Logging Tools
Generate detailed reports based on the penetration testing tasks performed.
Example Tools:
- Report Generator: Automate the process of generating HTML/PDF reports for vulnerabilities found.
Libraries:
- erb: For embedding Ruby code in HTML templates.
- prawn: For generating PDF reports
