In the ever-evolving world of cybersecurity, website penetration testing remains a cornerstone for assessing the robustness of web applications. With sophisticated attacks emerging daily, understanding how to effectively test a site’s defenses from reconnaissance to exfiltration is indispensable. This article will walk you through various stages of website penetration testing with a focus on practical, real-world examples and methods used by top professionals in the field.
Introduction to Website Penetration Testing
Website penetration testing, often referred to as web pentesting, involves simulating cyberattacks against web applications to identify security vulnerabilities that could be exploited by hackers. A comprehensive pentest will assess the security of various aspects, including the server, database, network, and client-side scripting vulnerabilities.
Phase 1: Reconnaissance
Passive Reconnaissance
Open Source Intelligence (OSINT): This involves gathering publicly available information about the target. Tools like Maltego and Shodan can be quite effective.
- Maltego: Helps map out the digital footprint of a target organization.
- Shodan: A search engine that scans for IoT devices, making it possible to discover exposed hardware.
Subdomain Enumeration: Tools like Sublist3r or Amass can help discover subdomains that might be less secure.
- Sublist3r: Gathers subdomains using multiple search engines.
- Amass: An open-source tool that focuses on in-depth DNS enumeration.
Active Reconnaissance
Port Scanning: Use tools like Nmap or Masscan to identify open ports and services.
- Nmap: A versatile network scanning tool that can identify services running on a host.
- Masscan: Known for its speed, it can scan the entire internet within hours.
Server Fingerprinting: Use WhatWeb and Wappalyzer to identify technologies and software versions running on the server.
- WhatWeb: Recognizes web technologies and versions used on a website.
- Wappalyzer: A browser extension that identifies software used on websites.
Phase 2: Scanning and Enumeration
Vulnerability Scanning
Automated Vulnerability Scanners: Tools like OpenVAS, Nessus, and Nexpose help identify known vulnerabilities quickly.
- OpenVAS: An open-source vulnerability scanner useful for initial scans.
- Nessus: A comprehensive vulnerability scanner popular among professionals.
- Nexpose: Known for providing actionable insights and reporting.
Manual Vulnerability Assessment
Exploitation Frameworks: Metasploit and Burp Suite can be invaluable here.
- Metasploit: This penetration testing framework helps exploit known vulnerabilities.
- Burp Suite: An all-in-one web vulnerability scanner and manual testing tool.
Phase 3: Gaining Access
Exploiting Vulnerabilities
Injection Attacks: SQL Injection (SQLi) and Command Injection are common vulnerabilities.
- SQL Injection: Use tools like SQLmap to automate the exploitation process.
- Command Injection: Manually exploit to run arbitrary commands on the host OS.
Cross-Site Scripting (XSS): Leverage tools like XSSer to automate XSS attacks.
- XSSer: Finds and exploits XSS bugs.
Credential Attacks
Brute Force Attacks: Hydra and Crunch can automate brute-forcing login credentials.
- Hydra: A fast and flexible login cracker.
- Crunch: A wordlist generator, useful for creating custom password lists.
Phishing: Use tools like SET (Social-Engineer Toolkit) for creating convincing phishing campaigns.
- SET: Primarily focuses on social engineering attacks.
Phase 4: Escalating Privileges
Local Privilege Escalation
Kernel Exploits: Tools like Linux Exploit Suggester help identify potential exploits.
- Linux Exploit Suggester: Recommends exploits based on the kernel version.
Automated Exploitation: John the Ripper can brute-force password hashes.
- John the Ripper: A fast password cracker useful for Linux and Windows.
Network Pivoting
- ProxyChains: Routes TCP connections through multiple proxies for anonymity.
- SSH Tunneling: Using SSH to route traffic enables access to internal networks.
Phase 5: Maintaining Access
Installing Backdoors: Custom backdoor shells can maintain persistence.
- PHP Web Shells: Tools like Weevely allow command execution.
- SSH Keys: Adding SSH keys to authorized_keys for persistent access.
Hacking Tutorials: Advanced Scenarios
Advanced XSS Attacks
Session Hijacking: Use stolen cookies to impersonate users.
- Example:
<script>document.cookie="cookie_name=cookie_value";</script>
DOM-based XSS: Modify the DOM of a victim’s browser to exploit without touching server code.
- Example:
<script>var e = document.createElement('img'); e.src='<URL>'; document.body.appendChild(e);</script>
Bypassing 2FA
Social Engineering: Contact users to glean information.
- Spoofed Emails: Use SET to send emails from seemingly legitimate sources.
Man-in-the-Middle (MitM): Use tools like Bettercap to intercept 2FA tokens.
- Bettercap: A powerful MitM framework.
Phase 6: Exfiltration
Data Exfiltration Techniques
Custom Malware: Develop malware tailored for data exfiltration.
- Example: Python scripts that compress and encrypt data before sending.
Encrypted Channels: Use tools like OpenVPN or SSH Tunnel.
- OpenVPN: Ensures encrypted communications during data transfers.
