Web hacking and bug bounty hunting involve identifying vulnerabilities in web applications to enhance their security.
This field combines reconnaissance, vulnerability exploitation, and secure coding practices. Below is a detailed overview of tools and techniques commonly used in web hacking.
Reconnaissance And OSINT Techniques
Reconnaissance is the first step in ethical hacking, where information about the target system is gathered. It can be active (direct interaction with the system) or passive (indirect data collection). Key techniques include:
- Subdomain Enumeration: Tools like Sublist3r and Amass identify subdomains for potential entry points.
- Port Scanning: Nmap scans for open ports and services.
- DNS Enumeration: Identifies DNS records to uncover infrastructure details.
Bug bounty hunters focus on exploiting vulnerabilities such as:
- SQL Injection (SQLi): Exploiting databases using tools like SQLMap.
- Cross-Site Scripting (XSS): Injecting malicious scripts into web pages.
- Server-Side Request Forgery (SSRF): Manipulating server requests to access restricted resources.
- Insecure Direct Object References (IDOR): Accessing unauthorized resources by manipulating object identifiers.
Bypass methods are used to overcome security mechanisms:
- 403/429 Bypass: Circumventing access denial or rate limits.
- Captcha Bypass: Using automation tools to bypass verification.
- WAF Detection/Bypass: Evading Web Application Firewalls with tools like Burp Suite.
Top Tools For Web Hacking
- Burp Suite: Comprehensive tool for scanning, intercepting, and exploiting vulnerabilities.
- OWASP ZAP: Open-source tool for passive scanning and fuzzing.
- SQLMap: Automated SQL injection exploitation tool.
- ParamSpider: Extracts hidden parameters from URLs for further testing.
Cloud platforms like AWS, Azure, and Kubernetes introduce unique attack surfaces. Tools such as Docker security scanners help detect container vulnerabilitie.
Golden Tips For Bug Bounty Hunting
- Always review the source code for hidden vulnerabilities.
- Use Google Dorks for advanced search queries.
- Think creatively to uncover overlooked issues.
With continuous learning and practice, these tools and techniques can help ethical hackers secure web applications effectively while earning rewards through bug bounty programs.
