Bug bounty hunting is a critical skill in the cybersecurity domain, where ethical hackers identify vulnerabilities in systems and report them to organizations for rewards. This article provides a detailed guide to bug bounty hunting, complete with practical commands and tools to get started.

Essential Tools for Bug Bounty Hunting

  1. Nmap: A network scanning tool used to discover hosts and services on a computer network.

Command: `nmap -sV -p 1-65535 target.com`

This command scans all ports on the target domain and detects service versions.

  1. Burp Suite: A web vulnerability scanner used for testing web application security.
    Command: Use Burp Suite’s proxy tool to intercept and modify HTTP requests.

  2. Nikto: A web server scanner that tests for dangerous files, outdated server software, and other vulnerabilities.

Command: `nikto -h target.com`

  1. SQLmap: A tool for detecting and exploiting SQL injection flaws.
    Command: `sqlmap -u “http://target.com/page?id=1” –dbs`

  2. Metasploit: A penetration testing framework that helps in exploiting vulnerabilities.
    Command: `msfconsole` to launch the framework, followed by `use exploit/windows/smb/ms17_010_eternalblue` for exploiting specific vulnerabilities.

Practical Commands for Reconnaissance

  • Subdomain Enumeration: Use tools like `Sublist3r` to find subdomains.

Command: `sublist3r -d target.com`

  • Directory Brute-Forcing: Use `Dirb` or `Gobuster` to find hidden directories.
    Command: `gobuster dir -u http://target.com -w /path/to/wordlist.txt`

  • SSL/TLS Testing: Use `SSLScan` to check for weak SSL/TLS configurations.

Command: `sslscan target.com`

What Undercode Say

Bug bounty hunting is a dynamic and rewarding field that requires continuous learning and practice. By mastering tools like Nmap, Burp Suite, and Metasploit, you can identify vulnerabilities and secure systems effectively. Always ensure you have proper authorization before testing any system. For further learning, explore platforms like HackerOne and Bugcrowd.

Linux commands like netstat, tcpdump, and `iptables` are invaluable for network analysis and security. On Windows, tools like `Powershell` and `Sysinternals` provide deep insights into system vulnerabilities. Remember, the key to success in bug bounty hunting is persistence, curiosity, and a strong ethical foundation.
