Introduction

Bug bounty programs have emerged as a critical component of cybersecurity strategies, enabling organizations to leverage global hacker talent to identify vulnerabilities that automated tools often miss. These programs offer a cost-effective and scalable way to enhance security posture while fostering collaboration between ethical hackers and enterprises.

Learning Objectives

  • Understand the role of bug bounty programs in vulnerability discovery.
  • Learn key commands and techniques used by ethical hackers in bug bounty hunting.
  • Explore best practices for securing systems against common exploits.

You Should Know

1. Reconnaissance with Subdomain Enumeration

Command:

subfinder -d example.com -o subdomains.txt

Step-by-Step Guide:

Subdomain enumeration is a critical first step in bug bounty hunting. The `subfinder` tool scans a target domain (e.g., example.com) and outputs discovered subdomains to a file.

1. Install `subfinder`:

go install -v github.com/projectdiscovery/subfinder/v2/cmd/subfinder@latest

2. Run the scan:

subfinder -d example.com -o subdomains.txt

3. Review the results for hidden or misconfigured subdomains that may expose vulnerabilities.

2. Exploiting SQL Injection Vulnerabilities

Command:

sqlmap -u "https://example.com/login?id=1" --dbs

Step-by-Step Guide:

SQL injection remains a top web application vulnerability. `sqlmap` automates the detection and exploitation of SQLi flaws.

1. Install `sqlmap`:

pip install sqlmap

2. Test a vulnerable parameter:

sqlmap -u "https://example.com/login?id=1" --dbs

3. Use `–dbs` to list databases, then `-D –tables` to extract tables.

3. Hardening API Security with JWT Validation

Code Snippet (Node.js):

const jwt = require('jsonwebtoken'); 
const token = jwt.verify(req.headers.authorization, 'secret_key');

Step-by-Step Guide:

APIs often use JWTs for authentication. Validate tokens to prevent unauthorized access:

1. Install the `jsonwebtoken` package:

npm install jsonwebtoken

2. Verify incoming tokens in middleware:

const decoded = jwt.verify(token, 'secret_key');

3. Reject invalid or expired tokens to block exploitation attempts.

4. Cloud Hardening: Restricting S3 Bucket Permissions

AWS CLI Command:

aws s3api put-bucket-policy --bucket my-bucket --policy file://policy.json

Step-by-Step Guide:

Misconfigured S3 buckets are a common attack vector. Apply least-privilege policies:

1. Create a `policy.json` file:

{
"Version": "2012-10-17",
"Statement": [{ 
"Effect": "Deny", 
"Principal": "", 
"Action": "s3:GetObject", 
"Resource": "arn:aws:s3:::my-bucket/", 
"Condition": {"NotIpAddress": {"aws:SourceIp": ["192.0.2.0/24"]}} 
}] 
}

2. Apply the policy:

aws s3api put-bucket-policy --bucket my-bucket --policy file://policy.json

5. Detecting Vulnerabilities with Nmap

Command:

nmap -sV --script vulners -p 80,443 example.com

Step-by-Step Guide:

Nmap’s `vulners` script identifies known vulnerabilities in services:

1. Install Nmap and the `vulners` script:

sudo apt install nmap && sudo nmap --script-updatedb

2. Scan for vulnerabilities:

nmap -sV --script vulners -p 80,443 example.com

3. Review CVE listings and patch affected services.

What Undercode Say

  • Key Takeaway 1: Bug bounty programs democratize security testing by crowdsourcing expertise, reducing reliance on expensive audits.
  • Key Takeaway 2: Automation tools like `sqlmap` and `subfinder` are essential, but human creativity uncovers logic flaws automation misses.

Analysis:

The future of cybersecurity lies in hybrid approaches—combining automated scans with human-led penetration testing. As AI-powered red-teaming evolves, bug bounty platforms will integrate machine learning to prioritize findings and reduce false positives. However, ethical hacking will remain a human-driven field, requiring continuous training and adaptability. Organizations must invest in both technology and talent to stay ahead of threats.

Prediction

By 2025, 60% of enterprises will adopt bug bounty programs as a standard practice, driven by rising cyber insurance requirements and regulatory pressures. AI will augment but not replace human hunters, focusing on pattern recognition and triage.
