📚 The Smarter Bug Hunting (For Low Hanging Bug)
📌 Step 1: Gather Recon Data
The foundation of bug hunting is solid reconnaissance. Use tools like Amass and Subfinder to discover subdomains.
#amass enum -d
target.com
#subfinder -d
target.com -o subdomains.txt
💡 Tip: Target overlooked assets like staging environments or old subdomains—gold mines for misconfigurations!
📌 Step 2: Look for Open Ports
Scanning for open ports and services can lead you to hidden vulnerabilities. Use Nmap:
#nmap -sV -p- -iL subdomains.txt -oN nmap_results.txt
💡 Tip: Pay attention to non-standard ports; they often harbor interesting services.
📌 Step 3: Identify Vulnerable Endpoints
Use httpx to detect live endpoints:
#httpx -l subdomains.txt -o live_endpoints.txt
Follow up with FFUF for fuzzing:
#ffuf -u
target.com/FUZZ -w /path/to/wordlist.txt -mc 200,403
💡 Tip: Fuzz for directories like /admin, /test, and /backup.
📌 Step 4: Test for Common Bugs
Some of the easiest yet impactful vulnerabilities include
1. IDOR (Insecure Direct Object References)
2. Misconfigurations in headers or access controls
3. Default credentials in login panels
Example: Testing for IDOR with Burp Suite:
1. Intercept requests and modify object IDs or parameters.
2. Observe the response for unauthorized data.
📌 Step 5: Automate Your Findings
Tools like Hakrawler can help you crawl and identify more endpoints:
#hakrawler -url
target.com -depth 2 -plain > urls.txt
Pair it with ParamSpider for parameter discovery:
#python3 paramspider.py --domain
target.com
🔑 Key Takeaway: Focus on actionable bugs with high reproducibility. These might seem small, but in the right context, they’re incredibly impactful!
