Bug Bounty Tutorial Exclusive ((link)) -
Kael’s heart sank. Then he remembered Echo’s final rule, buried at the bottom of readme.txt :
What is your current with proxy tools like Burp Suite?
Use dnsgen to generate variations of discovered subdomains (e.g., changing ://target.com to ://target.com ), then resolve them using a fast DNS client like puredns . 2. Port Scanning and Service Discovery
The dirty secret of the industry is that most public tutorials teach you how to use tools , but not how to think . Exclusive bug hunting isn't about running a vulnerability scanner; it's about , edge-case exploitation , and advanced recon . bug bounty tutorial exclusive
He used curl -X OPTIONS https://cdn-staging.nexuscore.com/api/v2/debug . The response header bled secrets:
Check for CSRF in GET requests that modify data. Those are often overlooked and can be triggered with <img src="https://target.com/delete?user=123"> .
This guide is not about running a scanner and copying-pasting results. It is about the methodology, the mindset, and the minute details that separate the top 1% of hunters from the noise. Kael’s heart sank
Clear and impactful (e.g., "Account Takeover via Password Reset Logic Flaw"). Severity: Be honest; don't over-inflate. Description: What is the bug?
Excellent guidance on navigating private invite-only programs.
You found a critical bug. You write: "XSS on index.php." You get $0. He used curl -X OPTIONS https://cdn-staging
When hacking an application, read its user manual or API documentation. Understanding how a feature is designed to work helps you figure out how to break its logic.
: Many WAFs fail to parse complex or non-standard JSON formatting. Try introducing massive whitespace blocks, unicode-escaped characters ( \u0027 instead of ' ), or duplicate keys within JSON payloads to confuse the firewall's parser. Request Smuggling (CL.TE / TE.CL)
When you find a vulnerability, ask: "What can this touch?"
: When an application performs a multi-step process (e.g., validating a gift card, then adding balance, then marking the card as used), flood the server with simultaneous requests using HTTP/2 multiplexing. You can often trigger the balance addition multiple times before the card is marked as used. Second-Order Vulnerabilities
Do not just rely on standard subdomain wordlists. Top hunters use permutation tools to generate targeted lists based on a company’s naming conventions.
