Business Logic Flaws Uncovered: A Bug Hunter’s Series Launch
How I Started Hunting Flaws That Aren’t Bugs — They’re Broken Rules
Hello — I’m Yamini Yadav. I’m a security engineer, OSCP-certified penetration tester, and a bug bounty hunter. Over the years, I have found many vulnerabilities that were not memory bugs or SQL injections. They were simpler and more interesting: the application behaved correctly, but the business logic was wrong. The result: users could do things they should not, money could be stolen, orders could be cancelled, and privacy could be destroyed — all through ordinary-looking workflows.
This series is for security engineers, pentesters, bug hunters, QA engineers, and developers who want to think like an attacker and fix the flaws before the attackers find them. Welcome to “Business Logic Flaws Uncovered: A Bug Hunter’s Guide.”
In this first post, I’ll:
- Tell a real hunting story that explains why business logic bugs are exciting and dangerous.
- Explain what business logic flaws are, with clear examples.
- Share the tools and hunting mindset I use.
- Walk through a compact testing methodology you can use now.
- Map the series and describe the upcoming deep-dive…
