I was testing a website for hours… clicking, scanning, trying random payloads. I felt like I was doing "real hacking." 💻🔥 Then I gave up. Two days later… someone else reported a simple bug on the same target. Reward? $500. My mistake? 👉 I had no process. No checklist. Just random testing. That moment hurt… but it taught me something powerful: ⚠️ Bug bounty is not about being smart — it's about being systematic. And today, I'm sharing the complete bug bounty checklist that changed everything for me. 🧠 1. Reconnaissance — Where Real Hackers Win Most beginners jump straight into testing. Big mistake. ❌ Recon is where 70% of bugs are found. Here's what I do now: Collect subdomains 🌐 Find hidden endpoints Check old URLs (wayback data) Look for parameters 💡 Tools help… but mindset matters more. 👉 Think like this: "Where would a developer forget something?" 🔍 2. Understand the Target Like a User Before hacking… use the app like a normal person. Create account Login / Logout Explore every feature Why? Because most bugs hide in logic , not code. ⚠️ If you don't understand the app, you're just guessing. 🧪 3. Input Testing — The Goldmine This is where things get interesting 🔥 Test every input: Forms Search bars URL parameters Try: Special characters Scripts Unexpected data 💻 This is where vulnerabilities like XSS live. 👉 Never trust input. That's rule #1 in security. 🔐 4. Authentication & Authorization Checks This is where BIG money bugs exist 💰 Ask yourself: Can I access another user's data? Can I bypass login? Can I change roles? 🚨 Broken access control = critical vulnerability Many companies fail here. 📂 5. File Upload & Download Testing Simple… but deadly. Check: Can you upload malicious files? Can you access restricted files? Is file type validation weak? 💡 Many real-world breaches start from file upload bugs. 🌐 6. API Testing (Hidden Treasure) Modern apps run on APIs. Most hackers ignore them. That's your advantage 😉 Check: Hidden endpoints Unauthenticated requests Data leaks 🔥 APIs are full of logic flaws. ⚡ 7. Automation + Manual = Perfect Combo Tools are powerful… but not enough. Use tools for: Scanning Recon Fuzzing But… 👉 Real bugs come from manual thinking. 💡 Combine both = best results. 🧨 8. Think Like an Attacker, Not a Tester Stop following tutorials blindly. Start asking: "What can I break?" "What was the developer thinking?" This mindset shift is everything. 🚨 Hackers don't follow rules. They find gaps. 🔍 Real-World Insight (My Bug Bounty Moment) Once, I found a bug where: A user ID in the URL could be changed No proper authorization check That's it. I accessed another user's data. 💰 Reward? Not huge… but the lesson was priceless. 👉 Simple checklist + curiosity = vulnerability. 🛡️ What You Can Learn From This If you're serious about bug bounty, follow this: ✅ Always start with recon ✅ Understand the app before testing ✅ Test every input (don't skip anything) ✅ Focus on auth bugs (high impact) ✅ Explore APIs deeply ✅ Don't rely only on tools ✅ Stay consistent (daily practice) 💡 Bug bounty is a skill — not luck. 🔚 Conclusion: The Truth About Bug Hunting Most people fail in bug bounty because they: Jump randomly Don't follow a process Quit too early But the ones who win? They follow a system. They stay patient. They think differently. 🔥 And that's exactly what this checklist gives you. 💭 Final Thought What if your next vulnerability… is hiding in the one step you always skip? 🚀 #bug-bounty #cybersecurity #bug-bounty-tips #bug-bounty-writeup #info-sec-writeups Reporting a Problem Sometimes we have problems displaying some Medium posts.
