Okay so you've got a website in front of you. Someone said "go find bugs in this." And now you're just… sitting there. Staring at it.

Yeah. I've been there.

Nobody tells you this part. Every tutorial jumps straight into tools and techniques and vulnerability types. But before any of that matters, there's a thinking process you have to go through — and most beginners skip it completely. That's why they end up going in circles and finding nothing.

So forget tools for a second. Let me just walk you through how I actually think when I open a website for the first time.

Step one: just use the website like a normal person

Seriously. Before you do anything else, just use it.

Make an account. Log in. Click every button you can find. Go through whatever the website is supposed to do — if it's a shopping site, browse products and add something to your cart. If it's a social platform, make a post, follow someone, send a message. If there's a profile page, edit it. If there's a search bar, search for something.

The goal here isn't to find anything yet. The goal is to understand what this website actually does and how it works.

Think of it like this: if you were a detective investigating a building, you wouldn't just start randomly kicking down doors. You'd first walk around, look at the layout, understand what each room is for. That's what you're doing here.

While you're clicking around, notice things. Where does the website ask you to give it information? Where does it show you information? What can logged-in users do that logged-out users can't? Which features feel more complex than the others?

Just get curious. Explore it like you genuinely want to understand it.

Step two: start looking at the parts most people ignore

Once you've got a feel for the main website, start poking around the edges.

Most beginners focus all their attention on the homepage and the obvious features. That's exactly what everyone else does too. The thing is, websites are big. They have corners that developers built years ago and kind of forgot about. Old pages. Sections that aren't linked from anywhere obvious. Parts of the website that used to exist and technically still do.

Those forgotten corners? That's where the interesting stuff usually is.

So start exploring beyond what the website shows you on the surface. Try typing things into the address bar directly. If the website is example.com, what happens when you visit example.com/admin? Or example.com/old? Or example.com/test? A lot of these will give you a "page not found" — but sometimes they don't. Sometimes something shows up that really shouldn't be there.

Also look at the website from different angles. What does it look like when you're not logged in vs when you are? What happens if you log in as a regular user and try to visit pages that feel like they should be admin-only? What happens when you try things the website probably didn't expect you to do?

You're not hacking yet. You're just being nosy. That's the job.

Step three: pay attention to anything that feels off

As you're exploring, you'll start noticing things that feel a little weird. Trust that feeling.

Maybe a page loads differently than the others. Maybe you noticed the URL has a number in it — like /profile/1042 — and you wonder what happens if you change that number. Maybe a form accepts something and you're not sure what it does with it. Maybe a feature behaves differently depending on whether you're logged in or not, in a way that doesn't quite make sense.

Write these things down. Anything that makes you think "huh, that's interesting" — note it.

The mindset you want to build is: normal things work the way they're supposed to. Weird things are worth a closer look.

Step four: think about what the website is trusting you on

This is where it starts getting fun.

Every website has to make decisions about what to trust. When you click "view my order," the website trusts that you should be allowed to see that order. When you upload a profile picture, the website trusts that the file you're uploading is actually a picture. When you fill in a form, the website trusts that you're putting in the kind of input it expected.

Your job as a bug hunter is to ask: what happens when those assumptions are wrong?

What if you changed the order ID in the URL to someone else's order number — does the website check that it belongs to you, or does it just show it? What if you typed something unexpected into a form field instead of the normal input? What if you logged in as a regular user and tried to do something only an admin should be able to do?

You're not trying to break anything randomly. You're asking specific, logical questions. "The website is assuming X about me — what if X isn't true?"

Here's how this thinking actually found a real bug

I was looking at a website — a platform where businesses could create accounts and manage their stuff. The main features were clean and worked fine. Nothing obviously wrong.

But when I was exploring, I noticed something. Every time I visited my own account page, the URL had a number in it. Something like /account/details/1042. Just sitting there in the address bar.

And I thought: that number is probably how the website knows which account to show. So what happens if I change it?

I changed 1042 to 1041. Hit enter.

Someone else's account page loaded. Full details. Name, email, business information. No error. No "you're not allowed here." The website just showed it to me, because I asked for it.

That's it. No special tools. No technical wizardry. Just noticing a number in a URL, asking a logical question, and testing what happened. The website was trusting that if you knew the account number, you were supposed to see it. It wasn't actually checking if the account belonged to you.

That kind of bug — where you can access someone else's stuff just by changing an ID — is one of the most common ones out there. And it gets found all the time by people doing exactly what I just described.

The last thing: go deep on one idea at a time

After you've explored the website, you'll have a list of things that felt interesting or weird. Maybe three things, maybe ten.

Here's the mistake beginners make: they jump between all of them, spending five minutes on each, and never actually get anywhere.

Pick one. The one that felt most interesting, the one that made you most curious. Focus on that. Try it different ways. Think through the logic of why it might be a bug. Keep pulling that thread until you either find something or genuinely rule it out. Then move to the next.

Patience and focus will take you further than speed.

That's really it

I know this isn't the "here are 15 tools to install" post you might have expected. But honestly, tools come after this. If you don't have this foundation — explore the whole website, notice what's weird, think about what the website is trusting you on, go deep on one thing at a time — then tools won't help you anyway.

Get comfortable with a website first. Get curious. Ask logical questions. That's what bug hunting actually is, underneath all the technical stuff.

Most bugs aren't found by magic tools. They're found by people who notice something slightly weird and decide to ask one more question.
