How to build your intuition in finding web app bugs?

Disclaimer: I’m not good in this and still learning, just want to share my experience.

I’ve noticed that there are so many questions in reddit asking how to start web pentest, how to be good in it, etc.

Short answer: Read, practice, repeat the process

Long answer:

The reason why I write the post here is I find that very difficult in real life to get someone to guide, help and show me tips and tricks. Instead, I had to learn it the hard way and find the answer by myself. So, I hope that by this little sharing I can help those who are struggling just like me. Remember, you’re not alone out there, this subreddit is very helpful. I’m glad I found this.

I used to try different vulnerable web apps such as DVWA, Mutillidae, WebGoat, and many more.

What I did wrong was I did not try hard to understand what the application does. Instead, when I stuck, I was quickly google for solution, and read about the walkthrough and solution for that challenge.

When I do more practice, I realize that in order to build intuition to find a real bug, I really need to map the application, click every single links available, try to really understand every single functions available (while sending all this requests to Burp so that I can analyze it later). Believe me, this part is very important.

Let’s take a look a Lab from Web Security Academy

I know this is particularly targeted against “CSRF vulnerability with no defenses”, but when you try it, try to use different payload as you’re on a real target where you don’t know what is the actual vulnerability.

Keep doing this and I believe you’ll getting better from day to day.

Once you find the solution, look at the walk-through, see what others do differently. You might be able to learn one or two tricks from there.

This is what I’ve been doing lately, and if there are more tips and tricks, e.g. how did you learn, feel free to share it especially on web app, api, or mobile pentest.
