Hi, how are you? i hope you are doing great, this is my first bug bounty from bug bounty platform on

My bug bounty was bypassing OTP Verification SMS, but before we started i will explain what is and OTP

Bug Bounty Platform

What is OTP?

A one-time password (OTP), also known as one-time PIN or dynamic password, is a password that is valid for only one login session or transaction, on a computer system or other digital device.

At that day i was reading around on, and i noticed Indodax Bug Bounty Program, so i tried to find some bugs on there, at the first i’m trying to find a host header injection but i got no luck at all.

Don’t Give Up!

I try to register a new account, and i was asked to enter the phone number when registering the account, so i input a random phone number and finished register account.

After that i verify my email and i asked to verify my phone number, then crossed my mind to bypass the sms verification, so i fired up my Burpsuite - capture the request send it to repeater and here’s what i got


Then i try to input 6 random number and BOOM! here’s the response from my Burp


{“success”:”Terima kasih, verifikasi telah berhasil!”}
