Hijacking tons of Instapage expired users Domains & Subdomains

Hello all ūüôā

so this post is about how I¬†was able to hijack ton’s of domains/subdomains who using Instapage if¬†there service got expired.

What is instapage ?

Instapage is a service that lets you build landing pages for your online marketing and promotion campaigns with ease. It offers features such as A/B Testing, multiple campaign management, easy page building, and a lot more!

it also allows users to map its template on there own domain or subdomains.

How i found it ?

as am one of researchers from HackerOne platform , I was trying to get something on HackerOne itself as I want that Hacking Hackers Badge of my profile.

I found is inscope domain list which is one of the officail website of HackerOne, and when I vistied it and seen some error which caught in my eye and after figuring it, I come to know it was Instapage error which occurs when service get expired or domain or subdoamin not linked properly and it takes just few mintues to figurte it out that I can publish my own template to any of misconfigured and expired domains/subdomains of instapage and luckly HackerOne is one of there users.

Instapage error on Hacker.One :
