When it comes to subdomain takeover hunting, there’s nothing quite like the sweet combination of manual analysis and automation. While manual techniques give you that granular control, automation simplifies and accelerates the process, making it more efficient and scalable. In this blog post, I’ll walk you through how I automate the process of finding subdomain takeovers, from start to finish. Let’s dive in!
Why Subdomain Takeover?
Before we jump into the technical details, let’s talk about why subdomain takeover is a critical issue. A subdomain takeover occurs when a subdomain points to an external service (like GitHub Pages, Heroku, etc.) that has been deleted or is no longer in use.
