Have you ever wondered what happens when a trusted website links to an expired domain? It creates a massive security blind spot. Welcome back to another video on CyberSecurityTV! Today, we are exploring the critical vulnerability known as Second-Order Domain Takeover. We will uncover how deprecated and unmonitored root domains can become an absolute nightmare for organizations, leading to phishing, malware distribution, and even supply chain attacks. In this video, we break down: ✔️ What a Second-Order Domain Takeover actually is. ✔️ How it differs from a standard Subdomain Takeover. ✔️ Where to hunt for these expired domains (DNS Records, JavaScript, API responses). ✔️ How to exploit the issue by claiming dead domains via bulk WHOIS lookups. ✔️ Why organizations often ignore this risk and how to prove its critical impact. ✔️ A real-world supply chain attack scenario involving a WordPress plugin. ✔️ Mitigation strategies and continuous monitoring techniques. This walkthrough is perfect for bug bounty hunters, penetration testers, and security teams looking to secure their external attack surface.
