  Introduction When you log into a website and stay logged in without entering your password again, it is not magic—it is handled by cookies and sessions. Understanding how cookies and sessions work is essential for learning web security, ethical hacking, and penetration testing. This guide explains these concepts in a simple and practical way. What are Cookies Cookies are small pieces of data stored in your browser by a website. They are used to remember user information such as login status, preferences, and tracking data. Key Features of Cookies Stored on the client (browser) Sent with every HTTP request Can store session identifiers Used for tracking and authentication What are Sessions Sessions are server-side storage mechanisms that keep track of a user’s activity. Instead of storing sensitive data in the browser, sessions store it securely on the server. Key Features of Sessions Stored on the server Identified by session ID More secure than cookies Used for authentication ma...

Subdomain Takeover Guide 2026: Finding and Securing Dangling DNS Records

  Introduction In modern web infrastructures, organizations often use multiple third-party services like hosting platforms, CDNs, and SaaS tools. If these services are not configured properly, they can lead to a serious vulnerability known as Subdomain Takeover. This Subdomain Takeover guide 2026 explains how attackers identify misconfigured DNS records and how security professionals can prevent them. What is Subdomain Takeover Subdomain Takeover occurs when a subdomain points to an external service that is no longer active, but the DNS record still exists. An attacker can claim that external resource and gain control over the subdomain. Why It is Dangerous Full control over subdomain content Phishing attacks Cookie stealing Brand reputation damage How Subdomain Takeover Works A subdomain (e.g., test.example.com) points to a service (e.g., GitHub Pages) The service is deleted or inactive DNS record still exists Attacker registers the same service Attacker gains control of the subd...
