Master the CHFI Challenge 2025: Crack the Code and Become a Cyber Sleuth!

The attack described is a Cross-Site Request Forgery (CSRF) attack. In a CSRF attack, an unauthorized command is transmitted from a user that a web application trusts. This happens when a user is tricked into clicking a link or visiting a malicious site while they are logged into a legitimate site. The malicious request can utilize the user's session cookies, which the legitimate site recognizes as valid, enabling the attacker to perform actions on behalf of the user without their consent.

Understanding how CSRF works is crucial. It exploits the trust a web application has in the user's browser rather than exploiting a vulnerability within the application itself. When the user is authenticated on a site, the browser automatically includes the session cookie with requests to that site. If the malicious site successfully induces the user to perform an action, the session cookie is sent along, resulting in potentially harmful actions being executed.

This contrasts with choices like Web Application Denial-of-Service (DoS), which focuses on overwhelming a service to make it unavailable, or Cross-Site Scripting (XSS), which involves injecting malicious scripts into a webpage that can execute actions in a user's browser. Hidden Field Manipulation deals with unauthorized changes to hidden fields in a form before submission. Each of these attacks
