What is the most likely type of attack that occurred when a user entered their credentials into a forged recruiting application website?

When a user enters their credentials on a forged recruiting application website, this scenario is indicative of an SSL strip MITM (Man-In-The-Middle) attack. In this type of attack, the attacker intercepts communication between the user and a legitimate website. The forged site may appear similar to the actual recruiting application website, tricking the user into entering their credentials.

In an SSL strip attack, the attacker creates an unencrypted version of a secure website and presents it to the victim. When the user tries to access the legitimate site, they are instead redirected to the attacker’s site. Because the connection is no longer secure (i.e., it does not use HTTPS), the attacker can easily capture the user's login information. This method exploits users' lack of awareness regarding the security features of websites, such as the presence of HTTPS and padlock icons in their browser.

This specific mechanism highlights the risk associated with entering sensitive information into sites that may not be verified for authenticity, as the user’s credentials can be exposed in transit without proper encryption and security measures.
