Exploiting Reflected XSS to steal login credentials
Another very common type of XSS attack is a phishing attack. Phishing attacks usually utilize legitimate-looking information to trick the victims into sending their sensitive information to the attacker. A common form of XSS phishing attacks is through injecting fake login forms that send the login details to the attacker’s server, which may then be used to log in on behalf of the victim and gain control over their account and sensitive information.
Furthermore, suppose we were to identify an XSS vulnerability in a web application for a particular organization. In that case, we can use such an attack as a phishing simulation exercise, which will also help us evaluate the security awareness of the organization’s employees, especially if they trust the vulnerable web application and do not expect it to harm them.
This is the question solved in the video –
Try to find a working XSS payload for the Image URL form found at ‘/phishing’ in the above server, and then use what you learned in this section to prepare a malicious URL that injects a malicious login form. Then visit ‘/phishing/send.php’ to send the URL to the victim, and they will log into the malicious login form. If you did everything correctly, you should receive the victim’s login credentials, which you can use to log in to ‘/phishing/login.php’ and obtain the flag.
