The Complete Ethical Hacking Bootcamp: Beginner To Advanced - Reflected Cross-Site Scripting (XSS)

The video tutorial explains cross-site scripting (XSS) attacks, a common web application vulnerability. It covers how XSS exploits user input to execute malicious scripts, often using JavaScript, and differentiates between stored and reflected XSS. The tutorial provides examples of XSS attacks, such as redirection, and demonstrates a reflected XSS attack, highlighting the risks and potential impacts on web security.

What is considered one of the most common vulnerabilities in web applications alongside SQL injection?

• Denial of Service

• Phishing

• Buffer Overflow

• Cross-Site Scripting (XSS)

Which scripting language is most commonly used to make websites dynamic?

• Python

• JavaScript

• Ruby

• PHP

What happens when user input is not properly filtered in a web application?

• The website becomes faster

• Cross-Site Scripting vulnerabilities can occur

• The website becomes unresponsive

• The website's design changes

What is a key characteristic of a stored XSS attack?

• The attack is temporary

• The attack is easily detectable

• The malicious code is stored on the server

• The attack only affects the attacker

In a reflected XSS attack, where is the malicious script typically sent?

• To the network firewall

• To the database

• To the victim's browser

• To the server

What is the primary goal of a stored XSS attack?

• To redirect users to a different website

• To steal server resources

• To infect every visitor of the website

• To slow down the server

What is a common method used by attackers to disguise malicious links in XSS attacks?

• Shortening or changing the link

• Using HTTPS

• Using a VPN

• Encrypting the link

How can a reflected XSS attack be initiated?

• By altering the website's CSS

• By modifying the server's code

• By embedding a script in a URL

• By sending a script to the server

What can a malicious script in an XSS attack potentially do?

• Increase website traffic

• Steal cookies and hijack sessions

• Change the website's layout

• Improve website security

What is a potential consequence of clicking on a malicious link in a reflected XSS attack?

• The website's content will change

• The website will crash

• The user's browser will execute the script

• The user's internet speed will decrease
