Can someone show me a Cross-site scripting attack in effect on my browser? Is there an example on the internet that does this? I haven't found this on the internet.
The simpler the example is the better.
Examples of reflected cross-site scripting attacks include when an attacker stores malicious script in the data sent from a website's search or contact form. A typical example of reflected cross-site scripting is a search form, where visitors sends their search query to the server, and only they see the result.
Attackers often initiate an XSS attack by sending a malicious link to a user and enticing the user to click it. If the app or website lacks proper data sanitization, the malicious link executes the attacker's chosen code on the user's system. As a result, the attacker can steal the user's active session cookie.
Cross-site scripting (XSS) is a type of injection attack in which a threat actor inserts data, such as a malicious script, into content from trusted websites. The malicious code is then included with dynamic content delivered to a victim's browser. XSS is one of the most common cyber attack types.
