In this case, the attack depended upon the fact that the victim was already logged into the shopping website. The attacker knew that some portion of the visitors to the message board would be logged into that site and took advantage of that trust relationship to send commands through the user’s browser to the shopping site. That’s an example of a cross-site request forgery attack. Cross-site scripting attacks work in a similar manner but they do not leverage those trust relationships. Server-side request forgery attacks target the web server itself rather than the end user. Phishing attacks attempt to trick the user into sharing sensitive information, but this attack took place without the victim’s knowledge.
