You type the web address of a political website correctly in your browser but the web content you see contains political messages highly critical of the candidate that owns the website, messages the candidate would never permit on his site. You call your friend who uses a different internet service provider and she tells you that when she access the same website, she sees only the expected content, none of the critical content you see. Assuming that no malicious changes have been made to your system, which of the following is the most likely explanation for these different views of the same website?

a) The candidate's website has been defaced.

b) A DNS cache poisoning attack has been successfully perpetrated against your local name server but not that of your friend.

c) The authoritative DNS server for the website's domain has been hacked.

d) A DDOS attack against the website is underway.

e) Your session has been hijacked
