First Prank:
I have a friend who really likes to read people.com, so I figured I would "enrich" her life a bit with another source of daily news :)
I decided to play around with her hosts file, so that when she visited people.com, she really got the New York Times (the realest news I could think of at that time, though there are plenty of fine candidates).
To quote the Wikipedia article on hosts files:
"The hosts file...assists in addressing network nodes in a computer network. It is a common part of an operating system's Internet Protocol (IP) implementation, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, that identify and locate a host in an IP network."More importantly: "the /etc/hosts file...allows you to add entries that traditionally your computer will look up first before trying your server DNS." (source) This means that even though the DNS Lookup provided by her ISP could resolve people.com, her browser would get an IP address from the hosts file first and hence will render the New York Times page for people.com.
The first step to do this was to find the IP address for the replacement site:
$ ping www.nytimes.com PING www.nytimes.com (199.239.136.200): 56 data bytes 64 bytes from 199.239.136.200: icmp_seq=0 ttl=64 time=0.062 ms 64 bytes from 199.239.136.200: icmp_seq=1 ttl=64 time=0.054 ms ...For the second (and final) step, I just needed to add an entry to the hosts file. After locating the file on her Macbook in /etc/hosts, I updated the contents:
## # Host Database # # localhost is used to configure the loopback interface # when the system is booting. Do not change this entry. ## 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost 199.239.136.200 people.com # New entryVoilà! With that, the prank was complete and the next time she visited people.com, the got the contents of nytimes.com in her browser.
Second Prank coming soon.
