What I want to say about using Msn is something simple but effective for hackers. For example when an attacker want to plan for attacking a website, the first thing need want to do is to index the webserver to see if there's any vulnerable scripts/programs/mods on the machine, then he is just going to use this to put his hand on the machine then start working.
However, it's work like this: Go and get the IP of the site or machine you want to attack, then go to
http://www.msn.com. type the IP of the site/machine in the search bar and before the IP type "ip:" so it will be like this: ip:196.168.0.12 and see what I'm talking about.
Note1: Now you just indexed the webserver, but you can edit this search to get the scripts running by keywords or the programs installed in the machine even you can get the kernel version "for *nix OS".
Note2: This is helping script kiddies for sure

but it's also should be covered in the CEH. To be a Certified Ethical Hacker means you must be aware of such methods, and thats in my opinion.
