Several of the early MIT hacks tended to be sensible jokes. One particular of the most extravagant saw a replica of a campus police automobile put on prime of the Institute’s Terrific Dome.

Why Does a Hacker Hack?
Hackers’ motivations vary. For some, it’s economic. They earn a living through cybercrime. Some have a political or social agenda – their aim is to vandalize high-profile computer systems to make a statement.

1. SideJacking / Sniffing

This is the easiest and most basic kind of wireless attack.
