Hacker Brandon Wilson decided to tinker with Activision's Skylanders action figures to see how they work. In case you don't know, Skylanders uses action figures that are placed on a portal peripheral that makes them appear in the game by reading the bottom of the figure.
After playing around with the action figure's RFID bases, he collected data and stored it in a .zip file on his personal website. He didn't think much of it at the time, but he would soon find out that some people didn't like him or his data very much. One day Wilson came home from work to find someone waiting for him at his door. It was a process server who handed him a legal notice (a cease-and-desist letter, to be precise) from Activision, accusing him of hacking and demanding that he take down all that work he stored on his website..
Wilson says that the most of the accusations from Activision are completely inaccurate. For instance, they allege that he reverse-engineered the Skylanders RFID code, is working with others to hack the game, and is collaborating those efforts on a message board.
Activision claims in its legal notice that Wilson's hacking efforts would enable changing the stats and equipment of the Skylanders without actually playing the game. They also say that the hacking could enable players to use something other than a Skylanders model to allow a user to switch back and forth between Skylanders they didn’t own.
Wilson points out in his response to Activision that none of the examples pointed out in the take down notice, including a link to a website where Wilson supposedly published his findings, are true. Wilson says that the only thing he had was a zip file with the file dump from one of the Skylanders, which wasn’t made public and wasn’t announced when it was put on his website. Despite all of that, Wilson removed the information from his website, and replaced them with the take down notice and his response.
