Well, in TFA it mentions it's the first time that anyone in Japan has been charged with "property destruction" for creating a virus. Also, he created all the images himself so he wouldn't get arrested for copyright infringement. Of course, none of this is made clear in the summary, and I think the latter point is more him being a smartass. I thought maybe he was a mis-aimed White Hat, but no, he was collecting the data from the affected computers as well and just hanging onto it. So, I guess that falls under YRO as a general "computer law" issue, but it's kind of an unnecessary story since it's just a guy getting arrested for making a virus. How original!
