So, Who Wrote Sobig?

An anonymous reader writes "F-Secure's Virus Blog posted links to a 48-page technical study on who wrote the infamous Sobig worm which went around the world last year. The study is done by anonymous authors. The study concludes that author of this worm is a Russian programmer and goes out all the way to name him. This file has now been posted publicly but on Geocities and and Tripod. So you can have a look by yourself and make your own conclusions."
