I just woke up and saw this article that caught my attention (yes, i have a problem, the first thing i read in the morning is not the newspaper but securityfocus.com)

I haven't read it yet, but i'm a sucker for articles/papers with hex numbers and assembler source code :).
I'll read it later today and make a post if i can think of sthg worth saying about it :).
