Mikko Hyppönen, director of antivirus research at F-Secure, said he believes the source code is genuine but, worryingly, he said, it is written in pure assembler, which indicates the author responsible is a serious programmer and not a script kiddie.

"Most e-mail worms are written in C or partly in C and partly in assembler. There are not that many people that are this good in assembler any more, so it is a serious programmer behind it," said Hyppönen.

Interesting aspect of this story - written in assembly.
