Metamorphic malware in the last years

Hello everyone,

 

I am really interested and fascinated about metamorphic malware. I read books and papers, my favourite ones were from Peter Szor, but what I couldn't find was up 2 date information about metamorphic malware. As I read in Szor's books, the last metamorphic malware, which has to be mentioned, was the Win32.Simile virus, which was released in 2000.

 

I tried to find current information on the symantec website, but I couldn't find any information. Does anybody of you know where to find updated information or at least newer information than from Peter Szor (I think his latest book is from 2005)? If anybody of you have additional material about metamorphic malware, this is welcome as well.

 

Thank you very much for your help,
