Another comment about the content of this article:
Three quarters down the wiki page there is code for "adding foreign language" to the code. The options are are to add code comments in Arabic/Chinese/Russian/Korean/Farsi. My gut reaction is the purpose of this added language is to obfuscate the true source of the code - i.e. the code has Chinese comments in it so it must be from China. Ahh. I guess this makes sense to do. Only problem now is that the Chinese/Russian/Farsi/etc characters that they included in their code is now public. (Obviously now the CIA will change the foreign language words they insert)
I'd posit if someone had an X-year-old (i.e. x=7) copy of some malware, and the malware had these specific foreign language comments as shown by the article, there's a good possibility the source of the malware would be from the us government.
