Perhaps because this is no simple virus? Perhaps because Stuxnet/Duqu is one of if not the most sophisticated examples of cyber warfare* we have public examples of? Perhaps because its compiled binary is a whopping half-megabyte in size?
The amount of effort that went into Stuxnet is truly massive. It'd be no surprise if a custom framework or even a domain-specific language were written to support it.
* Usually I cringe at just hearing the phrase cyber warfare and at the ridiculous way in which it is used by media and the government. But looking at what Stuxnet accomplished (physically damaging or disabling critical components of the Iranian nuclear enrichment program), the term applies completely.
