At BlackHat/Defcon 2002 SensePost released a paper on the now-famous Trojan called Setiri. While the Trojan was demonstrated (with great success) the source was never released. SensePost has since been contacted by many "anti-virus vendors" in order to obtain the source.

There was an interesting Write-up by Kim Zetter (then PCWorld, now Wired).

In his Book on Malware Ed Skoudis also dedicates an entire section on Setiri.
