One of the challenges in malware research is separating the truly novel innovations in malcoding from new nasties that merely include nominal or superficial tweaks. This dynamic holds true for both malware researchers and purveyors, albeit for different reasons. Researchers wish to avoid being labeled alarmist in calling special attention to what appears to be an emerging threat that turns out to be old news; the bad guys just want to avoid getting scammed into paying for an old malware kit dressed up as the new next big thing.
