Korgo Worm Threat Grows: Page 2 of 2

Korgo also employs mutex (mutual exclusion objects), which can control access to system resources and even prevent system resources from being used simultaneously during a compute process.

"We have not been able to determine the goal of this worm's creator," said Luis Corrons, head of PandaLabs, in a statement. "The amount of work being put into the development of the Korgo variants would suggest that this is more than just someone having a bit of fun. This is also far from the typical virus strategy of simply getting as many variants in circulation as quickly as possible to infect as many computers as possible, as they have taken the trouble to make their creations delete their own predecessors."
