InformationWeek: Security researchers from Kapersky Lab say that the Stuxnet and Duqu viruses shared a common platform that could date back to 2007. The “Tilded” platform could also have been used to create other malware as well. “There were a number of projects involving programs based on the ‘Tilded’ platform throughout the period 2007-2011,” said Kaspersky’s Alexander Gostav. “Stuxnet and Duqu are two of them–there could have been others, which for now remain unknown.”
Gostav warned that the Tilded platform is likely still under development and could also spawn new malware in the future.
