The new found connection concerns a special module known as ‘Resource 207’ that was found in earliest known version of Stuxnet, created in 2009 but was later removed from the 2010 version. ‘Resource 207’ has a lot in common with the code used in Flame.
Resemblances include the names of mutually exclusive objects, the algorithm used to decrypt strings, and similar approaches to file naming. Furthermore, the primary function of ‘Resource 207’ was to distribute the Stuxnet infection from machine to another through removable USB drives. The code which is responsible for distribution of malware using USB drives is completely identical to the one used in Flame.
However despite the newly discovered facts, Mr Gostev remains confident that Flame and Stuxnet originate from completely different platforms, used to develop multiple cyber-weapons.
