The complexity of the code within this threat is at par with that seen in Stuxnet and Duqu, arguably the two most complex pieces of malware we have analyzed to date. As with the previous two threats, this code was not likely to have been written by a single individual but by an organized, well-funded group of people working to a clear set of directives. Certain file names associated with the threat are identical to those described in an incident involving the Iranian Oil Ministry.
