Kaspersky hopes to identify Duqu Trojan written in unknown programming language. Language could help analysts build a profile of DuQu’s authors. Duqu first emerged in September 2011 and is thought to have been written by the same people behind the infamous Stuxnet worm. Other languages ruled out include Python, Java, Objective C, Ada and Lua. The language could be the work of a separate collaborator, indicating multiple parties worked to develop the infection, security experts say. The worm was able to communicate with its Command and Control servers.
