It turns out, it’s just some object oriented C:
Kaspersky Lab experts now say with a high degree of certainty that the Duqu framework was written using a custom object-oriented extension to C, generally called “OO C” and compiled with Microsoft Visual Studio Compiler 2008 (MSVC 2008) with special options for optimizing code size and inline expansion.

If you missed it in the news, you should definitely read this: The Mystery of the Duqu Framework.
Here, security companies first discovered a virus (yet an other one) and then discovered it was embedding it’s own framework (and we can pretty much guess there’s a dedicated language for that one). This story uncovers a real mistery with its set of questions: why did some people decided to create a new framework? Why was it only used (or seen) in a virus? How could it be especially applicable to a virus? Why did they decided to use everything internally and not use standard C/C++ compilers?
The conclusions of this article are:
- The Duqu Framework appears to have been written in an unknown programming language.
- Unlike the rest of the Duqu body, it’s not C++ and it’s not compiled with Microsoft’s Visual C++ 2008.
- The highly event driven architecture points to code which was designed to be used in pretty much any kind of conditions, including asynchronous commutations.
- Given the size of the Duqu project, it is possible that another team was responsible for the framework than the team which created the drivers and wrote the system infection and exploits.
- The mysterious programming language is definitively NOT C++, Objective C, Java, Python, Ada, Lua and many other languages we have checked.
- Compared to Stuxnet (entirely written in MSVC++), this is one of the defining particularities of the Duqu framework.
Who could have done this framework? Well…
– Stuxnet, the last virus that mostly attacked Iran, was at least backed (maybe created) by the USA
– This one required the workforce of a pretty big organization (a lot of smart people put together to do evil things)
I hope we’ll discover who is behind this this someday.
