Actually they have a very good understanding of what happened in this case.
It's nothing spectacular.
In the past some serious leaks and attacks happened with pretty much nobody paying attention.
This here is a publicity stunt of an old hack by the ANSI (Agence Nationale de la Sécurité Informatique - National Agency for IT Security) saying :
- Since we now have more important prerogatives (very recent change) this kind of attack won't happen again
- Also, we need more money
- And, that will teach you about not following our recommendation. Next time you WILL use an open source alternative to Adobe Reader.
Smart move but the tech part of the story is irrelevant.
