They say the story isn't true, but the source they cite in the very next sentence says:
Das Beispiel, das wie ein Hollywood-Szenario daherkommt, hat sich wirklich so zugetragen. Es zeigt, wie vielseitig digitale Angriffe geworden sind.
(This example, which sounds like a Hollywood plot, really happened. It shows how ~~multidimensional (my mind blanks on a better translation right now)~~ EDIT: diverse cyber attacks have become)
Edit: I hate microblogging sites. Apparently the thread continues on and the company who made the statement in the cited article has backtracked and admitted that this was a hypothetical. It did not happen.
