I have some news regarding this topic:
Just before B7 was 'hacked', I sent some euros to them. These were now returned to me, with the comment that it was a compensation for a fraudulent foreign transaction! The comment was in my local language, not in English or Hungarian or Bulgarian.
Is it possible that the authorities are on this case? If so, what should we expect?
It could be your bank being overly cautious about foreign money transfers?
It does seem like too much of a coincidence though.
