A natural evolution in the cyber criminal world i would say as it was evolution for us to use the cloud for file storage and transactions.
A worrying thought for that to be happening and hopefully the security guru's have a handle on this already and learn the criminal system and how it works and give a solution/s to overcome this and employ relevant countermeasures.
The security community seems to know about this and should have already put in place countermeasures to the problem.
