Not for the moment. But i have heard things like that from another people, so be careful with ur coins in cryptsy, and in another places.
Maybe can be just an error, or can be really stolen...
Be careful with your coins everywhere:
1) If you have to use Windows, do everything you can to make sure the machine isn't infected
2) Never open a Java app in a website (much malware installed this way)
3) Don't keep all your coins online - keep the minimum online - the rest in wallet
4) Enable 2FA on any website you keep coins at
