I also got hit by 13R87ropkDKzDEuVeQoX64kkcLvPWVdTKH, Lost 0.00120115 BTC that didn't get a chance to withdraw.
What is even more scary is they got by the 4-digit PIN that is MANDATORY to set. 
Clearly there is a big security issue here, Most likely several of the Boxes running Hashcows have been r00ted. Clean back-ups should be restored and the servers wiped and rebuilt.
It would be nice to have compensation.
Oh yah no doubt they have had a full compromise.
It will be interesting to see if they figure out how, and whether they know how to fix it and whether they disclose how it happened.
We'll learn a lot about hashco.ws's in the next few days...
