@OP you can close this thread as we can assume the problem has been solved already
The hackers do not want to provide the private key and also asking for 500000$ as bounty pool for delivering the funds back to the protocol. So, now the drama is on higher level and the fund would not be available if it can be withdrawn as well as if it could be sold.
