Above all it is a multi signature wallet and someone from the inside would be aware of any flaws in the system. As of now they have stopped all withdrawals but are still accepting fiat deposit.
As of now they announced bounty for whoever can help identify/recover the stolen funds and also I read that they contacted many exchanges all around the world to stop the funds funneling via their platform along with registered compliant with FIU.
So far there is no proper inimation given to users about this hack I opened their app they seem to be coninuing as usual which is red flag and not being transparent backs up there's something definitely going on inside.
For now better not to use the exchange at all until they gets cleared with this thing.
