Bithumb Hacked for $30,000,000

I just saw this post on Twitter from the Bithumb account:
[Notice for the suspension of all deposit and withdrawal service]
We checked that some of cryptocurrencies valued about $30,000,000 was stolen. Those stolen cryptocurrencies will be covered from Bithumb and all of assets are being transferring to cold wallet.
