Reason behind the Sudden Pump in SYS coin. Is SYS coin Hacked ???

It seems that Syscoin cryotocurrency blockchain has been compromised. It reason behind this is that more than one billion of its coin were mined in a single block. This is peculiar because the sys coin total supply is 888 million less than the mined amount in a single block.
Sys coin community confirmed on Twitter account that its blockchain has been compromised, and stated that they asked all the exchanges to stop the trading .
On Binance Exchange one single Sys coin was bought at price of 96 btc.
The redicuously high buy order placed on binance led to sudden pump in sys coin price.
