Cryptocurrency exchange Binance halts trading after detecting irregular SYS trading activity
Binance -- the largest cryptocurrency exchange in the world -- temporarily halted all trading after it detected "irregular trading on some APIs".
As a precautionary measure, the exchange removed all existing API keys and asked users to re-create theirs from their accounts. The measure meant a suspension of trading, withdrawals and other account activity. The matter is related to the Bitcoin fork Syscoin which halted deposits and withdrawals, but Binance stressed that there had not been as hack and that its blockchain is safe.
Both Binance and Syscoin have promised that more information will be shared soon about what happened. It's not clear whether the delay in publishing this information is because an investigation is still underway, or because details cannot be shared for security reasons until additional measures have been put in place.
