Cryptocurrency exchanges took defensive action by purging all API keys tied to SignalPlus after the trading infrastructure firm reported an internal security issue. Binance confirmed its systems and user balances were completely unharmed, while Deribit reported that its own data and platforms showed no signs of compromise. In response, Binance founder Changpeng Zhao publicly recommended that traders manually revoke any active SignalPlus keys on alternative exchanges. The incident arrives after Binance managed $3.64 billion in user withdrawals following a prior breach tied by the FBI to North Korean hackers.
