what happened
Binance and Deribit said on Thursday they had revoked every API key tied to SignalPlus, a platform for crypto options and derivatives, after it flagged a possible security problem. Binance said its own systems were not affected and user funds remain secure. Deribit said its investigation turned up no sign that its systems or data were compromised.
Binance founder Changpeng Zhao urged anyone using SignalPlus with other exchanges to revoke their API keys immediately, writing on X. The move comes a week after Binance customers withdrew $3.64 billion, or 2.1% of assets, when the exchange restarted on Sunday following a hack that the FBI links to North Korea, which stole billions of dollars. Binance said it covered 95% of the $6.3 billion stolen.
