Binance revoked all API keys connected to SignalPlus after the third-party trading platform reported a potential security issue, according to Crypto Adventure, Crypto.news, Decrypt and U.Today. Crypto Adventure dates the precautionary action to November 5. The revocation cuts SignalPlus off from automated account access on Binance, limiting what the external service could do through the permissions granted by users.
Deribit also moved to revoke API keys linked to SignalPlus, Crypto Adventure reported, extending the containment effort beyond Binance. SignalPlus supplies trading tools for cryptocurrency options and derivatives markets, so customers using those tools may have connected exchange accounts for automated execution. Revoking the keys closes that route without requiring users to remove SignalPlus from their own software first.
The four outlets agree on the central response: Binance withdrew the third-party API permissions associated with SignalPlus after a security warning. Crypto Adventure and Crypto.news describe a “potential security issue,” while U.Today characterizes the matter as a security vulnerability. No outlet provided evidence that customer funds were lost through SignalPlus, and Decrypt reported that Binance said its own systems and user funds were unaffected.
Crypto.news highlighted a broader warning from Binance founder Changpeng Zhao for traders who use SignalPlus with other exchanges to take comparable precautions. That detail matters because revoking Binance keys addresses only the Binance connection; users may have granted the same service access elsewhere. The reported action is therefore framed as a risk-control response rather than evidence of an exchange-system compromise.
Decrypt supplied additional context by saying Binance made the decision one week after the exchange suffered a $6.4 billion hack blamed on North Korea. That timing was not disputed by the other outlets, but it was the only report to connect the SignalPlus key revocations with the recent hack. The disclosure separates the immediate third-party warning from Binance's statement that its systems and customer funds remained unaffected.
The wider crypto market was broadly higher as the security response unfolded. Total market capitalization stood at $2.73 trillion, 
Bitcoin gained 1.65% over 24 hours, and the Fear & Greed index registered 50, corresponding to a neutral reading. The market data does not identify a price effect tied specifically to the SignalPlus warning, but it provides a neutral backdrop for an issue centered on API permissions and automated trading access.
