Binance Revokes Signalplus API Access Days After $6.34B Hack

Binance revoked all API keys linked to Signalplus on Thursday, Nov. 5, 2026, after the third-party trading platform reported a potential security issue. The exchange said its internal systems were unaffected, and customer funds remained safe. The precaution comes just one week after the Binance $6.34 billion hack on Oct. 29, when attackers reportedly compromised 17 hot wallets across multiple blockchains. Although the incidents occurred within days of each other, no evidence has established a connection between them. Binance pulled the plug on its Signalplus integrations after receiving notice of a possible security problem involving the external trading service.
