Binance Revokes Signalplus API Access Days After $6.34B Hack

Binance revoked all API keys linked to third-party trading platform Signalplus on Nov. 5, 2026, after Signalplus flagged a potential security issue. The exchange said its own systems were unaffected and customer funds remained safe. The move came a week after the Oct. 29 Binance hack, in which attackers reportedly compromised $6.34 billion. The revocation highlights how exchanges are tightening third-party access following the industry's largest recent breach. Traders and integrators using Signalplus via Binance API connections face disrupted order routing until access is restored. What to watch next: Signalplus's findings on the root cause and whether Binance extends the API freeze to other third-party providers.
