Binance drops SignalPlus API keys after potential hack

Dextape brief

By Dextape Desk · November 5, 2026

Binance has deleted every API key tied to SignalPlus, a crypto trading terminal, as a rapid protective step after a possible breach at that third-party firm. The exchange said on X its own systems are unaffected and user funds are still safe. Deribit also removed all SignalPlus keys over the suspected incident.

Binance told customers to check open positions and pending orders while awaiting SignalPlus's all-clear, and to enable IP whitelisting before reconnecting any API keys. It also asked outside partners to examine their security controls, watch for unusual activity and contact it quickly over concerns. SignalPlus, which works with Bybit, Gate.io and OKX, had not responded publicly, and its press email was unreachable.

Why it matters: It shows how a breach at one integrated third-party tool can prompt exchanges to cut off access, coming as several exchanges report hacks this month.
