Binance cuts SignalPlus access after security alert for crypto traders
Binance has revoked all API keys linked to SignalPlus after the trading platform flagged a potential security issue affecting exchange connectivity. The move extends to broader market caution, with co-founder Changpeng Zhao urging users to remove the same keys from other venues while Binance says its own systems remain unaffected and customer funds are safe.
Highlights
- Binance cut SignalPlus API connectivity due to a potential security issue, stating its systems are unaffected and customer funds remain safe.
- Crypto derivatives exchange Deribit also disabled SignalPlus access, with Changpeng Zhao advising traders to revoke SignalPlus keys on all platforms.
- A $6.3 billion Binance hack and concerns about compromised API keys highlight growing operational risks for active crypto derivatives traders using third-party tools.
Precautionary shutdown of SignalPlus connectivity
According to CoinDesk, in a statement, Binance says it has severed SignalPlus access as a precaution after the platform reported a possible security issue. The exchange says its own systems are not affected, and it adds that customer funds remain safe.Binance tells SignalPlus users to review their positions and open orders directly on the exchange and to wait until the issue is resolved before reconnecting API keys. It also urges customers to monitor their accounts closely and confirm that their API credentials remain secure.
Changpeng Zhao, Binance's co-founder, warns traders to revoke SignalPlus keys on other exchanges as well. The summary of the alert notes that crypto derivatives exchange Deribit has taken similar action.
Security risks spread across crypto trading
Compromised API keys can allow unauthorized trades even when withdrawals are disabled, making third-party trading connections a persistent operational risk for crypto market participants. SignalPlus is known for digital asset options trading and offers users trading tools and market insights, which can make any disruption significant for active derivatives traders.The warning follows heightened scrutiny of security standards across the sector after Binance recently faced one of the largest hacks in crypto history, with about $6.3 billion stolen. Although roughly half of those funds are later frozen by other financial parties, the breach intensifies concerns about platform and connectivity risks across crypto trading.
Cybersecurity funding surged in Q3 2026, with global security and privacy startups raising $6.8 billion as larger late-stage rounds offset a decline in overall deal counts, our earlier report noted. The piece highlighted strong investor focus on AI-driven and identity-security companies, alongside accelerating consolidation through major acquisitions—signaling that concern about digital risk is still shaping where capital and strategic spending go.
