He Yi, a senior executive at Binance, stated that the exchange also encourages all third-party platforms integrated with Binance to review their security controls, monitor for abnormal activity, and contact immediately if any concerns arise, noting that this is a challenge no single company can address alone. Binance CEO CZ (Changpeng Zhao) added that anyone using SignalPlus on any trading platform should revoke all API keys, as storing API keys on third-party platforms is generally not recommended. Deribit also previously reported related incidents. Earlier, Binance announced that in response to potential security issues reported by third-party platform SignalPlus, it had taken preventive measures by actively revoking all API keys linked to SignalPlus. The exchange emphasized that its own systems were not affected and user funds remain secure. Binance reminded SignalPlus users to log in directly to their Binance accounts to check their holdings and open orders, avoid re-binding API keys until SignalPlus confirms the issue is fully resolved, and recommended always enabling IP whitelisting.

Deribit has notified users that after SignalPlus alerted it to a potential security risk, the crypto exchange took preventive action by removing API keys linked to SignalPlus from affected user accounts. No signs of compromise to its systems or data have been found in ongoing investigations. As a result, trading, monitoring, and automated operations run via SignalPlus have been halted. Deribit is advising affected users to log in directly to the platform to review open orders, positions, and recent account activity, and to wait until SignalPlus confirms connectivity can be restored before generating new API keys. New keys must have IP whitelisting enabled, and accounts should also enable two-factor authentication.
