Hardware Ready Ready to Bench?
On November 5, 2026, Binance removed trading connections with the third-party platform SignalPlus. This decision was made as a precautionary measure following a security warning and confirmation from SignalPlus that it had suffered a cyberattack. Simultaneously, Deribit also revoked the service’s API keys. The internal attack on SignalPlus began on November 4, 2026.
Why it matters
The incident highlights the risks associated with integrating external platforms with major exchanges. Binance clarified that its internal systems and user funds were not affected by the warning, but urged the community to verify their accounts. For SignalPlus, the incident entails a temporary suspension of service until full security verification of the infrastructure is complete. The platform stated that the service will remain inaccessible until the full security of the systems is confirmed.
The numbers
According to Cointelegraph and Protos, losses suffered by SignalPlus users due to the breach amount to less than $82,000. The platform stated that it would fully reimburse the amounts stolen. Sources differ slightly on the extent of the sums: Cointelegraph indicates a value close to 82,000 USD, while Protos specifies that the amount is lower than this figure. In the broader industry context, Protos reports that BitMart suffered a hack for approximately $391,000 in the same period.
What remains to be understood
The attack vector was identified as a chain of compromises: according to SignalPlus, attackers exploited a compromised Telegram account of a partner to send fake meeting invitations on Microsoft Teams. This allowed them to access the computer of a platform engineer. The incident occurs in a critical context for the sector: Protos reports that Binance is still managing the consequences of a previous cyberattack that occurred at the beginning of the month, with stolen funds estimated between $6.3 and $6.4 billion depending on sources. Furthermore, other exchanges such as BitMart and Mercado Bitcoin were also hit in the same period.
