- Binance e Deribit revogam chaves da SignalPlus após alerta de segurança — this brief
Binance revogou todas as chaves API conectadas à SignalPlus após a plataforma de negociação de opções reportar um possível incidente de segurança. A medida, tomada em 5 de novembro de 2026, interrompeu o acesso automatizado que alguns clientes usavam para operar em suas contas na exchange. A Deribit também desconectou a SignalPlus, confirmando que as duas maiores integrações citadas pela imprensa foram neutralizadas preventivamente.
A resposta ocorreu enquanto as exchanges conduziam avaliações sobre o alcance do problema. A Cryptopolitan informou que a Binance considerava limitada sua exposição à plataforma de opções baseada em Hong Kong, embora as conexões dos clientes institucionais tenham sido removidas. Crypto EconomyIntr reported that users were instructed to inspect open positions and pending orders directly on the exchange and wait for confirmation that the issue had been resolved.
As duas exchanges afirmaram que seus próprios sistemas estavam intactos. Blockonomi, 
Bitcoin.com e Decrypt registraram a assurances from Binance that customer funds remained safe; none of the coverage supplied said whether any unauthorized activity actually took place. CryptoPotato added that the cutoff halted trades, monitoring tools, and automated strategies that SignalPlus users had been running through Deribit.
The precise technical cause was not disclosed in the summaries reviewed. U.Today characterized the event as a security vulnerability, while Crypto Adventure, Crypto Economy, Blockonomi, Bitcoin.com, and Crypto.news described it more cautiously as a potential security issue or warning. Crypto.news also reported a warning from Binance founder Changpeng Zhao that traders using SignalPlus with other exchanges should take similar precautions and disconnect the integration.
Reports also placed the revocation shortly after a separate attack on Binance. Bitcoin.com said the action came one week after a US$ 6.34 billion hack on October 29, 2026, while Decrypt cited US$ 6.4 billion and attributed the earlier attack to North Korea. Those accounts provide timeline context for the heightened security response, but the supplied coverage did not establish any technical link between that hack and the SignalPlus warning.
The broader crypto market was broadly higher in the supplied snapshot. Total market capitalization stood at US$ 2.73 trillion, Bitcoin was up 1.86% over 24 hours, and the Fear & Greed index registered 50, classified as Neutral. 
JUST traded at US$ 0.142258, gaining 1.25% in 24 hours and 0.71% over seven days, with a market capitalization of US$ 1.14 billion. The immediate items to monitor are the nature of the security issue, whether any unauthorized activity is confirmed, and when affected integrations and automated functions are restored.
Since this brief published about 2 hours ago, JUST (JST) has moved from R$0,777960$0.1423 to R$0,777839$0.1422 — -0.02%.
The chart plots JST's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from Criptano's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Não é recomendação.
At today's peer-to-peer rate, 1 JST ≈ R$0.779098 (about $0.1422), up 1.6% over 24 hours. The real itself trades about 0.2% above the official rate on the P2P market, so a Brazilian buyer's effective cost differs from the headline dollar price.
