Se o hacker não tiver pressa, ele leva tudo. Serão criados mecanismos de ocultação de capital no futuro, contra o Estado Maior. Ocultar capital será opcional um dia.
The Binance hacker has 18,270 BTC. That's more Bitcoin than Tesla holds. For comparison: Tesla: 11,509 BTC El Salvador: approximately 7,820 BTC Binance attacker: 18,270 BTC The stolen Bitcoin is worth roughly $1.4 BILLION. CoinDesk's latest blockchain investigation found the coins split across 19 wallets, with 17 holding exactly 1,000 BTC each. And unlike USDT or USDC, Bitcoin has no central issuer that can simply freeze those addresses. Recovering this portion is going to be considerably harder.

Será cada vez mais difícil tirar mudar isso. Há um incentivo mto alto pra agir como esse cara, se você abre mão de valores. Blockchain não é melhor ou pior, mas diferente. Trás prós e contas, e um dos contras é esse. Pra ser gênio, não precisa ser do bem.
🫠 DER BINANCE-HACKER WAR SMARTER ALS GEDACHT Der Binance-Hacker hat einen der schlauesten Züge gemacht, die ich in Krypto bisher gesehen habe. Zuerst sperrt Tether 1,77 Milliarden USDT. Dann sperrt Circle 825 Millionen USDC. In dem Moment sah es so aus, als säße er auf totem Geld. Aber genau damit hatte er gerechnet. Einen Teil der USDT hat er gar nicht erst in der Wallet liegen lassen. 60 Millionen hat er bei Aave als Sicherheit hinterlegt und sich dagegen 19.762 Ether geliehen. Dann war er weg. Und jetzt wird es richtig verrückt. Tether kann USDT in einer Wallet sperren. Geliehenes Ether kann niemand sperren. Aave hat die Märkte eingefroren, die 60 Millionen USDT liegen als Pfand fest. Der Hacker sitzt auf gut 44 Millionen Dollar in Ether. Zurückzahlen wird er diesen Kredit nie. Warum auch. Rechnet man es nach, hat er seine USDT zu rund 3.030 Dollar je Ether verkauft. Ether steht bei 2.240. Ein miserabler Kurs. Aber 44 Millionen sind mehr als null. Und null wäre es gewesen, wenn die USDT in der Wallet geblieben wären. Zwei Firmen haben in Minuten Milliarden eingefroren. Einer, der DeFi verstanden hat, ist trotzdem mit einem Teil rausgekommen. Und das war nur die kleine Nummer. Über eine halbe Million Ether und 18.270 #Bitcoin konnte ihm sowieso niemand sperren.

A tal prova de reserva passa por aqui. Mostrar transação pública no perfil, pra que não só os especialistas pesquisadores vejam, mas todos que seguem, agrada. Simples: compare a gestão de crise de Binance vs Ledger. Bizarra a diferença.
Update: SAFU fund transfer is complete - this was the large 7,499 $BTC transfer visible here: blockchair.com/bitcoin/trans…

Olha, isso é bizarro. Não coloco a mão no fogo por nenhuma empresa cripto, mas os caras foram brabos aqui. Mta empresa ia começar com show de vítimismo e desculpa pra não cobrir o erro.
BREAKING: Binance says it already replenished 90% of the $6.3 BILLION lost in the crypto hack. 10 cryptocurrencies, including $BTC, $ETH and $SOL, are now fully backed. HUGE WIN FOR CRYPTO! 🚀

Binance deu aula na gestão pós crise. - Sofreu o maior hack da história cripto. - Anunciou tudo publicamente, várias vezes. - Perdeu 6,3 bi dólares em minutos. - Congelou metade do roubo, via parceiros. - Vai cobrir todos os 6,3 bilhões de dólares. - Vai publicar as Provas de Reserva. - Nenhum cliente vai perder moedas.
Binance has begun recovering affected assets for users and continues to work with law enforcement, issuers, blockchain intelligence firms and industry partners to trace, freeze and recover additional funds. The company has already publicly committed to cover losses through company funds in the prior announcement. Binance has already reserved over $6.34B of company funds to cover this incident. $5B of these funds are already held in the exact token assets that were impacted. We are completing the purchase of the remaining amount by buying token assets through market channels and OTC channels. We are doing this to match the format of the remaining token assets and address any asset shortfalls. This step can take longer because some tokens may have low liquidity and OTC settlement also takes time. We will share more progress as soon as we can. These figures do not include frozen or protected assets, which remain subject to ongoing recovery and verification. Currently, $3bn has been frozen, with thanks to our industry partners. We are working with partners and law enforcement to recover the frozen assets.We will continue to use company resources to cover confirmed shortfall and will provide further verified updates as recovery efforts progress. Ultimately, all user funds will be verified publicly through our Proof of Reserves. We will weather this storm. Thank you for the support.

Trezor com implante. Absolutamente nada está seguro em cripto.
CryptoBilis update We've been made aware, through responsible disclosure, of a single hardware implant in a Trezor Safe 5 device bought from the reseller CryptoBilis in August 2026. No CryptoBilis buyer has reported a loss of funds to us. IMPORTANT: If you bought a Trezor from CryptoBilis from March 2026 onwards, we know this is unsettling. Here’s what to do: Already using it? Move your funds to a newly created wallet with a new seed as soon as possible. Do not reuse the old seed in any wallet, hardware or software. If you don’t have another secure hardware wallet available, we recommend temporarily migrating your funds to a software wallet or an exchange you are familiar with. Not set up yet? Don’t set it up, and never enter your existing wallet backup on it. We haven’t received the device to confirm this report, but based on the customer’s description, we’re treating it as credible and sharing it now so customers who purchased a Trezor via CryptoBilis can secure their funds as a precaution. Our security team will examine the device as soon as it arrives. On October 9, 2026, we removed CryptoBilis as a reseller following reports of tampered Ledger devices sold through it. Since then, we have been inspecting Trezor devices that customers bought from CryptoBilis and have found no signs of tampering on any of the four devices we’ve received so far. NEVER share your wallet backup (recovery phrase) with anyone. Trezor Support will never ask for it. If you are affected by this incident, please keep your CryptoBilis device and contact Support to receive a new Trezor hardware wallet: trezor.io/support#open-chat We're investigating and will post updates here as soon as we know more. Thank you to the customer who reported this through our responsible disclosure program, and to @SEAL_911 for working alongside our teams on the response. Reports and engagement like this help us protect everyone else. For more information, visit our blog: trezor.io/blog/news/implant-…

Especialistas imaginam o Dia D acontecendo por conta do avanço do computador quantico. Ele descobriria senhas e burlaria sistemas. Em tese, ainda demora anos. Porém, enxames de IA poderiam atacar sistemas frágeis ou com falhas e criar o Dia D antes! Dia D seria o 1º dia do caos.

Se esse cara estiver certo, fodeu. O Dia D não será quântico, mas agentivo.

Hi Nikita. I’m an AI researcher for one of the big 3 labs. I can assure you, it’s about to get a lot worse. We’ve been assisting the US in combating agentic swarms on the US electrical grid. It’s about to get a lot worse. Pay attention to the banks next week.

Segurança agora importa mais que ticker. Quem pegar, pegou.
This is not just a crypto hack. It's a warning for the entire web. Banks, governments, hospitals, payment apps.. We've just witnessed firsthand that all of it runs on code that can be exploited. Security is about to become the most important industry in the world.

Aave virou alvo de Exit Liquidity DE NOVO! É um prato cheio pra hackers que buscam liquidez. Algum mecanismo novo precisa ser criado. Os outros projetos DeFi não vão ficar salvando a Aave.
Lo de el hackeo a Binance tiene una parte complicada. Tether congeló $1.570M en USDT y Circle más de $800M en USDC. Pero el hacker hizo una jugada bastante inteligente: utilizó $60M en USDT como colateral en Aave y sacó casi 20.000 ETH prestados. Puedes congelar los USDT, pero no los ETH que ya se llevó. Y aquí viene lo interesante: si no paga el préstamo y el colateral queda congelado, ¿quién asume las pérdidas? El riesgo no desapareció, se lo pasaron a DeFi. 👀

Isso é bizarro, absurdo, inacreditável. Quem não está estranhando o momento global está alienado. E ele está certo.
Comida, água, energia, equipamento médico e de comunicação, tudo comprado já. Agora é só garantir mais algumas armas e munições. 👊

O futuro de crypto é centralizado. Prós e contras estão na mesa, a concentração deve aumentar.
The Arbitrum Security Council has taken emergency action to rescue the 74,559,805 ARB and 8,425 ETH being held in the address on Arbitrum One that is identified as connected to the Binance exploit. The Security Council acted by weighing its commitment to the security and integrity of the Arbitrum community and Arbitrum governance without impacting any Arbitrum users or applications. After significant technical diligence and deliberation, the Security Council identified and executed a technical approach to move funds to safety without affecting any other chain state or other Arbitrum users. As of October 30, 2026 time, the funds have been successfully transferred to an intermediary frozen wallet. They are no longer accessible to the address that originally held the funds, and can only be moved by further action of the Security Council or a vote of Arbitrum DAO governance, which will be coordinated with relevant parties.

Saques suspensos. A pior coisa que poderia acontecer agora, é uma corrida de saques. Se a Binance fica insolvente, é papo de algo maior que FTX. Não creio que vá acontecer.
Binance will cover all losses. As a precaution, all deposits and withdrawals are temporarily suspended while our team conducts security checks, freezes funds, and works with law enforcement. We are working around the clock and will share a full post-mortem once the investigation is complete. Please rely only on official Binance channels for updates.

Fiz 3 semanas de testes. Agora, defini minha estratégia pra pontuar na @TxFlow_L1 ! Deixo aqui o print pós testes, semana que vem é pra esse custo baratear pelo menos 2x. Estimei $100M de FDV e 20% de Airdrop, isso dá $0,50 por ponto. Esse site dá pra fazer contas. É o airdrop que mais to dando atenção. E vocês?
Season 1, Epoch 2. 1,250,000 points have been distributed across 6,086 accounts this week.

Qual hardwallet vocês recomendam?
Correction: I said @Ledger didn't talk about the implant situation at all despite knowing about it - they did publish an academy topic in March 2026 that talks about it and recommends buying direct or from Authorized Resellers. ledger.com/academy/topics/le…

O CEO da Ledger me fez repensar.. Se continuo ou não usando e confiando em carteiras Ledgers. Comprar novas, não irei. As que tenho, não é só enterrar. Tem que atualizar e manter updates. Que trágico!
I should have said that your track record as CEO makes that you lack credibility in judging such events. Your experience of total failure doesn't make you an expert in judging Ledger's situation. And also... You are no white knight. I stand by that. We can talk next week as planned, I don't mind a strong conversation, I am available.
