🚨 ¡El Atraco Silencioso!
Cómo un fallo de código de 2021 en #Coldcard permitió el robo de $38 millones en #bitcoin en solo 25 minutos
En una operación quirúrgica que ha sacudido la confianza en el "almacenamiento en frío", piratas informáticos lograron drenar aproximadamente 594 #bitcoins en una estrecha ventana de apenas 25 minutos. Lo más alarmante no es la velocidad del robo, sino el vector de ataque, una vulnerabilidad silenciosa que acechaba en las entrañas del firmware de las reconocidas carteras de hardware Coldcard desde hace más de cinco años.
La Ejecución del Robo: Entre las 01:31 y las 01:56 UTC del viernes, los atacantes vaciaron alrededor de 500 carteras (todas de firma única y con más de 0.15 BTC). Tras mover los fondos en una intensa ráfaga de transacciones, consolidaron 562 #BTC en una sola dirección que permanece inactiva. Muchas de las carteras afectadas llevaban años sin movimiento.
La Falla Fatal (El "RNG Gate"): Investigaciones del equipo de seguridad de Block revelaron un error catastrófico. A partir del firmware 4.0.0 (marzo de 2021), una configuración defectuosa anulaba el generador de números aleatorios por hardware del dispositivo.
Semillas Predecibles: En lugar de crear frases semilla matemáticamente imposibles de adivinar, el dispositivo utilizaba un software básico que tomaba como base el número de serie del chip y el reloj del sistema. Al ser datos públicos o fáciles de medir, los atacantes pudieron deducir las llaves maestras sin tocar físicamente los dispositivos.
Los Modelos en Peligro: Coinkite, el fabricante canadiense, emitió una alerta roja para los usuarios que generaron su semilla en un modelo Mk3 utilizando la versión 4.0.1 o posterior. El riesgo depende de la fecha de creación de la cartera (2021 - 2026), no de cuándo se compró el dispositivo. Análisis preliminares indican que los modelos más recientes (Mk4, Q y Mk5) no están afectados.

594 BTC trị giá 38 triệu USD biến mất chỉ trong 25 phút từ 500 chiếc ví lạnh tưởng chừng như an toàn nhất – một lời cảnh tỉnh đắt giá cho trường phái tự lưu trữ (self-custody).
Vụ hack nhắm vào lỗ hổng firmware cũ (từ bản 4.0.1 năm 2021) của ví Coldcard Mk3, khi thiết bị vô tình bỏ qua trình tạo số ngẫu nhiên phần cứng và chuyển sang cơ chế phần mềm dễ đoán. Dù sự kiện này chưa tác động trực tiếp đến đường giá BTC – vốn vẫn giữ trên mốc 64.000 USD, nhưng nó giáng một đòn mạnh vào tâm lý của các holder dài hạn. Khi những chiếc ví "offline hoàn toàn" cũng có thể bị khai thác từ xa do lỗi code, rủi ro hệ thống là điều chúng ta phải nghiêm túc nhìn nhận.
Góc nhìn của tôi là không có gì là an toàn tuyệt đối trong thị trường này. Nếu bạn đang dùng thiết bị Coldcard Mk3 đời cũ, hãy lập tức kiểm tra phiên bản firmware và chủ động chuyển tài sản sang địa chỉ mới nếu cần. Việc quản trị rủi ro bảo mật cũng quan trọng như việc quản lý vốn trên sàn đấu futures vậy. Hãy luôn cẩn trọng và tự nghiên cứu kỹ lưỡng.

🚨 LATEST UPDATE 🚨
A significant security breach has resulted in the loss of $38 million in Bitcoin. The theft was linked to a specific flaw found within Coldcard keys. Interestingly, the manufacturer of the hardware wallet believes that the vulnerability may have been discovered using artificial intelligence technology. 🛡️
This incident is a major development for the industry because hardware wallets are generally considered the gold standard for securing digital assets. When a trusted device faces a flaw that leads to millions being drained, it raises serious questions about the long-term safety of self-custody methods. Users are now paying closer attention to how advanced computing might impact cryptographic security. ⚠️
How do you feel about using hardware wallets for your long-term storage? 🔍

Общая капитализация крипторынка составляет $2,14 трлн. Уязвимость Coldcard: Эксперты зафиксировали массовый скоординированный вывод 594,5 BTC ($38,3 млн) с 500 адресов. Проблема связана со слабой генерацией сид-фраз на аппаратных кошельках #Coldcard Mk3 ЧМ-2026 и блокчейн: Прошедший Мундиаль сгенерировал рекордные $20 млрд объема на децентрализованных рынках прогнозов. В ставках приняли участие свыше 400 000 криптокошельков. Отчет Coinbase за II квартал: Биржа увеличила свою долю на мировом рынке до рекордных 10,3%.

🚨 COLD WALLET FLAW FORCES $38M $BTC EXODUS — 500 ADDRESSES IN MOTION ⚠️
📊 On-chain monitors just clocked a serious supply-side event: a Coldcard vulnerability pushed roughly 500 wallets to relocate 594.48 BTC — about $38.2M — in a single sweep. This isn't a market-wide hack; it's a security-driven liquidity reshuffle. 🔍 When hardware owners migrate en masse, the capital rarely stays off-grid — it funnels toward top-tier exchanges or OTC desks, which means latent sell pressure on the bid side.
🌊 The silver lining: these forced moves often create the very liquidity pools that institutions use to reload. Smart money watches for the exhaustion of such distribution before pressing bids. 💬 Do you treat a vulnerability-driven BTC move as bearish supply, or future buy-side fuel tank? 👇
⚠️ Not financial advice. Always manage your risk. 🛡️

🚨 $BTC MYSTERY SWEEP: $38.3M MOVED AS COLDCARD MK3 SEED FLAW EMERGES
594.48 BTC moved in surgical fashion — 1,324 UTXOs across 500 transactions inside just three blocks. 🦈 That level of precision smells less like random opportunism and more like institutional-grade automation targeting wallets with weak entropy.
Coinkite's Mk3 advisory zeroes in on firmware 4.0.1 to 5.0.3, urging affected users to migrate their seed phrases immediately. BIP-39 passphrase wallets carry lower risk, and Mk4/Q/Mk5 devices remain outside the blast radius. 🔍 Early theories point to a low-entropy RNG in a specific device batch, though the direct link to this sweep isn't confirmed.
Security researchers are still dissecting the root cause, but the lesson is already loud: self-custody rewards those who audit their generation source. 💡 Are you certain your cold wallet seed wasn't generated inside that vulnerable window? 👇
