多重簽名錢包被攻陷,損失高達4000萬美元




攻擊者在多簽錢包創建後數分鐘內接管,慢慢抽走高達4000萬美元的資金

根據法醫分析,一名攻擊者在44天前創建的某個鯨魚多簽錢包後,僅幾分鐘內便接管了該錢包,並自此開始慢慢抽走資金。

區塊鏈安全公司PeckShield在周四的一篇帖子中報導,這個鯨魚的多簽錢包因私鑰被洩露而損失約2730萬美元。PeckShield指出,攻擊者已通過Tornado Cash洗錢約1260萬美元,或4100個以太坊(ETH),並保留了約200萬美元的流動資產,同時還在Aave上控制了一個槓桿長倉。

然而,Hacken Extractor的法醫負責人Yehor Rudytsia的新發現顯示,總損失可能超過4000萬美元,且事件可能早在更早之前就已開始,最早的盜竊跡象可追溯至11月4日。

Rudytsia告訴Cointelegraph,標記為“被攻擊”的多簽錢包可能從未真正由受害者控制。鏈上數據顯示,該多簽錢包是受害者於11月4日早上7:46(UTC)創建的,但六分鐘後便轉移給了攻擊者。Rudytsia表示:“很可能是盜竊者創建了這個多簽錢包並將資金轉入,然後迅速將所有權轉移給自己。”

攻擊者耐心地進行資金洗錢

一旦控制了錢包,攻擊者似乎採取了耐心的策略。他們在幾週內分批進行Tornado Cash的存款,從11月4日的1000 ETH開始,並在12月中旬以較小的、錯開的交易持續進行。根據Rudytsia的說法,仍有約2500萬美元的資產在攻擊者控制的多簽錢包中。

他還對錢包的結構表示擔憂。該多簽錢包被配置為“1-of-1”,這意味著只需一個簽名便可批准交易,“這在概念上並不符合多簽的定義,”Rudytsia補充道。

Hacken的去中心化應用(DApp)審計師Abdelfattah Ibrahim表示,仍然存在多種攻擊向量,包括簽名者設備上的惡意軟件或信息竊取者、釣魚攻擊以欺騙用戶批准惡意交易,或不良的操作安全實踐,例如以明文存儲密鑰或在多個簽名者使用同一台設備。

“防止這種情況發生的辦法是將簽名設備隔離為冷設備,並在用戶界面之外驗證交易,”Ibrahim說。

AI模型能夠進行智能合約攻擊

正如Cointelegraph報導的,Anthropic和機器學習對齊與理論學者(MATS)小組最近的研究發現,當前的領先AI模型已經能夠開發出真實的、盈利的智能合約攻擊。

在受控測試中,Anthropic的Claude Opus 4.5、Claude Sonnet 4.5和OpenAI的GPT-5共同生成了價值460萬美元的攻擊,顯示出使用商業可用模型進行自主攻擊在技術上是可行的。

在進一步測試中,Sonnet 4.5和GPT-5針對近2850個最近推出的無已知漏洞的智能合約進行了測試。這些模型發現了兩個先前未知的零日漏洞,並生成了價值3694美元的攻擊,略高於生成它們所需的3476美元API成本。

這一事件不僅揭示了加密貨幣世界的安全漏洞,也反映出攻擊者在技術上的創新與耐心。隨著加密市場的持續擴張,這類事件將成為未來監管和安全措施的重要焦點。如何在不斷變化的環境中保護資金安全,將是每位投資者和開發者必須面對的挑戰。

Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a striking, high-resolution portrait of a young woman with long, flowing wavy brunette hair, seated gracefully on a simple black wooden chair in a dimly lit studio. She wears an oversized, off-white knitted sweater that drapes loosely over her frame, slipping off one shoulder to reveal smooth skin and add a subtle touch of sensuality. Her pose is elegant and contemplative: one arm rests gently on the chair’s backrest while her hand delicately supports her chin, and her gaze is directed thoughtfully toward the side, creating an intimate and introspective mood. The lighting is expertly crafted with a single soft, directional light source positioned to the side, casting gentle shadows that sculpt her form and highlight the texture of the knitwear and the natural contours of her legs and arms. This chiaroscuro effect enhances the depth and dimensionality of the image, emphasizing the softness of her skin and the intricate weave of the sweater. The background is a smooth, muted dark gray, providing a minimalist and distraction-free backdrop that contrasts beautifully with her light-colored apparel and warm skin tones. *** The composition is a full-body vertical frame that captures the model’s seated posture with perfect balance, positioning her slightly off-center to create visual interest and harmony. The overall color palette is subdued and warm, featuring neutral tones that evoke a sense of calm and understated elegance. The image is impeccably sharp, showcasing fine details such as the delicate waves of her hair, the subtle folds in the fabric, and the natural texture of her skin. The style is classic and timeless, blending modern minimalism with emotive portraiture to convey quiet strength, beauty, and introspection. The person from the reference photo ( keep the face of the person 100% accurate from the reference image ) relaxing on a fluffy, glowing cloud high above the sky, surrounded by soft golden sunlight and vast layers of clouds stretching to the horizon. the person is lying back comfortably with a pillow, wearing a dark long-sleeve shirt, olive green pants, holding a book in one hand and a coffee cup in the other. the lighting is cinematic and warm, capturing the golden hour ambiance with radiant highlights and gentle shadows across the clouds. captured with a wide-angle lens at medium depth of field, balancing focus between the subject and the surrounding dreamy sky. the overall atmosphere is surreal and serene, blending realism with fantasy in a peaceful, imaginative setting. Transform the original photo into a dramatic, photorealistic, ultra wide-angle shot with an extreme camera angle (including views from directly below or above), where one or more body parts are right next to the lens and look huge, the rest of the body recedes in perspective, and the same person strikes a stylish, complex, powerful pose in a consistent, expanded version of the original environment. The woman in the photo is wearing yellow stilettos and a black and silver metallic ball gown and stylish black sunglasses.
