Arbitrum 生態永續合約去中心化交易平台 AFX Trade 遭遇安全事件。安全公司 Blockaid 表示,平台營運的 USDC 託管橋被攻擊,損失約 2,415 萬美元。 AFX 隨後暫停橋接服務,並啟動事件處置流程。

被盜資金已轉至以太坊

AFX 表示,具體攻擊路徑仍在調查中。鏈上安全機構 PeckShield 稱,攻擊者已將被盜 USDC 跨鏈轉至以太坊,並兌換為 12,468 枚 ETH,目前資金集中在一個地址中。

平台稱,受影響範圍目前僅限於 AFX 自行營運的託管橋,交易基礎設施、主網系統以及 Arbitrum 網路本身未受到影響。 AFX 也表示,正與生態合作者及安全機構合作追蹤資產流向。

Arbitrum 澄清原生橋未受影響

事件發生後,Arbitrum 聯合創始人 Steven Goldfeder 出面說明,Arbitrum 原生橋“沒有遭到任何形式的攻擊或利用”,相關異常交易來自第三方協議,而非網絡官方橋接設施。

這表態意在將事故範圍限定在單一應用層協定。若原生橋出現問題,影響通常會擴散至整個二層網路;而此次被攻擊的是建構在其上的獨立協議,風險相對局部。

AFX 向攻擊者提出返還方案

AFX 在公開溝通中提出解決方案:若攻擊者返還 70% 的資金,可保留其餘 30% 作為「白帽賞金」。這項做法近年在加密安全事件中並不少見,部分協議會以此爭取更高比例的資金回收。

這起事件也延續了 2026 年 DeFi 安全壓力。報導提到,今年 DeFi 領域因攻擊造成的損失已超過 8.4 億美元。就在一週前,Arbitrum 上另一家永續合約平台 Ostium 也因預言機金鑰被攻破而損失約 1,800 萬美元。
