2025年加密貨幣失竊27億美元再創新高，北韓駭客成頭號公敵
2025年加密貨幣駭侵損失創下27億美元新紀錄。北韓駭客被指為Bybit交易所14億美元失竊案的元兇，凸顯出去中心化金融（DeFi）面臨的嚴峻安全挑戰。
年度失竊金額高達27億美元。根據多家區塊鏈監測公司的數據，2025年因駭客攻擊造成的加密貨幣損失已創下歷史新高。數十起竊案席捲了多家加密貨幣交易所及DeFi（去中心化金融）項目，由國家級駭客主導的攻擊行動更是變本加厲。
史上最大宗：Bybit 交易所駭侵事件
今年災情慘重的關鍵，是針對杜拜加密貨幣交易所Bybit的攻擊。駭客竊取了價值約14億美元的加密資產，不僅是史上已知的最大宗加密貨幣竊案，也是人類金融史上規模最大的劫案之一。區塊鏈分析公司與美國FBI皆指控，北韓政府支持的駭客是此次大規模攻擊的幕後黑手。在此之前，最高紀錄分別是2022年針對Ronin Network的6.24億美元，以及針對Poly Network的6.11億美元損失。
竊盜總額攀升，產業防不勝防
根據TechCrunch取得的數據，Chainalysis和TRM Labs兩家公司均估計2025年的總失竊金額為27億美元。Web3資安公司De.Fi也提出了相同的數字。Chainalysis還指出，另有70萬美元是從個人錢包中被盜。近年來駭侵事件的損失逐年攀升，2024年為22億美元，2023年則為20億美元。
據信，北韓利用竊取的加密貨幣為其受國際制裁的核武計畫提供資金。Chainalysis與Elliptic估計，光是2025年，北韓駭客就竊取了至少20億美元，而自2017年以來的累計竊盜金額已高達約60億美元。
