跟进：63亿美元币安被盗案：FBI与美国特勤局介入调查，签名系统被攻破、约24亿美元资产恐难追回
据路透社报道，一名知情人士10月30日透露，全球最大加密货币交易所币安（Binance）正与全球多地执法机构合作调查63亿美元被盗案，合作方包括美国联邦调查局（FBI）和美国特勤局（USSS）。美国驻伦敦大使馆对此不予置评；特勤局未在非工作时间回应路透社的置评请求。
调查细节进一步浮现。美国区块链分析公司 TRM Labs 表示，攻击者攻破的是币安的「签名基础设施」——即批准交易的那套系统，得以发出指令掏空受影响的钱包。币安在社交平台 X 上表示，公司最初以为事件涉及一台被入侵的笔记本电脑，但后续调查已发现更多的入侵点，公司没有展开说明。
区块链记录显示，这起盗窃的大部分发生在周四（10月29日）格林尼治时间20时过后约20分钟内。资金被转走后，攻击者随即赶在币安合作方与稳定币发行商冻结之前把资产转移出去。
被盗资产中约一半是稳定币，现已被 Tether、Circle、Ripple 以及特朗普家族的加密企业 World Liberty Financial 等发行商冻结；冻结意味着攻击者难以把这部分资产变现，但并不等于这些币会自动返还币安。TRM 估计，约24亿美元的比特币与以太币已经无法追回——比特币与以太币没有发行方，任何公司都无法将其冻结。
另一家分析公司 Chainalysis 表示，上个月交易所 Bitget 被盗案的资金，正在与币安本案的赃款混合转移。
归因方面，TRM 表示，本案与去年交易所 Bybit 被盗案（FBI 当时归因于朝鲜黑客）特征相似，该公司高度确信本案出自同一伙人，即朝鲜精英黑客单位「TraderTraitor」。币安联合首席执行官 Richard Teng 表示，币安自己的调查尚未确认攻击者身份，损失将由用户安全资产基金（SAFU）与公司资源覆盖。朝鲜一贯否认参与网络攻击与加密货币盗窃，其驻日内瓦使团与驻华使馆没有立即回应置评请求。
市场继续受压。路透社称，周五加密货币价格下跌，稳定币总市值下降，显示有投资者正从数字资产中撤出资金。本站昨日已报道本案首篇：币安估计受影响资产约63亿美元、约30亿美元已被冻结、公司承诺全额赔付。完整报道见路透社：FBI与美国特勤局正与币安合作调查。

Follow-Up: FBI and US Secret Service Join Binance Hack Probe as Signing System Breach Emerges and $2.4 Billion Is Feared Beyond Reach
Binance, the world's largest cryptocurrency exchange, is working with law enforcement agencies around the world, including the Federal Bureau of Investigation (FBI) and the United States Secret Service (USSS), after hackers stole a record $6.3 billion from the platform, a person familiar with the situation told Reuters on Friday, October 30. The US embassy in London said it had no comment, and the USSS did not respond to a request for comment sent outside US hours.
New details of the breach have emerged. US blockchain analytics firm TRM Labs said the attackers compromised Binance's "signing infrastructure," the system that authorizes transactions, allowing them to issue instructions that emptied the affected wallets. Binance said in a statement on X that it initially thought the attack involved a compromised laptop, but that its subsequent investigation had uncovered additional points of breach, without elaborating.
Blockchain records show the bulk of the heist unfolded in about 20 minutes, beginning shortly after 2000 GMT on Thursday. Once the funds were moved, the attackers raced to shift them beyond the reach of Binance counterparties and stablecoin issuers.
About half the stolen assets were stablecoins that have since been frozen by issuers including Tether, Circle, Ripple and World Liberty Financial, the Trump family's crypto venture. Freezing limits the attackers' ability to convert the assets into cash, but does not mean the coins will be returned to Binance. TRM estimated that about $2.4 billion worth of bitcoin and ether is beyond reach, because no company issues bitcoin or ether and no company can freeze either one.
Chainalysis said funds stolen in an attack last month on the exchange Bitget were being mixed with proceeds from the Binance breach.
On attribution, TRM said the breach shared characteristics with last year's attack on crypto exchange Bybit, which the FBI attributed to North Korean hackers, and that it was highly confident the same group, North Korea's elite TraderTraitor unit, was behind the Binance theft. Co-CEO Richard Teng said Binance's own investigation had not yet identified the attackers and that losses would be covered by the exchange's secure asset fund and company resources. North Korea routinely denies involvement in cyberattacks and cryptocurrency thefts, and its mission in Geneva and embassy in China did not immediately respond to requests for comment.
Markets remained under pressure: cryptocurrencies fell on Friday and the total market value of stablecoins declined, suggesting investors were pulling money from digital assets, Reuters reported. GSM reported the initial story on Thursday: Binance estimated the impact at about $6.3 billion, said about $3 billion had been frozen, and pledged to cover all losses.
