一句话总结: 2026 年 10 月 29 日,约 63 亿美元从币安(Binance)的钱包转出,大部分在约 20 分钟内完成。没有任何东西被破解:区块链没有被攻破,币安也没有发现私钥泄露的证据。它的初步调查结果指向一名 DevOps 工程师被入侵的笔记本电脑,攻击者由此接触到一个被信任可以提交提现的服务。这些转账绕过了正常的审批,走的是合法的通道,所以看上去可能很平常。两家分析公司怀疑是朝鲜的 TraderTraitor,但这一点尚未得到证实。
发生了什么
"The estimated total impact sits at around $6.3B,"(估计总影响约为 63 亿美元。)币安在 10 月 30 日的安全通报中这样说。BBC 称之为"what is thought to be the largest hack in history - worth up to $6.3bn (£4.7bn)"(被认为是史上最大的黑客攻击,金额高达 63 亿美元(47 亿英镑))。
作为对比,BBC 网络安全记者 Joe Tidy 列出了此前的纪录:"Last year $1.5bn (£1.12bn) was taken from Bybit. Before that it was $600m (£433m) from Poly Network in 2021 and $540m (£412m) from Ronin in 2022."(去年,Bybit 被盗 15 亿美元(11.2 亿英镑)。在此之前,是 2021 年 Poly Network 被盗 6 亿美元(4.33 亿英镑),以及 2022 年 Ronin 被盗 5.4 亿美元(4.12 亿英镑)。)
速度很快。TRM Labs 说:"On October 29, 2026, an attacker moved approximately USD 6.36 billion out of Binance wallets on ten blockchains, most of it in about 20 minutes starting at 20:05 UTC"(2026 年 10 月 29 日,一名攻击者从币安在十条区块链上的钱包转走了约 63.6 亿美元,其中大部分是在 UTC 时间 20:05 起的约 20 分钟内完成的)。正如 TRM 的 Ari Redbord 对 BBC 所说:"That speed is the product of long preparation."(这种速度是长期准备的结果。)
不是区块链,也不是私钥
出人意料的是没被攻破的那部分。BBC 的 Mitchell Labiak 说:"The short version is that the blockchain wasn't hacked. Rather, the exchange on which people trade cryptocurrency was hacked."(简单说,被黑的不是区块链,而是人们用来交易加密货币的交易所。)
币安也说:"We have found no evidence of any wallet private key leak."(我们没有发现任何钱包私钥泄露的证据。)
起点可能是一台笔记本电脑
币安的初步答案是:"Binance's initial investigation suggests that the security incident may involve a compromised DevOps engineer's laptop, which allowed an attacker to gain access to a service container and submit unauthorized withdrawal transactions."(币安的初步调查显示,这起安全事件可能涉及一名 DevOps 工程师被入侵的笔记本电脑,攻击者借此进入一个服务容器,并提交了未经授权的提现交易。)
也可能不止一台机器。币安联席 CEO Richard Teng 通过 BBC 表示:"This was not carried out by one person. Our initial investigation suggested that the security incident may have involved a compromised laptop, however our subsequent investigation has uncovered additional points of breach."(这不是一个人干的。我们的初步调查显示,这起安全事件可能涉及一台被入侵的笔记本电脑,但后续调查又发现了更多的入侵点。)
币安没有公布攻击者是怎样进入那个服务的,本文也不做猜测。
为什么难防
Teng 还说,这些转账"did not pass through our normal approval controls"(没有经过我们正常的审批控制)。
Aikido 的 Mackenzie Jackson 向 BBC 描述了大致的路径:"From one laptop, an attacker can open one internal system, then another, until they reach a service trusted to send out withdrawals. Those withdrawals travel through a legitimate route, so they can look routine."(攻击者可以从一台笔记本电脑打开一个内部系统,再打开另一个,直到找到一个被信任可以发出提现的服务。这些提现走的是合法通道,所以看上去可能很平常。)
BBC 对 Jackson 观点的概括是:"He says hackers have shifted from going after company infrastructure to going after the machines of the people who run it. Those machines hold the digital keys that unlock a company's systems, so an attacker can act as that engineer."(他说,黑客已经从攻击公司的基础设施,转向攻击运维这些设施的人所用的机器。这些机器上存着打开公司系统的数字钥匙,所以攻击者可以冒充那名工程师行事。)
是谁:被怀疑,未证实
TRM Labs 通过 BBC 表示:"Several features of this attack match earlier North Korea-linked heists"(这次攻击的若干特征,与此前和朝鲜有关的盗窃案相吻合)。其中之一就是 Bybit。FBI 称:"North Korea was responsible for the theft of approximately $1.5 billion USD in virtual assets from cryptocurrency exchange, Bybit, on or about February 21, 2025."(朝鲜应对 2025 年 2 月 21 日前后从加密货币交易所 Bybit 盗取约 15 亿美元虚拟资产一事负责。)
对于币安这起事件,两家分析公司点出了嫌疑对象。TRM Labs:"TRM attributes the attack to TraderTraitor, North Korea's elite hacking unit, based on robust on and off-chain intelligence. We make this judgment with high confidence."(基于可靠的链上和链下情报,TRM 将这次攻击归因于朝鲜的精英黑客部队 TraderTraitor。我们对这一判断有很高的把握。)Chainalysis:"Chainalysis investigators assess the $6.4 billion hack of Binance … to be the work of North Korean cybercrime group TraderTraitor."(Chainalysis 的调查人员评估认为,币安 64 亿美元被盗一案……是朝鲜网络犯罪组织 TraderTraitor 所为。)
但 Elliptic 指出:"No government or law enforcement agency has confirmed attribution, and Binance has not commented on who was responsible."(没有任何政府或执法机构确认归因,币安也没有就谁该负责发表评论。)BBC 也说:"We don't yet know who was behind the attack"(我们还不知道谁是这次攻击的幕后黑手)。所以:被怀疑,未证实。
之后发生了什么
币安"temporarily suspended withdrawals while security checks are completed"(在完成安全检查期间暂停了提现),并表示:"Binance will cover all losses from the SAFU fund and the company's funds. User funds are safe."(币安将用 SAFU 基金和公司资金弥补全部损失。用户资金是安全的。)它还通报:"We have worked with blockchain partners to freeze affected assets, with ~$3 billion frozen on-chain so far."(我们已与区块链合作伙伴一起冻结受影响的资产,目前链上已冻结约 30 亿美元。)
时间很关键。盗窃只用了几分钟,洗钱却要几周。Chainalysis:"Following major theft events between 2022-2025, stolen funds follow a structured, multi-wave laundering pathway that unfolds over approximately 45 days"(在 2022–2025 年间的重大盗窃事件之后,被盗资金会沿着一条有组织、分多波进行的洗钱路径流转,整个过程持续约 45 天)。说到规模:"North Korean hackers stole $2.02 billion in cryptocurrency in 2025, a 51% year-over-year increase"(2025 年,朝鲜黑客盗取了价值 20.2 亿美元的加密货币,同比增长 51%)(Chainalysis)。
而追回资金很慢。关于 Bybit,事发 18 个月后,Decrypt 报道"around $48.4 million has been recovered and about $30.5 million frozen across more than 28 exchanges and custodians"(在超过 28 家交易所和托管机构中,约 4840 万美元已被追回,约 3050 万美元被冻结)。也就是 15 亿美元里大约追回了 3%(我们自己算的:4840 万美元 ÷ 15 亿美元)。
补救办法
- 在发起请求的系统之外审批。 FBI 建议,在转移公司任何金融资产之前,"Require multiple factors of authentication and approvals from several different unconnected networks"(要求多因素认证,并要求来自多个互不相连的网络的审批)。
- 拆分谁能签什么。 TRM Labs:"Signing infrastructure and approval paths should be separated by chain and wallet tier."(签名基础设施和审批路径应按链和钱包层级分开。)
- 锁定靠近资金的机器。 "For companies with access to large quantities of cryptocurrency, the FBI recommends blocking devices connected to the company's network"(对于能动用大量加密货币的公司,FBI 建议禁止连接到公司网络的设备)下载或运行任何未经批准的程序。
最大的盗窃案并不破解加密技术;它们接管的是被信任来转移资金的那套流程,而这套流程要经过人,以及人的笔记本电脑。
