这场安全危机,或许比想象中更加严重。

“您好,这里是 Coinbase 安全团队,检测到您的账户存在异常登录……”

电话那头的声音专业而急促,甚至能准确报出你的姓名、注册邮箱和最近交易记录。你会选择立即挂断,还是按照"客服"指引,一步步将资金转入所谓的"安全钱包"?

近日,多个 Coinbase 用户接连被骗,损失金额惊人。仅 3 月份,被盗资金已超 4600 万美元,每年 Coinbase 用户因社交工程诈骗造成的损失更是高达 3 亿美元。

然而,这些黑客究竟是如何精准锁定目标的?他们为何能获取用户个人信息?这场安全危机,或许比想象中更加严重。

诈骗猖獗,钓鱼攻击产业化

3 月 28 日,链上侦探 ZachXBT 披露,过去两周内,发生多起疑似 Coinbase 用户遭受诈骗的案件,使 3 月被盗资金总额超过 4600 万美元。

事实上,这类诈骗早已有迹可循。早在 2 月初,ZachXBT 就曾揭露, 2024 年 12 月至 2025 年 1 月期间,Coinbase 用户因类似手法损失高达 6500 万美元,这一数字让 Coinbase 面临着每年超 3 亿美元的社交工程诈骗危机。

根据 ZachXBT 的分析,诈骗手法已形成一条成熟的产业链:

  • 诈骗者冒充 Coinbase 官方

诈骗者使用伪造的电话号码拨打受害者电话,并利用用户个人信息获取信任。他们声称用户账户存在未经授权的登录尝试,诱导受害者配合安全验证。

  • 发送钓鱼邮件

诈骗者发送伪造的 Coinbase 邮件,包含假冒的案例编号(Case ID)。

  • 引导用户转账

诈骗者要求受害者将资金转入 Coinbase Wallet,并将诈骗地址列入白名单,声称这是一种账户安全验证方式。

  • 克隆 Coinbase 网站

诈骗者创建几乎 1: 1 复制的 Coinbase 钓鱼网站,并通过伪造邮件和 Telegram 诈骗面板向受害者发送不同的操作提示。

除此之外,据 Cointelegraph 报道,近期多个加密货币用户还收到了冒充 Coinbase 和 Gemini 的诈骗邮件。这类邮件通常声称因监管要求,用户必须过渡到自托管钱包,并设定 4 月 1 日 为最后期限,以制造紧迫感。

邮件内提供了下载 Coinbase Wallet 或 Gemini Wallet 的链接,并附上预生成的恢复短语。一旦用户使用这些短语创建新钱包并转移资产,资金便会被诈骗者瞬间清空。

内部数据访问问题浮出水面

社交工程诈骗的核心在于精准的信息获取,而在 Coinbase 用户被骗案件中,攻击者似乎掌握了受害者的个人信息,包括电话、电子邮件地址、交易记录等。这引发了一个关键问题:这些数据究竟是如何落入诈骗分子手中的?

昨日,The Block 联合创始人 Mike Dudas 在 X 平台称自己收到了来自 Coinbase 的一封邮件。这封邮件内容令人不安,直指内部数据访问问题。邮件中写道:

“我们写信通知您,我们检测到有迹象表明,一名 Coinbase 员工可能以不符合内部政策的方式,查看了少量 Coinbase 客户的账户记录,其中包括您的账户。”

虽然邮件中称,“您的资产仍然安全,您的 Coinbase 账户未遭到破坏”,并且强调目前没有证据表明数据泄露至外部,但这封邮件却给用户发出了一个明确的警告:内部数据的访问问题已经被确认,且并非孤立事件。

Dudas 表示,这解释了那些假冒 Coinbase 发送的钓鱼邮件和电话。

然而,数据泄露范围存疑,或涉及更广泛的用户。社区用户 @ghaiankur 表示:“我在 Coinbase 上没有任何资金,而且从未使用过。但我还是因为有账户而收到了这些邮件,这可能不仅仅是针对几个目标账户,而是整个数据库。”

数据泄露成行业隐患

不仅是 Coinbase,其他交易所似乎也面临着类似的内部安全隐患。

Dudas 分享邮件后,加密交易员 Jordan Fish(@Cobie)爆料称,加密交易所 Kraken 也最近遭遇了类似攻击。他推测:“这可能是攻击者的策略——渗透客服团队,从内部窃取用户数据。”

与此同时, 3 月 27 日,暗网新闻网站 Dark Web Informer 披露,一名代号为 AKM 69 的黑客声称,掌握了加密交易所 Gemini 大量用户的私人信息。该数据库包含 100, 000 条记录,其中涉及美国用户的全名、电子邮件、电话号码和位置信息,甚至还包括一些新加坡和英国用户的数据。

要么学会保护用户,要么被用户抛弃。

Solana 联合创始人 toly 在评论此事件时表示,交易所应当实施用户可控的转账时间锁(time lock),以降低资产被迅速盗取的风险。然而,这次事件的本质远不止于此,而是暴露了交易所内部风控失效,以及诈骗行为的高度产业化。

交易所的安全,早已不仅仅是技术防护的问题,更是管理与信任的问题。 在日益复杂的攻击手段下,如何建立更完善的风控体系,将决定未来行业的安全基准。

Stablecoins Are the 'Royalists' of the Crypto World: Open USD Brings the Old Monetary System into the Fray

Title: Stablecoins Are the "Royalists" of the Crypto World: Open USD Brings the Old Monetary System into the Fray The article analyzes the launch of Open USD, a new dollar-pegged stablecoin backed by a coalition of over 140 traditional financial, payment, and tech giants like Visa, BlackRock, and Google. Author Hu Yilin argues that stablecoins like Open USD represent not a "moderate" wing of the crypto revolution, but a "royalist reform" within the old monetary system. He posits that while stablecoins adopt blockchain's efficiency, programmability, and borderless nature, they fundamentally reinforce the US dollar's centrality and the Federal Reserve's authority. They aim to replace inefficient "bureaucrats" (like traditional payment networks) rather than challenge the "monarch" (the dollar-based system). Thus, Open USD symbolizes the old system co-opting blockchain technology to upgrade dollar hegemony, potentially marginalizing native crypto projects like Circle's USDC. Hu contrasts this with more revolutionary paths, like a "Bitcoin standard," which seeks to change the monetary base itself. He warns that if the crypto ecosystem's unit of account, collateral, and value anchor remain dollar-denominated stablecoins,链上繁荣 may enrich the traditional financial system ("off-chain") rather than granting monetary premium to native crypto assets like ETH. Projects with civilizational ambitions, he argues, cannot reduce their narrative to mere "fuel" or transaction fees but must grapple with the core revolutionary idea: that a decentralized market does not require a central bank as the anchor of monetary order.

Standard Chartered Takes Over USDC Onboarding; Circle Cedes Control for Scale

Standard Chartered and Circle have announced a partnership where institutional clients can now mint and redeem USDC directly through Standard Chartered's existing banking infrastructure, eliminating the need for separate accounts with Circle. Initially launching in the Dubai International Financial Centre (DIFC), this service represents the first time a Global Systemically Important Bank (G-SIB) is offering such direct, integrated access. This move effectively "translates" USDC into a standard banking option, opening the door for major institutional capital like pension funds and sovereign wealth funds that require the trust, compliance, and risk frameworks of a major bank. For Circle, this is a strategic trade: ceding some direct client relationships to leverage Standard Chartered's vast distribution network, thereby potentially massively scaling USDC's circulation and its core interest revenue model. For Standard Chartered, it's a chance to offer a new digital asset service without building the underlying stablecoin infrastructure. The partnership signals a significant shift in the stablecoin narrative. Rather than bypassing traditional finance, stablecoins are becoming integrated into it, with major banks like Standard Chartered positioning themselves at the crucial entry point. The focus is moving from legitimizing stablecoins to determining how value and pricing power will be distributed among issuers, banking channels, and regulatory frameworks in this new, converging landscape.
