公共Wi-Fi与一通电话,如何成为盗走5000美元加密资产的完美陷阱?

Abstract

作者在酒店度假期间连接公共Wi-Fi后,加密钱包被盗5000美元。攻击者通过监听其加密货币相关电话对话锁定目标,利用酒店Wi-Fi的中间人攻击注入恶意代码。当用户在Jupiter交易所操作时,恶意代码诱骗其签署了授权许可而非直接转账交易,导致攻击者获得资金操作权限。数天后资产被转移。作者反思三个错误:使用公共Wi-Fi而非手机热点、在公共场合讨论加密资产、未仔细审查钱包授权请求。建议用户始终保持警惕,即使在使用信任的应用时也需认真核对交易详情。

原标题:连了三天酒店 Wi-Fi,加密钱包被盗了 5000 美金


几天前,我和家人一起去一家非常不错的酒店度过年末假期。在离开酒店一天后,我的钱包却被完全掏空了。我百思不得其解,因为我既没有点击过任何钓鱼链接,也没有签署过任何恶意交易。

经过数小时的调查,并请来专家帮忙后,我终于弄明白了事情的真相。这一切竟然是因为酒店的 Wi-Fi 网络、一通简短的电话,以及一连串愚蠢的错误。

和大多数加密货币爱好者一样,我随身带着笔记本电脑,想着在陪家人度假时还能抽空工作一下。我的妻子一再坚持让我在这三天里不要工作,我真应该听她的话。

和其他住客一样,我连接了酒店的 Wi-Fi 网络。这个网络不需要密码,只需通过一个验证页面(captive portal)即可登录。

我像往常一样在酒店里工作,没有做任何冒险的操作:没有创建新钱包,没有点击奇怪的链接,也没有访问可疑的去中心化应用(dApps)。我只是查看了一下 X(推特)、我的余额、Discord 和 Telegram 等。

某一刻,我接到了一个加密圈朋友的电话,我们聊了聊市场行情、比特币以及加密货币的相关话题。但我不知道的是,附近有人在偷听我们的对话,并意识到我在从事加密货币相关的事情。这是我的第一个错误。对方通过我们的对话了解到我在使用 Phantom 钱包,而且我是一个持有量不小的用户。

这让他将目标锁定在了我身上。

在公共 Wi-Fi 网络中,所有设备都共享同一个网络,实际上设备之间的可见性比你想象的还要高。用户之间几乎没有真正的保护措施,这就为“中间人攻击”(Man-in-the-Middle Attack)提供了可乘之机。攻击者就像一个中间人,悄悄地插入在你和互联网之间,就像有人在你的信件送达之前偷偷阅读并篡改内容。

当我在酒店 Wi-Fi 上浏览网页时,有一个网站看起来正常加载,但实际上页面背后被注入了额外的恶意代码。我当时并没有注意到任何异常。如果我安装了一些安全工具,本可以发现这些问题,但遗憾的是,我并没有。

通常情况下,网站可能会请求你的钱包签署某些操作。Phantom 钱包会弹出一个窗口,你可以选择批准或拒绝。一般来说,你会因为信任这个网站和浏览器而放心签署。然而,那天我不该这么做。

就在我在 @JupiterExchange 平台上进行代币兑换操作时,恶意代码触发了一个钱包请求,取代了我正常的兑换操作。我本可以通过仔细检查交易详情发现这是一个恶意请求,但因为我已经在 Jupiter 平台进行兑换操作了,所以完全没有起疑心。

那天我并没有签署任何转移资金的交易,而是签署了一个授权许可。这正是几天后资产被盗的原因。

恶意代码并没有直接要求我发送 SOL(Solana),因为那样会太明显。取而代之,它请求我“授权访问”、“批准账户”或“确认会话”。用简单的话说,我实际上是给了另一个地址代我操作的权限。

我之所以批准了,是因为我误以为这与我在 Jupiter 的操作有关。当时 Phantom 钱包弹出的信息看起来很技术化,没有显示任何金额,也没有提示立即转账。

而这正是攻击者所需要的一切。他耐心等待,直到我离开酒店后,才开始行动。他将我的 SOL 转走,提取我的代币,并将我的 NFT 转移到另一个地址。

我从未想过这样的事情会发生在我身上。幸运的是,这并不是我的主钱包,而是一个用于特定操作的热钱包,并非用来长期持有资产的。但即便如此,我还是犯了很多错误,而我认为自己对此负有主要责任。

首先,我绝不应该连接酒店的公共 Wi-Fi。我本该用手机的热点来上网才对。

我的第二个错误是,在酒店的公共区域里谈论加密货币,让许多人可能听到了我们的对话。我父亲曾经告诫我,永远不要让别人知道你从事加密货币相关的事情。这次还算幸运,有些人因为加密资产甚至遭遇绑架或更糟糕的事情。

另一个错误是,我在没有完全注意的情况下批准了钱包请求。因为我确信这个请求来自 Jupiter,我没有仔细分析它。事实上,每一次钱包请求都应该被认真审查,即使是在你信任的应用程序上。请求可能会被拦截,实际上并非来自你以为的应用。

最终,我从一个次要钱包里损失了大约 5000 美元。虽然这还不算最严重的情况,但依然让人感到非常沮丧。

In Conversation with Ray Dalio: We Are Currently in an AI Bubble, with 1% of My Portfolio in Bitcoin

Ray Dalio, founder of Bridgewater Associates, warns in an interview that the current AI boom shows classic bubble characteristics, which could lead to significant economic downturns as seen in past cycles like 1929 or 2000. He explains that speculative enthusiasm, fueled by debt and overvaluation, often precedes a crash when rising rates or taxation force asset sales, causing widespread losses and recession. Dalio also outlines his "Big Cycle" theory, describing an approximate 80-year pattern where widening wealth gaps, massive government deficits, and shifting geopolitical power (like China's rise) create internal conflict and global instability. He emphasizes that we are in a late-cycle, transitional phase where traditional powers like the US and UK face decline. For personal wealth protection, Dalio advises diversification beyond cash into assets like stocks, bonds, real estate, and particularly gold, which he prefers over Bitcoin. While he holds about 1% of his portfolio in Bitcoin as a non-printable hard asset, he views gold as more secure from technological or governmental threats. Regarding AI's impact, Dalio believes it will disproportionately benefit capital owners, worsening inequality by replacing both physical and cognitive labor. He suggests that human intuition and emotional intelligence, combined with AI, will be key for future workers. On taxation, Dalio argues that wealth taxes are impractical and risk triggering asset sell-offs, reducing productive investment. He points to the UK as a cautionary example of debt, low productivity, and political strife. Geopolitically, Dalio foresees a more regionalized world, with the US showing weakness in prolonged conflicts like with Iran, akin to past imperial declines. The ideal outcome, he suggests, is coexisting powerful blocs (e.g., Americas, China-Asia Pacific) without major war.

Daily 7.2 Trillion KRW: Foreign Capital's Record Net Buying on Friday! Wall Street Says Headwinds for Korean Stock Fund Flows Have Subsided

South Korean stock market sees a dramatic shift in fund flows. On July 31, foreign investors made a record net purchase of approximately KRW 7.2 trillion in KOSPI stocks, marking a fundamental reversal from the persistent large-scale net outflows seen in previous months. This contributed to a significant narrowing of foreign net selling in July to KRW 9.8 trillion, down sharply from KRW 48.4 trillion in June and KRW 44.5 trillion in May. Simultaneously, domestic institutional pressure eased. South Korean pension funds and asset managers turned to a net buying position in July, purchasing KRW 1.0 trillion worth of KOSPI shares, contrasting with net sales in May and June. Market volatility is expected to be dampened by new financial regulations. Effective July 31, the Financial Services Commission tightened access for retail investors to single-stock leveraged ETFs by raising the minimum cash deposit requirement. Trading volumes for these products subsequently dropped to about 50% of their monthly average. Citigroup Research maintains its year-end KOSPI target of 10,000 points. The firm cites several supportive factors: the substantial easing of headwinds from capital outflows, a robust fundamental outlook for the semiconductor sector, historically low market valuations, strong economic fundamentals, and the potential for policy support from financial authorities if needed.

Thanks to Dice Rolls, Bitcoin Keys Are Stored Offline, But Not Everyone Will Do It

The article discusses using dice rolls to generate secure Bitcoin wallet seeds, providing entropy independent of potentially flawed hardware random number generators. It explains that each fair dice roll offers about 2.585 bits of entropy, with around 50 rolls needed for a standard 12-word seed phrase and 99+ recommended for higher security. This method gained attention after a vulnerability was revealed in some Coldcard hardware wallets, where a faulty firmware RNG (dating back to 2021) compromised generated keys. The analysis notes that while a dice-generated main seed was safe from this specific flaw, other Coldcard functions (like creating paper wallets, backup keys, or passwords) could still be vulnerable if they used the defective RNG. The piece argues that while dice-based entropy is technically robust, the manual process is error-prone, tedious, and unrealistic for most new users, who might make mistakes in recording or inputting rolls. It concludes that while manual entropy generation should remain an option for advanced users, the long-term goal is to develop reliable, user-friendly hardware and software that securely generates randomness without requiring specialized knowledge. Coldcard users are advised to check their firmware version and replace any secondary secrets (like paper wallet keys) created with vulnerable devices, while also considering multi-signature setups with devices from different manufacturers for added security.
