背景概述

近期 Web3 项目方/名人的 X 账号被盗并被用于发送钓鱼推文的事件频发,黑客善于利用各种手段盗取用户账号,较为常见的套路如下:

  • 诱导用户点击假冒的 Calendly/Kakao 会议预约链接,从而窃取用户账号的授权或控制用户的设备;

  • 私信诱骗用户下载带木马的程序(假冒游戏、会议程序等),木马除了会盗取私钥/助记词之外,可能还会窃取 X 账号权限;

  • 利用 SIM Swap 攻击,窃取依赖手机号的 X 账号权限。

慢雾安全团队协助解决了多起类似事件,如 7 月 20 日,TinTinLand 项目方 X 账号被盗,攻击者置顶了一条含有钓鱼链接的推文。在慢雾安全团队的协助下,TinTinLand 及时解决了账号被盗问题,并对 X 账号进行了授权审查和安全加固。

查看授权过的应用

很多钓鱼方式是利用用户误点击授权应用链接,导致把 X 账号的发推权限授权出去,随后账号被用于发送钓鱼信息。

排查方法:选择“Apps and sessions”栏目,查看账号授权给了哪些应用,如下图,演示账号授权给了这 3 个应用。

查看异常登录日

如果用户怀疑账号被恶意登录,可以通过排查登录日志来查看异常登录的设备,日期和地点。

排查方法:Settings → Security and account access → Apps and sessions → Account access history

The Full Story of How Crypto Unicorn Blockstream Is Mired in Serious Fraud Allegations

This article details serious allegations of fraud against Bitcoin infrastructure company Blockstream, founded by Bitcoin pioneer Adam Back. In June 2024, investigative account NatInfoSec published a report accusing Blockstream's mining note (BMN) program of potentially operating a multi-billion dollar scheme with Ponzi-like characteristics. The core allegations focus on Blockstream Mining Notes (BMNs), which offer investors fixed annual yields up to approximately 20% from Bitcoin mining. NatInfoSec's investigation raises several key issues: 1. **Suspicious Hashrate & Payout Capacity**: The analysis suggests Blockstream would need 20-45 EH/s of mining power to cover its BMN obligations, but its public dashboard shows only around 15 EH/s. Furthermore, no verifiable public evidence (e.g., grid connection records, import data) was found to support the massive mining operation required. 2. **Questionable Payout Source**: The BMN contract allows Blockstream to use Bitcoin from *any source* (Substitute Performance BTC) to fulfill investor payouts, raising concerns that payouts may not come from actual mining revenue. 3. **High-Risk, Fixed Returns**: Offering ~20% fixed yields in the volatile, cyclical Bitcoin mining industry is viewed as highly unusual and requires clear explanation. 4. **Undisclosed Criminal Record of Key Figure**: Christopher William Cook, a key figure in Blockstream's mining operations and CEO of spin-off Exacore, was found to have a federal felony conviction for mail fraud in 2008, a fact not disclosed in BMN offering documents. His background was also allegedly embellished. 5. **Potential Contagion to BSTR SPAC**: Questions were raised about whether these liabilities and Cook's record should have been disclosed in the SEC filings for Bitcoin Standard Treasury Company (BSTR), a separate Adam Back-associated firm planning a SPAC merger. The crypto community is divided. BitMEX Research validated Cook's criminal record and expressed concern over the high yields but found other evidence lacking or misleading, noting the legal separation between BMN, Blockstream, and BSTR. Blockstream defenders, like Samson Mow, argue the mining is real. Critics, however, emphasize the lack of independent, verifiable proof of the mining operation's scale and the true source of investor payouts. The article concludes that BMN remains shrouded in key unanswered questions regarding its actual size, the verifiability of its underlying mining assets and payouts, the source of its high yields, and the full role and disclosure concerning Chris Cook. Blockstream had not issued a comprehensive response at the time of writing.
