上周发生一起黑客攻击事件,比特浏览器的许多用户于社群反应其私钥被盗,有猜测称该情况因使用比特指纹浏览器所致,开启了扩展数据同步的用户钱包有被盗风险,建议立即采取措施,转走钱包资产。比特浏览器是一款多账户管理工具,允许用户轻易建立多个 IP 的浏览器视窗分页。
目前单一用户最高被盗资产高达 6 万美金,并有超过 3,000 个钱包遭到资产损失,总损失高达 41 万美元。比特浏览器官方表示目前比特服务端缓存数据遭到黑客入侵导致用户的私钥外泄和资产被不法转移,已经报案,并联系 MetaMask 冻结黑客钱包。然而,由于缺乏透明度和即时的危机处理,部分用户对其采取的措施表示质疑和不信任。
而根据昨日 8/29 最新消息,慢雾首席信息安全官 23pds 在推特上表示:“关于比特浏览器大量用户被盗的情况,目前我们已经联合合作伙伴成功拦截了一部分在洗的资金。比特浏览器正在立案,立案成功慢雾会正式介入。”
指纹浏览器与空投猎人
对于空投猎人来说,如何防止多账号关联一直是重点研究的一件事,除了最基础的隔离链上地址之间的关联外,IP 隔离也是很多人在意的点,而指纹浏览器便是为了这需求诞生的产品。指纹浏览器可以模拟不同的浏览器指纹,防止账号关联和被封禁,这对于多账户操作如跨境电商、社交媒体、广告投放等业务来说相当有用。
浏览器与钱包安全问题
但同时需要注意的是,无论是比特浏览器还是其他第三方修改的浏览器,或是其他类似的多账户管理工具,用户都需要高度警觉以下几个安全问题:

  • 浏览器或插件本身的安全性:由于此类型为了特殊需求衍生的浏览器大多在 Chrome 核心基础上修改,但在版本更新上可能因此会无法第一时间便更新至最新版本,以至于黑客能利用和新版本与第三方版本不同步的更新时差,在这段时间内找出漏洞攻击。因此,用户应选择信誉良好和安全性高的工具,并定期更新到最新版本。
  • 用户自身的操作安全:私钥管理是大多是加密货币使用第一堂便需要学习的课程,但久而久之有许多用户因为被黑这件事自己从未遇过便忽视了其重要性,私钥是必须备份且绝对不建议联网储存的或与他人分享的,尽管许多平台皆保证皆会加密处理,但将自己财务风险暴露在其他人的软件上,仍不是个明智之举。
  • 与第三方服务的互动:在链上与 Dapps 互动时需特别注意,是否为官方管道避免被仿冒的钓鱼网站骗走资产,而在与新协议互动式需要花费更多的时间来确保此项目是否有人背书或是团队是否正规,切勿一股脑上头便急忙的操作。


笔者观点
这次比特浏览器的黑客攻击事件是一个警钟,提醒所有涉足加密货币的个人和机构,特别是管理众多帐户地址的空投猎人或工作室,必须更加严格地注意自己的资讯安全和私钥管理,在这类型的第三方服务器下最好是使用无私钥的 AA 钱包,或是使用 wallet connect / coinbase wallet 等利用手机扫码操作的钱包,避免私钥直接曝露在第三方公司运营的平台上。
从比特浏览器官方的回应便可以知晓其团队对于区块链安全的了解有待提高,竟表示联系 MetaMask 冻结黑客钱包令人啼笑皆非。当资料泄漏一事发生在其他 Web2 使用者占多数的平台可能后果不是如此巨大,但当你的使用者大多是 Web3 用户时便不是这么一回事了。而对于用户来说只有建立全面的安全机制和紧急应对计划,才能在这个高风险但高报酬的领域中长期生存,毕竟为了空投奖励而损失本金便有些本末倒置了。

Bitcoin Is Ready for "Parabolic Growth". Is Altseason Upon Us?

Amid a general market uptrend, experts are discussing the potential start of an 'altcoin season', where major cryptocurrencies could outpace Bitcoin's growth. This follows Bitcoin surpassing $81,000, predictions of a new bull market, and a capital shift from AI stocks toward Bitcoin and gold. Since August 17th, the crypto market has risen over 22%, primarily driven by Bitcoin (BTC) and Ethereum (ETH), which gained 25% and 30% respectively, reaching highs last seen in May. Analysts suggest the Bitcoin bear cycle has ended, anticipating a historically strong rally, with renewed institutional demand for cryptocurrency ETFs. BitMEX founder Arthur Hayes, in a recent interview, declared the start of a new bull market, predicting Bitcoin could quickly reach "hundreds of thousands" of dollars. Market observers interpret this as an expectation for 'parabolic growth.' Signs of a bull market revival include Bitcoin ETFs re-entering the top 10 most-traded ETFs, displacing some AI-focused funds. Analysts at CryptoQuant note capital is flowing from Bitcoin into riskier altcoins, with their bull market indicators showing the most optimistic signals since October 2025. However, the reality is more nuanced. The current surge is a rebound from yearly lows; Bitcoin's price is still down nearly 40% from its October peak. The Altcoin Season Index has dropped to 39 from 67 in early August, and Bitcoin's dominance remains around 60%, indicating investor focus is still on Bitcoin rather than altcoins. Experts predict the market is entering a phase where project fundamentals and real revenue, rather than speculation, will increasingly determine asset value.

$120 Million Vanishes Overnight! Crypto's 'Steadiest Giant' Stumbles in South America

Summary: Tether's $120 million Bitcoin mining venture in Uruguay, initiated in May 2023, was abruptly shut down in July 2025 when the national power utility UTE cut off electricity. The project, developed in partnership with local firm Microfin in Florida province, was touted as a model for leveraging the country's nearly 98% renewable energy grid. The collapse stemmed from a fundamental contract dispute over electricity supply. Tether interpreted the agreed power volume as a "minimum guaranteed supply," expecting to request more as the mining operation expanded. UTE, however, viewed it as a "strict maximum cap." This disagreement led to frequent power curtailments for the 24/7 mining facility, causing significant revenue loss from lost computing power. Following the 2025 election of left-wing President Yamandú Orsi and a management change at UTE, negotiations broke down. Microfin stopped paying electricity bills in May 2025, formally notified UTE of contract termination in June, and did not attend a final meeting where UTE presented a revised contract. By the July 25 power cut, Microfin's debt approached $5 million. The operation ceased, laying off 30 of its 38 local staff, with all outstanding debts settled by December 2025. The failure highlights key risks for heavy-asset overseas investments: Uruguay's green energy proved not to be cheap energy, especially after the 2024 Bitcoin halving squeezed industry profits. Furthermore, political changes can swiftly alter utility company policies, undermining the long-term regulatory stability critical for such projects. While financially absorbable for Tether, the incident underscores that operational success depends on unambiguous contracts and genuine cost advantages, not just technological scale.

Is Bitcoin Price Lagging? Record Global M2 Money Supply Could Be a Springboard for BTC's Rise

Bitcoin Price Lagging? Record Global Money Supply M2 Could Springboard BTC Growth The global money supply (M2) is expanding rapidly, similar to global debt. The US M2, representing all money circulating in its economy, has reached a record $23.16 trillion. Combined with figures from major economies like the Eurozone, China, and Japan, the global M2 is approximately $103 trillion. Some estimates, however, place it closer to $195 trillion. This surge in liquidity is significant because excess capital often seeks higher returns in assets like precious metals, stocks, and cryptocurrencies. Bitcoin's recent price surge above $81,000 has brought the global M2 metric back into focus. Following a sharp rise in early August after a US Treasury bond buyback announcement, BTC still trades about 37% below its October 2025 all-time high exceeding $126,000. This gap presents a potential "catch-up" trade thesis. Bitcoin's fixed supply of 21 million contrasts with governments' ability to print fiat currency, making scarce assets like BTC attractive if monetary expansion continues. Historically, Bitcoin's bull cycles in 2017-2018 and 2020-2021 coincided with M2 expansion and increased liquidity. Over the past year, the correlation seemed broken as M2 grew while Bitcoin's price fell sharply from its peak. Observers believe fresh dollars may have remained locked in cash-favorable investments. Some, like Ash Crypto, now suggest a long-awaited alignment between Bitcoin and M2 may be starting, especially as a weakening US Dollar Index this month has seen assets like gold and Bitcoin surge. A softer dollar pressures cash havens and prompts holders to act. While record M2 doesn't guarantee higher Bitcoin prices, a sustained influx of liquidity, a weak dollar, and capital flowing into alternative assets could trigger a catch-up rally sooner than expected. However, changes in these conditions could lead to the opposite outcome.
