SlowMist 发现了一个广泛使用的加密库中的一个严重的安全漏洞，这可能允许黑客对依赖于它的应用程序中的私钥进行逆向工程。 区块链安全公司 SlowMist 标记了 JavaScript 椭圆加密库中的一个严重安全漏洞，该库通常用于加密钱包（包括 MetaMask、Trust Wallet、Ledger 和 Trezor）、身份验证系统和 Web3 应用程序。具体来说，标记的漏洞允许攻击者通过在单个签名操作期间操纵特定输入来提取私钥，这可以让他们完全控制受害者的数字资产或身份凭证。 ⚠️在广泛使用的椭圆加密库中发现了一个严重漏洞（GHSA-vjh7-7g9h-fjfh）。😈攻击者可以通过制作特定输入来利用此漏洞，仅使用一个签名即可提取私钥，从而可能危及数字资产或……— SlowMist (@SlowMist_Team) 2025 年 3 月 5 日 典型的椭圆曲线数字签名算法过程需要几个参数来生成数字签名：消息、私钥和唯一的随机数 (k)。消息被散列，然后使用私钥进行签名。至于随机值 k，需要确保即使同一条消息被多次签名，每个签名都是不同的——类似于邮票每次使用都需要新墨水。SlowMist 发现的特定漏洞发生在 k 被错误地重复用于不同的消息时。如果重复使用 k，攻击者可以利用此漏洞，从而可以对私钥进行逆向工程。 你可能还喜欢：新闻 卡巴斯基警告 SparkCat 恶意软件针对 Android 和 iOS 上的私钥 ECDSA 中的类似漏洞在过去曾导致过安全漏洞。例如，2021 年 7 月，攻击者利用弱 ECDSA 签名攻击了 Anyswap 协议。他们利用该漏洞伪造签名，从而从 Anyswap 协议中提取资金，导致损失约 800 万美元。 你可能还喜欢：无需私钥或种子短语即可恢复加密钱包 | 观点

加密货币恐惧与贪婪指数已暴跌至 25，较前一天下跌 19 个点，并将市场推入“极度恐惧”区域。 此次大幅下跌是在美国总统唐纳德·特朗普于 4 月 2 日宣布新的激进“解放日”关税之后发生的，此举扰乱了传统市场和加密货币市场。特朗普的政策对进口产品设定了 10% 的基准关税，对特定国家的税率则要高得多。 中国现在要缴纳 54% 的关税，这是新税率 34% 与现有 20% 关税的结合。欧盟将征收 20% 的关税，而越南（46%）、台湾（32%）、印度（26%）和日本（24%）也将受到税率上调的影响。 不过，加拿大和墨西哥目前免于 10% 的基准关税和额外的互惠税。只有特朗普取消目前对这些国家征收的 25% 关税后，才会征收 10% 的关税，这些关税最初是出于对贩毒和犯罪的担忧而实施的。 你可能还喜欢：富达为美国投资者推出免费加密 IRA 特朗普还对所有在其他国家生产的汽车征收 25% 的关税，该措施将于 4 月 4 日午夜生效。尽管投资者对此表示怀疑，但他声称该措施将保护美国产业并降低消费者价格。 特朗普宣布加征关税后，美国股市暴跌，道琼斯期货下跌逾 1,000 点，标准普尔 500 指数和纳斯达克指数大幅下跌。加密货币市场也紧随其后。根据 crypto.news 价格追踪器，加密货币市值缩水 4% 至 2.7 万亿美元。 特朗普上台后，比特币（BTC）最初飙升至 88,500 美元，但很快跌至 83,073 美元，在过去 24 小时内下跌了 2%。其他主要加密货币也出现下跌。以太坊（ETH）下跌 4% 至 1,816 美元，而 Solana（SOL）下跌 5.2% 至 119 美元。根据 Coinglass 的数据，抛售引发了 24 次清算，共计 5.14 亿美元，其中 2.9 亿美元来自多头仓位。 BitMEX 加密货币交易所联合创始人 Arthur Hayes 通过 X 指出，尽管市场对“解放日”关税做出了负面反应，但如果比特币在 4 月 15 日美国纳税日之前保持在 76,500 美元以上，市场将“走出困境”。他警告投资者不要“被砍掉”。 阅读更多：CME 将为散户投资者推出 BTC、ETH 现货报价期货

The chain is EVM-compatible and now supports native USDC via Circle’s Cross-Chain Transfer Protocol V2, integrated on Apr. 15.

This breakout is supported by rising volume. At 61, the relative strength index is bullish but still below overbought levels. This suggests there may still be room for the rally to continue. Sonic price analysis. Credit: crypto.news If the price maintains above $0.57 and the volume stays high, the next significant resistance level is $0.60. A clear breakout above that might lead to $0.68. Sonic may revert to its previous range of $0.45–$0.50 if the breakout fails and the price falls below the 50-day moving average at about $0.50. Looking ahead, Sonic Labs will host the Sonic Summit from May 6–8 in Vienna, Austria, with participants including Trust Wallet. Anticipation of major announcements at the event could sustain bullish momentum for the S token. Read more:Sonic debuts Mobius mainnet, first chain extension on Solana
