Trezor 在 Coldcard 遭遇 1 亿美元钱包被盗后提升密码防护上限

Trezor 将可选钱包密码短语长度上限提升至 128 位

硬件钱包制造商 Trezor 宣布,将其可选钱包密码短语(passphrase)的最大长度从 50 个字符增加至 128 个字符。Trezor 表示,这一变更已在其 Trezor Suite 软件及更新的设备固件中生效。需要注意的是,使用旧版固件的用户仍受限于 50 个字符的长度限制。

增强安全性:双重防护机制

据 Trezor 介绍,密码短语的作用类似于额外的密码,用户需将其与钱包的助记词(恢复短语)配合设置。即使攻击者获取了助记词,若无法提供正确的密码短语,仍然无法访问该钱包中的资金。

Trezor 引用了今年七月发生的 Coldcard 事件作为背景:当时由于固件缺陷,部分设备生成的助记词随机性不足,导致攻击者能够重建这些短语。Trezor 指出,正是凭借强大且独特的密码短语,部分受影响用户成功保护了自己的资产。

安全警示:建议检查购买渠道

此次更新紧随另一项涉及 Trezor 自身设备的安全警告之后。本周五,该公司建议自三月起从前授权经销商 CryptoBilis 处购买钱包的客户,将资金转移至新的钱包地址。

此前,一名印尼客户报告称,其持有的 Trezor Safe 5 设备内部疑似被植入恶意装置,该装置可能捕获屏幕信息(包括助记词),并通过蜂窝网络进行传输。Trezor 方面在本周五回应称,尚未对该设备进行检验,也未收到相关损失报告。
