已经过去了 18 天,从 7月30日 开始的 Coldcard 漏洞利用的影响仍在持续。Galaxy Research 在 8月16日 与 200 多名受害者进行了交谈,以了解攻击背后的情报。 

被盗的代币是在存在漏洞的 Coldcard 固件发布的当天产生的。这发生在 2021年3月17日,当时 Bitcoin [BTC] 的区块高度已达到 674,951。这一时机使得此次攻击值得关注,因为它还将该漏洞利用与助记词生成缺陷联系起来。

在这类缺陷中,不法分子通常会预测或伪造被盗钱包的助记词熵。

损失评估

在这里,值得注意的是,2021 和 2022 之间的时期是被盗地址最集中的时期。

此外,在 Galaxy 公布的盗窃数据集中的 8,680 个地址中,只有一小部分与报告损失的受害者直接相关。尽管这些地址持有大约 1,778.6 BTC

此外,所有 192 名个人报告的损失都涉及公开数据集中的地址,其中包括大约 1,790 个地址和 714.8 Bitcoin。

AMBCrypto 最近报道,这些损失在约 7,300 个地址中超过了 1,596 BTC,价值超过 $100 million。不过,考虑到 8月16日 的 Bitcoin 价格,总损失目前已超过 $115 million。

我们对攻击者了解多少?

调查过程中发现了一些“指纹”。这些指纹基于交易行为,如区块时间、手续费、锁定时间、RBF/序列设置、交易结构和目标地址。

Why this matters

The reported losses and years-long concentration of affected addresses suggest a potentially material seed-generation weakness rather than an isolated wallet compromise. The incident could undermine confidence in hardware-wallet entropy generation and highlights the need for users and vendors to assess whether affected wallet seeds require migration.

例如,Wave 1 从区块 960,183–960,191 中盗取了大约 1,082.65 BTC。他们通常在每笔交易中将一名受害者的资金转移到四个归集地址中。

来源:Galaxy Research

同样,Wave 3 处理了 63 名受害者,Wave 2 处理了 19 名,而 Footprint E 每笔交易批量处理多达 795 名受害者,中位数为 118。

目标模式也各不相同,一些团体将资金分散到数百个地点,而另一些团体则将其集中到少数几个地址中。


最终总结

  • 漏洞利用影响了 192 名个人,约 714.8 Bitcoin 被盗。
  • 这些重大损失大多发生在 2021 和 2022 之间。
