Coldcard 盗币事件新进展，第一波攻击者身份或已被 FBI 掌握

ChainCatcher 消息，据 Bitcoin Magazine 报道，2026 年 7 月 Coldcard 硬件钱包大规模盗币事件调查取得进展。第一波攻击中约 1082.65 枚 BTC（约 1.18 亿美元）仍存放在攻击者地址中，调查发现攻击者使用了某区块链数据服务商的付费账户，内部日志与盗币模式“高度吻合”，相关线索已移交执法部门。Galaxy Research 分析师 Alex Thorn 表示，第一波攻击者身份“可能已被执法部门掌握”。后续几波攻击合计约 2000 枚 BTC 被盗，其中第二波约 76 枚 BTC，操作模式与第一波相似，可能为同一行为人。事件源于 Coinkite 在 2021 年 3 月的代码更新中引入的熵生成漏洞，导致部分使用 MK2 及后续型号、固件 4.1 及以上版本的设备生成了低强度私钥，种子可被暴力破解。Coinkite 已发布修复固件并建议用户迁移资产，但漏洞影响范围仍在评估中。
