BTC Ledger discovers malicious hardware in tampered wallets sold by CryptoBilis
Ledger, a leading provider of cryptocurrency hardware wallets, reported that traces of unauthorized hardware modifications were found in a device related to a recent security incident. The company discovered an illegal component inside wallets purchased by its users through authorized Southeast Asian distributor CryptoBilis.
Hardware tampering raises security concerns
For the first time in this case, this investigation has revealed physical evidence that at least one Ledger device was tampered with before reaching customers. The modified device contained an external hardware implant, raising concerns about the potential exposure of user funds and the scope of the spread of infected wallets.
Currently, the specific functions and impact of the implant are unclear, and Ledger has not yet determined the number of wallets that may be affected. However, the company has confirmed that it is working with law enforcement agencies and contacting users who may have been affected by the incident.
Ledger said in its latest statement that it discovered illegal hardware inside user devices related to the CryptoBilis security incident and is actively cooperating with law enforcement and affected users.
According to Ledger, an attacker may not need to have direct access to the secure element responsible for generating and protecting a user's private key. Instead, unauthorized hardware components appear to be designed to intercept and monitor communication lines inside the device, potentially revealing sensitive information displayed on the wallet screen.
作为预防措施，CryptoBilis 已暂停所有硬件钱包的销售，直至调查结束。
迷你词典：CryptoBilis
CryptoBilis 是一家位于东南亚的 Ledger 硬件钱包授权分销商，负责零售用于离线存储加密货币的安全设备。
Mark Karpelès 发起独立调查
前 Mt. Gox（一家倒闭的比特币交易所）首席执行官 Mark Karpelès 也在独立调查此案。利用受影响用户提供的照片，Karpelès 证实了此前关于疑似被篡改的 Ledger 钱包中发现异常组件的报道。
Karpelès 通过社交媒体呼吁拥有可疑设备的个人捐赠这些设备以进行进一步的技术分析。他透露，他曾亲自拆解并检查其中一个植入物，希望更好地了解其结构和运作方式。
Karpelès 评论道：“拆解加密货币钱包中的间谍植入物可能是我今年做过的最赛博朋克的事情。”这反映了他所发现事物的非同寻常性质。
在此前的更新中，Karpelès 报告称在一台来自马来西亚的 Ledger Nano X 设备内部发现了隐藏的电子部件，尽管该设备的外包装看起来是出厂时的收缩膜密封状态。
主要行业人物和经销商的交叉参与加剧了对硬件钱包完整性的审查，将聚光灯投向了针对全球加密货币用户的供应链攻击所持续存在的风险。
