BTC Ledger discovered tampering with hidden chips in hardware wallets was related to the loss of encrypted funds.
Ledger, a hardware wallet manufacturer, said it found a hidden chip implanted in equipment sold through third-party dealers. The discovery was accompanied by reports of approximately $92 million to $93 million in stolen funds.
Investigation details and parties involved
According to reports describing the discovery, the company identified the seller as "CryptoBilis." It is reported that the implant was discovered during an investigation into tampering units that deviated from Ledger's official sales channels and reached customers 'hands.
Ledger produces devices designed to keep private keys offline and isolated from connected systems. This design is often the core selling point of hardware wallets. Hidden components within the shell can undermine this isolation, potentially allowing attackers to unwittingly access or steal sensitive keying material.
Differences in financial loss estimates
Reports describing this discovery link tampered wallets to a broader pattern of cryptocurrency theft. The estimated amount of damage associated with the incident varies depending on the source, with the figures cited being $92 million or $93 million, respectively. The difference has not been publicly resolved, and it is unclear whether the different numbers reflect separate loss statistics or simply rounding in the report.
Supply Chain Security Risk Warning
Ledger凭借安全元素芯片和固件验证技术建立了声誉，旨在在设备到达客户之前检测篡改行为。该公司长期以来一直警告买家直接从Ledger或其授权合作伙伴处购买，而不是从第三方市场或来源不明的经销商处购买。此案似乎正是围绕这一风险展开：经销商分发在销售前已被篡改的设备。
供应链篡改是硬件安全行业已知的威胁，并非加密货币钱包所独有。攻击者可以在运输途中拦截产品，修改内部组件，然后重新密封包装以使其看起来未开封。虽然安全研究人员此前曾针对硬件钱包演示过此类概念验证攻击，但确认的重大财务损失的现实案例相对较少。
当前进展与市场影响
Ledger尚未详细说明受影响设备的范围，也未披露 alleged 芯片提取资金的确切机制。据报道，Ledger对此事的调查仍在进行中。随着调查的继续，可能会浮现更多技术细节，包括植入物的运作方式以及受影响的设备数量。
关于硬件钱包中发现与经销商有关的硬件植入物的消息，可能会重新引发业界对硬件钱包供应链的审查。如果调查结果得到完全证实，买家可能面临更仔细地验证购买渠道的压力，而对直接从制造商处销售的需求可能会增加。
Whether the reported loss amount is $92 million or $93 million, the scale of the damage attributed to the incident is highlighted. If losses of this magnitude are verified, the case could become a reference point for managed service providers and wallet manufacturers to communicate supply chain risks to retail users in the future.
