ETH Ledger暂停东南亚经销商CryptoBilis销售业务，涉及金额高达近9000万美元
硬件钱包制造商Ledger宣布，已暂停其东南亚经销商CryptoBilis的销售业务。此前，通过该渠道购买设备的客户资金遭到窃取，损失估计在7200万至9000万美元之间。
Ledger表示，公司正在对此次损失进行调查，并要求CryptoBilis在调查期间暂停所有Ledger设备的销售和发货。针对过去90天内从该经销商处购买设备的用户，Ledger建议：如果设备尚未激活，请勿进行设置；如果设备已在正常使用中，请立即将资产转移至配备全新助记词的新Ledger设备中。公司承诺将在调查进展过程中持续向客户通报最新情况。
链上数据估算存在差异
关于具体损失金额，不同分析机构的估算结果有所出入。分析师Specter追踪了十个收款地址，统计了来自以太坊、波场和比特币网络中数百个受害者钱包的资金流入，指出总损失已超过8600万美元，且这一数字仍在上升。分析师tanuki42估计损失超过7200万美元，而MistTrack的估算接近9000万美元。截至目前，Ledger官方尚未确认具体的美元损失数额。
疑似供应链攻击而非软件漏洞
CryptoBilis claims to be an authorized distributor of Ledger products in Malaysia and sells related equipment in Indonesia, Malaysia and the Philippines. The company has not yet responded to requests for comment.
It is speculated that the mechanism for this incident did not stem from a flaw in the Ledger software itself, but from the tampering of the supply chain. Zhao Changpeng, founder of Binance, pointed out that existing information indicates that this was a supply chain attack against a single supplier, and only a few people purchased counterfeit or tampered equipment.
Security researcher Taylor Monahan emphasized that there is no zero-day vulnerability in Ledger products and warned that hasty transfers of funds could expose users to a greater risk of phishing than the incident itself.
Some stolen funds have been laundered, and the freezing of stablecoins has triggered new developments
Some stolen funds have already flowed. On-chain tracking data shows that suspected attackers have laundered approximately 430 ETH pieces, worth approximately US$1.07 million, through the currency mixer Tornado Cash. In addition, approximately $70.6 million was still held in the Arkham tracking wallet linked to the theft.
Tether has frozen USDT funds related to stolen addresses. Subsequently, attackers began to exchange USDT for USDD, a stablecoin based on the wavefield network, because Tether was unable to freeze USDD.
Ledger declined further comment and its internal investigation is still ongoing.
