Ledger is investigating a sophisticated supply chain attack involving unauthorized hardware implants in its cryptocurrency wallets. The implants, discovered in devices sold through the Southeast Asian reseller CryptoBilis, are designed to intercept 24-word recovery phrases displayed on the device screen and transmit them to attackers via an embedded eSIM using LTE cellular networks. Because these rogue components do not alter the device’s core security chip or firmware, the wallets continue to function normally and pass Ledger’s authenticity checks, allowing the theft to occur undetected.

Forensic investigations reveal that criminals physically tampered with genuine devices before they reached consumers. Blockchain investigators and Chainalysis have updated damage estimates, with recent figures placing total losses between $90 million and $102 million. The security incident has expanded beyond Southeast Asia, with reports of similar hardware modifications appearing in devices purchased through MediaMarktSaturn in Europe. In response, MediaMarktSaturn has suspended the sale of Ledger products, and Ledger has requested that distributors in several Southeast Asian nations halt sales pending further investigation.

Former Mt. Gox CEO Mark Karpelès has criticized Ledger’s response, alleging the company received reports of these implants as early as December 2025 but did not issue a public post until March 2026. Karpelès accused Ledger of downplaying the incident by framing it as isolated to a specific reseller. In response to the crisis, Karpelès announced a project to develop an inexpensive device to detect unauthorized antenna components using low-power radio signal and resonance testing, intending to make the technical specifications public so users can build their own detectors.
