Ledger Finds Physical Hardware Tampering in Crypto Wallet Investigation
Cryptocurrency hardware wallet manufacturer Ledger has confirmed the discovery of a rogue electronic component inserted into an affected user device. The finding represents the first concrete evidence of physical supply chain tampering in an ongoing investigation into reported cryptocurrency thefts involving wallets sold through Southeast Asian authorized reseller CryptoBilis.
The unauthorized hardware modification was designed to tap into internal communication lines between device components and the display screen, rather than breaching the primary secure element chip that generates and stores private keys. As a precautionary measure, CryptoBilis has suspended sales of all hardware wallets while the inquiry continues. Independent security researcher Mark Karpelès also verified the presence of hidden hardware after inspecting user photos and dismantling an affected Ledger Nano X sourced from Malaysia.
Ledger is collaborating with law enforcement authorities and contacting affected customers to determine how many devices contain the modification and whether the implant facilitated the thefts. Wallet owners and investors should monitor official announcements as investigators attempt to trace the origin of the physical tampering.
