Former Mt. Gox CEO Mark Karpelès said a Ledger Nano X purchased from Malaysia contained a spy module despite intact shrink-wrap packaging. He said the implant was hidden where the screen padding should have been and shared comparison photos of the original circuit board and the modified device.
Why it matters
Karpelès said hardware implants have evolved from hand-soldered wiring into circuit boards that can resemble original components. That makes supply-chain integrity a harder security problem for hardware-wallet users, even when packaging appears untouched.
Market impact
Karpelès is requesting device photos from affected users to identify similar implants and advised following Ledger's official security guidance. Ledger has not been shown to have confirmed the module's functionality or any connection to recent CryptoBilis customer losses. The report reinforces the need to verify hardware through official channels and treat unusual device components as a security warning.
