Former Mt. Gox CEO says spy module with SIM chip found in Ledger Nano X

Former Mt. Gox CEO Mark Karpelès said he found a suspected spy module inside a Ledger Nano X hardware wallet delivered from Malaysia, as Ledger investigates large-scale crypto theft affecting users who bought products through Southeast Asian authorized reseller CryptoBilis. Karpelès said the device’s shrink wrap appeared intact, but a hidden module had been installed where the internal display pad should have been. The device was said to include a SIM chip. Karpelès also released photos comparing a genuine circuit board with the suspected module and argued tampering devices have evolved from manually wired modifications to circuit-board-style components that can be mistaken for authentic parts. He added that even when a device’s exterior and packaging appear undamaged, internal tampering may be difficult to detect visually. Ledger has not officially confirmed the module’s function or any link between the device and the recent crypto theft cases involving CryptoBilis buyers. It therefore remains unclear whether the device actually had information-stealing capabilities or was used in the recent theft incidents.
