According to BlockBeats, on October 13, former Mt. Gox CEO Mark Karpelès confirmed that a Ledger Flex hardware wallet purchased at a Singapore airport retailer contained an implanted spy module. The device, acquired by user Ben Yorke during summer and never used, revealed suspicious scratches before disassembly. Karpelès published photos and video showing an additional circuit board and wiring hidden at the device's base, capable of intercepting seed phrase input by monitoring screen communications.
This follows an earlier case where Ledger devices distributed through Malaysian retailer CryptoBilis were compromised, resulting in over $86 million in stolen assets. The airport channel discovery indicates the issue is not isolated. Community reports document similar implants found in devices purchased through European official retailers and Philippines channels, with injection techniques evolving from hand-soldered components to more sophisticated mass-produced circuit boards.
