Summary
MediaMarktSaturn has pulled Ledger hardware wallets from all its stores and online platforms globally due to reports of tampered devices. The decision was made as a precaution after a German customer reported a hardware implant in a Ledger wallet. Ledger confirmed no fund losses were reported and said no infrastructure or system breaches had been identified, coordinating the sales suspension with MediaMarktSaturn.
Why it matters
The removal signals heightened concerns about the security of hardware wallets, which are considered critical for safe cryptocurrency storage. The incident highlights risks posed by physical tampering and unauthorized implants that could transmit recovery phrases, potentially endangering user assets. The source does not explicitly state how this development will affect broader markets or policies.
Key context
The security alerts began after Ledger investigated losses linked to devices from Southeast Asian reseller CryptoBilis, where implants were transmitting users’ recovery phrases via cellular networks. Complaints also surfaced about unauthorized components found in wallets bought from multiple MediaMarkt locations. Additionally, former Mt. Gox CEO Mark Karpelès reported a similar implant in a Ledger product bought at Singapore airport, which Ledger referenced without direct comment.
Key numbers and entities
Entities mentioned include MediaMarktSaturn (parent of MediaMarkt), Ledger (hardware wallet maker), reseller CryptoBilis, the customer "Johannes" on X, and Mark Karpelès (former Mt. Gox CEO). No specific financial figures or quantitative data are provided.
What remains unclear
The source does not clarify how widespread the tampering issue is beyond the reported cases, nor if further compromised devices have been found. Details on how the implants were physically inserted or how long the tampered products may have been in circulation are not provided. Ledger’s response to the Singapore airport incident remains indirect and unresolved.
