How Did the Spy Chips Avoid Detection
On October 13, 2026, Ledger disclosed that criminals had implanted spy chips in some of its hardware wallets sold through third-party retailers. The revelation came after multiple users reported unauthorized access to their cryptocurrency holdings. Mediamarkt, a major European electronics chain, immediately halted sales of Ledger devices across its stores. The freeze applies to all Ledger Nano S Plus and Nano X models pending investigation. No Ledger-owned retail channels were affected by the decision.

Ledger confirmed the tampering occurred after products left its manufacturing facilities but before reaching end users. The company emphasized that its secure element technology remained intact and that the attack required physical access to the device. Investigators are working with law enforcement to trace the origin of the compromised units. Ledger advised users to verify device authenticity using its official Ledger Live application.
What Steps Are Users Advised to Take Now
The malicious chips were designed to mimic legitimate components, making them difficult to spot during routine quality checks. They activated only when the wallet was connected to a computer running specific malware, which then transmitted private keys to remote servers. Ledger’s internal audit found no anomalies in device firmware or software signatures. The attack exploited a gap in physical security rather than digital vulnerabilities. Experts note that such supply chain interdiction requires significant resources and coordination. Ledger has since urged retailers to implement stricter verification protocols for incoming shipments.
Ledger recommends that all users check their device’s integrity through the Ledger Live app, which performs a cryptographic verification of the hardware. If the app detects any irregularity, users should cease use and contact support immediately. The company is offering free replacement units for any device confirmed to be compromised. Users are also advised to initialize their wallets in a secure environment and never share their recovery phrase. Mediamarkt has pledged to resume sales only after receiving clearance from Ledger and completing its own security audit. Both companies stress that user funds remain safe if the recovery phrase was never entered on a compromised device.
How can I tell if my Ledger device has been tampered with? Run the genuine check in Ledger Live; it will alert you if the device’s cryptographic signature does not match Ledger’s records. A failed check means the device should not be used.
Frequently Asked Questions
Are my cryptocurrency funds at risk if I used a compromised device? Only if you entered your recovery phrase on the compromised device while it was connected to an infected computer. The spy chip cannot extract keys without both conditions.
Will Mediamarkt refund customers who bought affected devices? Yes, Mediamarkt will provide full refunds or replacements for any Ledger device purchased during the affected period, regardless of whether it was compromised.
