Hardware wallet maker Trezor is downsizing its network of authorized resellers and immediately halting shipments to affected distributors. The move comes as a preventive measure following reports that counterfeit hardware implants were inserted into devices made by competitor Ledger. Trezor stated that there is no evidence any of its own devices have been compromised.

The action highlights severe supply chain vulnerabilities in cryptocurrency storage. Ledger confirmed that at least one device sold by Southeast Asian reseller CryptoBilis contained an unauthorized cellular implant that captured screen data and leaked recovery phrases. Independent estimates suggest user losses could range between $72 million and $86 million, prompting major retailers to pull hardware wallets from store shelves and distributor platforms.

Impacted resellers will be formally removed from Trezor's authorized list on Jan. 1. In the meantime, investors and device owners are encouraged to buy hardware wallets directly from manufacturers, verify physical tamper seals, or adopt multisignature security configurations split across different vendors to mitigate single-device risks.

## Key points

- Trezor is scaling back authorized resellers and stopping shipments to prevent supply chain tampering.
- The security measure follows reports of unauthorized hardware implants discovered in devices made by competitor Ledger.
- The malicious implant captures screen information and transmits recovery phrases without modifying device firmware.
- Blockchain researchers estimate potential user losses from the compromised devices between $72 million and $86 million.
