Trezor Cuts Reseller Count After Ledger Supply-Chain Issues

After supply-chain incidents involving rival Ledger, hardware maker Trezor announced it has cut back on the number of resellers it partners with.

In a Tuesday post on X, the Prague-based firm stated it was currently reviewing its list of vendors.

The company also noted that no problems with Trezor hardware have been reported. “Let us be very clear: there is not a single piece of evidence that Trezor devices have been compromised,” the company wrote.

“This is a preventive step, taken out of an abundance of caution.”

Last week, Ledger, which makes signing devices, said it launched an investigation after Southeast Asian customers reported losing funds following purchases from Malaysian reseller CryptoBilis.

Following recent supply-chain incidents, we decided to reduce the number of resellers so we can more effectively check those we work with.

Let us be very clear: there is not a single piece of evidence that Trezor devices have been compromised.

Ledger later revealed that one affected user's device had an unauthorized hardware implant inside it.

Since then, additional reports of devices that seem to have been tampered with have emerged on social media. However, Ledger stated on Tuesday that only devices purchased from CryptoBilis have been connected to lost funds.

The company added that it has only verified an unauthorized hardware implant in one affected device. According to Ledger, the implant could read a seedphrase when it displayed on the device.

Ledger did not disclose the amount of money lost, but blockchain investigator Specter claimed that $86 million had been taken from devices.

“We have not confirmed the total number of affected users or the total value lost,” Ledger added on X. “Figures circulating online come from third parties and Ledger has not fully verified them.”

Bitcoin Magazine received no response from Ledger regarding their inquiries.

Ledger also noted that CryptoBilis has ceased selling devices. It advised customers who purchased from CryptoBilis not to set up their devices and to get in touch with Ledger's support team.

This year, hardware wallets have been under attack from criminals. In July, hackers managed to steal nearly $120 million worth of bitcoin from Coldcard users through a firmware bug.

Coinkite, the Canadian manufacturer of the popular devices, explained that the bug caused faulty seed generation, enabling hackers to guess investors' seedphrases.

In another incident last month, Trezor reported that approximately 81,000 customers had their personal details exposed following a data theft from its third-party fulfillment partner.

Earlier this year, scammers accessed customer information through Ledger's payment processor Global-e to send phishing emails.
