Trezor's shipping provider ShipMonk exposed names, emails, addresses of 13,689 customers. Device security intact but phishing wave expected. Anonymous delivery option in September.
Trezor, the hardware wallet maker, said a data breach at its shipping provider ShipMonk exposed personal information for 13,689 customers. The company stressed that the devices themselves remain secure but warned that affected users face a surge in phishing attempts.
In a blog post, Trezor said ShipMonk suffered an unauthorized access incident that leaked names, phone numbers, email addresses, and shipping addresses. Of the total, 11,742 customers had full exposure – all four fields. Another 1,947 customers had partial exposure limited to name, city, and email.
The breach affected orders fulfilled in the 90 days before Aug. 8, 2026, and shipped to the U.S., U.K., Sweden, Colombia, Brazil, Italy, or Portugal. “Affected customers were emailed today from [email protected]. No email means not affected,” the firm said.
Trezor said scammers are already trying to use the leaked details to access wallets. It urged customers to remain vigilant against phishing messages that appear to come from Trezor.
To reduce future risk, Trezor is developing an Anonymous Delivery option that lets buyers order hardware wallets without linking the purchase to a home address or real-world identity. Users will choose a nickname or label ID and pick up the package at an automated parcel locker. Packaging will be unbranded with a generic sender label. The option is targeted for September in the European Union and by the end of the year in the U.S.
The incident follows a separate hack at Coldcard that, according to Galaxy Research, led to losses of up to $116 million in Bitcoin. Trezor's breach does not affect the security of its hardware; no private keys or wallet data were compromised.
