Hardware crypto wallet provider Trezor says the personal information of nearly 14,000 people was compromised in a data breach.

The incident, it says, did not involve Trezor’s systems but rather its third-party shipping provider, ShipMonk. Trezor was notified of the attack on August 10.

Customers in the US, the UK, Sweden, Colombia, Brazil, Italy, and Portugal who placed orders between May 10 and August 8 were affected.

“We’re extremely sorry to inform our community that customer personal information, including full names, phone numbers, email addresses, and shipping addresses, has been accessed by an unauthorized actor during this breach,” Trezor says in a notice.

Hackers stole the names, addresses, email addresses, and phone numbers of 11,742 customers, as well as the names, cities, and email addresses of 1,947 customers. Trezor shared the information with ShipMonk for order delivery purposes.
