Cryptocurrency hardware wallet maker Trezor says an August data breach at its shipping and logistics provider, ShipMonk, affects an additional 67,000 U.S. customers.
In total, the breach has affected 81,000 customers after Trezor initially disclosed on August 13 that attackers accessed the data of nearly 14,000 customers, including their full names, shipping addresses, email addresses, and phone numbers.
As the company explained at the time, the incident also affected customers in Brazil, Colombia, Italy, Portugal, Sweden, and the United Kingdom who received orders between May 10 and August 8, 2026.
On Friday, it published an update to confirm that the breach impact has expanded after ShipMonk failed to delete the exposed data from its systems as required by Trezor's contract and data policy.
"Another 67,000 customers from the US who ordered between November 2019 and August 2021 were affected, with their full details (name, email, phone number, shipping address, order number) exposed," Trezor said.
