Hardware wallet maker Trezor disclosed on September 4 that a data breach at its shipping provider ShipMonk is larger than first reported, affecting roughly 67,000 additional U.S. customers, according to the company’s security update. Trezor said it learned on September 2 that the breach, first announced on August 10, also contained order data from its prior cooperation with ShipMonk between November 2019 and August 2021. The company added that it had repeatedly received written assurance from ShipMonk that the data had been deleted, only to find that the records remained in the provider’s systems.
