Trezor Data Breach Expands to 81,000 Customers, With 67,000 U.S. Users Affected
A data breach involving hardware wallet maker Trezor has affected far more customers than initially reported, with the number of potentially impacted users rising to around 81,000 from 13,689, according to information shared by The Crypto Times on X.
The expanded disclosure includes another 67,000 customers in the United States whose names, phone numbers and shipping addresses were reportedly exposed. The information raises concerns beyond digital account security, as Trezor has warned affected customers about potential physical security risks.
Breach Scope Expands Significantly
The latest figures represent a substantial increase from the 13,689 customers initially identified as affected by the breach. The newly reported number indicates that the incident involved a considerably broader set of customer information than first understood.
According to The Crypto Times, Trezor said the exposed information linked to U.S. customers included names, telephone numbers and shipping addresses. Such details can provide information about where customers live or receive shipments, creating risks that extend beyond the compromise of personal data itself.
Trezor has reportedly contacted affected customers directly as part of its response and has warned them to remain alert to potential physical security threats.
ShipMonk Data Deletion Under Scrutiny
The incident also centers on data previously handled by ShipMonk, a fulfillment company associated with the affected information.
Trezor said ShipMonk had repeatedly confirmed that the relevant customer data had been deleted. However, the company later determined that the information had not in fact been removed.
The discrepancy between the deletion confirmations and the subsequent discovery of retained data is a key element of the breach. It also helps explain why the scope of affected customers has expanded from the original figure.
The reported exposure involves personal information rather than a direct disclosure of cryptocurrency wallet recovery credentials in the information provided by The Crypto Times. Trezor's warning, however, underscores why compromised customer records can present risks even when sensitive wallet credentials are not involved.
Trezor Warns Customers About Physical Security Risks
Trezor's response has focused not only on protecting affected customers' information but also on the possibility of physical security threats arising from exposed addresses and contact details.
Customers whose names, phone numbers and shipping information were disclosed could potentially become targets of unwanted contact or attempts to exploit their knowledge of a person's association with a hardware wallet provider. Trezor has therefore urged affected users to take the physical-security implications seriously.
The company says it has contacted customers affected by the incident directly. The increase in the reported number of impacted users means those notifications are now relevant to a much larger group than initially disclosed.
The latest figures reported by The Crypto Times put the total number of affected customers at around 81,000, while 67,000 U.S. customers were reportedly among those whose names, phone numbers and shipping addresses were exposed.
