Data Breach Roundup (Aug 28 - Sep 3, 2026)

The company has not disclosed the number of people impacted, but said data affected potentially includes email, address, phone number, national ID number, or financial information. The breach also affected the Social Security numbers, financial account information, credit/debit card numbers, and driver's license information of 436 Hasbro employees in Massachusetts. The incident likely took place around March 28, as that's when Hasbro disclosed a cyberattack and temporarily took systems offline.

That’s a lot of breaches.

Two days ago, we received an update from our shipping provider, ShipMonk. We’re deeply saddened to share the news that the recent data breach affects more customers than originally thought.

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.

All affected customers have been emailed directly. If you didn’t receive an email, then you are not affected.

Throughout our entire relationship with ShipMonk, we repeatedly requested and received written assurance confirming the deletion of the data, in line with our contract, data policy, and past communications. We are very disappointed that, despite receiving this confirmation, the data was not deleted in their systems.

Trezor systems were not compromised, and your device is secure. But please be alert for fake emails, phone calls, fraudulent letters, and potential risks to physical security.

NEVER share your wallet backup with anyone or type it into a website.

We’re terribly sorry to everyone affected. We take this matter very seriously and are working to ship anonymous delivery ASAP, so you can protect your personal information when placing an order.

We have some difficult news to share. Unfortunately, one of our shipping providers has experienced a data breach that exposed sensitive order data. This affects new customers in the US, UK, Sweden, Colombia, Brazil, Italy, and Portugal who received an order within the 90 days prior to August 8th, 2026.

The data exposed:

- Full names

- Shipping addresses

- Phone numbers

- Email addresses

The incident affects 11,742 customers with full exposure (name, email, phone number, shipping address) and 1,947 customers with partial exposure (name, city, email). The breach is limited due to Trezor’s strict 90-day data storage policy (we were also able to negotiate the same terms with fulfillment partners, who follow the same policy).

All affected customers have been contacted separately by email.

Our systems and devices remain secure, but affected customers could experience an increase in phishing attempts.

NEVER enter your wallet backup on a website or share it with anyone, and only check for updates on official Trezor channels.

We are deeply sorry to the community and those affected.
