Hardware wallet manufacturer Trezor has issued an alert to approximately 14,000 users after discovering that customer information was compromised through a security incident involving ShipMonk, its third-party logistics provider.

The security breach was publicly disclosed on August 13, 2026. According to Trezor’s statement, 11,742 users had their complete personal details compromised, including full names, email contacts, phone numbers, and complete shipping addresses. An additional 1,947 individuals had partial information exposed, specifically their names, city locations, and email addresses.

Identifying Affected Users

The breach impacts individuals who ordered Trezor hardware between May 10 and August 8 in seven countries: the United States, United Kingdom, Sweden, Colombia, Brazil, Italy, and Portugal. Notably, those who made purchases via Amazon remain unaffected since those shipments are managed through a different logistics provider.

The company has sent direct email notifications to every individual whose data was compromised. Users who haven’t received such communication can assume their information was not affected by this incident.

Trezor emphasized that the breach occurred exclusively at ShipMonk’s systems, leaving Trezor’s own infrastructure untouched. “Your Trezor device is secure,” the company reassured users. The actual threat to customers is secondary, manifesting primarily through social engineering attacks.

Cybercriminals may leverage the stolen data to launch sophisticated impersonation campaigns, posing as Trezor representatives, financial institutions, or cryptocurrency platforms through fraudulent emails, telephone scams, or physical mail. Users should maintain skepticism toward any unsolicited communications purporting to be from Trezor.

Escalating Cybersecurity Risks in Cryptocurrency

Data compromise incidents continue to surge worldwide. Cybersecurity analytics provider SentinelOne reports a 17% increase in breaches during 2026 versus the previous year, with approximately 2,090 cyberattacks happening globally every week.

Compromised personal information often circulates in underground markets for extended periods. Criminal organizations have exploited residential addresses to extort victims for payments ranging from $700 to $1,000, while others have shipped counterfeit hardware wallets to unsuspecting targets.

Direct physical threats against cryptocurrency owners are also intensifying. Blockchain security company Certik documented $124 million in losses from in-person coercion attacks during the initial six months of 2026.

This incident marks an unprecedented event for Trezor across its 13-year operational timeline—the first occasion where customer telephone contacts and residential addresses have been exposed. Earlier security events in 2024 and 2022 impacted support platform accounts and email information, but excluded physical delivery details.

Importantly, Trezor’s proprietary firmware and device-level security protocols have maintained a perfect record against remote intrusion attempts aimed at fund theft.

Competing hardware wallet provider Ledger experienced a comparable third-party data exposure in January 2026 through its e-commerce vendor. Previously in 2020, a Ledger breach impacted nearly 300,000 individuals, subsequently leading to fraudsters distributing counterfeit devices to those affected.

Trezor has verified that to date, no compromised information from this incident has surfaced on public forums, been traded commercially, or utilized in any fraudulent schemes.
