Trezor Data Breach: 13,689 Customers Face Phishing Threats After ShipMonk Incident

Leading hardware wallet manufacturer Trezor has faced an unprecedented security incident: on August 12, 2026, the company disclosed a personal data breach affecting 13,689 customers following a compromise of its logistics partner ShipMonk. This is the first time since the company was founded in 2013 that customers’ phone numbers and delivery addresses have been compromised.

📊 Scale of the Incident: What Exactly Happened

On August 10, 2026, ShipMonk, one of Trezor’s key logistics partners, informed the company of unauthorized access to systems containing customer data. The investigation is ongoing, but the main parameters of the breach have already been established.

Affected Customer Statistics

• Full exposure: 11,742 customers (name, email, phone number, delivery address)
• Partial exposure: 1,947 customers (name, city, email)
• Total: 13,689 affected users
• Risk period: Orders placed from May 10 to August 8, 2026
• Affected countries: United States, United Kingdom, Sweden, Colombia, Brazil, Italy, Portugal

🎯 What Data Was Compromised

The breach affected exactly the information required by logistics partners to deliver physical products. It is important to understand that critical cryptographic data remained secure.

Compromised Data

• Customers’ full names
• Email addresses used for communication
• Phone numbers used by couriers
• Full delivery addresses
• Order numbers

Data That Was NOT Compromised

• Seed phrases: Never stored in Trezor or partner systems
• Private keys: Generated and stored only on the device
• PIN codes: Stored only on the device itself
• Passphrase: Never transmitted or stored
• Transaction history: Not connected to the shipping process

⚠️ Main Threat: Targeted Phishing Attacks

Although the security devices themselves were not compromised, the leak of personal information creates a serious threat through targeted phishing attacks. Attackers can use the exposed information to craft highly convincing fraudulent messages.

Types of Potential Attacks

• Targeted email attacks: Personalized emails impersonating Trezor and asking users to "verify" device information
• Phone vishing: Calls from fake "support representatives" using the victim’s real name and address
• Smishing: SMS messages containing links to fraudulent websites
• Physical mail: Letters using official-looking branding and requesting a "security update"
• Bank and exchange impersonation: Using leaked data to attack related financial accounts

Why These Attacks Are Especially Dangerous

Attackers can use real information to make scams more convincing:

• Addressing the victim by name creates a false sense of trust
• Mentioning the real delivery address reinforces the appearance of "legitimacy"
• Knowing the order number makes the message more believable
• Phone calls that include personal information are harder to recognize as fraudulent

🛡️ Recommendations for Protection Against Phishing

Trezor issued detailed recommendations for affected customers, but these practices are important for all hardware wallet users.

Signs of Phishing Attacks

1. Demand for immediate action: Legitimate companies rarely require instant responses
2. Requests for a seed phrase or PIN: Trezor never asks for this information
3. Suspicious links: Always verify the URL before entering any information
4. Unexpected messages: Be cautious with unsolicited contact
5. Pressure and urgency: Scammers often create artificial urgency

Protective Measures

1. Verify sources: Always cross-check information through Trezor’s official channels
2. Two-factor authentication: Enable 2FA on all related accounts
3. Email caution: Do not open suspicious attachments or links
4. Verify phone calls: Call back using official phone numbers to confirm legitimacy
5. Update passwords: Change passwords on related services

🔍 Data Retention Policy: Why 90 Days

Trezor uses a strict 90-day data-retention policy, which played a key role in limiting the scope of the breach.

Rationale for the 90-Day Period

The company selected this period as the minimum window necessary to cover the full order lifecycle:

• Delivery: Typical time required for an order to arrive
• Returns: Period during which customers may return products
• Replacements: Time needed to replace defective devices
• Refunds: Period required to process refunds

Data Deletion Process

After the 90-day period expires:

• Personal data is completely deleted from systems
• Remaining information is anonymized
• The same policy applies to all fulfillment partners
• Regular compliance audits are conducted

🛒 How to Protect Your Privacy When Placing Future Orders

Although it is impossible to completely eliminate data sharing when physical delivery is involved, there are ways to minimize exposure of personal information.

Current Privacy Strategies

1. Anonymous email addresses: Use temporary or alias email addresses that are not tied to your real identity
2. Cryptocurrency payments: Pay with cryptocurrency instead of credit cards
3. Disposable cards: If crypto is unavailable, use single-use virtual cards
4. P.O. Box: Use a post office box instead of your home address
5. Alternative addresses: Use a work address or the address of a trusted person

Upcoming Feature: Anonymous Delivery

Trezor announced the upcoming launch of an anonymous delivery feature:

• Special checkout: A separate checkout process requiring minimal personal data
• Locker pickup: Collection through automated parcel lockers
• Neutral packaging: No branding or indication of package contents
• Generic sender information: No specific information identifying Trezor
• Automatic deletion: Delivery identifiers deleted immediately after pickup

🌐 Context: Data Breaches in the Crypto Industry in 2026

The Trezor incident comes amid growing data-security problems across the cryptocurrency ecosystem. 2026 has been an especially difficult year for security:
