How to protect Trezor from phishing attacks? (Safety tips)

Verify Official Purchase Channels

1. Always buy Trezor devices directly from trezor.io or authorized resellers listed on the official website.

2. Avoid purchasing from third-party marketplaces, social media ads, or unofficial Telegram/Discord groups.

3. Check domain spelling carefully—typos like “trezor-store.com” or “trezor-official.net” are common phishing traps.

4. Confirm HTTPS and valid SSL certificate before entering any personal or payment information on purchase pages.

5. Upon delivery, inspect packaging for tampering signs such as broken seals, mismatched labels, or altered USB ports.

Secure Firmware and Recovery Setup

1. Never install firmware updates from links received via email, SMS, or unsolicited notifications.

2. Always download firmware manually from trezor.io/firmware after verifying the SHA256 checksum published on the official blog.

3. Generate your 12- or 24-word recovery seed exclusively on the Trezor device screen—never type it into a computer or phone.

4. Write down the seed manually using pen and paper; never store it digitally or take screenshots.

5. Double-check each word during setup against the official BIP-39 wordlist displayed on the device itself.

Transaction Confirmation Best Practices

1. Always verify recipient address, amount, and network fee on the Trezor screen—not just in MetaMask or other wallet UIs.

2. Reject any transaction where the device displays an unfamiliar contract address or unexpected token symbol.

3. Disable “blind signing” unless absolutely necessary—and only after confirming the external tool’s legitimacy through independent research.

4. Use Trezor Suite’s built-in blockchain explorer to cross-check pending transactions before final approval.

5. If the device prompts for confirmation without showing full details, disconnect immediately and investigate the dApp source.

Avoid Fake Wallet Interfaces

1. Bookmark trezor.io and never navigate to it via search engine results that lack verified site badges.

2. Never enter your recovery phrase or PIN into any web form—even if the page looks identical to Trezor Suite.

3. Install browser extensions like MetaMask only from official Chrome Web Store or Firefox Add-ons pages—not from GitHub gists or Discord file shares.

4. Check the URL bar for subtle misspellings: “trezor-suite.app”, “trezorsuite.dev”, or “trezor-login.net” are all malicious domains.

5. Enable Trezor’s passphrase protection to add a second layer of authentication that exists only in your memory.

Frequently Asked Questions

Q: Can phishing sites mimic Trezor Suite’s login screen?Yes. Attackers clone the interface perfectly—including animations and layout—but intercept credentials entered into fake forms. Trezor Suite never asks for your recovery seed online.

Q: Is it safe to use Trezor with decentralized exchanges like Uniswap?Yes—if you connect via WalletConnect or direct USB and confirm every transaction on-device. Never approve unlimited token allowances without reviewing the smart contract address first.

Q: What happens if I enter my PIN on a phishing site?Nothing—the PIN is only used locally on the device. However, entering your recovery phrase or passphrase on any website will result in immediate asset loss.

Q: Does Trezor support anti-phishing word lists like Ledger does?No. Trezor relies on hardware isolation and manual verification instead of domain-binding anti-phishing words. Its security model assumes users validate all on-screen data before pressing the physical button.
