What should I do if Trezor Model T prompts "Security risk"?

If your Trezor Model T displays a 'Security risk' message, it's crucial to address this issue promptly to ensure the security of your cryptocurrency assets. This warning typically appears when there is a potential threat to your device or when the device detects unusual activity. Here's a detailed guide on how to handle this situation.

Understanding the 'Security Risk' Message

The Trezor Model T is designed with robust security features to protect your cryptocurrencies. When the device displays a 'Security risk' message, it indicates that the device has detected something unusual that could potentially compromise your funds. This could be due to a variety of reasons such as unauthorized access attempts, outdated firmware, or even a tampered device.

Immediate Actions to Take

Upon seeing the 'Security risk' message, it's important to take immediate action to safeguard your assets. Here are the steps you should follow:

• Disconnect the Device: Immediately unplug your Trezor Model T from your computer or any other device it is connected to. This helps to prevent any ongoing threats from continuing.
• Check for Physical Tampering: Inspect your Trezor Model T for any signs of physical tampering. Look for any unusual marks, scratches, or modifications that you did not make.
• Do Not Enter Your PIN: If the message appears while you are in the process of entering your PIN, do not proceed. Entering your PIN could potentially expose your device to further risks.

Updating Firmware

One of the common reasons for a 'Security risk' message is outdated firmware. To update your Trezor Model T firmware, follow these steps:

• Visit the Official Trezor Website: Go to the official Trezor website to download the latest firmware.
• Download the Trezor Bridge: Ensure you have the latest version of the Trezor Bridge installed on your computer.
• Connect Your Trezor Model T: Reconnect your Trezor Model T to your computer using the USB cable.
• Open Trezor Suite: Launch the Trezor Suite application on your computer.
• Initiate Firmware Update: Follow the on-screen instructions in the Trezor Suite to initiate the firmware update. The process will guide you through backing up your device and installing the new firmware.

Performing a Wipe and Recovery

If the 'Security risk' message persists even after updating the firmware, you may need to perform a wipe and recovery of your Trezor Model T. Here's how to do it:

• Backup Your Recovery Seed: Before wiping your device, ensure you have your recovery seed securely stored. This is crucial for recovering your funds later.
• Wipe the Device: In the Trezor Suite, navigate to the 'Settings' menu and select 'Wipe device.' Confirm the action on your Trezor Model T.
• Recover Your Wallet: After wiping the device, you can recover your wallet using your recovery seed. In the Trezor Suite, select 'Recover wallet' and follow the prompts to enter your recovery seed.

Checking for Malware

Another potential cause of the 'Security risk' message could be malware on your computer. To check for and remove malware, follow these steps:

• Run a Full System Scan: Use a reputable antivirus software to perform a full system scan on your computer. Ensure the antivirus software is up to date.
• Remove Detected Threats: If any threats are detected, follow the antivirus software's instructions to remove them.
• Reconnect Your Trezor Model T: After ensuring your computer is free of malware, reconnect your Trezor Model T and check if the 'Security risk' message persists.
