@AsiP this is likely a scam transaction like address poisoning or fake airdrop offers.

Don’t worry—your wallet is safe. This transaction is like email spam. Since crypto networks are public, such transactions can’t be removed or avoided entirely. Trezor Suite will often flag them as suspicious to help protect you, but it’s important to understand that regardless of whether it’s flagged, a transaction that you do not expect to see is likely any of the following:

  • Some transactions mimic ones you’ve sent before, hoping you’ll mistakenly copy the scammer’s address next time. The address and the amount sent usually look similar to make it more realistic.
  • Other transactions may advertise fake rewards or airdrops, leading you to phishing websites.

Here’s how to stay safe:

  • Avoid copying addresses from your transaction history; obtain them directly from the recipient of the transaction, such as your exchange or wallet.
  • Never visit links promising airdrops, rewards, or free tokens. These are often scams designed to steal your funds.

I had the same issue and found a transaction like this. I contacted Trezor and they told me that ‘Unauthorised transactions’ mean that someone has my passphrase and I need to move to a new Trezor. Obviously that told me incorrect information and I haven’t been able to have any correspondence with them since. Brian if you are out there please follow up mate.

So in summary in these cases, you can only lose funds if you unknowingly copy the address from one of these spam transactions and send it to the WRONG address? i.e. you don’t check the outgoing address on your Trezor? And running through all the numbers in the address as a check
is wise?

the important part is, what are you comparing the address to?

If you copy one of the fake addresses from your history, and compare it to the Trezor screen, you’ll just see the same address. Your Trezor doesn’t know where the address came from, it can’t tell that it’s a fake.

What you need to do is compare the address at the source. If it is an address from your exchange, log in to the exchange and compare that.
Or, write down the address on a piece of paper and then always compare to the piece of paper.

Important thing to know is that the fake addresses very often have the same beginning and ending as the real thing. You really have to check most of it. (not necessarily all of it, but for a layperson it’s difficult to tell when it is safe to stop. better to compare it in full)
