Hardware wallets are supposed to be immune to such hacks,
the problem must be the client, address changing malware (
clipboard hijacking) or social engineering tactics.
Because if it's the seed, all of the wallet's balance should be wiped by now.
Questions:
- 1. Is the address: 32ZVUuEqNHmN4E3nEGwQ8G4L2awHyM9B7K belongs to you?
Because you've mentioned that almost half of the amount was sent, so this must be your change address. - 2. The address: 34Ad7ccMtEhcuN9j1YWvQwcQiwjoT2YGST also belongs to you?
If #1 and this are true, then that transaction was probably sent with your consent (unintentionally because of the possible reason above);
if not, there's a problem with your HW. - 3. Have you tried to send the same amount to another address prior to this "hack"?
