I use a Ledger Nano S for my Monero GUI wallet. It’s been working great for a few months, but today when I tried to log in, Monero Wallet is saying “Couldn’t open wallet: device not found.”
I installed Monero GUI wallet on another computer, copied the .key file over and tried to unlock the wallet and got the same error message. Inputting the wrong password still gives me the incorrect password error message as usual. I asked around in the /r/Monero and they suggested I create a new wallet using the mnemonic seed plus block height, which I unfortunately didn’t write down because I noobishly thought this information was stored on the Ledger itself. So now I have no idea whats up with my funds. I can’t even check the wallet balance to confirm if I got hacked because I can’t get into the wallet.
Does anybody know if it is possible for somebody to steal my crypto without physical access to the Ledger if they had a backdoor in my computer? Thank you
