Hi.

Looking for some help. Yesterday I received my Ledger nano x from Ledger. I opened the box which didn't seem tapered with at all, setup the device and recovered the wallet to it so it's the same as my existing nano s. I then sent a test transaction for $1.00 worth of BTC to my Coinomi wallet. The transaction all looked legit and went through fine, fees and all it was a little over $3.00 worth of BTC 0.0004 and change. Ledger live shows the transaction fine in the history and my ledger live balance updated to show the balance minus the funds I sent.

However when I check blockchain explorer the transaction ID shows and additional 0.057 BTC sent from my wallet address in the same TX to an unknown bitcoin address. My balance on blockchain explorer shows a different amount than on ledger live even after ledger live has synchronized. On blockchain explorer the extra 0.57 BTC has been deducted from my balance but in ledger live it has it been. So in sending a $1.00 BTC transfer i lost over $450 from my wallet. Again I didn't send the 0.057 BTC, I checked the transaction id fees etc on the ledger before authorizing and everything seemed legit. Does any one have any idea what's happening? Is my ledger possibly hacked? I"m scared to move any remaining funds as I don't want to lose more.

My best guess, without knowing your transaction id or address you funded, would be that your ledger just created a change address. This is the way the protocol works.

You probably had a 0.0574 unspent output funding your address, you used this output as an input to create a new transaction. 0.0004 funded your coinomi wallet, 0.057 funded a change address generated by your hardware wallet.

You do know coinomi has had several vulnerability's in the past, right? (unrelated to this topic tough)
