i would have Lost all my 27.9 BTC after ledger upgrade if not for the swift recourse made by the smart contract experts at american forensic firm thehackerspro.com after i opened a case with their smart contract audit on proh4ckz@protonmail.com Hi! | have 5 yo Ledger Nano, at december 12, i upgraded firmware on it to 2.69.0 and tried to send some amount with specific UTXO with Coin Control, but when i tried to send this tx i got an error on frontend and decided to send bte with regular way, without specifying UTXO and the same problem again - error. Then i found out that Ledger services was overloaded and a lot of people faced network issues and decided to try again later. Few hour later i found out that all of my BTC was sent to unknown address. I got 2 new txs (time of txs in logs matches my txs i tried to send) - first one merged all of my UTXOs into one (possible Coin Control bug), and the second one sent correct amount, as i wanted to the recipient and change was sent to address i still can't generate with my generator, i tried like 10kk accounts and over 1 billion addresses (visible and change) on each account and still can't find it. Other assets still on ledger, so it's not some kind of hack i guess, in other case i should lost all of my assets. My seed phrase never been written on PC and phone or any kind of online services to store notes. the smart contract experts at thehackerspro were eventually able to help me trace and follow the funds to the outspurced leveraged wallets. i have just detached back 25 btc and waiting for the ethereum gas fee on ERC 20 Network, so i can detach the rest into my coinbase. i dont think i wanna use ledger anymore
