Hi
yesterday was some BTC stollen from my wallet (PC). I dont know how or who or how did this happened.
Will trezor help again this ?
Impossible to say, as you don't know how they were stolen.
Still trezor is the safest option currently.
All I can found that BTC was sent to 183u3xkUUqpVwJmmLqqt14cchS5Mu9CQk7 and then to 17gH1u6VJwhVD9cWR59jfeinLMzag2GZ43 .. but I had some secure things like firewall antispam .. .etc. on my computer .. but i looks it is not enough .. So I hope trezor will make it safe for next time.
Were you handling that wallet when the first transaction happened, or shortly before? - No, only incoming trancaction All i See is one transaction few hours befonr.
Do you use Dropbox or some other external storage? - No external (Inet) devices .. only my own NAS with firewall and restricted IPs
Was the wallet totally emptied, or only part of it? - tottlly empty after that attack
What software/hardware did you use to generate your private keys? - sorry but I dont understand this queston. Do you mean passwords? Or what type of keys?
