Account hacked - sophisticated attack

[Petosiris]

I think what happened to you is similar to this:

Zero USDT transfer phishing/scam

what is happening here is a new kind of scam, where scammers send 0 transactions from their fake generated address that has first 4 and last 4 characters same. Then they rely on people only checking these characters and copying their fake address instead of a legit one from their history. Described in more detail in here: Basically, you always have to be sure you are sending to the address you want, always verify in full and copy only from the legit source.
