TL;DR: I lost $165k in ETH from my wallet moments after it was deposited. It went to a new wallet (0x4b9e0ddabad6dff604db3d827f5fa7e1c6952aa8). I didn't use my Ledger, and that's a decision I'm paying for dearly. If you can help trace the transaction or the wallet, please share your advice. Keep your crypto assets secure, folks. It's a hard lesson I've learned firsthand.
This is a sweeper bot which is popular hacking techniques when you exposed your private key through phishing or malware. This is huge amount and you should hire someone to track it, hoping that hacker will deposit on centralized exchange.
This money is too huge to be stored on a software wallet alone. You knew your mistake and I'm sure this a great lesson to teach newbs here.
