I got robbed 0.5 eth

hey guys, my keys got compromised somehow, I barely use metamask. Somebody drained 0.5 eth from Binance Smart Chain and then on Eth Mainnet he got like 7$ of Eth.

This is the guy who stole it, because he transferred it to himself: https://bscscan.com/address/0x6d9e0448a0ccb750acf700cb405444c15a454582#tokentxns

My drained wallet is: https://bscscan.com/address/0x14b3d1d05d90e7bb9ef9847e92ca11dba10d1fcb

What can I do? I'd like to watch if he sends this to a KYC Exchange. Thanks
