Hacking / Scamming Attempt - Similar Looking Addresses

PSA. I made a somewhat large transfer of ETH from one of my accounts to another one. Few hours later I got a tiny (0.00001 eth) transaction from an address that looked exactly like my own. The first and last characters matched. This is probably a hacking attempt, probably trying me to use that account instead of mine if I wanted to transfer funds back.

This is the originating address that funded the fake one: https://etherscan.io/address/0x66eca10c4f288cd310c234c0d9c73d47c5e1a738
