Was I hacked or no?

I am using a ledger nano x to stake my ETH with lido, about an hour ago a deposit was made into that ledger account for the same amount I staked several months ago. At the same time that deposit was made a larger amount of ETH that I hadn’t staked yet was removed from a separate account (also on the nano x), and sent to this contract address without my authorization.

No one in my household knows I have a ledger. My seed was written in a piece of paper kept in a safe in my bedroom. What is this contract address? And if I was hacked how come they didn’t take any of the other coins there?
