Hacked?

Is it possible to be hacked if I am swapping airdropped tokens on Solana for other tokens? I’ve already accepted my loss and only a portion of my tokens were transferred from my wallet.

Here is the transaction hash

It went to this wallet

The strange thing is this is the only transaction this wallet has, and it only took a portion of my tokens instead of the full amount.

Can anybody explain what happened here? I know my tokens are gone, but just for future purposes it’d be good to know how this happened. Thanks so much.
