transactions – scam lost 14.5 BTC

Last night I made the mistake of using the website (while offline) to generate a wallet. I sent 0.1 then 14.5 BTC to it, and then 1 min later 14.51 was sent out to another paper wallet

here is the wallet I created and you can see the transactions

any advice on what I can do. I’ve accepted the loss and the lesson (should have used the offline generator) but want to make sure this doesn’t happen to others
