Sorry those coins are gone since transaction are irreversible and there's no other way to get those coins back unless if that hacker did decide to return those coins again which
is really an impossible thing to happen.

This is why we should really be careful and keen towards our security information and making all sorts of things to make it secure neither your wallet
or any platforms that you've been using which needed to have that 2fa or other layers of security.

People never learn until they do experience unfortunate events.
