No funds ever recovered from Lazarus group as far as I know, there have been some attempts that were stopped before losing money but once it happened then that's it because we are talking about North Korea here.
But fortunately Bybit managed to cover the 1.5bn hack with other means that might give the confidence back to their users but I wouldn't try them unless there's no other options available for me.
Once the money is gone from our wallets, it's gone. Recovering money from a hacker group is next to impossible.
The hack was one of a sophisticated type of attacks and very well planned one.
Not sure if you read that out but they literally had to get hold of the servers physically to achieve their goal.
But Bybit still refunded the money to their users just like Binance and so I think they can still be trusted.
