So the problem is that most players primarily pay attention to bonuses and all kinds of free giveaways. He also looks at the range of games and slots, because a casino should be interesting, but they usually look at security when it's too late and the money is lost.
When there are a lot of money there are a lot of hackers who want to hack such money.
There are a lot of easy money in casinos that is why hackers play much more attention for such money.
Security is very important thing for such kind of casinos.
There’s minimal cases of hack incidents on casino so far. I think you meant exploit or abuse bonuses since this is the most common problem of casino that offering bonuses with lousy ToS that can be exploited easily.
It give a big impact in the casino industry since bonuses is much harder to claim now compared before due to wagering requirements and other restrictions that will help casino retain the bonuses as much as possible.
