I think this is the first time that kucoin got hacked if I'm not wrong. I thought kucoin has a solid security but still hacker destroyed it. Damn 150 million dollars was lost, lucky hacker that money is too much for living. Seems inside job because how hacker broke the security easily?...
Iam sure not that easy, but yeah this is super huge, it's 3rd largest hack in crypto industry so far. I hope this is the last and will not happen again. Even though all customer funds can be recovered, things like this still show that there are still gaps that can be penetrated. No security is perfect, but all in all there will be better preventive measures in the future
