While Binance puts the blame to a third party company. I will learn and know more about this hot issue.
Binance can fabricate a story of their own, it's their business at risk here so they'll have to come up with a good explanation that will make traders not to panic and withdraw their funds. Until I hear some report coming from an independent investigator that has a good reputation, I would not believe any story that would come out.
A truly independent third party investigator should make an honest-to-goodness audit report, and not just a garbage report that is done with a price just to pacify the traders.
All centralized exchanges will fall to hackers, it just depends on time. Hackers are getting really good, and possibly even better then exchange's security, and they'll always find a way. This is why DEX's are the only real way to trade successfully, but due to rules and regulations, it's making it very hard to advance DEXs.
