How did FTX get hacked?

I'm rather perplexed about the recent hacking incident at FTX. As a cryptocurrency enthusiast, I've always trusted FTX for its secure trading platform. So, I'm really curious to know, how did this happen? Was there a lapse in security measures, or was it a sophisticated attack? And more importantly, what are the steps FTX is taking to ensure such incidents don't recur in the future? I'd appreciate it if you could provide a detailed account of the hack and the subsequent actions taken by FTX.
