coinbase was hacked, it's really a pity, the coinbase must immediately fix any shortcomings, so that in the future something like this doesn't happen again, and doesn't disappoint people who have been loyal to storing in coinbase, even though the coinbase is willing to pay compensation, but the coinbase should immediately fix their shortcomings..
Coinbase was not hacked. The coins they had in cold wallets and hot wallets are all safe. Some of the user accounts were hacked, as the criminals exploited a common vulnerability. And as far as I know, the criminals stole coins from other exchange users as well, but they are yet to confirm this. The hackers made use of the SMS account recovery process that is being used in Coinbase. There are several other exchanges that use the same function. Anyway, most of the customers have regained access to their accounts and Coinbase has issued a statement clarifying that it will reimburse the losses (although I don't think that they have the liability to do so).
