people must stop using web wallets and start searching for safe alternative because there is no website is safe from being hacked and I am sure blockchain will not compensate any one got hacked in this attack if there is any
The website may get hacked but not necessarily the hackers will have access to any of the data since to best of knowledge I know they don't store any private keys on their servers.Unless you've not backed up your private keys,you should be worried.Web wallets are much more reliable for daily small amount of transactions if you're lazy to open up the desktop app for every second minute.
