DeFi have become one of the hottest trends and topics in the space of recent. I knew the rise of DeFi projects will also give rise to hackers and scammers. We saw a similar rise when ICOs were hot and trendy in 2017. The attack on popular DeFi apps is similar to the one we saw on MyEtherWallet in 2018. My advice is to apply extreme caution whenever it comes to anything that poses a thread to account security – I've never been a fan of using private keys in web apps. As Defi becomes more popular, we'll see more attacks like this in the coming months.
Yes it's one of the hottest craze right now, other calling it the catalyst for altcoin bull run so obviously, hackers and cyber actors are going to target it because of the tons of money flowing in this Defi. So it is a must to check everything because once they get your info, (private key and wallet and email), it will be stolen in an instant.
