The Twitter account of Vitalik Buterin, the co-founder and face of Ethereum, was broken into by hackers on Saturday. They posted a crypto phishing scam in a tweet to Buterin’s nearly 5 million followers containing a link advertising a free NFT drop.

“To celebrate Proto-Danksharding coming to Ethereum, [Consensys] is marking the moment with a commemorative NFT,” the tweet stated. “‘Proto’ honors the work of the devs who made this possible. The collection is free for the next 24 hours. Claim your piece of history.” Putting aside crypto-gobbledygook (Proto-Danksharding is a real thing), the tweet offered followers a free NFT if they clicked the link.
