An Ethereum wallet with an ENS name too crude to publish has amassed millions of dollars over the past week in cryptocurrency and NFTs in what appears to be a sophisticated scam operation. 

Security expert Plumferno first flagged the operation in a thread on X, who said with the help of a few friends she was able to uncover the source of the wallet's stolen crypto: a series of phishing emails purportedly sent from crypto firms BlockFi and FTX, and possibly others, to creditors of the now-bankrupt companies. 

It's possible that the hacker obtained the list of email addresses from data originally stolen from email service Mailer Lite, which was hacked in January, leading to a separate phishing scam that reeled in big bucks, Plumferno said.
