Mark Cuban, owner of the Dallas Mavericks and billionaire entrepreneur, has lost approximately $870,000 to a crypto scam. Cuban believes he downloaded a tampered version of MetaMask, which allowed scammers to gain access to his wallet and steal his cryptocurrency. The wallet movements were first spotted by pseudonymous on-chain investigator WazzCrypto. Cuban has since moved his remaining funds to Coinbase’s custody. He is one of the few public figures who is personally active in DeFi as an investor.
