Cuban was alerted to the scam by crypto news outlet DL News and said the hack might have happened after he downloaded a new version of a crypto wallet.

“I’m pretty sure I downloaded a version of MetaMask with some sh*t in it,” Cuban told the news organization.

MetaMask is a popular self-hosted crypto wallet that can be used as an app or browser extension. It is a common ploy for crypto scammers to promote compromised versions of the software that let them access the wallet after a user downloads it.

Cuban said MetaMask crashed on his computer several times before he was alerted to the hack by DL News. He said he quickly locked his NFTs on OpenSea and transferred all the Polygon tokens he had in the hacked account. None of his other crypto wallets were reportedly affected.

“I went on MetaMask for the first time in months. They must have been watching,” he told DL News.

Cuban has been active in the crypto space for years. In years past, he endorsed a DeFI token, Titan, which later fell apart in a crypto bank run in 2021. He was also an advocate for Voyager Digital, a crypto firm that filed for bankruptcy last year.
