Billionaire Mark Cuban fell victim to a recent hot wallet hack, resulting in the loss of nearly $870,000 from his MetaMask wallet. The hack was initially detected by independent blockchain investigator @WazzCrypto, who noticed unusual activity in one of Cuban’s dormant wallets.

Within a 10-minute timeframe, various assets were rapidly withdrawn from the wallet, including USD Coin (USDC), Tether (USDT), and Lido Staked Ether (stETH). An additional $2 million worth of USDC was later transferred to another wallet, raising suspicions of asset transfers within Cuban’s portfolio.

Mark Cuban confirmed the theft, stating that he logged into MetaMask after several months and suspected that someone had been monitoring his actions. He initially believed he had been hacked for 5 Ether but later discovered losses totaling approximately $870,000 across 10 different cryptocurrencies.

Cuban attributed the hack to downloading a compromised version of MetaMask, which caused crashes and prompted him to secure his NFTs on OpenSea and transfer his Polygon assets.

Cuban clarified that only the compromised account was affected, and he successfully moved the remaining assets to Coinbase using authentication dongles. He expressed a belief that 99% of crypto tokens will eventually fail.
