Billionaire investor Mark Cuban claims he lost access to his Gmail account after falling victim to a hoax call, just months after over $800,000 was drained from his cryptocurrency wallet.

“I just got hacked at my mcuban@gmail.com because someone named Noah at your 650-203-0000 called and said I had an intruder and spoofed Google's recovery methods,” Cuban wrote in a June 22 X post. This is usually done by tricking users into revealing personal information or account credentials by posing as an official employee, in this case, Google.

“If anyone gets anything from mcuban@gmail.com after 3:30pm pst it’s not me,” Cuban informed his 8.8 million X followers.

While he received supportive messages from the crypto community, others speculated about the number of emails he was going to miss during the period of not having any access.

“When you get your access back, please post a screenshot of the number of unread emails. I’m betting it is up to 5 digits by now,” crypto exchange Kraken chief security officer Nick Percoco wrote in a June 22 X post. Some even questioned whether his X account was also compromised.

“Is it POSSIBLE that his X account has now been hacked also by the hackers? Therefore they’re trying to get more information,” a user who goes by the name “Mickamious” added.

Cuban's crypto wallet drained in recent incident

This comes just nine months after Cuban's hot wallet was drained of approximately $870,000, possibly by hackers who had been waiting for him to log into MetaMask for the first time in months.

In September 2023, Cointelegraph reported that independent blockchain sleuth Wazz was the first to spot the hack after they highlighted suspicious behavior with one of Cuban’s wallets that the 65-year-old hadn’t interacted with for roughly five months.

Meanwhile, Cuban has been a vocal crypto advocate in recent times, especially in pushing for more favorable crypto regulations in the United States.

Most recently, Cuban pushed for the U.S. Commodity Futures Trading Commission (CFTC) to regulate “all crypto,” as opposed to the U.S. Securities and Exchange Commission (SEC), due to the SEC's regulation-by-enforcement approach to the crypto industry.
