If you've ever been the victim of an online scam or hack, just know that even tech billionaires and celebrities can fall for fraudalso.

“Shark Tank” star and healthcare entrepreneur Mark Cuban told his X followers over the weekend in a series of now-deleted posts that he fell victim to a scam that locked him out of his Google account.

“Hey @google @sundarpichai. My mcuban@gmail.com just got hacked because someone named Noah at your number 650-203-0000 called and said I had an intruder and tricked (Google's) recovery methods,” Cuban wrote on the platform. . “If anyone receives anything from mcuban@gmail.com after 3:30pm, it's not me.”

Cuban claimed he received four calls in a row from a Google Assistant phone number claiming someone had accessed his account from an unknown device.

Google Assistant is the company's virtual assistant software that uses AI to initiate conversations to complete certain tasks, but the call wasn't coming from Google headquarters itself.

“Somebody was really sophisticated to do that,” Cuban said Dallas Morning tidings. “They found a way to get into one of my Google apps. So my Google account showed me notifications that there was an unknown device using one of my Google apps.”

After finally answering one of the calls, Cuban said the person on the other end walked him through the account recovery process — or so he thought.

It was really so hackers could get into his account.

“They asked me to follow the normal Google process. They literally had the same 3 numbers, etc. And that's how they got my email,” he explained. “They locked me out.”
