On social networks, Ramon Abbas flaunts a lavish lifestyle with private jets, designer clothes and luxury cars, leaving him under the radar of the FBI.

On his personal Instagram page, Ray Hushpuppi, with 2.5 million followers, Abbas identifies himself as a real estate developer.

But US federal investigators believe that Abbas had such a lavish lifestyle was actually running a network of hackers, stealing millions of dollars from major companies in the US and Europe.

It was Abbas's wealthy posts that left traces to help the investigating agency uncover his criminal acts.

Over the next few weeks, Abbas will be moved to Los Angeles, facing charges of laundering hundreds of millions of dollars.

Ramon Abbas is a Nigerian national.

Abbas worked with many accomplices and was arrested with 11 others.

"This investigation is aimed at an important link in a large, transnational fraud line," said prosecutor Nick Hanna, who is in charge of investigating the Abbas case in the US.

Abbas does not hide his lavish lifestyle and vast fortune.

"Start your day with sushi at Nobu restaurant in Monte Carlo, Monaco, then decide to hire a helicopter to ... Christian Dior's spa in Paris to do your face and then close the day with champage in Gucci," Abbas posted on.

Abbas regularly photographs expensive cars like Bentley, Ferrari, Mercedes and Rolls Royce alongside the hashtag #AllMine (All are mine).

According to the indictment, US investigators said the lavish photos on social networks posted by Abbas helped them connect information about him.

"The suspects' email accounts also contain email addresses and attachments related to high-value transactions," the indict said.

Abbas's Apple and Snapchat accounts also provided the investigating agency with additional information to identify his identity, along with his address and conversations with other suspects.

The Abbas cyber frauds involve incredible money.

Abbas and his accomplice are believed to have laundered $ 14.7 million in appropriation money from a financial institution last year.

He was also accused of plotting to steal $ 124 million from a football club in the English Premier League.
