A website which posted what appears to be financial information on celebrities, including the US First Lady, is being investigated by the FBI and US Secret Services.
The website claims to have also published Michelle Obama’s social security number.
Vice President Joe Biden was another victim, along with the director of the FBI Robert Mueller and singer Beyonce. Arnold Schwartzenegger, Britney Spears and property tycoon Donald Trump were also among the 17 high profile figures targeted by the people who set up the website.
Authorities are probing whether it could have been the work of Russian hackers as the website used the suffix for the former Soviet Union – .su.
The website has been viewed by more than 200,000 people.
