A host of high-profile politicians, public figures and celebrities have had their personal details stolen, a hacking group has claimed.

Michelle Obama, the first lady, is the latest to be added to the list on Exposed.su, which also includes rap star Jay-Z, vice president of the US Joe Biden, former secretary of state Hilary Clinton and FBI director Robert Mueller. Actors Ashton Kutcher and Mel Gibson also had data supposedly related to them posted online.

Hacking hits celebs

Posted data includes social security numbers, credit reports and addresses of those targeted. The hackers are using a .su domain, which relates to nations of the former USSR, but is no longer widely used. The group has also set up a Twitter account, posting in Russian.

It has also posted the following epigram on both sites: “If you believe that God makes miracles, you have to wonder if Satan has a few up his sleeve.”

The press office for the secretary of state had not responded to a request for comment at the time of publication.

But the Los Angeles Police Department has said it is investigating how personal data got onto the Exposed.su site, which it describes as “creepy”.  The FBI said it was aware of the site, but it has not confirmed whether any investigation is underway.

TechWeekEurope’s trip to the site revealed that some of the links were not working, indicating some of the data has been removed, including those related to Clinton and Biden. The information purportedly relating to Michelle Obama remains online.

The visit also revealed content delivery network CloudFlare was supporting Exposed.su, presumably to offer protection against distributed denial of service (DDoS) attacks. The company has an open-to-anyone policy and will only cut off customers if asked to do so by a court.

TechWeekEurope asked Matthew Prince, CEO of CloudFlare, to comment on the matter, but at the time of publication he had not responded.
