Hackers target Donald Trump, claim to leak his Social Security number

Hackers describing themselves as part of the Anonymous hacking group claim to have leaked Donald Trump’s personal information, including his Social Security number.

A Twitter account describing itself as devoted to Anonoymous news claimed to leak Trump's information Thursday, tweeting a link to a video blasting the Republican presidential frontrunner. A link to a file sharing site posted with the video purports to reveal Trump’s Social Security number and his addresses,  although the video link says that some of the information has been on the Internet since last year.

However, a prominent Anonymous account, which has 1.61 million followers, later downplayed the claim.  “Seems to be outdated information, take it with a grain of salt,” it tweeted.

Another Twitter account, which describes itself as a voice of the hacking group, also claimed to leak Trump’s personal information via a file sharing site Thursday, including a cellphone number. However, the account was described as "not a credible source" by the prominent Anonymous account, which added that the information is outdated.

The Trump campaign issued a statement saying that authorities have launched an investigation. “The government and law enforcement authorities are seeking the arrest of the people responsible for attempting to illegally hack Mr. Trump’s accounts and telephone information,” it said.

The FBI told FoxNews.com that it is aware of the matter and is working jointly with the U.S. Secret Service.  "Because this is ongoing, we are restricted from commenting further" explained a spokesman, via email.

Hacking collective Anonymous has already declared war on Trump, recently urging hackers to “dismantle” the GOP hopeful’s presidential campaign.
