Hillary Clinton appears to have established multiple email addresses for her private use, and possibly the use of her aides, under the domain of “clintonemail.com,” according to a prominent member of the hacking community who supplied independent research data, conducted with high-tech tools, to Fox News.

The hacker used an open-source tool, publicly available, called “The Harvester” to search a variety of data sources – including well-known platforms such as Google, Bing, LinkedIn, Twitter and others – for any stored references to email addresses seen using a particular domain, in this case clintonemail.com. Hackers working under contract for private firms, also known as “White Hat hackers,” routinely use The Harvester during so-called “penetration testing,” or “pen testing,” on behalf of clients trying to ensure that their internal systems are secure.

The application of The Harvester to clintonemail.com revealed additional email addresses besides the one that Clinton aides have insisted publicly that she used, and have said was the only one that she used, when she served as Secretary of State: namely, hdr22@clintonemail.com.

A screen grab of The Harvester’s findings provided to Fox News by the source in the hacker community – whose professional resume also boasts extensive experience in the U.S. intelligence community – lists rather similar, but nonetheless different, email addresses, including hdr@clintonemail.com, hdr18@clintonemail.com, hdr19@clintonemail.com, hdr20@clintonemail.com, and hdr21@clintonemail.com.

Also unearthed by the hacking tool were email addresses of a slightly varied structure, including h.clinton@clintonemail.com, Hillary@clintonemail.com, contact@clintonemail.com, and mau_suit@clintonemail.com.

It’s not known how many of these multiple addresses the secretary herself may have used, nor whether some may have been assigned to close aides entrusted to communicate with her on the clintonemail.com domain.

“Given the sequential similarities to hdr22@ I suspect some others found by my search may also have been used by HRC,” the hacker told Fox News. “I suspect hdr18 -hdr21 may have been used by HRC as well as h@clintonemail.com and hillary@clintonemail.com....I’d also be interested to learn if there were ever hdr1@ thru hdr17@.”

Clinton spokesman Nick Merrill told POLITICO on March 4: “Secretary Clinton used one email account when corresponding with anyone, from Department officials to friends to family.”

However, Rep. Trey Gowdy, R-S.C., chairman of the House select committee investigating the Benghazi terrorist attacks, has issued a statement saying the panel “is in possession of records with two separate and distinct email addresses used by former Secretary Clinton and dated during the time she was secretary of state.”

Contacted by Fox News, neither Merrill nor Philippe Reines, another longtime aide to Clinton who is believed to remain in close contact with her, responded to messages left via telephone and email. Nor did Eric Hothem, the mysterious former Clinton aide who has been identified as having registered the internet server in Chappaqua, New York – the Clintons’ hometown in upstate New York – that hosted the clintonemail.com domain.

“I'm in the process of determining if any of those accounts have been compromised by hackers in the past,” the source told Fox News. “We know that hdr22 has been.”
