Fox News chief Washington correspondent James Rosen has once again teamed up with a team of hackers to dig deeper into Hillary Clinton’s use of private emails, this time demonstrating that there were multiple security lapses when maintaining her private server.

One of the anonymous hackers, who has “long experience in the U.S. intelligence community,” had previously revealed that Clinton had registered multiple email accounts. The team used legally obtained information about the server to create a virtual replica, and from there, used software to test the entire system for vulnerabilities.

The hackers began by confirming previous Fox News reports that Clinton’s server was located in Manhattan, and was even able to narrow it down to an exact intersection. The extreme ease with which they located the server convinced them that it was likely “highly ‘vulnerable’ to unauthorized intrusion.”

Another problem was that clintonemail.com was run on outdated versions of Microsoft Outlook and Microsoft Internet Information Services (IIS). It would be child’s play for a hacker to look up security vulnerabilities present in the old versions and take advantage of them. The outdated IIS was particularly problematic, sources tell Rosen, since the version Clinton was using had several avenues of attack for hackers to use.

“This is a big deal and just the thing real-world hackers look for in a target and will exploit to the max,” one source said. “Several of these vulnerabilities have been known since 2010 and yet [Clinton] is running official State comms through it.” (VIDEO: ‘The Server Will Remain Private’: Hillary Won’t Allow Oversight Of Emails)

Another hacker told Rosen, “If we learned that the foreign minister of a major foreign country was using her own private server to send and receive emails, and was relying on outdated commercial software to operate and protect it, that’d be a hallelujah moment for us.”
