A cyber-intelligence company found about 200 files from one of Democratic presidential nominee Hillary Clinton’s closest confidantes on a Romanian server, according to the FBI’s latest release of findings from their investigation into the former secretary of state’s handling of classified materials.

Judicial Watch, the conservative group suing the Department of State over Clinton’s emails, paid an unnamed company $32,000 to conduct a search of the “Deep Web and Dark Web” for data that could have been taken from the private servers of Clinton and adviser Sidney Blumenthal.

Investigators believe Blumenthal was using a private email server since they found about “200 Microsoft Word, Excel and other file types belonging to” Blumenthal on a Romanian server, according to the FBI.

Blumenthal was a senior adviser to President Bill Clinton, and serves as an off-the-books adviser to Hillary Clinton. The FBI found that Blumenthal was keeping touch with Clinton throughout her tenure in the Obama administration, including the sending two dozen emails containing classified information.

One of the main concerns was that Clinton’s use of a private server possibly opened her up to attacks by foreign hackers looking to get access to U.S. intelligence. While there’s no evidence Clinton’s server was successfully hacked, the FBI found an Excel file with an Internet Protocol (IP) linked to Clinton’s private server on a Romanian server.

In reviewing the data, an unnamed investigator found “one sensitive Excel file listing the names of known or suspected jihadists in Libya,” a portion of which was “in Russian,” the FBI reported.

The discovery is the latest FBI release of findings concerning Clinton’s use of a private email server while working in the Obama administration.

FBI Director James Comey called Clinton’s handling of classified materials “extremely careless,” though he said there was no precedent to bring a strong case against her.

“Although we did not find clear evidence that Secretary Clinton or her colleagues intended to violate laws governing the handling of classified information, there is evidence they were extremely careless in their handling of highly classified information,” Comey said in July.
