The hacker known as Guccifer 2.0 on Tuesday released a new trove of documents purportedly stolen from the Democratic National Committee (DNC).

The dump is more than 600 megabytes of information, but various reviews of the documents have yet to turn up any bombshells.

The cache, if authentic, is primarily composed of information on Democratic donors, fundraising efforts and donor outreach. It also contains some years-old documents compiled for then-Virginia governor and DNC chair Tim Kaine Timothy (Tim) Michael KaineTrump meets with potential Supreme Court pick Amy Coney Barrett at White House Names to watch as Trump picks Ginsburg replacement on Supreme Court Barrett seen as a front-runner for Trump Supreme Court pick MORE, who is now Hillary Clinton Hillary Diane Rodham ClintonJoe Biden looks to expand election battleground into Trump country Biden leads Trump by 12 points among Catholic voters: poll The Hill's Campaign Report: Biden goes on offense MORE’s running mate.

Guccifer 2.0, who has claimed credit for the DNC hack, is widely thought to be a front for Russian intelligence agencies.

Although he has claimed to be Romanian, tools used in the attack were matched to Russian intelligence agencies and, when tested, Guccifer 2.0 has struggled to speak in Romanian.

Experts have also questioned whether Guccifer 2.0 is even a single person.

He has continued to release stolen DNC pages in fits and spurts — including some released to The Hill — since the original cache was published by WikiLeaks on the eve of the Democratic National Convention in July.

But none have had the impact of that release, which is widely speculated to have been an effort by the Russian government to influence the outcome of the U.S. election by damaging Clinton.

The stolen documents revealed that the DNC had attempted to help Clinton's campaign at the expense of Sen.

They led to the resignation of multiple party officials, including DNC chair Debbie Wasserman Schultz.

The DNC on Tuesday said that it was the victim of "an illegal cyberattack by Russian state-sponsored agents who seek to harm the Democratic party ... in an effort to influence the presidential election."

"We have been anticipating than additional batch of documents talent by Russian agents would be released. Our legal team is now int he process of reviewing these private documents, and attempting to confirm their authenticity, as it is common for Russian hackers to forge documents," Interim DNC Chair Donna Brazile said in a statement.

"We would urge anyone attempting to access these documents to proceed with extreme caution given the potential malware risks."
