The hacker or hackers known as Guccifer 2.0 has published several documents purportedly acquired through a late July hack of the Democratic Congressional Campaign Committee. The information includes various shared passwords, internal memos, and personal contact information for Democratic officials and lawmakers.
Guccifer 2.0 also claimed responsibility for a hack of the Democratic National Committee that triggered huge internal turmoil ahead of the Democratic National Convention. Security researchers have linked both hacks to Russian actors, including two known in security circles as COZY BEAR and FANCY BEAR, with links to Russian state intelligence.

Researchers have speculated that the Guccifer 2.0 persona, which has claimed to be a lone actor, is part of a Russian disinformation campaign.
The passwords released appear largely innocuous, mostly subscription accounts to databases, newsletters, and outlets including Lexis Nexis, the New York Times, and Politico.
A much bigger headache is the list of contact information for nearly two hundred Democratic Representatives, officials, and operatives. Much of the information is for offices, schedulers, and other intermediaries, but dozens of records also include personal phone numbers and home addresses. That makes this one of the largest high-profile ‘doxxings,’ or malicious publications of private information, in recent memory.

The dump includes private data for former Democratic National Committee chair Debbie Wasserman Schultz, recently the target of left-wing Democrats’ ire after a previous release of hacked data appeared to show the DNC favoring Hillary Clinton over Bernie Sanders in the primary process. Personal information of several other prominent Democrats, including Charles Rangel, Maxine Waters, and Nancy Pelosi, was not included in the pilfered file.
At press time, the documents were still available online.
