Guccifer 2.0 a hacker believed to be tied to the Russian intelligence services has published more records stolen as part of the DNC breach
A hacker made public another set of internal Democratic Party papers, including the personal cellphone numbers and email addresses of nearly 200 lawmakers. The hacker claiming responsibility for the breach is working under the pseudonym Guccifer 2.0, which American intelligence officials believe is an alias for a Russian intelligence hacker. The hacker appeared eager to taunt Democrats in releasing the latest files. Those documents came from the Democratic Congressional Campaign Committee, the fund-raising arm for House Democrats.

The files appeared to be less politically embarrassing and damaging than Guccifer 2.0 initial trove, which came from the Democratic National Committee. Those documents, released by WikiLeaks last month on the eve of the party’s convention, led to the resignation of the committee’s leader, Representative Debbie Wasserman Schultz.
“It’s time for new revelations now,” the Guccifer 2.0 wrote in posting the files. “All of you may have heard about the DCCC hack. As you see I wasn’t wasting my time! It was even easier than in the case of the DNC breach.”
Guccifer 2.0 indicated that more leaks would follow, writing on Twitter that “the major trove” of the House committee documents would be sent to WikiLeaks. “Keep following,” he or she suggest.
While it became known last month that the House committee had been hacked along with the D.N.C., this was the first time its files had become public. In a statement, the House committee said it was investigating the authenticity of the documents and was working with federal law enforcement officials. The F.B.I. is leading the investigation.
American intelligence officials said they are virtually certain that Russian intelligence officials were behind the attack. They said that the breach appears to have extended beyond the two Democratic groups to include the personal email accounts of at least 100 Democratic officials.
The D.N.C. documents that were released last month proved intensely embarrassing for committee officials because they contained emails indicating that party leaders favored Hillary Clinton as their nominee over her rival, Senator Bernie Sanders of Vermont. The committee’s interim leader, Donna Brazile, created a special cybersecurity panel this week to guard against future attacks.
The American authorities remain uncertain whether the electronic break-in to the Democrats’ computer systems was intended as fairly routine cyberespionage or as part of an effort to manipulate the presidential election. The Republican nominee, Donald J. Trump, urged the Russians last month to try to find 33,000 “missing” emails from Mrs. Clinton’s personal server. But after his remark produced an intense backlash, Mr. Trump said later that he was being sarcastic.
