A suspected Russian hacker has leaked the email addresses and cell phone numbers of almost every Democrat in the House of Representatives - along with the message claiming the presidential election is being 'settled behind the scenes.'

It's the latest cyber-attack on the Democratic party since WikiLeaks published tens of thousands of hacked emails from inside the DNC and Russian hackers apparently broke into the computers of the Hillary Clinton campaign.

Top Democrats have claimed that Russian intelligence is behind the cyber-attacks as part of an attempt to influence the election.

Documents released appear to include information from U.S. House Democratic Leader Nancy Pelosi's computer.

On Thursday, Pelosi had said that the recent cyber attack on Democratic politicians was 'broad' and that Russians were clearly behind the breach.

'It is the Russians,' Pelosi told reporters at a news conference.

Pelosi called the attack, made public last month, an 'electronic Watergate' akin to the 1972 burglary at Democratic Party headquarters at the Watergate office that upended the Nixon presidency. 'This is a break-in.'

In a post on his blog, a hacker known as 'Guccifer 2.0' posted an Excel spreadsheet that contains contact information for hundreds of Democrats as well as congressional staff members and campaign personnel.

Investigators concluded that the hacker, who claims to be Romanian, is part of a Romanian intelligence operation.

He also uploaded documents that include account names and passwords for a number of subscription services used by the Democratic Congressional Campaign Committee.

In a message posted on Friday, he said: 'As you see the U.S. presidential elections are becoming a farce, a big political performance where the voters are far from playing the leading role.

'Everything is being settled behind the scenes as it was with Bernie Sanders.

'I wonder what happened to the true democracy, to the equal opportunities, the things we love the United States for.'

The hacker also urged reporters to contact him through direct messages on Twitter.

'Dear journalists, you may send me a DM if you're interested in exclusive materials from the DCCC, which I have plenty of,' he wrote.

'Guccifer 2.0' also claimed the information stolen from the DCCC was 'even easier' to hack than more than 19,000 emails he hacked from the DNC and provided to WikiLeaks.

The hacked emails exposed an apparent lack of neutrality in the primary race between Clinton and Bernie Sanders, with some party officials disparaging Sanders.

It led to the resignation of party chairwoman Debbie Wasserman Schultz on the the eve of the party's presidential nominating convention in Philadelphia in July.

Since then, CEO Amy Dacey, chief finance officer Brad Marshall and communications director Luis Miranda have also left their jobs.

Marshall wrote the most explosive email, questioning Sanders' Jewish faith and suggesting he could be portrayed as an atheist. He has apologized for the missive.

Democratic Party officials learned in late April that their systems had been attacked after they discovered malicious software on their computers.

A cybersecurity firm they employed found traces of at least two sophisticated hacking groups on the Democrats' network - both of which have ties to the Russian government.

Late July, a computer service used by Clinton's campaign was hacked as part of a broader breach of the DNC.

The breach affected a DNC data analytics program used by the campaign and a number of other organizations, according to the Clinton campaign.

For about five days the hackers had access to the program, which is used to conduct voter analysis. It did not include Social Security numbers of credit card information, according to a campaign aide.
