According to new reports, Hillary Clinton’s presidential campaign has been hacked as part of a larger cyber attack against Democratic Party institutions.

The latest hack follows two data breaches involving the Democratic National Committee (DNC) and the Democratic Congressional Campaign Committee (DCCC).

US authorities widely believe that the cyber attacks were committed by agents working for the Russian government.

Some fear that Russia may be trying to influence the presidential election.

However, Russia has denied involvement and denounced the “poisonous anti-Russian” rhetoric coming out of Washington.

According to Hillary Clinton’s campaign, an analytics data program, which it shared with other entities, had been accessed by hackers.

However, there was “no evidence that our internal systems have been compromised”, Hillary Clinton’s press secretary Nick Merrill said on July 29.

The FBI said it was investigating the allegations and the extent of any hacking.

The DNC hacked emails were leaked last week on the eve of the party’s convention in Philadelphia.

The emails showed Democratic Party officials were biased against Bernie Sanders in his primary race against Hillary Clinton.

The hack led to the resignation of the party chairwoman Debbie Wasserman Schultz and sparked protests at the convention.

In addition to the attack on the Clinton campaign, the DCCC was also found to have been compromised.

The DCCC works to raise money for Democratic congressional candidates.

According to a statement issued by the DCCC on July 29, they have hired cyber security company CrowdStrike to help with the investigation.

Hackers may have been able to access the Democrats’ political strategy documents as well as opposition research conducted against Republican candidates.

“We have taken and are continuing to take steps to enhance the security of our network,” the DCCC said.

“We are cooperating with federal law enforcement with respect to their ongoing investigation.”
