The FBI is investigating a cyber attack against another U.S. Democratic Party group, which may be related to an earlier hack against the Democratic National Committee, four people familiar with the matter told Reuters. The previously unreported incident at the Democratic Congressional Campaign Committee, or DCCC, and its potential ties to Russian hackers are likely to heighten accusations, so far unproven, that Moscow is trying to meddle in the U.S. presidential election campaign to help Republican nominee Donald Trump. Hacking of the party’s emails caused discord among Democrats at the party’s convention in Philadelphia to nominate Hillary Clinton as its presidential candidate. The newly disclosed breach at the DCCC may have been intended to gather information about donors, rather than to steal money, the sources said on Thursday.
It was not clear what data was exposed, although donors typically submit a variety of personal information including names, email addresses and credit card details when making a contribution. It was also unclear if stolen information was used to hack into other systems.
The DCCC raises money for Democrats running for seats in the U.S. House of Representatives. The intrusion at the group could have begun as recently as June, two of the sources told Reuters.
That was when a bogus website was registered with a name closely resembling that of a main donation site connected to the DCCC. For some time, internet traffic associated with donations that was supposed to go to a company that processes campaign donations instead went to the bogus site, two sources said.
