A computer service used by the Clinton campaign was hit as part of the Democratic National Committee hack, the campaign has confirmed. Campaign officials say the hackers had access to a voter database program for around five days, but there is no sign that the campaign's own systems were breached, reports Reuters. It's not clear exactly what material was taken, though officials say information like voters' credit card numbers was not involved. "An analytics data program maintained by the DNC, and used by our campaign and a number of other entities, was accessed as part of the DNC hack," said Clinton campaign spokesman Nick Merrill, per CNN. "Our campaign computer system has been under review by outside cyber security experts. To date, they have found no evidence that our internal systems have been compromised."
The Democratic Congressional Campaign Committee, the official fundraising committee for House Democrats, confirmed on Friday that it has also been hacked. Intelligence officials and cybersecurity experts believe the hackers were almost certainly from Russia's GRU intelligence agency. The FBI says it is "aware of media reporting on cyber intrusions involving multiple political entities, and is working to determine the accuracy, nature, and scope of these matters," the Chicago Tribune reports. Law enforcement sources tell the Washington Post that Russian government hackers have also targeted the Republican National Committee and the Trump campaign, though it's not clear whether they succeeded. (Trump says he was being sarcastic when he urged Russia to unearth Clinton's emails.)
