The DNC breach occurred around the same time as breaches of U.S. government systems at the State Department and the White House. Analysts from the National Security Agency found signatures in those breaches that led them to suspect there were other intrusions outside the government, including at the DNC...
..."I talked to the general counsel of the DNC today and he assures me that every step along the way when we were notified of these issues that we changed systems, changed procedures," said DNC vice chairwoman Donna Brazile to CNN's Wolf Blitzer. "But these hackers are so sophisticated that they changed procedures. So yes, it went on for more than a year, but at no time did we ignore the warning from the FBI or any other federal officials."
The FBI and other U.S. agencies involved haven't yet officially attributed the DNC attack to Russian government hackers. But evidence gathered by the FBI so far points to groups that are known to U.S. counter-intelligence for carrying out intrusions for the Russian government, the officials briefed on the probe say.
