Two separate groups of Russian hackers have reportedly had their way with the Democratic National Committee's network [npr.org] for months... up until last weekend:
Russian hackers have been accessing the Democratic National Committee's computer network for the past year, and have stolen information including opposition research files on presumptive Republican presidential nominee Donald Trump.
According to CrowdStrike, the security firm the DNC called in to deal with the massive data breach, one group of hackers tied to the Russian government has been stealing information from the national party for about a year. "They infiltrated the DNC's network last summer and were monitoring their communications, their email servers, and the like," company co-founder Dmitri Alperovitch told NPR.
A second group, also tied to Russia, accessed the DNC's network in April. "They went straight for the research department of the DNC and exfiltrated opposition materials on Mr. Trump," Alperovitch said.
The Washington Post first reported [washingtonpost.com] the DNC break-in.
CrowdStrike doesn't believe the two distinct groups of Russian hackers — which the company has internally nicknamed COZY BEAR and FANCY BEAR — collaborated with each other. "Instead," company co-founder Dmitri Alperovitch wrote in a lengthy blog post [crowdstrike.com], "we observed the two Russian espionage groups compromise the same systems and engage separately in the theft of identical credentials."
