“If Russia hacked the #DNC, they should be condemned for it,” Snowden wrote on Twitter on Monday, with a link to a 2015 report on the U.S. government’s response to the hacking of Sony Pictures. In that case, he noted, “the FBI presented evidence” for its conclusion that North Korea was responsible for the hacking and subsequent release of internal emails. (The FBI is now investigating the breach of the DNC’s network, which officials told the Daily Beast they first made the committee aware of in April.)
What’s more, Snowden added, the NSA has tools that should make it possible to trace the source of the hack. Even though the Director of National Intelligence usually opposes making such evidence public, he argued, this is a case in which the agency should do so, if only to discourage future attacks.
