DHS to Congress: The Russians Are Coming Back

A Department of Homeland Security official on Wednesday told the Senate Intelligence Committee that Russian government-backed hackers targeted as many as 21 states during the 2016 presidential election.

Hackers attempted to penetrate Internet-connected systems related to the elections in up to 21 states, but they were successful only in a small number of them, said Samuel Liles, acting director of the cyber division of the DHS Office of Intelligence and Analysis.
