U.S. intelligence agencies on Thursday released a detailed report laying out evidence showing that Russia’s government orchestrated cyberattacks meant to tamper with America’s presidential election. The 13-page Joint Analysis Report (JAR), released by the FBI and the Department of Homeland Security (DHS), details the technical methods two Russian intelligence agencies used to “compromise and exploit networks and endpoints associated with the U.S. election, as well as a range of U.S. Government, political, and private sector entities.” The report coincides with the White House announcement that it has ejected 35 Russian intelligence diplomats and imposed sanctions on nine Russian officials or entities.
The Obama administration imposed sanctions on four officers of the Russian military intelligence agency—the Main Intelligence Directorate, or GRU—whom the U.S. believes orchestrated cyberattacks against the Democratic National Committee (DNC) and John Podesta, former campaign manager for Democratic nominee Hillary Clinton. The U.S. has also sanctioned the GRU itself, as well as Russia’s civilian intelligence agency, the Federal Security Service, or FSB. The U.S. also imposed sanctions on three companies the White House says aided GRU’s cyberattacks.
U.S. intelligence dubbed the Russian cyber campaign “Grizzly Steppe” in its report, which repeatedly refers to the attacks on the DNC and Podesta but does not mention them by name.
