Ars Technica reports:

A joint intelligence bulletin (JIB) has been issued by the Department of Homeland Security and Federal Bureau of Investigation to state and local authorities regarding Russian hacking activities during the 2016 presidential election. While the bulletin contains no new technical information, it is the first official report to confirm that the Russian reconnaissance and hacking efforts in advance of the election went well beyond the 21 states confirmed in previous reports.

As reported by the intelligence newsletter OODA Loop, the JIB stated that, while the FBI and DHS “previously observed suspicious or malicious cyber activity against government networks in 21 states that we assessed was a Russian campaign seeking vulnerabilities and access to election infrastructure,” new information obtained by the agencies “indicates that Russian government cyber actors engaged in research on—as well as direct visits to—election websites and networks in the majority of US states.” While not providing specific details, the bulletin continued, “The FBI and DHS assess that Russian government cyber actors probably conducted research and reconnaissance against all US states’ election networks leading up to the 2016 Presidential elections.”

DHS-FBI JIBs are unclassified documents, but they’re usually marked “FOUO” (for official use only) and are shared through the DHS’ state and major metropolitan Fusion Centers with state and local authorities. The details within the report are mostly well-known. “The information contained in this bulletin is consistent with what we have said publicly and what we have briefed to election officials on multiple occasions,” a DHS spokesperson told Ars. “We assume the Russian government researched and in some cases targeted election infrastructure in all 50 states in an attempt to sow discord and influence the 2016 election.” [Continue reading…]
