Intelligence dump from DHS and FBI bolsters claims of Russian election interference.

In an executive order issued today, President Barack Obama used his emergency powers to impose sanctions on a number of Russian military and intelligence officials and also to eject 35 Russians labeled by the administration as intelligence operatives. The order was issued as a response to the breach of the Democratic National Committee's network and the targeted intrusion into e-mail accounts belonging to members of Hillary Clinton's presidential campaign.

Obama made the sanctions an extension of an April 2015 executive order "to take additional steps to deal with the national emergency with respect to significant malicious cyber-enabled activities."

The order is being accompanied by the publication of data from US intelligence communities bolstering findings that the breaches were part of an information operation to manipulate the results of the US presidential election. The data, released by the Department of Homeland Security and Federal Bureau of Investigation as a Joint Analysis Report (JAR), contains "declassified technical information on Russian civilian and military intelligence services’ malicious cyber activity, to better help network defenders in the United States and abroad identify, detect, and disrupt Russia’s global campaign of malicious cyber activities," according to an Obama administration statement. "The JAR includes information on computers around the world that Russian intelligence services have co-opted without the knowledge of their owners in order to conduct their malicious activity in a way that makes it difficult to trace back to Russia." Some of the data had been previously published by cyber-security firms, but in some cases the data is newly declassified government data.

The JAR (full text available here) includes information that will allow security firms and companies to identify and block malware used by Russian intelligence services, along with a breakdown of the Russian malware operators' standard methods and tactics. DHS has added these "indicators of compromise" to their Automated Indicator Sharing service.

The executive order singles out the GRU (Russia's Main Intelligence Directorate), the FSB (Federal Security Service, the successor to the KGB), Esage Lab (a Web development arm of the Russian information security company Zorsecurity), the St. Petersburg-based firm Special Technology Center, and Russia's Professional Association of Designers of Data Processing Systems. It also names four individuals: GRU chief General-Lieutenant Igor Korobov, GRU Deputy Chief and Head of Signals Intelligence Sergey Aleksandrovich Gizunov, and GRU First Deputy Chiefs Igor Olegovich Kostyukov and Vladimir Stepanovich Alexseyev.

The 35 Russians ejected from the US—individuals identified as intelligence operatives working out of the Russian embassy in Washington and Russia's consulate in San Francisco—were ejected not in response to the DNC and Clinton campaign hacks, but in response to "harassment of our diplomatic personnel in Russia by security personnel and police," according to a White House fact sheet issued on the executive order.

In addition to those explicitly named by the order, Obama's order applies to:

…any person determined by the Secretary of the Treasury, in consultation with the Attorney General and the Secretary of State, to be responsible for or complicit in, or to have engaged in, directly or indirectly, cyberenabled activities originating from, or directed by persons located, in whole or in substantial part, outside the United States that are reasonably likely to result in, or have materially contributed to, a significant threat to the national security, foreign policy, or economic health or financial stability of the United States and that have the purpose or effect of … tampering with, altering, or causing a misappropriation of information with the purpose or effect of interfering with or undermining election processes or institutions.
That could, if pressed aggressively, apply to a very large swath of individuals, including operators of "fake news" sites and others involved tangentially in the distribution of information that may be seen as intended to interfere with elections—including the still-unidentified individuals involved in hacking two state election commission websites. But many of the organizations in Russia that might fall under this banner are already under US sanctions.

Just how aggressively these measures will be pressed will be left largely to the incoming Trump administration. President-elect Trump will find himself in a position of having to outright dismiss the evidence presented by the FBI and DHS in order to rescind the sanctions entirely. But Trump has already shrugged off "the cyber" on several occasions during the transition. On December 28, Trump responded to a question about possible sanctions over the hacking:

I think we ought to get on with our lives. I think that computers have complicated lives very greatly. The whole age of computer has made it where nobody knows exactly what is going on. We have speed, we have a lot of other things, but I’m not sure we have the kind, the security we need.
