The actions are expected to include expanded sanctions and diplomatic measures, the officials said, in what the administration deems a proportional response to a Russian operation that went beyond cyber hacking activities common among nations, CNN reports.
Some of the steps are expected to name individuals associated with a Russian disinformation campaign that US intelligence officials say used hacked information from mostly Democratic Party organizations and officials to attack the Hillary Clinton presidential campaign.
US officials have also said the federal government plans some unannounced actions taken through covert means at a time of its choosing.
The retaliatory measures are separate from an intelligence report President Barack Obama ordered on foreign hacking of US election entities. That report expected in early January will include declassified intelligence information on cyber hacks by China in 2008 and 2012, as well as the hacking and disinformation activities by Russian intelligence agencies in the 2016 campaign, the officials said.
The administration’s announcement comes after months of internal debate over how to respond to Russian cyber activity that US law enforcement and intelligence agencies have watched take place for over a year.
In recent months, Obama administration officials focused on protecting voting machines and preventing hackers from affecting the balloting. Officials were relieved when the November 8 elections were completed without tampering of votes.
But the damage had already been done.
US intelligence officials believe that the Russian efforts were intended to hurt Clinton’s campaign. At a minimum the Russians expected the operation to sow confusion into the US elections. Then as they saw it having some success, the Russian intelligence agencies redoubled their efforts by funneling releases of hacked information to sites such as WikiLeaks and DCLeaks, intelligence officials believe.
