Russian President Vladimir Putin has said Russia will not respond to sanctions that President Barack Obama imposed after Russia allegedly launched cyber attacks to help Donald Trump win the U.S. presidential election, The New York Times reported Friday.

Neil MacFarquhar writes Russian foreign minister Sergey Lavrov recommended to expel 35 American diplomats from the country and close a picnic area as well as a warehouse in Moscow to reciprocate U.S. sanctions.

Putin said Russia reserves the “right to take reciprocal measures” and will work with Trump’s administration to restore U.S.-Russia relations, MacFarquhar reported.

The Obama administration declared 35 suspected Russian intelligence operatives as “persona non grata”; announced sanctions on two Russian intelligence services; and penalized four leaders of one of those services called G.R.U.

U.S. intelligence agencies believe G.R.U. received support from the Russian government to launch attacks against the Democratic National Committee and other political organizations in an effort to influence the U.S. presidential election, the report stated.

A Department of Homeland Security report says Russian intelligence services performed spearphishing attacks and other malicious cyber operations called Grizzly Steppe in order to gain access into networks of U.S. government agencies, critical infrastructure, companies and academic institutions.

Todd Breasseale, assistant secretary for public affairs at DHS, said in an executive summary published Friday that Russian cyber threat actors continued to perform spearphishing operations after the U.S. presidential elections in November.

The document also cited that DHS and the FBI also issued a joint analysis report that offers information on the tools that RIS used to hack networks related to the U.S. election.

DHS also listed several questions designed to help organizations assess their networks’ cybersecurity posture, such as queries on risk analysis, vulnerability patching, business continuity, staff training, critical information backups and incident response.

The White House on Thursday imposed sanctions against Russia in relation to its involvement in the U.S. presidential elections through an amended executive order.

The U.S. Secret Service have begun to implement its first cyber and information technology strategic plan that covers agency goals to develop a network operations security center and bolster mobility for special agents and uniformed officers, Signal Magazine reported Sunday.

George Seffers writes Kevin Nally, chief information officer of the Secret Service, finalized the strategy nearly a year ago and currently manages the implementation effort.

Nally crafted the plan as part of efforts to ensure that agency personnel have access to communication and information technology devices as well as mobile equipment to collaborate with the Department of Homeland Security and other federal, state and local law enforcement agencies.

“We’re looking at becoming operating-system agnostic, so the applications we develop in-house can be used on any type of mobile device,” said Nally.

His office also plans to add voice, video and data capacities to the joint operations center and install ultra high frequency trunking system to offer the agency’s uniformed officers with communications services around Washington.

The U.S. Army‘s Rapid Capabilities Office has obtained approval from the service branch to develop a prototype of an electronic warfare in a “phased” manner, Defense News reported Friday.

Jen Judson writes Maj. Gen. Walter Piatt, director of operations at the Army RCO, said the office aims to prototype existing technology that can be put through operational assessment and help the organization develop a long-term rapid prototyping program.

Piatt added the phased approach will use existing Army material to create the prototype within six months and boost training across the chain of command, according to the report.

The report said RCO visited Europe from November to December to explore the EW operational needs of the European theater.

The office seeks to prototype EW technology for limited fielding and operational assessments within a year then run assessments in Europe and U.S., Judson wrote.
