Mr. Putin has tried repeatedly “to initiate international cooperation in order to jointly counter all forms of cybercrime,” Mr. Peskov added, but the United States has not responded.
American intelligence agencies say that in fact, Russia is a major source of cybercrime and state-directed intrusion into American systems. Investigators have reported that Russian intelligence tried to gain access to American voting systems before the 2016 election, and in some cases succeeded.
Energy power grids have recently turned into an international battlefield. Mr. Trump and Congress gave new authority last year to the American military’s Cyber Command, but two administration officials told The Times that they did not think the president had been told in detail about efforts to penetrate Russia’s energy systems.
Russian foreign policy commentators said that the report about American efforts to insert software code into Russia’s energy system might jeopardize a potential Putin-Trump meeting at the G20 Summit in Japan at the end of June.
“This is a direct challenge that Moscow cannot leave unanswered,” Ruslan Pukhov, an arms expert and head of the Center for Strategies and Technologies, told Kommersant, a Russian business daily.
The two leaders might meet briefly on the sidelines of the summit, Mr. Peskov said, adding that Washington has not reached out to Moscow to organize a full-scale meeting.
