The U.S. indictments came as the Dutch Defense Ministry said counterintelligence officials broke up a hacking attempt by four Russians last April, as they used sophisticated electronic equipment to try to break into the computers of the Organization for the Prohibition of Chemical Weapons from a parking lot in The Hague. The Dutch said the Russians had a receipt which showed they took a taxi ride from the headquarters of the GRU—Russia’s military intelligence service—to Moscow’s main airport. The four Russians arrived on diplomatic passports; they were later expelled from the Netherlands. Russia has rejected the U.S. indictments and the Dutch allegations, calling them part of a disinformation campaign.
