Microsoft said it had seized fake websites, linked to a Russian military intelligence unit, meant to trick people into thinking they were sites for Republican-leaning think tanks that have criticized President Vladimir V. Putin of Russia. The shift to attacking conservative think tanks underscores the Russian intelligence agency’s goals: to disrupt any institutions challenging Moscow and President Vladimir V. Putin of Russia
The Russian military intelligence unit that sought to influence the 2016 election appears to have a new target: conservative American think tanks that have broken with President Trump and are seeking continued sanctions against Moscow, exposing oligarchs or pressing for human rights.
In a report scheduled for release on Tuesday, Microsoft Corporation said that it detected and seized websites that were created in recent weeks by hackers linked to the Russian unit formerly known as the G.R.U. The sites appeared meant to trick people into thinking they were clicking through links managed by the Hudson Institute and the International Republican Institute, but were secretly redirected to web pages created by the hackers to steal passwords and other credentials.
Microsoft also found websites imitating the United States Senate, but not specific Senate offices or political campaigns.
The shift to attacking conservative think tanks underscores the Russian intelligence agency’s goals: to disrupt any institutions challenging Moscow and President Vladimir V. Putin of Russia.
The Hudson Institute has promoted programs examining the rise of kleptocracy in governments around the world, with Russia as a prime target. The International Republican Institute, which receives some funding from the State Department and the United States Agency for International Development, has worked for decades in promoting democracy around the world.
“We are now seeing another uptick in attacks. What is particular in this instance is the broadening of the type of websites they are going after,” Microsoft’s president, Brad Smith, said Monday in an interview.
“These are organizations that are informally tied to Republicans,” he said, “so we see them broadening beyond the sites they have targeted in the past.”
The International Republican Institute’s board of directors includes several Republican leaders who have been highly critical of Mr. Trump’s interactions with Mr. Putin, including a summit meeting last month between the two leaders in Helsinki, Finland.
