The German Foreign Ministry said it summoned the Russian ambassador, Sergei Nechayev, on Friday over allegations of repeated Russian hybrid attacks on Germany,
DW reports.
Germany has been among several EU countries sounding the alarm in recent years over increasing Russian threats.
Russia called the statements "absurd" and "baseless".
The move to summon Russia's ambassador to Germany followed what officials described as mounting evidence of coordinated Russian activity aimed at undermining Germany's internal stability.
"The goal of these Russian cyber and disinformation attacks is clear: It is to divide society, stir up mistrust, provoke rejection, and weaken confidence in democratic institutions," Foreign Ministry spokesperson Martin Giese said.
Berlin listed some cases that it said were perpetrated by Moscow.
In one instance, Giese said, a cyberattack against Germany's air traffic control authority in August 2024 could be clearly attributed to the Russian hacker group "Fancy Bear."
"Our intelligence findings show that the Russian military intelligence service, the GRU, bears responsibility for this attack," he added, adding that this was now certain.
Giese said Germany was also now certain that Russia attempted to influence the most recent general election.
According to Berlin, this was done through the propagandist group "Storm 1516," which creates and spreads online disinformation to further the interests of the Russian government.
The group, active since 2024, seeks primarily to influence elections in Western countries.
