Russia has transformed the rooftops of its sprawling diplomatic premises in Vienna into the Kremlin's largest covert signals intelligence platform in the West, a Financial Times investigation has revealed. Clusters of satellite dishes - none of them pointing east toward Moscow - have been actively targeting NATO government and military communications, western security officials said.
"It's one of our main concerns about Russian activity here. We know they have been targeting Nato government and military communications," a senior European diplomat based in Vienna told the Financial Times, as "Hvylya" reports. "Vienna has really taken on a lot of importance for them - it's their hub in Europe."
The scale of Russia's intelligence operation in Vienna has grown significantly since the 2022 full-scale invasion of Ukraine. While most European countries expelled Russian diplomats in response, neutral Austria took a far more permissive approach toward Moscow's outposts, allowing the network to expand largely unchecked.
Western intelligence officials in Vienna said they had monitored the installation of several new dishes and other unusual equipment on rooftops over the past two years. The frequency with which some dishes are being repositioned indicates they are "very actively used to target multiple satellites," one official said, noting that dishes used merely for embassy communications back to Moscow would not need to be moved.
Even Austria's own domestic intelligence agency, the DSN, has acknowledged the threat, warning that "the technical capabilities and adaptable alignment of the Russian Federation's SIGINT stations pose a significant security risk in counter-espionage." Russia still maintains roughly 500 diplomatic staff in the city, with as many as a third suspected of covertly working as spies, according to Austrian intelligence assessments.
From Vienna, Russia is intercepting not only European communications but also those in the Middle East and Africa, the investigation found. The Austrian capital's position - just over 100 kilometers from one of Europe's main satellite communication stations in Aflenz, and home to UN agencies, the OSCE, the IAEA, and OPEC - makes it an optimal base for such operations.
