Austria expelled three [1] Russian diplomats from the Russian embassy in Vienna following allegations of espionage.

The move signals a sharpening of tensions between Vienna and Moscow, as the Austrian government takes direct action against suspected intelligence operations on its soil.

Austrian authorities said the diplomats were conducting espionage by installing antennas to intercept data transmitted over satellite internet. The equipment was reportedly located on the roof of the embassy in Vienna [1], [2].

"We have discovered a forest of antennas on the roof of the Russian embassy that were being used to intercept data transmitted over satellite internet," the Austrian Foreign Minister said [1].

The expulsion follows an investigation into the embassy's technical infrastructure. The government determined that the array of antennas was designed specifically to capture communications from satellite-based internet services [2].

Russia has rejected the accusations. A spokesperson for the Russian Embassy in Vienna said, "Austria's decision is outrageous" [1].

The diplomatic fallout occurs as European nations continue to monitor Russian intelligence activities within the European Union. While Austria has historically maintained a complex relationship with Moscow, this expulsion marks a significant breach in diplomatic norms regarding the conduct of embassy staff [2].

“"We have discovered a forest of antennas on the roof of the Russian embassy..."”

This expulsion underscores the increasing friction between EU member states and Russia over hybrid warfare and signals intelligence. By targeting satellite-internet interception, Austria is addressing a specific vulnerability in modern secure communications, suggesting that the embassy was being used as a technical hub for regional surveillance rather than just a diplomatic outpost.
