Digital rights researchers say two prominent figures linked to Serbia’s anti-government protest movement were targeted with spyware, ahead of crucial parliamentary elections. Balkan media and investigators report that the claims are based on technical findings suggesting compromise by advanced cyberespionage tools, with one report citing “high confidence” in the assessment.

Reuters, via reporting involving one of the men, says the targeting is described in a Citizen Lab report issued Monday. CyberScoop adds that the confirmed and suspected targets include additional public figures, such as a university rector who supports the protests and a prosecutor associated with investigations into a Belgrade development linked to U.S. interests. Across outlets, researchers frame the development as part of a broader pattern in Serbia, where surveillance tools are alleged to have been used against opposition politicians and other groups in the run-up to the election. The reporting focuses on the investigation’s findings rather than any attribution to a specific actor or government body.
