The Russian Milblogger Arrested in Montenegro Is a Kremlin Stalking Horse

Montenegro detained Mikhail Zvinchuk on Oct. 9 with his wife and three other Russian nationals. Authorities later expelled the group, and they flew to Russia. The case matters because Zvinchuk leads Rybar, a large pro-Kremlin military channel involved in wartime information operations.

Prime Minister Milojko Spajić confirmed the detention on X. He cited warnings that Montenegro could face destabilization efforts and hybrid warfare. Zvinchuk is not only a commentator. He has claimed to provide target coordinates to Russia’s Defense Ministry and Wagner, while Rybar has published Ukrainian military positions.

The expulsion shows Montenegro taking a tougher stance toward Russian influence operations. It also highlights the pressure facing a NATO member seeking EU membership by 2028. The article warns that Moscow still has opportunities to exploit Montenegro’s vulnerabilities, despite this action.

Rybar began in 2018 as a channel focused mostly on the Middle East. Mikhail Zvinchuk founded it with Moscow-based programmer Denis Shchukin. Russia’s full-scale invasion of Ukraine in February 2022 transformed Rybar from a modest outlet into a major information warfare platform.

The channel’s Kremlin connections are financial and operational. According to the State Department, late Wagner founder Yevgeny Prigozhin initially funded Rybar. Rostec, Russia’s state defense conglomerate, later funded it. Rybar has also published Ukrainian force positions and claimed the Russian army uses its data for missile strikes.

Zvinchuk’s role goes beyond media work. He has claimed to supply target coordinates to the Defense Ministry and Wagner. Putin appointed him to a group coordinating Russia’s mobilization effort in December 2022. The EU sanctioned him over that role in 2023.

Rybar’s audience exceeds 1.5 million subscribers. That reach expanded sharply after Russia’s full-scale invasion of Ukraine in February 2022. The channel became a major information warfare platform rather than remaining a modest military blog focused mainly on the Middle East.

Its activities extend beyond reporting or commentary. Rybar has published the positions of Ukrainian forces and boasted that the Russian army uses its data for missile strikes. Zvinchuk has also claimed to supply target coordinates to Russia’s Defense Ministry and Wagner. These actions connect its media role with battlefield operations.

Rybar also works internationally. It promotes pro-Kremlin narratives in Africa and the Middle East and has expanded into the Balkans. In Bosnia and Herzegovina, Zvinchuk discussed launching a Rybar media school. Western governments have accused Rybar figures of spreading false narratives and interfering in elections.

Montenegro matters to Russia because it is a potential weak link in NATO’s southeastern flank and a gateway to the Adriatic Sea. Moscow has opposed Montenegro’s Western alignment and EU ambitions since the country joined NATO in 2017.

NATO sees Montenegro as part of its southeastern security position. The country accused Russian operatives of plotting a 2016 coup to prevent its accession to the alliance. NATO later deployed a Counter-Hybrid Support Team there in 2019, showing concern about pressure below the level of open conflict.

The EU views Montenegro as its leading Western Balkan accession candidate. The bloc has reaffirmed support for membership by 2028. That makes Montenegro a test of whether Russian interference can complicate European integration. Its location, alliance membership, and EU ambitions give Moscow strong incentives to apply pressure.

Russian influence operations could make Montenegro’s path toward EU membership more difficult. The country wants to join by 2028 and is the leading accession candidate in the Western Balkans. Destabilization, disinformation, and political pressure could complicate that progress.

The article links these risks to Moscow’s broader campaign against Montenegro’s Western alignment. Russia has challenged the country since it joined NATO in 2017. In 2016, Montenegro accused Russian operatives of plotting a coup to block NATO accession. Rybar’s regional activity adds another channel for influence.

Montenegro’s NATO membership is not described as immediately ending. Instead, the danger is a weaker, more divided ally and a slower EU process. The article calls for renewed NATO support and EU hybrid response teams, following the model used in Moldova. Montenegro’s expulsion of Zvinchuk signals a tougher response.

Russia’s Balkan influence exploits existing ethnic and political divisions. In Bosnia and Herzegovina, Moscow has cultivated close ties with pro-Putin Bosnian Serb politician Milorad Dodik. Dodik has repeatedly threatened Republika Srpska’s secession, leaving the country’s fragile political system vulnerable to outside interference.

Zvinchuk’s activities show how those openings can be used. During a June 2024 visit to Republika Srpska, he discussed plans for a Rybar media school. In November 2025, he reportedly filmed election commentary outside the entity’s government building. At a 2025 festival in Serbia, he called Kosovo and Republika Srpska sensitive pressure points.

These relationships connect identity politics, elections, and pro-Kremlin messaging. Russia can amplify disputes without directly controlling every actor. The article warns that the Balkans remain vulnerable because unresolved divisions and competing territorial claims provide opportunities for influence.

Hybrid warfare is a coordinated effort to weaken a country through several kinds of pressure at once. It can include propaganda, election interference, political pressure, and exploitation of ethnic divisions. The goal is destabilization and reduced trust, not necessarily an immediate military attack.

The article shows how the tools can reinforce one another. Rybar promotes pro-Kremlin narratives and has drawn accusations of election interference. In Bosnia and Herzegovina, Russia cultivates ties with Milorad Dodik, whose secession threats expose ethnic tensions. Media activity can then amplify those disputes and influence how voters understand them.

Together, these methods create state power below the threshold of open war. They can make governments look weak, divide societies, and complicate NATO or EU alignment. Montenegro’s detention of Zvinchuk reflects concern about this combined threat. The article urges NATO and the EU to provide stronger hybrid-response support.
