Russian Doxing Campaign Targets Ukrainian Military with Slovakian Server Support

A coordinated digital warfare effort exposes personal data from military personnel and activists across Europe.

A recent investigation by the Jan Kuciak Center has uncovered a disturbing escalation in Russia’s information warfare: a network of Russian-operated websites is publishing the personal data of Ukrainian military personnel, activists, and political figures across multiple European countries.

These platforms, designed to intimidate, humiliate, and incite harassment, are being hosted on servers based in Slovakia, a NATO and EU member state, Aktuality reported.

Russia-Backed Doxing Sites Leverage Slovakian Infrastructure

According to the report, these doxing websites—many of which function like a malicious “Wikipedia” of personal data—are receiving technical support from Slovakian servers, with particular attention drawn to StormWall, a hosting company registered in Slovakia but owned by Russian nationals.

The affected individuals span not only Ukraine but also public figures and influencers in Poland, Slovakia, the Czech Republic, and Hungary, pointing to a broader regional targeting strategy.

Psychological Warfare: Doxing as a Weapon

This campaign exemplifies a modern form of information and psychological warfare, where exposing the private details of military families, deceased soldiers, or even local officials is used as a tactic to sow fear, create instability, and deter public support for Ukraine.

The leaked data often includes names, home addresses, family relations, and social media activity—all shared publicly with incitements to harass, threaten, or shame the victims.

StormWall’s Alleged Role in Supporting Kremlin Propaganda

Investigators have also established a connection between StormWall and the Kremlin-aligned propaganda platform NewsFront, implying that foreign infrastructure silently facilitates a broader ecosystem of Russian digital operations.

Despite being based within the European Union, the company’s technical support of Russian propaganda and doxing sites may raise serious legal and ethical concerns for Slovakia and the broader EU cybersecurity framework.

Cyberattacks Extend Beyond Ukraine

The scope of this digital offensive extends beyond Ukraine. A recent attack on a Dutch government publishing service, used by municipalities and provinces to release official documents, was claimed by NoName057(16)—a pro-Russian hacker group known for targeting nations that support Ukraine.

Russian hybrid warfare, which targets both physical and digital infrastructures across Europe, is expanding its reach through this cross-border activity.

Time to Strengthen Cyber Defenses Across Borders

This investigation highlights how foreign-owned infrastructure within Europe is being exploited to carry out state-sponsored information warfare. As digital conflict becomes more sophisticated, the line between propaganda and cyberattack continues to blur.

Nations must act swiftly to audit hosting providers, enforce cybersecurity policies, and protect the personal data of those targeted for their support of democracy and international peace.
