Authorities in the Netherlands have arrested the owners of two Dutch companies that allegedly provided bulletproof hosting services to Russian threat actors and evaded sanctions imposed by the European Union.

According to an announcement by the Dutch Fiscal Information and Investigation Service (FIOD), the suspects, a 57-year-old from Amsterdam and a 39-year-old from The Hague, were arrested on May 18.

The investigators conducted searches at three locations in Enschede and Almere, and at two data centers in Dronten and Schiphol-Rijk, and seized laptops, phones, and over 800 servers.

FIOD says the 57-year-old man is the owner and director of a Dutch company that acted as a front for a sanctioned web hosting provider.

The sanctioned entity had been created two weeks before the Russian invasion of Ukraine and facilitated disinformation, interference, and disruptive cyberattacks against members of the EU.
