The U.S. government has added four commercial spyware operations to the Entity List, severely restricting them from doing business with U.S. firms. The department added Cytrox, a Hungary-based surveillance company, the Greece-based Intellexa, and two related entities in Ireland and North Macedonia. The move is “aimed at improving citizens’ digital security, combating cyber threats, and mitigating unlawful surveillance,” the Commerce Department said. The companies have been accused of supplying spyware that was discovered on the phones of members of the political opposition in various countries.
