Summary

In October 2017, days after the banned Catalan independence referendum, Spanish authorities and media reported extensive Russian hybrid influence activities. Spanish Prime Minister Rajoy initially suspected Russian hackers spreading pro-separatist propaganda via automated Twitter bots, with 55% of fake profiles originating from Russia. Later reports by El País revealed that Russian military intelligence agents (GRU) operated on the ground in Catalonia, liaising with radical separatist groups and former Catalan President Carles Puigdemont. Investigations by Spain's highest court were launched against the GRU for these espionage activities. Experts view these operations as part of a broader Kremlin effort to exploit Spain's internal political crisis to destabilize the country and Europe. The reports highlight both cyber influence efforts and human intelligence recruitment as elements of Russia's hybrid tactics in the region.
