The cyber-attacks comes after the vast majority of Catalans voted for independence in a referendum, with the Spanish government working to trigger Article 155 of the country’s constitution in order to abolish autonomy of the region.

The political tension after the Catalonia referendum on October 1, 2017, has influenced the virtual arena as well, resulting in cyber-attacks against Spanish websites carried out by hacktivists leaking information about high profile targets and claiming responsibility for shutting down websites.

“Hacktivist group Anonymous, through associated Twitter accounts, is announcing a massive cyberattack for tomorrow… under the name ‘#OpCatalunya’ and ‘#FreeCatalunya’,” the Department of National Security tweeted.

These threat actors use various anti-Spain hashtags that indicate the different cyber campaigns: #OpEspana, #OpCatalonia, #OpCatalonya and #OpSaveCatalonia.

Since the beginning of October 2017, hacktivists have published various links to download databases belonged to several Spanish websites:
