Spanish Authorities Dismantle Crime Ring Connected to Phishing Operation

Spain’s National Police arrested two threat actors and 15 members of a cybercriminal organization, and 23 individuals involved in illegal financial operations and bank scams.

The threat actors were engaged in an email and SMS-based phishing campaign and scammed nearly 300,000 individuals making away with €700,000 ($768,000).
