ShinyHunters claims Santander breach, selling data for 30M customers

ShinyHunters claims to be selling a large stolen dataset allegedly from Banco Santander — containing personal information for customers and employees in Chile, Spain and Uruguay, plus millions of credit card numbers and account records — shortly after Santander disclosed unauthorized access to a third-party hosted database; listings and sample data appeared on multiple hacking forums, though the exact scale and full legitimacy of the data remain partially unverified.
