Verified (fact)

Security startup Straiker analyzed internal operating materials and attack records of the hacking group CyberCartel and said the group combined several commercial AI models, including Claude and Grok, to attack about 400 financial institutions in Latin America. According to reports, AI agents handled target reconnaissance, attack planning and execution, stealing passwords and customer data to access bank accounts.
