What happened?
Attackers used AI models such as Claude and Grok to target more than 400 financial institutions in Latin America. Customer data and account information were compromised as a result.
Why it matters
The case shows that AI models are gaining scale not only on the defense side but also on the attack side. The theft of customer data in sensitive sectors such as banking poses serious risks for both individuals and institutions.
What defenders are doing
Security firms and AI labs have recently been developing tools to detect and block misuse of models. However, details of how attackers used the models remain unclear.
