Regulatory Response and Investigation

During the discussions, which included banks, credit card companies, and other banking regulators, the FSC emphasized the need for institutions to bolster their cybersecurity measures. The regulator's directive for system-wide inspections aims to prevent further data leaks and restore confidence in the security of the country's financial infrastructure.

Authorities have launched an investigation into the incidents to determine the scope of the breaches and identify the perpetrators. The series of attacks highlights the persistent cybersecurity threats facing the global financial industry, placing pressure on institutions to increase investment in security protocols to protect sensitive customer data.
