• Targeting of online banking platforms, payment gateways, and financial APIs.
• Persistent and stealthy operations aimed at long-term infiltration and data exfiltration.

Defensive Controls

• Regular application security testing, including penetration testing and code reviews.
• Implementation of web application firewalls (WAF) to detect and block malicious traffic.
• Strong authentication mechanisms such as multi-factor authentication (MFA) for user access.
• Continuous monitoring and anomaly detection within financial transaction systems.
• Employee training to recognize and respond to social engineering attempts.
