In this blog entry, researchers from the TrendAI™ MDR team discuss how they mapped the full end-to-end operation of SHADOW-WATER-063’s Banana RAT banking malware by analyzing server-side artifacts and victim-side data.

Not every cloud breach starts with malware or a zero-day. In this incident, attackers discovered an exposed Spring Boot Actuator endpoint, harvested credentials from leaked configuration data, then used the OAuth2 Resource Owner Password Credentials (ROPC) flow to authenticate without MFA.

Our analysis of an active KongTuke campaign deploying modeloRAT — malware capable of reconnaissance, command execution, and persistent access — through compromised WordPress sites and fake CAPTCHA lures shows that the group still operates this delivery chain in parallel with the newer CrashFix technique.
