Striking gold: Inside the GoldDigger Android malware
Source AlienVault OTX General
Description
GoldDigger is a sophisticated Android banking trojan that primarily targets mobile banking users in South Africa and across Europe, with evidence suggesting plans for global expansion. The malware employs advanced evasion techniques including a custom packer called 'dpt-shell', anti-debugging mechanisms, and Frida detection. It disguises itself as legitimate airline and shopping applications to deceive victims. GoldDigger exploits Android Accessibility services to perform on-device fraud, steal credentials, intercept SMS-based two-factor authentication, and execute unauthorized transactions. A unique feature is its ability to run targeted banking applications in a virtual environment, allowing complete interception of API calls and runtime behavior. The malware maintains communication with command-and-control servers via encrypted WebSocket protocol, enabling capabilities including screen recording, audio capture, phishing overlays, and remote device manipulation.
