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.

A newly identified Android banking trojan named Rokarolla has been discovered, distributed through malicious websites masquerading as popular applications like TikTok or Google Chrome. The malware targets 217 distinct cryptocurrency and banking applications using 137 sophisticated commands for device control. Capabilities include harvesting lock screen credentials, exfiltrating contact lists and SMS data, deploying keyloggers, blocking calls, creating fraudulent screen overlays, and disabling Google Play Protect. The infection begins with a dropper impersonating Google Play Protect that installs a secondary payload. Rokarolla communicates with C2 infrastructure via HTTPS, uses overlays to steal banking credentials and device unlock patterns, silently monitors WhatsApp contacts, hijacks SMS and calls, manipulates clipboard content for cryptocurrency theft, and employs snapshot-based screen surveillance. It maintains persistence by hiding its icon, muting device audio, and keeping screens active indefinitely.

North Korea-aligned APT group ScarCruft executed a multiplatform supply-chain attack targeting ethnic Koreans in China's Yanbian region, an area significant for North Korean refugees and defectors. Since late 2024, the group compromised a video gaming platform dedicated to Yanbian-themed games, trojanizing both Windows and Android components with the BirdCall backdoor. The Windows client received malicious updates leading to RokRAT and subsequently BirdCall deployment, while Android games were directly trojanized. This marks the first discovery of Android BirdCall, capable of comprehensive surveillance including data collection, screenshots, and voice recording. The campaign focuses on espionage against individuals of interest to the North Korean regime, particularly refugees and defectors.

A new Android Trojan named Datzbro has been discovered targeting seniors through fake Facebook groups promoting travel and social activities. The malware, which combines spyware and banking Trojan capabilities, is distributed via malicious APKs disguised as community apps. Datzbro features remote access, screen sharing, black overlay attacks, and keylogging, allowing attackers to perform financial fraud. It specifically targets banking and crypto-related apps, stealing credentials and sensitive information. The malware's origin appears to be Chinese-speaking developers, and its command-and-control application has been leaked, potentially making it a global threat. The campaign demonstrates the evolving sophistication of mobile threats, blending social engineering with advanced technical capabilities.

A new Android Trojan called PhantomCard is targeting banking customers in Brazil, with potential for global expansion. The malware relays NFC data from victims' banking cards to fraudsters' devices, enabling unauthorized transactions. Distributed through fake 'Google Play' pages as a 'card protection' app, PhantomCard is based on a Chinese-originating NFC relay Malware-as-a-Service. The actor behind it is a known reseller of Android threats in Brazil. PhantomCard's emergence highlights the growing popularity of NFC-based attacks among cybercriminals and the evolving threat landscape, where local threats can reach global markets through reselling schemes.
