An Android Trojan named GoldDigger has been discovered by cybersecurity firm Group-IB, targeting more than 50 financial organizations in Vietnam. The Trojan, which has been active since June, aims to steal banking credentials and has been disguising itself as a false Android application.
GoldDigger initially abuses the Accessibility Service to steal personal information and intercept SMS messages when it is first installed and launched. To avoid detection, the malware impersonates fake websites that look like Google Play Store pages and resembles a Vietnamese government portal and an energy company site.
Group-IB’s analysis revealed that GoldDigger utilizes Virbox Protector, a tool that allows the Trojan to evade detection and makes it difficult to analyze. This use of Virbox by Trojans targeting banking information is becoming increasingly common in the Asia-Pacific region, with two other active Android Trojans following the same approach.
The primary goal of Trojans like GoldDigger is to infect as many devices as possible and gain access to user accounts. Group-IB emphasized that the best way to combat these threats is to implement client-side fraud protection solutions that offer real-time protection, adaptability to evolving threats, and the ability to rely on behavioral indicators to protect customers.
Upon discovering GoldDigger, Group-IB promptly contacted the Vietnam Computer Emergency Response Team to report their findings, sharing technical information and indicators of compromise. The company has also notified its customers about the threat.
Anh Le, Group-IB’s business development manager in Vietnam, stated that although GoldDigger is currently focusing on targets in Vietnam, the malware includes translations in Spanish and traditional Chinese. This suggests that the cybercriminals behind the Trojan may have plans to expand its reach to Spanish and Chinese-speaking countries in the near future.
The discovery of GoldDigger highlights the ongoing threat posed by Android Trojans and the need for robust cybersecurity measures. Financial organizations and users in Vietnam, as well as other countries in the region, should remain vigilant and take steps to protect their devices and sensitive information.
