Cybersecurity researchers have identified a new Android banking trojan named Datzbro, which is being used in targeted campaigns against elderly individuals. The Datzbro malware is distributed through fake Facebook groups that promote social activities and travel events specifically aimed at seniors. These groups use artificial intelligence-generated content to appear legitimate and attract elderly users seeking companionship and activities. Once a target expresses interest in an event, scammers contact them via Facebook Messenger or WhatsApp, urging them to download a malicious APK file from fraudulent websites such as 'download.seniorgroupapps[.]com.' The websites claim to offer a community application for event registration and member interaction, but in reality, they deliver the Datzbro trojan. The campaign was first detected in August 2025 by ThreatFabric after reports from Australian users, but it has also targeted individuals in Singapore, Malaysia, Canada, South Africa, and the U.K. The attackers have designed their infrastructure to potentially target both Android and iOS users, with placeholder links for iOS TestFlight apps, indicating a broader intent. On Android devices, the malware is sometimes delivered directly or via a dropper created with the Zombinder APK binding service, which helps bypass security restrictions on newer Android versions. Once installed, Datzbro can perform device takeover attacks, allowing threat actors to conduct fraudulent banking transactions and steal sensitive information. The malware is capable of hijacking devices, granting attackers extensive control and access to personal and financial data. The campaign's focus on the elderly makes it particularly concerning, as this demographic is often less familiar with mobile security best practices. The use of AI-generated content and social engineering tactics increases the likelihood of successful infections. Security experts warn that the campaign is ongoing and evolving, with attackers refining their methods to evade detection and expand their reach. The discovery of placeholder iOS links suggests that future campaigns may also target Apple device users. Researchers recommend heightened vigilance for seniors participating in online communities and urge the implementation of robust mobile security solutions. The incident highlights the growing sophistication of social engineering attacks leveraging popular platforms like Facebook to distribute malware. Law enforcement and cybersecurity organizations are monitoring the situation and advising potential victims to avoid downloading applications from unofficial sources. The Datzbro campaign underscores the need for increased awareness and education around mobile threats, especially among vulnerable populations.
