Cybercrime is taking an alarming turn as social media platforms, particularly Facebook, are now being exploited to target one of the most vulnerable groups: seniors. Recently, researchers uncovered a sophisticated scam campaign using specialized Facebook groups to lure elderly users into installing malicious software on their Android devices under the guise of social activities.
A Global Deception Campaign
What started as a local scam in Australia in August has now escalated into a global concern. Several Facebook groups were flagged for suspicious activities, promoting social events like dance classes, day trips, and community gatherings specially tailored for seniors. Behind this inviting and seemingly harmless facade lay an orchestrated effort to deceive users.
Experts at ThreatFabric, a reputable cybersecurity firm based in the Netherlands, revealed that dozens of such groups exist across Facebook. Interestingly, many of these groups employed AI-generated content to make their offerings appear more authentic and engaging.
Introducing a Global Threat: Datzbro Malware
Though initially confined to Australia, the menace has spread to countries including Singapore, Malaysia, Canada, South Africa, and the United Kingdom. At the heart of this campaign is a malware named Datzbro, posing a significant global threat. The public leaking of its source code has made it accessible to cybercriminals worldwide, further exacerbating the problem.
“Datzbro exploits the trust and community-centric mindset of seniors to gain unauthorized access to their devices,” ThreatFabric noted in their detailed analysis.
Precise Targeting via Trust Manipulation
These attackers showcase a disturbing level of sophistication by focusing on individuals seeking connections through activities. The scam usually begins on Facebook with enticing group posts and then shifts to private messaging platforms like Messenger or WhatsApp. Once engaged, victims are directed to fake registration websites disguised as community event portals.
These fraudulent sites prompt users to install a “community app” for event bookings and updates. However, clicking the “Google Play” button on these sites initiates the installation of Datzbro or Zombinder, a well-known Android dropper capable of bypassing advanced security systems.
Examining Datzbro’s Dangerous Capabilities
Datzbro is no ordinary malware. Its diverse arsenal combines espionage tools such as audio recording, camera access, and file theft with banking Trojan capabilities. This includes remote access, keylogging, and meticulously targeted phishing to steal sensitive information such as banking credentials and cryptocurrency wallets.
For instance, the malware can intercept passwords for platforms like Alipay, China’s most popular mobile payment service, and WeChat, the dominant messaging app in the country. Additionally, it can extract PIN codes and other security credentials from infected devices.
Evidence Points to a Chinese Source
The identity of the group orchestrating this scam remains unconfirmed, but all signs point to developers based in China. The malware’s code base includes Chinese-language strings, further reinforcing this theory. Moreover, similar campaigns have previously targeted Chinese-speaking users, suggesting that Datzbro’s operations began locally before expanding globally.
ThreatFabric highlights a notable trend: the blending of digital espionage and financial attacks, indicating a progression in the tactics of cybercriminal groups.
How to Stay Safe
Given the sophistication of these scams, it’s imperative for seniors and their families to exercise increased caution. Organizations and tech companies must also step up security measures to curb the proliferation of such threats.
