SpyMax RAT malware targeting Android devices through wedding invitation scams

How the Scam Works
                 The malware campaign operates through popular messaging platforms such as WhatsApp and Telegram, where attackers share seemingly legitimate digital wedding invitations containing malicious APK files. These deceptive applications masquerade as authentic wedding invite apps, exploiting users’ trust and curiosity about social events to facilitate the installation of compromised software.

                Broadcom researchers have identified this threat as part of their ongoing security monitoring, highlighting the campaign’s sophisticated approach to mobile malware distribution. This attack exemplifies the evolving landscape of mobile threats, where cybercriminals increasingly leverage social contexts and cultural practices to enhance their success rates.

Infection and Data Exfiltration
             Once successfully installed on target devices, the malicious application deploys SpyMax RAT or similar remote access Trojan variants. The malware exhibits advanced stealth capabilities, including the ability to hide its application icon from the device’s interface, making detection by casual users significantly more challenging. The spyware automatically activates during system startup, establishing persistent access to the compromised device.

           The SpyMax RAT deployment follows a multi-stage infection process designed to maximize data collection while minimizing detection. Upon installation, the malware establishes comprehensive surveillance capabilities across multiple device functions, systematically harvesting sensitive information such as SMS messages, contact lists, call logs, keystroke patterns, and one-time passwords used for authentication.

Exfiltration Mechanism
              The exfiltration mechanism employs dual communication channels to ensure reliable data transmission. Primary data transfer occurs through Telegram bot infrastructure, leveraging the platform’s encrypted messaging capabilities to obscure malicious traffic patterns. Additionally, the malware maintains fallback communication with dedicated command-and-control servers, providing redundancy in case primary channels become unavailable or compromised.
