The cybersecurity landscape in Uzbekistan has shifted from simple spam campaigns to advanced mobile threats orchestrated by a group called TrickyWonders. Unlike older malware that acted immediately upon installation, current attacks utilize dropper applications such as MidnightDat and RoundRift. These droppers appear legitimate on the surface and can deploy a malicious payload locally even without an internet connection, allowing them to effectively evade initial security screenings.
The primary objective of this operation is financial gain through the theft of one-time passwords and bank card details. Once a user enables the installation of an unknown app and grants the necessary permissions, the malware gains the ability to intercept SMS messages and hide security notifications. This allows the attackers to siphon funds from banking apps and exfiltrate personal information like contact lists and phone numbers.
Distribution of the malware is heavily reliant on deception and hijacked social proof. Attackers use fake Google Play Store pages, fraudulent dating profiles, and Facebook advertisements to lure victims. A particularly effective tactic involves using stolen Telegram sessions to send malicious APK files to a victim's personal contacts, creating a cycle of infection that exploits the trust between friends and family members.

Technically, Wonderland represents a significant upgrade from its predecessors because it features bidirectional command and control communication. This capability transforms the malware from a passive data collector into an active agent that can execute real-time commands and arbitrary requests. The code for both the dropper and the stealer is heavily obfuscated, making it difficult for security researchers to analyze or reverse engineer the software.
Ultimately, the success of these attacks depends on convincing users to sideload applications and bypass standard Android security settings. By presenting fake update screens or masquerading as digital wedding invitations and videos, the attackers trick users into compromising their own devices. This evolution toward more complex, multi-stage delivery systems highlights the increasing sophistication of mobile cybercrime targeting specific regional populations.
