New malware targeting android users exploits Cross-Platform framework for evasion

A new wave of Android malware is exploiting Microsoft’s .NET MAUI framework to evade detection and steal sensitive data. Disguised as banking and social media apps, this malware tricks users into installing fake applications, harvesting their personal information, and sending it to cybercriminals.

  •  Malware is spread through phishing links and unofficial app stores.
  •  Fake banking apps targeting Indian users and counterfeit social media apps for Chinese-speaking users.
  •  Attackers use .NET MAUI’s cross-platform capabilities to hide malicious code in blob files.
  •  Multi-stage loading techniques help the malware avoid antivirus detection.
  •  Data theft includes banking credentials, personal details, and contact information.
  •  Uses encrypted socket communication to bypass network monitoring.

How the Attack Works

  • Cybercriminals distribute fake apps through unofficial websites and messaging groups. Users are tricked into downloading malicious versions of banking apps (like IndusInd Bank) or social media platforms (like X, formerly Twitter).
  • Once installed, these fake apps prompt users to enter personal information, which is then transmitted to hacker-controlled servers.

Advanced Evasion Techniques

  • Hiding Malicious Code: Unlike traditional malware, which stores harmful code in Java or native libraries, this malware conceals its functions inside blob binary files, making it invisible to standard antivirus tools.
  • Multi-Stage Execution: The malware loads in three steps, decrypting and executing malicious components gradually to avoid detection.
  • Permission Manipulation: It modifies the AndroidManifest.xml file, requesting excessive permissions to confuse security analysis tools.
  • Encrypted Communication: Instead of using regular HTTP traffic, it communicates with command-and-control servers via encrypted sockets, making detection harder.

To Protect Yourself

  •  Download apps only from official stores like Google Play.
  •  Avoid clicking on unknown links from messages or social media.
  •  Verify app permissions before installation.
  •  Enable Play Protect on Android devices for added security.
  •  Regularly update your device and security software.

This new Android malware campaign highlights how cybercriminals are constantly evolving their tactics. By exploiting cross-platform frameworks like .NET MAUI, attackers can bypass traditional security measures and launch highly effective phishing campaigns. Stay vigilant, avoid unofficial app sources, and always verify an app’s authenticity before downloading.
