Zimperium’s Zero-Day Detection of Android Malware Using .NET MAUI Framework

A recent report by McAfee disclosed a new Android malware campaign leveraging the .NET MAUI cross-platform framework to evade detection. This technique enables attackers to write malicious code that runs seamlessly across different operating systems while posing unique challenges that render traditional detection methods less effective. The malware can disguise itself as a legitimate application while harvesting sensitive data, executing commands remotely, and establishing persistent backdoors on compromised devices. 

Of the 15 malware samples reported, Zimperium’s Mobile Threat Defense (MTD) detected 13 in a zero-day fashion, showcasing the strength of our on-device dynamic detection  capabilities. Unlike conventional security solutions that rely on heuristics, Zimperium continuously monitors behavior, allowing us to detect emerging threats in real time, even when attackers attempt to obfuscate their payloads.

As mobile threats continue to evolve, adversaries are adopting cross-platform frameworks to be stealthy. Zimperium remains committed to detecting and mitigating these threats in real-time, ensuring comprehensive protection for mobile users.
