Android Users Beware: Necro Malware Infects Millions Through Spotify, WhatsApp Modded Apps

A sophisticated Android malware known as Necro has emerged as a significant threat, affecting over 11 million users worldwide. The malware has been discovered spreading through malicious app downloads from Google Play and modded versions of popular apps like Spotify and WhatsApp.

Background

Necro is a family of trojan malware that has been targeting Android devices since at least 2019. The malware is known for its persistence and ability to bypass security measures. Previous variants of Necro have infected millions of devices, primarily through fraudulent advertising and phishing campaigns.

Current Attack Vector

The latest version of Necro has been found exploiting the popularity of Spotify and WhatsApp. Attackers have created modified ("modded") versions of these popular apps, which include hidden malicious code that installs the Necro malware. These modded apps are often advertised through third-party app stores and social media platforms, luring victims into downloading them.

Impact

Once installed, Necro deploys multiple payloads that can:

• Activate harmful plugins
• Run adware on infected devices
• Collect sensitive data, such as passwords and banking information
• Subscribe users to premium services without their consent
• Display intrusive advertisements

Google has responded to the threat by removing the malicious apps from the Play Store. However, users who have downloaded these apps should immediately uninstall them and scan their devices for malware. Third-party app stores and modified versions of apps remain a primary method of distribution for Necro, so caution is advised when downloading apps from untrusted sources.
