MoqHao: The Android malware that runs itself automatically

Introduction

Researchers specializing in cybersecurity have detected a fresh variant of Android malware known as MoqHao, which exhibits a unique behavior of self-execution on compromised devices, bypassing the need for user interaction. McAfee Labs disclosed this discovery, noting that unlike conventional MoqHao strains, which rely on user activation post-installation, this new version triggers its malicious operations immediately upon installation.

Targeted Countries and Associations

The targets of this new malware primarily encompass Android users situated in France, Germany, India, Japan, and South Korea. MoqHao, alternatively labeled as Wroba and XLoader, is associated with the Roaming Mantis, a cybercrime syndicate originating from China. The dissemination of the malware occurs through SMS messages containing deceptive links, prompting installation upon interaction, with Android users redirected to counterfeit Apple iCloud login pages when accessed through iPhones.

Enhanced Functionalities and Tactics

A similar virus has been reported in July 2022 affecting over 70,000 Android devices in France. Recent iterations of MoqHao have showcased enhanced functionalities, including the infiltration of Wi-Fi routers and engagement in DNS hijacking. Notably, the latest variant adopts smishing techniques but sets itself apart by automatically executing the malicious payload upon installation, compelling victims to grant intrusive permissions without initiating the app.

Refined Strategies and Features

Furthermore, the attackers have refined their strategies by concealing malicious links through URL shorteners and sourcing message content from fictitious Pinterest profiles. MoqHao boasts features enabling the covert harvesting of sensitive data, such as device particulars, contacts, SMS messages, and images, while also facilitating silent calls and managing Wi-Fi connectivity.

Mitigation Efforts and New Threats

McAfee has notified Google regarding these findings, prompting efforts to integrate mitigative measures into forthcoming Android releases. Concurrently, QiAnXin, a Chinese cybersecurity firm, unveiled the emergence of a novel cybercrime faction named Bigpanzi, implicated in compromising Android-based smart TVs and set-top boxes (STBs) to establish a botnet for executing distributed denial-of-service (DDoS) attacks.

Bigpanzi's Operations and Implications

Operational since 2015, Bigpanzi's botnet comprises an estimated 170,000 daily active bots, primarily concentrated in Brazil. However, since August 2023, 1.3 million distinct Brazilian IP addresses have been linked to Bigpanzi. Infections are facilitated through deceptive apps offering pirated content streaming, as disclosed by Doctor Web in September 2023.

Upon installation, compromised devices transition into operational nodes within the illicit streaming platform, enabling activities such as traffic proxying, DDoS assaults, and the dissemination of pirated content. The potential for Bigpanzi-controlled devices to propagate harmful content or engage in propaganda activities underscores the threat to societal stability.

Cautionary Advice for Android Users

Android users should exercise vigilance when interacting with unsolicited messages or downloading apps from unofficial sources. Stay cautious of suspicious links, especially those received via SMS or from unfamiliar contacts. Ensure your device's security settings are up-to-date and consider using reputable antivirus software to mitigate the risk of malware infections. Remember, protecting your device means safeguarding your personal data and contributing to a safer digital environment for all users.
