New Android spyware Morpheus linked to Italian surveillance firm

Morpheus is a new spyware identified by the nonprofit organization Osservatorio Nessuno, which spreads through counterfeit Android applications that appear as legitimate updates. Attackers use SMS messages to direct victims to a fraudulent website mimicking an Internet Service Provider (ISP). The spyware installs a dropper app that deploys a concealed payload, which disguises itself as legitimate system components and manipulates users into granting dangerous permissions, including Accessibility access. Once granted, Morpheus initiates a Permission Workflow that creates a fake update overlay, disabling the touchscreen to prevent user interaction. It ensures persistence by restarting after device reboots and can request device administrator privileges. The spyware exploits overlay windows and Accessibility features to gain control of the device and bypass security measures, including disabling antivirus solutions without requiring root access. Analysis suggests Morpheus has Italian origins, with connections to an Italian firm, IPS Intelligence, known for lawful interception technologies. The spyware is capable of invasive actions such as recording audio and video, linking to WhatsApp, and compromising device security. The report highlights a network of dubious companies and shared contacts linked to the spyware's distribution.

Google Responds As 50 Apps With 2 Million Downloads Hit By Malware

Researchers at McAfee Labs discovered that 50 Android applications on the Google Play Store contain malware known as NoVoice, which can grant full remote access to infected smartphones. These apps have over 2.3 million downloads. The malware can communicate with remote servers, profile devices, and download tailored root exploits, potentially compromising specific hardware and software configurations. However, devices with an Android security patch level of May 2021 or later are not vulnerable to these exploits, as the vulnerabilities were patched by Android between 2016 and 2021. Google Play Protect removes these apps and blocks new installs, and users are advised to keep their devices updated with the latest security patches.

Android security gets aggressive as Google bans thousands of developers and millions of sketchy apps

Google has reported significant improvements in app security for Android in 2025, preventing over 1.75 million policy-violating apps from entering the Play Store and removing more than 80,000 developer accounts attempting to distribute malware.

Additionally, Google blocked over 255,000 apps from requesting unnecessary sensitive data and eliminated 160 million spam ratings and reviews. Google Play Protect now evaluates over 350 billion apps daily, identifying 27 million new malicious apps outside the Play Store and blocking 266 million risky installation attempts across 185 markets. A new measure has been implemented to prevent users from disabling Play Protect during phone calls to combat social engineering tactics. Future plans include democratizing developer verification and simplifying protection against "tapjacking" attacks in Android 16.

New backdoor found in Android tablets targeting users in Russia, Germany and Japan

Researchers from Kaspersky have discovered an Android backdoor named Keenadu, embedded in the firmware of devices, allowing it to infect tablets before they reach consumers. This malware, affecting over 13,700 users globally, primarily targets advertising fraud by hijacking browser search engines, monitoring app installations, and generating fraudulent revenue. Tablets from various manufacturers, including Alldocube, have been found compromised, with the malware likely inserted during the firmware build stage through a compromised supply chain. Keenadu has multiple variants, some hidden in applications, and employs evasion tactics based on device language settings and time zones. It cannot be removed using standard Android security tools, and users are advised to install clean firmware or replace their devices entirely.

Before You Download a Minecraft APK, Read This

Minecraft is one of the most downloaded games in history, leading to a high demand for free or modded APK versions, particularly among Android users. Downloading unofficial Minecraft APKs is generally unsafe due to several risks: 1. High malware infection rates: Gaming APKs are significant conduits for Android malware, with Minecraft APKs frequently flagged. Reports indicate that game-related APK downloads account for 19% to 28% of Android trojan distribution cases. 2. Fake Minecraft APK sites often engage in phishing: Over 50% of such sites feature intrusive ads or misleading download buttons, and nearly 30% redirect users to phishing landing pages. 3. Modified APKs may request dangerous permissions: Many modified APKs ask for permissions that exceed basic functionality, such as access to SMS, device admin privileges, and the microphone and camera. 4. Lack of automatic updates creates long-term security vulnerabilities: APKs from external sites do not receive automatic updates, may contain known vulnerabilities, and can be replaced by more harmful versions. An example is given of a user named John, who downloaded a seemingly harmless APK that contained hidden spyware, leading to issues with his device and privacy. Many users download Minecraft APKs to avoid purchase costs, but the risks to their devices and data are significant.

Syncthing Android App Ends in 2024: Community Forks Tackle Google Hurdles

Syncthing, an open-source file synchronization tool, faced discontinuation of its official Android app in late 2024 due to Google's strict Play Store policies and lack of maintenance. In response, the community developed the Syncthing-Fork as an alternative, which integrates the core Syncthing engine and offers enhancements for Android users. The fork's development is now maintained under the researchxxl/syncthing-android repository on GitHub, addressing issues like file synchronization problems caused by Android's battery optimization features. Users have reported sync failures during device sleep, prompting discussions on workarounds. The fork has received positive feedback for its regular updates and compatibility with other tools, although challenges remain, such as intermittent issues with larger file transfers. Community involvement has been crucial for ongoing development, with contributors exploring new features and improvements. The fork is also available on F-Droid, providing an open-source distribution option.
