Challengers Approach: Third Party App Stores Arrive to Google Play

Google has begun allowing rival, third-party app stores to be included within the Google Play Store, providing developers with more options for billing and app distribution. This change follows a court order resulting from Epic Games' antitrust lawsuit against Google, which challenged the company's restrictions on alternative app stores and in-app payment rules. The inclusion of these third-party stores enhances competition within the Android ecosystem, reducing Google's dominance and empowering users and developers with more choices. Users can now opt for alternative app stores if they are dissatisfied with Google's services, improving opportunities for privacy and security.

Decades-old file security flaws found in Android, Linux, macOS, and Windows

Security researchers from Graz University of Technology in Austria have discovered significant vulnerabilities in the file notification systems of major operating systems: Android, Linux, macOS, and Windows. These flaws have existed for decades and can lead to the leakage of sensitive system information. The affected systems include inotify on Linux (since 2005), FileObserver on Android (since 2008), ReadDirectoryChangesW on Windows (since 2000), and FSEvents on macOS (since 2007). The vulnerabilities allow unprivileged users to monitor file events without explicit read permissions, enabling potential attacks such as inter-keystroke timing attacks and website fingerprinting. For example, on Linux, monitoring a readable directory can leak events on files that cannot be read, allowing attackers to achieve a 93.1% to 100% accuracy rate in monitoring keystrokes. Specific vulnerabilities include CVE-2025-68788 on Linux, which received a partial fix in December 2025, and issues on Android where FileObserver can bypass app storage isolation. On macOS, limited information is available due to a lack of bypasses for private directories, while on Windows, monitoring the root directory can reveal the full path of every accessed file, allowing real-time tracking of web activity with a 97.8% accuracy rate. Microsoft has described the issue as "by-design," which has faced criticism. The researchers propose stronger mitigations, such as disallowing monitoring of entire drives on Windows and introducing a permission system for file monitoring on Windows and macOS. Their findings will be presented at the ACM CCS 2026 conference in November in The Hague, Netherlands.

Russia’s national messenger app Max found to contain backdoor capable of secret screen captures

Researchers have found that Max, a messaging app mandated by the Russian government, can secretly capture screenshots, access sensitive information, impersonate users, and inject code into other applications. Developed by VK, the app integrates messaging, banking, and government services. Since September 1 of last year, it has been preinstalled on new smartphones, following the blocking of WhatsApp and Telegram. Despite its reach, it is not widely used in political circles, with insiders indicating that compliance with its use is performative.

How to measure and shrink the Windows search index

The initial storage cost of the search index on a fresh installation of Windows 11 is minimal, only a few megabytes. When a sizable work folder is added, the index expands, but it does not revert to its original size after the folder is removed. The search index is stored in Windows.db for Windows 11 and Windows.edb for Windows 10. Windows 11 has two indexing modes: Classic (default) and Enhanced, with Classic indexing Documents, Pictures, Music folders, and the Desktop, while Enhanced scans the entire PC. The index includes file names and content, allowing keyword searches. Users can measure their index items through Settings without special permissions, while file size requires administrative access via PowerShell. An index under 30,000 items is acceptable for average users, while performance issues may arise beyond 400,000 items, with a technical ceiling of one million items. In an experiment, the index grew from 462 items and 6.71 MB to 3,466 items and 18.66 MB after adding 3,000 text files, but remained at 16.81 MB after deleting those files. To reclaim disk space, users can exclude specific folders from indexing and rebuild the index, which can significantly reduce its size while retaining the same number of items.

7 Ways To Use Private Space On Your Android Device That Are Actually Helpful

Google's Private Space is a feature on Android devices that creates a secure environment for managing sensitive information. It allows users to lock banking apps, providing a secure vault that is hidden from the main interface and protected from malware and unauthorized access. Users can enhance security with a unique PIN or biometric authentication, and the space locks automatically when the smartphone is secured. Private Space also serves as a secure repository for personal documents, enabling users to move files like PDFs and IDs into it, ensuring they remain inaccessible until the space is locked. Additionally, Private Space allows users to separate personal and professional digital lives by logging into a different Google account, maintaining distinct emails, contacts, and calendar events. Users can install separate instances of messaging and social media apps within Private Space to manage multiple accounts securely. It also helps keep dating apps hidden, protecting users' privacy and personal data. When sharing devices, Private Space ensures personal data remains secure behind authentication. Lastly, it allows users to store data locally without syncing to the cloud, prioritizing privacy over convenience.
