The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning about the increasing threat of spyware targeting messaging applications, particularly on Android devices like Samsung. Cybercriminals are using social engineering techniques, including sending harmless-looking image files via WhatsApp, to install malicious software. Russian hackers have been reported to compromise Signal accounts. The alert highlights a focus on high-value individuals, including government officials and civil society members in the U.S., Middle East, and Europe. CISA has a history of issuing such alerts and provides cybersecurity guidance, including a "must-patch" list for federal agencies. Users are advised to be vigilant and follow mobile security guidelines, as threat groups are also using malicious QR codes and zero-click exploits to compromise devices.

Microsoft has introduced AI enhancements in Windows 11, particularly in File Explorer, featuring "Ask Copilot" and "Semantic Indexing." AI actions have been added to the context menu, allowing users to perform tasks based on file types, with integration into Microsoft 365 apps, Photos, or Paint. The rollout began with the September 2025 Security Update, but users in Europe may experience delays in access. To enable AI actions in File Explorer, users should open Settings, click on Apps, select the Actions page, and turn on the AI actions. Users can engage with AI actions by right-clicking on image files (JPG, JPEG, PNG) and selecting options like Bing Visual Search, Blur Background, Erase Objects, Remove Background, and Describe Image. If Microsoft 365 apps are installed, users can summarize documents and convert tables without opening the apps. To disable AI actions, users can follow the same steps as enabling them but turn off the AI actions instead. The "AI actions" menu will still appear, but no active features will be displayed.

Storage space is a critical consideration for mobile users, especially with the rise of 4K video files and graphically intensive games. Users can identify storage usage by accessing the Settings app and navigating to the Storage option. This allows them to see a visual representation of file types and sort them by size. Uninstalling large, unnecessary apps can free up space, but some apps may store media files internally, requiring users to delete these files within the app. For managing audio, video, and image files, deletion can be done through storage settings, while Google Photos' "free up space" feature can help remove backed-up personal photos and videos without losing them.

To enhance computer performance, ensure you are operating on the latest version of Windows. If already updated, consider using built-in utilities to reclaim disk space. Windows 11 has a feature for "Cleanup recommendations" that identifies large files and unused applications. Access it by clicking Start > Settings > System > Storage > Cleanup recommendations. The Disk Cleanup utility, available in various Windows versions, can be found by searching for "Disk Cleanup" and allows users to delete temporary internet files and cache files. To clear the location cache, go to Start > Settings > Privacy and Security > Location history and click "Clear." To flush the DNS cache, press Windows key + R, type ipconfig/flushdns, and press Enter. Regular file management and cleanup can significantly improve system performance.

A mobile ad fraud operation called "SlopAds" infiltrated the Google Play Store with 224 malicious applications, which collectively achieved over 38 million downloads across 228 countries. The operation utilized advanced steganography and obfuscation techniques to deliver fraudulent advertising payloads while avoiding detection. SlopAds activated its fraud system selectively based on specific advertising campaigns, generating around 2.3 billion fraudulent bid requests daily, primarily from the United States (30%), India (10%), and Brazil (7%). The malicious apps exploited Firebase Remote Config to retrieve encrypted data for downloading a primary fraud module named "FatModule." This module was concealed within PNG image files, allowing it to bypass traditional security measures. The FatModule included anti-analysis features to evade detection by security researchers. Google has since removed all identified SlopAds applications from the Play Store and implemented protections through Google Play Protect.

The Deployment Image Servicing and Management (DISM) tool is a command-line utility in Windows 10 used for preparing, modifying, and repairing system images, including the Windows Recovery Environment, Windows Setup, and Windows PE. It can address various system issues, and when system files are missing or corrupted, the System File Checker (SFC) can replace them using the recovery image. If local image files are compromised, the SFC command may fail, and using the "install.wim" image file with DISM can repair the image, allowing SFC to function without a complete OS reinstallation. DISM includes commands such as "CheckHealth," "ScanHealth," and "RestoreHealth" for repairing system images. The "CheckHealth" command identifies corruptions without repairing them, while "ScanHealth" performs a comprehensive scan for underlying issues. The "RestoreHealth" command scans and repairs common problems, connecting to Windows Update to download and replace damaged files if needed. If DISM encounters difficulties, an "install.wim" or "install.esd" file can be used as an alternative source for repairs. The Media Creation Tool can download a fresh Windows 10 ISO file if necessary. Specific commands can be executed to repair the image using these files, and troubleshooting common errors may involve checking for source file locations or ensuring a stable internet connection. Once the image is restored, the SFC command can be run to repair the installation of Windows 10. The SFC tool checks and repairs system files using local image files, with logs saved for further review. DISM does not delete files, and its execution time can vary based on system speed and the extent of corruption.
