Cybersecurity experts at Doctor Web have identified a new variant of Android malware called Android.Backdoor.916.origin, active since January 2025. This malware can eavesdrop on conversations, steal messages, stream video, and log keystrokes. It targets Russian business representatives rather than average users, being distributed through direct messages as a fake antivirus app named GuardCB, which mimics the Russian Central Bank's emblem. The app requests extensive permissions, including geolocation, audio recording, camera access, and SMS data, and can function as a keylogger. It is designed for persistence, launching background services and communicating with multiple command-and-control servers. The malware can livestream audio, broadcast video, capture text, and upload contacts and call history. It exploits Android’s Accessibility Service to capture keystrokes and prevent uninstallation. The interface is exclusively in Russian, indicating it is specifically designed for a targeted group. Users in Russia are advised to download applications only from trusted sources to mitigate risks.

This week, a new main menu panorama has been introduced, along with a comprehensive Code of Conduct for servers and ongoing enhancements with Copper Golems. Snapshot 25w34b has been released, addressing connectivity errors with Realms. New features include an in-game Code of Conduct that players must accept to access a server, with an option to opt out of future displays unless updated. A new boolean field, enable-code-of-conduct, has been added to server.properties to manage this feature. The main menu has been updated to feature Copper Golems. The sound effect for the End Light Flashes has an increased delay, and the accessibility setting "Hide Lightning Flashes" has been renamed to "Hide Sky Flashes." Copper Golems will now have invisible eyes when splashed with a Potion of Invisibility, and their hitbox has been adjusted to allow navigation through open doors. Sounds associated with Copper Golems and Copper Chests can now be heard from up to 12 blocks away, with modifications to the volume of copper sorting sounds. The Data Pack version has been updated to 84.0, introducing a new fetchprofile command for downloading player profiles. The alignitemsto_bottom block state property has been removed from the Shelf block. Fixed bugs in 25w34b include issues with glowing items, world selection screen overflow, and various interactions with Copper Golems and other entities. Snapshots are available for Minecraft: Java Edition, and players are advised to back up their worlds before installation.

Users of Windows 11 have experienced inconsistencies with dark mode, as some dialog boxes remain white despite the overall dark theme. A new beta feature in Windows 11 Insider Beta and Dev builds allows File Explorer dialog boxes to adopt a dark mode appearance, which was previously unavailable. This feature can be accessed by users on specific Insider builds (26120.5751 for Beta or 26200.5751 for Dev) released on August 15, 2025. To enable the dark mode dialog boxes, users must use ViveTool, a utility that unlocks hidden features, and execute specific commands after installing the Insider build. Although the dark mode dialog boxes are now available, some buttons within them may still appear in gray, indicating that Microsoft is still refining this aspect of the user interface. Other windows, such as the Run dialog box and Control Panel, still show inconsistencies in color schemes.
