For nearly two months, Windows 11 users received persistent notifications from the Windows Security app falsely indicating that Microsoft Defender was disabled, despite it functioning properly. This issue, which began in early August, has been addressed with a security update from Microsoft. The false alerts affected all versions of Windows 11, Windows Server, and Windows 10, and were linked to a bug introduced with a recent Defender security update. Microsoft confirmed that no manual action is required from users to resolve the issue, as the fix will be automatically deployed to all PCs with mandatory security updates enabled. The problem was resolved in the Microsoft Defender Antivirus update (version 4.18.26080.4), released on September 17, 2026. Users can verify the status of Defender by checking Windows Security or using a PowerShell command.

Valve has open-sourced Lepton, an Android compatibility layer for the Steam Frame headset, allowing VR developers to adapt existing Android games for the device. The code is available on Valve's GitLab repository and facilitates the transition without needing to reconstruct games for a different platform. Lepton is designed to create a game-optimized Android environment rather than transforming the Steam Frame into a general Android device. It disables unnecessary Android services to maintain efficiency and integrates with the SteamOS host system, supporting various graphics stacks and Vulkan tools for enhanced VR gaming. Lepton operates without requiring root access, with each process running as a non-root user, and provides developers with tools for debugging and performance profiling. The open-sourced code offers insight into Valve's approach to supporting Android games on SteamOS.

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.

Microsoft has released a modernized version of the Mouse Indicator in Windows 11 Insider Preview Build 26340.9502 on September 18, 2026. This update features a new animation that can be activated through Accessibility settings, allowing users to keep the indicator on until they press the Esc key. Users can choose to activate the Mouse Indicator with a single or double Ctrl press. The previous version displayed a simplistic circle around the pointer briefly, while the new version offers a smoother, more dynamic animation. The feature is currently available only in the Insider build for the Experimental channel, and users can enable it by navigating to Settings > Accessibility > Mouse pointer and touch > Mouse indicator.

Google has launched Android Bench 2.0, an upgraded benchmark for evaluating AI coding agents, which now includes 30 long-horizon tasks that can take human engineers days or weeks to complete. The best pass rate for these tasks is around 28%, down from approximately 91% in the previous version. The benchmark measures both pass rates and completion rates, acknowledging partial progress rather than just failures. It assesses various challenges, including app creation and feature integration, using a comprehensive scoring methodology that evaluates functionality, regression checks, and visual fidelity. AI models perform better with new code than with modifications to existing systems, facing challenges in runtime validation and cross-platform conversions. The current leaderboard shows OpenAI’s GPT-6 Astra leading with a 28% pass rate, while Gemini 3.8 Flash has an 8% pass rate. Developers using AI agents should be aware that while AI can generate significant portions of applications, further refinements will require human input. The benchmark is available on Google’s Android Bench leaderboard.

A new Android malware called RatHat has emerged, analyzed by researchers from Zimperium's zLabs. It spreads through deceptive smishing texts and malicious ads that lead users to counterfeit download pages for popular apps. Once installed, it manipulates Android's Accessibility Service to gain elevated access by enabling Wireless Debugging and retrieving authentication codes without user intervention. RatHat targets finance and banking apps to steal user IDs, passwords, and MFA codes, using techniques to obtain touch coordinates for PIN recovery. It can intercept SMS messages, gain limited control of the device, and reinstall itself. Users are advised against sideloading apps and granting unnecessary accessibility permissions. Google's Advanced Protection Mode and Malwarebytes for Android can help mitigate risks associated with RatHat.

Security researchers have identified an Android banking Trojan named RatHat, which utilizes artificial intelligence, accessibility features, and Android Debug Bridge (ADB) to steal financial credentials, PINs, and one-time passcodes. Unlike traditional malware, RatHat employs a live AI assistant that interacts with the Android accessibility tree, allowing it to make real-time decisions based on the victim's screen content. The infection typically starts with social-engineering tactics, leading victims to counterfeit download pages where they are tricked into sideloading a malicious APK. Once installed, RatHat prompts users to enable Android Accessibility Service permissions, which it exploits to navigate Developer Options and enable Wireless Debugging. This grants it shell-level ADB access, allowing it to bypass application sandbox restrictions. RatHat deploys two native binaries for executing commands and maintaining a connection to the attacker's infrastructure. It targets banking applications through credential-stealing overlays and can intercept SMS messages for transaction verification codes. Additionally, it can record touch coordinates to reconstruct PINs and unlock patterns. RatHat includes persistence mechanisms to restore itself after removal, and users are advised to perform a factory reset if they suspect compromise. To reduce infection risk, users should avoid sideloading apps from unknown links, deny unnecessary Accessibility Service requests, and refrain from enabling Developer Options or Wireless Debugging for unfamiliar applications.
