BigDiskBuster PoC Blocks Windows Defender Updates

A new tool named BigDiskBuster has been released on GitHub, which disrupts Microsoft Defender Antivirus by preventing it from installing updates. It does this by consuming available disk space during the update process, causing Defender to remain on its current version and unable to receive new platform or signature updates. BigDiskBuster operates as a local denial-of-service technique and requires prior access to the target machine to execute. The tool was created by researcher Abdelhamid Naceri, known as Nightmare Eclipse, who has previously worked on similar projects. As of now, there is no CVE identifier, patch, or advisory from Microsoft regarding this issue.

New RatHat Android Malware Uses AI to Steal Banking Logins, PINs and OTP Codes

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.

Notebooks in Gemini arrive for Google Workspace and Education accounts

Google has rolled out the "Notebooks in Gemini" feature to business and education accounts in Google Workspace, following its integration for regular users that began in April. The feature, previously known as NotebookLM, is now part of the main Gemini interface, allowing users to create interactive learning materials, reports, and slide decks. Workspace administrators can control access to the feature, which must be enabled at the organizational level. Users in the European Economic Area (EEA) do not have access to this feature due to regional restrictions on artificial intelligence applications.

RatHat Android Malware Abuses ADB to Retain Shell Access After Uninstall

Cybersecurity experts have identified a new Android malware named RatHat, believed to be operated by Chinese threat actors. RatHat is distributed primarily through smishing and malvertising campaigns, leading users to deceptive download portals. It employs an automated multi-stage infection process and exploits Accessibility features along with a local ADB self-pairing mechanism to escape the Android application sandbox. The malware uses various anti-analysis techniques, including container tampering, manifest bombs, DEX bytecode poisoning, and dual string-encryption. RatHat's architecture consists of a malicious Android application, a Go agent, and an FRP reverse-proxy client, which together enable it to gain critical system permissions and perform various malicious activities such as credential capturing, screen recording, and SMS interception. Even if uninstalled, the malware retains shell access to the device, allowing attackers to reinstall it. RatHat can serialize the device's Accessibility tree to XML and communicate with a Generative AI assistant for tasks like screen coordinate determination and text extraction. The Go Agent, masquerading as a native library, exploits shell access to execute commands and establish a persistent connection to a command-and-control server via the FRP client. The C2 server can issue extensive commands to collect sensitive information, including SMS messages, credentials, files, and keystrokes, and RatHat also features a hardware-level keylogger.

Android Bench 2.0 focuses on long-horizon tasks, agent evaluations

Google has released version 2.0 of Android Bench, which focuses on managing complex development tasks rather than minor adjustments. The new version evaluates tasks that may take engineers days or weeks to complete, such as adding features and building applications. A continuous scoring method has replaced the previous pass or fail system, assessing completion rates based on functionality, visual fidelity, and adherence to instructions. Various AI models have been tested, with GPT-6 Astra achieving a 28% pass rate, significantly lower than the previous scores around 90%. No model has achieved a 100% pass rate in porting cross-platform applications, with the best reaching 80%. AI performs better in writing new code than in refactoring existing code, facing challenges with architectural complexity and runtime validation. Android Bench utilized agents from model providers for evaluations and plans to incorporate various model combinations in future updates.

Microsoft Azure CTO used AI to port 20-year-old Windows tool to macOS in two days: “I was flabbergasted”

Mark Russinovich, the Chief Technology Officer of Microsoft Azure, transitioned ZoomIt, a Windows tool for screen zooming, recording, and annotation, to macOS using artificial intelligence. Originally developed to aid in teaching Windows Internals, ZoomIt has been enhanced over the years with features like screen recording and webcam overlays. Despite initial reluctance due to time constraints, Russinovich utilized AI to create a functional macOS version in just two days, significantly faster than anticipated. The AI model leveraged the original Windows code, allowing for a high-fidelity clone of ZoomIt that includes essential features. ZoomIt for macOS is now available as a free and open-source tool, requiring macOS 14 Sonoma or newer, and can be installed via Homebrew or from Microsoft’s GitHub repository. Users can access its functionalities through keyboard shortcuts and a menu bar icon.
