Cybersecurity researchers at Zimperium have identified a new strain of malware called RatHat, targeting Android devices and linked to threat actors from China. RatHat uses generative AI to maintain persistence and control over infected devices. The malware is typically spread through social engineering, tricking users into downloading counterfeit applications that appear legitimate. Once installed, RatHat requests accessibility permissions, activates Wireless Debugging, and can capture text messages, create overlays, and steal passwords and multi-factor authentication codes. Its AI capabilities allow it to navigate the device interface in real-time, making detection by security software more difficult. To protect against RatHat, users should avoid downloading apps from untrustworthy sources, and removal requires a factory reset of the device.

The landscape of computer security has changed significantly over the past two decades. In 2026, antivirus protection remains important, but the need for separate third-party programs has decreased for many users due to the built-in Microsoft Defender in Windows 11, which is activated by default and effectively blocks 100% of common malware samples according to independent testing by AV-TEST. Windows 11 also includes additional protective features like SmartScreen and a robust Firewall. While dedicated security suites from companies like Norton and Bitdefender offer advanced functionalities, many users may find adequate protection with the built-in tools. Research from AV-Comparatives indicates that performance varies among security programs, particularly against real-world attacks. Phishing attacks accounted for approximately 60% of initial access points in incidents examined by the ENISA Threat Landscape report from 2025, highlighting that user behavior is a significant vulnerability. Modern web browsers and operating systems have enhanced their security measures, with Google Chrome, Microsoft Edge, macOS, and Android incorporating features to protect users from harmful websites and downloads. For the average Windows 11 user who keeps their system updated and practices safe browsing, built-in protection is generally sufficient, though paid antivirus options can provide additional tools.

RuneScape: Dragonwilds introduces players to the new continent of Ashenfall, where they face the Dragon Queen Kuldra amidst a significant dragon threat. The game features a new biome called the Scorned Wilderness and a raid-style dungeon, requiring 40 to 60 hours of gameplay to complete its story content. It includes a sophisticated crafting system that allows for extensive customization of the game world. The combat system has been modernized, incorporating various weapon types and a nuanced parrying system, while the magic system offers unique runes that alter spell effects. Players experience skill progression through the use of tools or weapons, but the early game lacks healing potions, making it challenging. The game encourages exploration with a robust crafting system and in-game mounts, as well as the ability to create travel routes using loadstone teleporter panels. It also features dungeons with platforming elements and diverse enemy encounters. RuneScape: Dragonwilds supports full crossplay for consoles and has a roadmap for future updates.

More than 5,400 websites across over 2,200 organizations have been compromised to propagate malware, primarily affecting small businesses like clinics and online retailers. The attack mechanism involves malicious code that triggers a deceptive CAPTCHA, instructing users to execute commands that can download malware. Attackers are using the BNB Smart Chain test network to store instructions, making it harder for investigators to shut down operations. A newer variant of the attack uses WebRTC technology to establish encrypted connections for delivering additional malicious code. To protect against these threats, users should avoid pasting commands from websites, be suspicious of unusual CAPTCHA instructions, use strong antivirus protection, keep systems updated, take action if commands are executed, and small business owners should regularly verify their website's integrity.

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.

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.
