This third‑party Windows 11 app fixes one of its most annoying UX problems

The Files app has been updated to version 4.0.28, featuring an improved right-click context menu, bug fixes, support for the Microsoft Store version of Dropbox, icon customization for URL and shortcut files, and an option to disable smooth scrolling. The update resolves several issues, including problems with the 'Open With' menu, tab switching, and tag searches. The development team is focused on performance improvements, particularly for thumbnail loading times. Microsoft has plans to enhance Windows 11 and address user pain points related to File Explorer.

Hackers Abuse Windows File Explorer and WebDAV for Stealthy Malware Delivery

Cybercriminals are exploiting a legacy feature in Windows File Explorer, specifically the WebDAV protocol, to distribute malware and bypass traditional security measures. Despite Microsoft deprecating native WebDAV support in November 2023, it remains active on many systems. Attackers use WebDAV to deceive victims into executing malicious payloads by sending links that connect File Explorer directly to remote servers, avoiding web browsers and their security warnings. They employ methods such as direct linking, URL shortcut files, and LNK shortcut files to deliver exploits. The primary objective of these campaigns, which surged in late 2024, is to deploy Remote Access Trojans (RATs), with 87% of Active Threat Reports involving multiple RATs like XWorm RAT, Async RAT, and DcRAT. These campaigns predominantly target corporate networks in Europe, with many phishing emails written in German and English. Attackers use short-lived WebDAV servers hosted on Cloudflare Tunnel demo accounts to obscure their infrastructure. Security analysts are advised to monitor unusual network activity from Windows Explorer and educate users to verify addresses in File Explorer.

Microsoft: New Windows LNK spoofing issues aren’t vulnerabilities

Security researcher Wietze Beukema revealed vulnerabilities in Windows LK shortcut files at the Wild West Hackin' Fest, which could allow attackers to deploy harmful payloads. He identified four undocumented techniques that manipulate these shortcut files, obscuring malicious targets from users. The vulnerabilities exploit inconsistencies in how Windows Explorer handles conflicting target paths, allowing for deceptive file properties. One technique involves using forbidden Windows path characters to create misleading paths, while another manipulates LinkTargetIDList values. The most sophisticated method alters the EnvironmentVariableDataBlock structure to present a false target in the properties window while executing malicious commands in the background. Microsoft declined to classify the EnvironmentVariableDataBlock issue as a security vulnerability, stating that exploitation requires user interaction and does not breach security boundaries. They emphasized that Windows recognizes shortcut files as potentially dangerous and provides warnings when opening them. However, Beukema noted that users often ignore these warnings. The vulnerabilities share similarities with CVE-2025-9491, which has been exploited by various state-sponsored and cybercrime groups. Microsoft initially did not address CVE-2025-9491 but later modified LNK files to mitigate the vulnerability after it was widely exploited.

Windows shortcut files targeted by ransomware gang Global Group

The Global Group ransomware operates in a mute mode, executing all activities locally on the compromised system without communicating with a command and control server. It generates the encryption key directly on the host machine, meaning no data is exfiltrated despite claims in its ransom note. This method streamlines the attack process, minimizes detection risks, and allows for quicker execution of attacks, targeting more victims while making data exfiltration unnecessary for compelling ransom payments.

Microsoft fixes six actively exploited flaws in latest Windows 11 update

Microsoft's February 2026 Patch Tuesday addressed 59 vulnerabilities in Windows 11, with six confirmed as actively exploited. The most critical vulnerability is CVE-2026-21510, a Windows Shell security feature bypass with a CVSS rating of 8.8, allowing attackers to evade warnings by tricking users into opening malicious files. Another significant vulnerability, CVE-2026-21513, also rated at 8.8, affects MSHTML and allows remote attackers to bypass execution prompts through malicious code in HTML or shortcut files. CVE-2026-21514 impacts Microsoft Word and enables adversaries to disable OLE mitigations, posing risks through document-based attacks. Two local privilege escalation vulnerabilities are CVE-2026-21519 in Desktop Window Manager and CVE-2026-21533 in Windows Remote Desktop Services, with CVSS scores of 7.8. CVE-2026-21525 is a denial-of-service vulnerability in Remote Access Connection Manager. The update includes 53 additional vulnerabilities across various Microsoft products and services, with CVE-2026-21531 in Azure SDK rated at 9.8 and CVE-2026-20841 affecting Windows Notepad rated at 8.8. The cumulative update for Windows 11 (KB5077181) also includes enhancements and resolves WPA3 Wi-Fi connectivity issues. Microsoft reminded users of the June 2026 expiration of Secure Boot certificates, which requires timely updates to ensure secure booting. Users can install the updates via Windows Update.

Global Group ransomware gang running new campaign using Windows shortcut files

The Global Group ransomware operates entirely in silent mode, executing all activities locally on the compromised system without relying on a command and control server. It generates the encryption key directly on the host machine, resulting in no actual data exfiltration despite claims in its ransom note. This approach allows for quicker attacks, targeting a broader range of victims while reducing detection risk. The act of encryption alone can compel payment due to significant operational downtime for affected organizations.

Windows shortcut weaponized in Phorpiex-linked ransomware campaign

The Global Group has shifted to a local execution strategy for ransomware, complicating detection and response efforts. Their infection process begins when a user opens a shortcut file with a double extension (e.g., “Document.doc.lnk”), which appears as a legitimate document due to Windows' default settings that hide file extensions. The shortcut icon mimics that of a Microsoft Word file. When executed, the .lnk file activates Windows utilities like cms.exe and PowerShell to retrieve and execute the next-stage payload, effectively bypassing traditional security controls focused on malicious documents or executable attachments.

Microsoft Silently Fixes 8-Year Windows Security Flaw

Microsoft addressed a critical vulnerability in Windows, identified as CVE-2025-9491, which had existed for nearly eight years and allowed cybercriminals to conceal malicious commands within .LNK (shortcut) files. This flaw was exploited by state-sponsored hacking groups from countries including China, Iran, North Korea, and Russia, with evidence of nearly 1,000 malicious shortcut files used in various campaigns. The vulnerability was initially downplayed by Microsoft, which stated it did not require immediate servicing. However, as exploitation increased, Microsoft eventually included a fix in its November 2025 Patch Tuesday updates, which was not publicly announced. The fix allows the entire Target command to be displayed in the Properties dialog, addressing the security risk. Research indicated that around 70% of campaigns exploiting this flaw were focused on espionage and information theft across multiple sectors.

Microsoft Patches Widely Exploited Windows LNK Zero-Day

Cybercriminals are exploiting a vulnerability in Windows LNK (.lnk shortcut) files, identified as CVE-2025-9491, to deliver malware in targeted attacks. This flaw allows attackers to hide malicious commands within shortcut files, which execute when a user opens the crafted shortcut, leading to malware installation. The vulnerability has been actively exploited by at least 11 threat actor groups, including Evil Corp and Mustang Panda, with malware such as Ursnif and Trickbot being delivered through this exploit. Microsoft released a patch for this vulnerability in November 2025 after initially delaying it, citing the need for user interaction to trigger the exploit. Security recommendations include avoiding suspicious .LNK files, implementing strict email filtering, and applying the latest security updates.
