Microsoft is changing Windows to restrict security software from operating at the kernel level to reduce vulnerabilities. This decision follows a flawed update from CrowdStrike that crashed over 8.5 million Windows machines. Microsoft is collaborating with security firms like CrowdStrike, Bitdefender, ESET, and Trend Micro to create a new security platform, emphasizing a cooperative approach rather than dictating terms. The transition will start with a private preview for security companies, initially affecting antivirus and endpoint detection software, with plans to include other applications later. Microsoft is also introducing a Quick Machine Recovery feature to restore systems that fail to boot and replacing the "Blue Screen of Death" with a black screen as part of its updates.

Microsoft will retire the Windows Blue Screen of Death (BSOD) in favor of a black screen as part of the Windows Resiliency Initiative (WRI), with the change rolling out later this summer for Windows 11 version 24H2 devices. This update follows a security incident in July 2024 that affected approximately 8.5 million Windows machines. The WRI aims to enhance system resilience by reengineering Windows code and allowing security software to operate outside the Windows kernel, minimizing risks from vendor security code. A private preview of the new Windows endpoint security platform will be available to Microsoft Virus Initiative partners next month.

Microsoft is preparing to initiate a private preview of new Windows changes aimed at relocating antivirus (AV) and endpoint detection and response (EDR) applications away from the Windows kernel. This initiative follows a significant incident involving a faulty update from CrowdStrike that disrupted 8.5 million Windows-based machines globally. Microsoft is collaborating with industry leaders such as CrowdStrike, Bitdefender, ESET, and Trend Micro to develop a new endpoint security platform. The company is engaging its top engineers, including original architects of Windows, to work on these security enhancements. The upcoming private preview will allow security vendors to suggest modifications, with several iterations anticipated before the final version is ready. Microsoft is also addressing concerns related to kernel-level drivers in anti-cheating engines for gaming and is engaging with game developers on minimizing kernel usage. A forthcoming Windows update will introduce a Quick Machine Recovery feature to expedite restoration of machines encountering boot issues. Additionally, Microsoft is redesigning the Blue Screen of Death (BSOD) from blue to black as part of its commitment to enhancing user experience and system reliability.

A newly identified exploit called "FileFix" manipulates Windows File Explorer to execute harmful commands while remaining within a web browser. Developed by security researcher mr.d0x, it builds on the ClickFix social engineering attack. FileFix uses the file upload feature on websites, prompting users to copy a malicious PowerShell command disguised as a file path. When users paste this path into the File Explorer address bar, it executes the command without their knowledge. The attack exploits familiar workflows, bypassing user skepticism and does not require elevated privileges or complex malware. Security experts warn that FileFix could enable the delivery of infostealers, ransomware, or other malware, posing a significant risk to individuals and organizations. Users are advised to be cautious of instructions to copy and paste file paths from unfamiliar sources, monitor for suspicious processes initiated by browsers, and keep security software updated.

A new browser-based malware campaign exploits trusted domains like Google.com to bypass traditional antivirus defenses. The malware operates through an e-commerce site using a manipulated Google OAuth logout URL, which executes an obfuscated JavaScript payload. This script activates silently during checkout or when the browser appears automated, opening a WebSocket connection to a malicious server. Payloads are dynamically executed using JavaScript, enhancing the threat's effectiveness. The attack evades detection by many antivirus programs due to its obfuscation and conditional activation. DNS filters and firewall rules offer limited protection since the initial request goes to a legitimate domain. Advanced users may use content inspection proxies or behavioral analysis tools to detect anomalies, but average users remain vulnerable. Recommendations to mitigate risks include limiting third-party scripts and maintaining separate browser sessions for financial transactions.

Robust antivirus software is essential for protecting sensitive data in personal and business contexts. Different antivirus solutions vary in malware detection and overall protection. The ideal antivirus balances comprehensive coverage with system performance. Resources like AV-Comparatives and AV-Test provide impartial testing of antivirus capabilities, including real-world protection tests and evaluations of false alarms. Performance and customer support are critical factors in antivirus software evaluation. The impact on device speed and resource consumption is important, as is the quality of customer support for troubleshooting. Reliable support options enhance user satisfaction. Thorough testing of antivirus software is crucial due to the evolving tactics of cybercriminals. Not all antivirus solutions are equally effective, and rigorous evaluation helps identify subpar options and false positives. Free antivirus options may suffice for casual users, but premium versions often offer better features and protections. Meticulous testing ensures that security software meets its promises and helps users make informed decisions.

All modern Windows PCs come with Microsoft Defender, a built-in antivirus solution. A tool called Defendnot can disable Microsoft Defender by tricking Windows into believing another antivirus is active. It uses an undocumented API to register a counterfeit antivirus, which leads to Microsoft Defender being automatically disabled without user notification. Defendnot creates a scheduled task for persistence and allows customization of the antivirus name. It is a successor to a previous project, No-Defender, which was removed due to copyright issues. Currently, Microsoft Defender flags Defendnot as a threat.
