Microsoft resolved an authentication issue related to Credential Guard on systems using the Kerberos PKINIT pre-authentication protocol, affecting Windows 11, version 24H2, and Windows Server 2025. The problem involved improper password rotation when using the Identity Update Manager certificate, leading to user authentication issues primarily in enterprise environments. Devices failed to change passwords every 30 days, causing them to be perceived as stale, disabled, or deleted. The resolution was provided in April 2025 through Windows security updates, and Machine Accounts in Credential Guard were temporarily disabled. Microsoft advised users to install the latest updates for improvements and fixes. This is not the first authentication issue Microsoft has addressed; previous challenges occurred in November 2022 and November 2021, involving Kerberos sign-in failures and delegation scenarios.

Unified Threat Management (UTM) firewalls integrate multiple security functionalities into a single platform, streamlining security management and reducing costs for organizations, particularly small and medium-sized enterprises (SMEs). UTM solutions include features such as firewalls, intrusion detection and prevention systems (IDPS), antivirus, anti-spam, VPN, web content filtering, and application control, providing comprehensive protection against various cyber threats. UTM firewalls serve as a gateway between internal networks and external connections, inspecting all traffic to block malicious activity. They continuously monitor for suspicious patterns, scan for malware, filter web access, provide VPN capabilities for secure remote connectivity, and filter emails to protect against spam and phishing. UTM systems offer centralized management through a unified dashboard, receive regular updates for emerging threats, and may include performance optimization features. The distinction between UTM and traditional firewalls lies in UTM's broader range of security functions, acting as a comprehensive security solution rather than solely focusing on real-time malware scanning. Top UTM firewalls include: 1. SonicWall UTM: Intrusion prevention and gateway anti-virus. 2. Sophos UTM: User-friendly management with advanced security measures. 3. Check Point UTM: Comprehensive protections including firewalls and VPNs. 4. Fortinet FortiGate UTM: Integrates security and networking functions. 5. WatchGuard UTM: Balances performance, security, and management ease. 6. Juniper UTM: High-performance security services. 7. Barracuda UTM: Extensive network protection through integrated functions. 8. Stormshield UTM: Proactive defense mechanisms. 9. Huawei Unified Security Gateway (USG): Versatile security protections. 10. Cisco UTM: Integrated security and threat management services. Key features of the best UTM firewalls include application control, advanced threat prevention, reporting and analytics, scalability, endpoint protection, and DDoS protection.

A zero-day vulnerability has been discovered by researchers at Acros Security, affecting all versions of Windows from 7 to 11 and Windows Server 2008 R2 and later. This vulnerability targets the Windows NT LAN Manager and allows attackers to obtain a user's NTLM credentials by having the user view a malicious file in Windows Explorer. Currently, there is no official patch from Microsoft. The 0patch platform has released a free "micropatch" for users to protect their systems until an official fix is available.

Microsoft is testing its AI-powered Recall feature on AMD and Intel-powered Copilot+ PCs within the Windows 11 Insider program. Recall captures screenshots of active windows at regular intervals, analyzes them, and allows users to retrieve specific snapshots through natural language queries. It is an opt-in feature that requires user authentication via Windows Hello and filters out sensitive information like credit card numbers and passwords. Users can exclude specific applications or websites from being saved and have options to manage storage settings, delete snapshots, or disable the feature. Recall will support multiple languages and is expanding its availability to the European Economic Area. Additionally, Microsoft is enhancing the Microsoft Photos app with new features such as Image Creator, Restyle Image, and Click to Do for Recall, which allows text rewriting and summarization. These updates are being rolled out to Windows Insiders following the installation of a specific Windows 11 Insider Preview Build.
