Microsoft released updates in June 2025 to address critical issues affecting Windows Server 2025 domain controllers, specifically authentication failures and network connectivity problems. The updates, encapsulated in KB5060842, resolved issues stemming from security update KB5055523, which altered certificate validation methods for Kerberos authentication. This change led to logging errors for self-signed certificates and affected Windows Hello for Business Key Trust deployments. Additionally, a separate issue prevented domain controllers from managing network traffic correctly after restarts, causing them to revert to standard firewall profiles. Microsoft provided a temporary workaround for administrators to manually restart network adapters until a permanent fix was implemented. The June updates addressed a total of 66 vulnerabilities, including 10 rated as Critical, and recommended immediate installation. Microsoft advised against setting the AllowNtAuthPolicyBypass registry key to ‘2’ for domain controllers using self-signed certificates until the latest updates were applied.

Microsoft has released a patch, KB5060842, on June 10, 2025, to address a vulnerability in Windows Server 2025 that affected Active Directory Domain Controllers' ability to manage network traffic after system restarts. This issue stemmed from the improper initialization of domain firewall profiles during startup, leading to service interruptions and authentication failures. The patch corrects the initialization sequence of these profiles, ensuring proper network traffic management post-restart. Organizations using Windows Server 2025 are advised to implement this update to maintain the reliability of their Active Directory services.

Microsoft addressed a significant issue with Windows Server 2025 domain controllers that made some servers unreachable after a restart, affecting applications and services reliant on them. The problem was due to servers loading the standard firewall profile instead of the intended domain firewall profile after a reboot, leading to improper network traffic management. This misconfiguration caused accessibility challenges for services and applications on affected servers. Microsoft released the KB5060842 security update to resolve this issue during the June 2025 Patch Tuesday. A temporary workaround involves manually restarting the network adapter on affected servers using the Restart-NetAdapter * PowerShell command, which must be done after each reboot until the update is installed. Additionally, Microsoft fixed another issue preventing some users from logging into accounts via Windows Hello after the installation of the KB5055523 April 2025 security update.

In recent months, the use of Windows Packet Divert drivers in Russia has surged, nearly doubling between August 2023 and January 2024, primarily for tools that bypass access restrictions to foreign resources. Cybercriminals are exploiting this trend by distributing malware disguised as these tools, with some bloggers unknowingly promoting such malicious programs. An investigation revealed that a YouTube channel with 60,000 subscribers posted videos on bypassing restrictions, linking to a malicious archive that had been downloaded over 40,000 times. The malware, a variant of SilentCryptoMiner, is designed to mine cryptocurrencies while evading detection. Users are advised to ensure their devices have trusted protection, avoid obscure downloads, and be cautious of even reputable bloggers who may inadvertently share malware.
