Microsoft has introduced DNS over HTTPS (DoH) on Windows Server 2025, enhancing network security by encrypting DNS traffic for client-to-server communications. This feature, previously available only in Windows client editions, is now part of Microsoft's Zero Trust architecture. DoH routes DNS traffic through HTTPS secured with TLS certificates, preventing eavesdropping and safeguarding DNS data from tampering. It adheres to the IETF DNS over HTTPS standard (RFC 8484) and can integrate with existing infrastructure, allowing organizations to maintain unencrypted DNS traffic if needed. DoH is available for Windows Server 2025 systems updated to the latest Patch Tuesday release, and Microsoft has provided guidance on enabling this feature. However, DNS traffic exchanged between two DNS servers will not be encrypted by DoH.

Microsoft has rolled out support for DNS over HTTPS (DoH) in Windows DNS Server as part of the Windows Server 2025 update. This feature enhances the security of DNS communications through encryption and server authentication, allowing encrypted client-to-resolver traffic in on-premises DNS environments. DoH encrypts DNS queries and responses using HTTPS, protecting sensitive information from interception or alteration. It also uses digital certificates for DNS server authentication to reduce spoofing and impersonation risks. The feature is compatible with existing Windows DNS Server configurations and supports both encrypted and traditional DNS. DoH support is available on Windows Server 2025 with the June 9, 2026 update or newer. Administrators must configure a trusted TLS certificate and enable DoH in the DNS Server service to deploy this feature. Microsoft plans to extend encryption capabilities to include communication between the Windows DNS Server and upstream DNS resolvers in the future.

Active Directory Certificate Services (ADCS) now supports the generation of post-quantum certificates, enhancing quantum-safe cryptography within Windows' secure connection protocols. Microsoft has integrated PQ TLS hybrid key exchange into the Windows Transport Layer Security (TLS) stack, providing protection against "Harvest Now, Decrypt Later" attacks. The PQ TLS hybrid key exchange combines traditional cryptographic methods with the NIST ML-KEM algorithm, offering three hybrid combinations: X25519MLKEM768, SecP256r1MLKEM768, and SecP384r1_MLKEM1024. This feature is available in preview via the Windows Insider Program and will be rolled out to Windows 11 and Windows Server. Additionally, Windows cryptography APIs now support composite ML-KEM and ML-DSA algorithms, which are NIST-approved standards for key exchange and digital signatures, enhancing security by requiring multiple components to be compromised. Microsoft emphasizes the importance of establishing new Certification Authorities (CAs) for implementing post-quantum certificate issuance, as existing CAs cannot be upgraded. The introduction of ML-DSA support within ADCS allows organizations to counter HNDL risks associated with long-lived data. Organizations are encouraged to inventory their use of public-key cryptography, prioritize systems protecting sensitive data, and test hybrid and composite approaches in non-production environments to facilitate a smooth transition to quantum-safe cryptography.

Concerns about the Russian messaging application Max have grown due to vulnerabilities and surveillance features identified by IT specialists. An analysis revealed that Max can disable encryption on conversations with a single command and includes a forced-update feature that restricts user communication until the app is updated. Max collects extensive user data, including a list of installed applications and checks for VPNs, and has the ability to disable TLS session validation. Additionally, a version of Max included a neural network for speech recognition, although these features were later removed. Despite these concerns, VK, the parent company of Max, reported rapid user growth, surpassing 120 million users as of early May, with a daily reach of 68 million users. Many users are switching from Telegram to Max due to accessibility issues with Telegram and pressure from authorities. Major mobile carriers in Russia have collaborated with VK to send authentication messages through Max, further embedding the app in users' daily lives. However, Max has faced challenges in becoming a primary source for news and entertainment, hosting around 300,000 public channels compared to Telegram's 1.6 million, which has hindered advertising growth and led to an increase in scams.

On April 30, 2026, Microsoft Defender misclassified two legitimate DigiCert root certificates as a severe threat, specifically Trojan:Win32/Cerdigent.A!dha, leading to their quarantine and disrupting SSL/TLS validation across affected endpoints. This misclassification was a result of new malware detections introduced by Microsoft in response to concerns over compromised certificates from a DigiCert breach. The false-positive alerts were triggered by the registry entries of the two trusted root certificates, which are crucial for validating SSL/TLS sessions. Microsoft later acknowledged the error and adjusted the alert logic. There was no actual compromise of the DigiCert certificates, as administrators confirmed that the certificate hashes matched the official values. The misclassification stemmed from a failure to properly constrain the detection to only revoked end-entity signing certificates related to a separate incident. This incident follows a pattern of Microsoft Defender misidentifying legitimate software as malicious, as seen in a 2022 incident where Microsoft Office was flagged as a virus. Organizations with restrictive update policies may continue to face SSL/TLS validation failures until they deploy the corrective Security Intelligence version or manually restore the DigiCert roots.

A fraud network called FEMITBOT has emerged, using Telegram's Mini App feature to conduct investment scams and distribute malware. Identified by the research firm CTM360, the network operates through API responses and presents itself as organized. The scams involve Telegram Mini Apps that display phishing pages, fake dashboards showing fictitious earnings, and urgency tactics to pressure users into making quick decisions. FEMITBOT mimics well-known brands like Apple and Coca-Cola to enhance credibility and disseminates Android malware disguised as legitimate applications. The operation is highly organized, utilizing marketing tools to optimize their scams. Users are warned to be cautious of bots requesting deposits before granting access to funds.
