🔔 Microsoft has released updates to WinSqlite3.dll after third-party security tools began flagging the Windows core DLL as vulnerable to CVE-2025-6965. The company said the false positive affected Windows 10, Windows 11, and server editions through Windows Server 2025. Microsoft resolved the detection in updates released January 13, 2026 and later and urges users to install the latest patches. It also clarified WinSqlite3.dll is distinct from sqlite3.dll.

🛡️ Microsoft announced on 14 January that it has seized the infrastructure and website of RedVDS, a subscription-based cybercrime platform that rented disposable virtual machines and AI tools to facilitate phishing, business email compromise (BEC) and fraud. The service, available from about $24/month, has been linked to more than $40 million in losses in the US and nearly 190,000 victimised organisations worldwide. Legal partners in the US and the UK, with international law enforcement support, coordinated the takedown.

🔒Push Security discovered ConsentFix in December — a browser-native OAuth phishing technique that tricks victims into pasting a legitimate Microsoft authorization URL so attackers can exchange the code and hijack accounts. The campaign targeted pre-consented first-party Microsoft apps and legacy scopes to evade default logging and Conditional Access controls. Push and the security community have published hunting guidance and mitigations focused on logging, access restrictions, and browser-based detection.

⚠️ Pax8 confirmed it mistakenly emailed a CSV attachment on January 13 that contained internal pricing and Microsoft licensing data to fewer than 40 UK-based partners. Recipients reported the file listed about 56,000 entries covering roughly 1,800 partners, with fields including partner and customer IDs, SKUs, license counts, renewal dates, and booking details. Pax8 asked recipients to delete the message, required deletion confirmations, and said it launched an internal review. The company maintains the file did not contain personally identifiable information and that marketplace availability and security controls were not affected.

🔒 Microsoft released updates addressing over 100 CVEs on the first Patch Tuesday of 2026, including three zero-day vulnerabilities. CVE-2026-20805 is an actively exploited information-disclosure flaw in the Desktop Window Manager that can undermine ASLR; CVE-2026-21265 concerns a secure-boot certificate-expiration bypass affecting many devices; CVE-2023-31096 is an elevation-of-privilege in legacy Agere modem drivers that Microsoft is removing. Administrators should prioritize patching, review firmware and UEFI certificates, and audit hardware where updates may require manual acceptance.

⚠️ Microsoft confirmed a recent Windows 365 update is preventing some customers from signing in to their Cloud PC sessions. The disruption began Tuesday at 19:00 UTC after automated monitoring detected a spike in failed connection attempts, and engineers traced the problem to the update.

🛡️ Microsoft’s January 2026 Patch Tuesday addresses eight critical vulnerabilities and an actively exploited zero-day, with many high‑score flaws affecting Office and SharePoint. The Desktop Window Manager information-disclosure bug (CVE-2026-20805) is already being exploited and can leak memory to enable follow-on attacks. Other priorities include an RRAS heap overflow (CVE-2026-20868), Secure Boot certificate updates (CVE-2026-21265), and multiple NTFS and WinSock elevation issues. Administrators should accelerate patching, restrict local access, and monitor for suspicious activity.

🔒 Microsoft released January 2026 security updates addressing 113 vulnerabilities across Windows and supported products, including eight rated Critical.

Experts urge rapid, risk-based patching and careful BIOS/bootloader preparation.

🔒 Microsoft has begun automatically replacing expiring Secure Boot certificates on eligible Windows 11 24H2 and 25H2 systems via Windows Update. The rollout uses high-confidence device targeting and phased signals to ensure only devices with sufficient successful update telemetry receive the new certificates, while administrators can also deploy them using registry keys, WinCS, or Group Policy. Organizations are urged to inventory fleets, verify Secure Boot status, apply firmware updates as needed, and install the certificate updates before existing credentials expire to preserve Secure Boot and pre-boot patching.

🔒 Microsoft released the KB5073724 Extended Security Update for Windows 10, available to Windows 10 Enterprise LTSC and systems enrolled in the ESU program. Install via Settings → Windows Update by performing a manual “Check for Updates”; installs update and raises builds to 19045.6809 (Windows 10) and 19044.6809 (Enterprise LTSC 2021).

🔐 In a Deputy CISO post, Terrell Cox explains how Microsoft aligns privacy and security as complementary priorities, treating privacy as a human right across products from Microsoft 365 to Azure. The company enforces rigorous internal compliance—audits, cross‑functional reviews, and executive oversight—and limits data access through controls like Customer Lockbox and zero‑trust access. Microsoft highlights solutions such as Microsoft Entra, Entra ID, and Microsoft Purview to support data residency, classification, protection, and regulatory compliance.
