New Windows Zero-Day Vulnerability Exposes NTLM Credentials – Unofficial Patch Now Available

A zero-day vulnerability has been identified in the Windows operating system, affecting versions from Windows 7 and Server 2008 R2 to Windows 11 v24H2 and Server 2025. This vulnerability allows attackers to obtain NTLM credentials by tricking users into opening malicious files in Windows Explorer. Microsoft has been notified, and while there is no official CVE number yet, an unofficial patch is available through 0patch. The flaw is similar to previous vulnerabilities related to NTLM hash disclosures but has not been widely discussed. To exploit it, attackers need network access to the victim's system or a way to relay stolen credentials. 0patch has created micropatches for all affected Windows versions, which are available for free until Microsoft provides an official fix. This is the fourth zero-day vulnerability reported by 0patch recently, with previous vulnerabilities including those in Windows Theme files and the Mark of the Web issue on Server 2012. 0patch also offers patches for NTLM-related vulnerabilities that Microsoft has classified as “wont fix.” Users can create a free account with 0patch for automatic protection against these vulnerabilities. Micropatches are available for various Windows versions, including both legacy and currently supported systems, and will remain free until an official Microsoft fix is released.

First signs of Windows 11 25H2? Here’s what we know so far

Users are encouraged to upgrade to Windows 11 24H2 as support for Windows 10 is ending. Some users are hesitant due to reported issues with Bluetooth audio, File Explorer glitches, and system crashes, leading them to consider waiting for the anticipated Windows 11 25H2 update. Microsoft has announced advancements in the Dev Channel to the "26200 series builds," which are based on the 24H2 framework, but has not confirmed the 25H2 update. The 26200 build series indicates potential significant changes, but it is unclear whether 25H2 will be an enablement package or a full OS transition. Microsoft has not provided a release timeline for 25H2, but historically, major updates are expected in September or October, coinciding with the end of Windows 10 support.

The six-step countdown to Windows 10 end of life

The end of Windows 10 support is approaching, prompting IT decision-makers to consider transitioning to Windows 11. This transition allows organizations to modernize hardware, rethink client infrastructure, and adopt advanced management technologies. Continuing to use Windows 10 can lead to high maintenance costs and potential performance issues with M365/Office applications after October 14, 2025. Upgrading to AI-capable PCs can enhance operational efficiencies, while unsupported systems expose organizations to cyber threats and compliance risks. Windows 11 Pro offers improved security features, and upgrading aligns with sustainability goals through practices like Asset Recovery Services. A well-planned transition strategy is essential to avoid rushed decisions and ensure compatibility and training. Delaying the upgrade poses risks, including financial burdens from extended security update fees.

Why Windows End of Life deadlines require a change of mindset

Organizations are increasingly concerned about the impending End of Life (EoL) deadlines for Microsoft applications and systems, with many large enterprises seeking advice on upgrading Microsoft Teams and legacy technologies. Key products like Windows 10, Office 2019, and Exchange Server 2019 will reach end-of-support by October 2025, prompting urgent decisions to mitigate operational, security, and compliance risks. Statistics show that as of January 2025, Windows 10 and Windows 11 each hold a 49.4% market share in the UK, indicating that half of all desktops are nearing their EoL. Dedicated EoL hotlines have been established to assist companies with migration strategies for applications approaching EoL, emphasizing the need for internal resources and expertise to manage transitions effectively. The industry-standard ‘R approach’ includes methods like rehosting and retiring applications to facilitate migrations. Organizations are encouraged to migrate out-of-support applications into secure environments rather than directly altering them, while remaining vigilant about EoL deadlines and the complexities of legacy systems.

CISA Warns of Microsoft Windows Management Console (MMC) Vulnerability Exploited in Wild

CISA has identified a critical vulnerability in Microsoft Windows Management Console (MMC), designated as CVE-2025-26633, which allows remote attackers to execute arbitrary code due to improper input sanitization. This vulnerability is included in CISA's Known Exploited Vulnerabilities catalog, and federal agencies must address it by April 2, 2025, as per Binding Operational Directive 22-01. Microsoft has released an out-of-band patch on March 10, 2025, to improve input validation in mmc.exe. Organizations are advised to prioritize patching, restrict MMC access, and monitor for exploitation.

CISA Alerts on Active Exploitation of Cisco Small Business Router Flaw

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a critical alert about a command injection vulnerability (CVE-2023-20118) affecting Cisco Small Business RV Series Routers, which are end-of-life. This vulnerability, rated 6.5 on the CVSSv3.1 scale, allows authenticated attackers to execute arbitrary commands with root privileges. The affected models include RV016, RV042, RV042G, RV082, RV320, and RV325, running firmware versions released before April 2023. Cisco will not provide patches for these devices. CISA mandates that federal agencies either implement mitigations or stop using the routers by March 24, 2025. Private organizations are also encouraged to address the issue, especially due to exploitation attempts linked to the PolarEdge botnet campaign. Administrators are advised to restrict administrative access, monitor logs for unusual activity, and consider decommissioning affected devices. The continued use of unpatched routers poses significant risks to critical infrastructure, particularly in small business and remote work environments.

APAC enterprises shifting towards open source in database strategies

Enterprises in the Asia-Pacific region are increasingly transitioning from proprietary databases to open-source alternatives, with PostgreSQL being favored due to high licensing costs and vendor dependencies. IT leaders are reassessing database strategies to meet performance, cost, and scalability needs, particularly for applications requiring transactional, analytical, and AI workloads. Hybrid IT models are gaining traction, especially in countries like Singapore, Indonesia, and the Philippines, while Japan and Korea show strong on-premises demand, and India is moving away from legacy systems due to cost pressures. PostgreSQL is evolving to support hybrid IT and emerging workloads, including AI and analytics, with enhancements like lakehouse architecture for managing structured and unstructured data and the introduction of pgvector for AI applications. Data sovereignty regulations are prompting enterprises to deploy PostgreSQL in hybrid cloud environments to balance control and scalability. EDB has developed a hybrid control plane for unified management across on-premises and cloud deployments. Many enterprises are opting for a gradual transition to PostgreSQL due to legacy dependencies and operational risks, often starting with specific use cases before migrating legacy workloads. An example includes an insurance company in Hong Kong that migrated from Oracle to PostgreSQL, achieving reduced costs and improved performance. Successful migration depends on database mobility and application portability, with EDB planning to integrate GPU support and develop tools for faster AI application deployment, with expectations for rollout by the second quarter of 2025.
