Microsoft’s February 2025 Patch Tuesday addresses a total of 63 security flaws across various products, including two zero-day vulnerabilities under active exploitation. These zero-day bugs reportedly allow attackers to escalate privileges on Windows systems without user interaction. The updates cover an extensive range of Microsoft software, from Windows OS components and Exchange Server to developer tools and Microsoft Office.
Cybersecurity researchers urge organisations and individual users alike to prioritise these patches, emphasising that the zero-day exploits pose a particularly high risk. Microsoft has acknowledged these active exploits and recommends applying the updates immediately to minimise potential compromise. Although no confirmed widespread attacks have been publicly disclosed yet, experts advise maintaining vigilance, as unpatched systems are prime targets for cybercriminals.

Microsoft’s February 2025 Patch Tuesday: 63 Flaws Fixed
Microsoft has released its latest round of security patches, collectively fixing 63 vulnerabilities in various software products. Among these updates, two zero-day flaws are of particular concern, as they are already being exploited in the wild.
What’s Been Patched?
• Windows OS Components: Several Windows versions received fixes for privilege escalation vulnerabilities, ensuring malicious actors cannot gain unauthorised higher-level access.
• Exchange Server: Administrators are advised to patch immediately to prevent potentially severe breaches of corporate email systems.
• Office and Developer Tools: Updates include security enhancements for products like Microsoft Office, Visual Studio, and other widely used Microsoft applications.
Why It Matters
Two of the flaws patched in this update cycle are under active attack. These zero-day vulnerabilities allow cybercriminals to exploit unpatched systems quickly and silently. By issuing patches for these critical weaknesses, Microsoft aims to block attackers from infiltrating both business and personal environments.
Action for Users
• Install Patches Promptly: Whether you are an IT administrator or a home user, apply these updates as soon as possible.
• Monitor Threat Advisories: Stay informed about any emerging exploits connected to these vulnerabilities.
• Review System Logs: Keep an eye on activity logs or security notifications to catch suspicious behaviour early.
By proactively updating, businesses and end users can reduce their risk of compromise and help prevent widespread malicious activity.
