Episode 02 Microsoft Defender Found Vulnerable OpenSSL — Where Is It Installed?

🚨 Microsoft Defender detected vulnerable OpenSSL libraries on Windows 11 devices. But which applications actually installed them? In Episode 02 of our Microsoft Defender XDR — Real-World SOC Labs & Troubleshooting series, we'll investigate vulnerable OpenSSL libraries, identify their file paths, and discover which applications are associated with them. Using a hands-on Microsoft Defender lab, we'll examine 15 detected file entries across two Windows 11 endpoints and explain why fixing a vulnerable DLL isn't always as simple as replacing one file. 🔍 What You'll Learn: ✅ How to locate vulnerable software recommendations in Microsoft Defender XDR ✅ How to investigate the Vulnerable files tab ✅ How to identify OpenSSL library file paths ✅ How to recognize applications associated with vulnerable libraries ✅ How to examine different OpenSSL versions ✅ Why multiple applications may bundle their own OpenSSL libraries ✅ Why manually deleting or replacing vulnerable DLL files can cause problems ✅ How to plan safe, application-level remediation 💻 Applications identified during our investigation: Microsoft Office Hub Microsoft Photos Microsoft Paint Microsoft OneDrive 🛡️ Investigation Details: Platform: Microsoft Defender XDR Target software: OpenSSL Detected file entries: 15 Affected endpoints: 2 Windows 11 devices Recommendation: Update owning apps: vulnerable OpenSSL libraries detected Important: This episode focuses on identifying vulnerable files and understanding application ownership. No updates are deployed during the demonstration. We'll explore remediation planning and coordination in a future episode. 🎬 Watch the Series: Episode 01 — Critical CVE Found in Defender: Is Your Device Really at Risk?
