I just finished developing comprehensive YARA rules for the critical WSUS vulnerability CVE-2025-59287 (CVSS 9.8) that's being actively exploited in the wild.

What these YARA rules detect:

• WSUS API exploitation attempts (/ClientWebService, /SimpleAuthWebService)

• BinaryFormatter deserialization attacks

• Shellcode patterns & memory corruption attempts

• Suspicious network activity on ports 8530/8531

• Configuration tampering in WSUS services

Why I built this:
As a security researcher, I noticed many organizations were struggling to detect exploitation attempts beyond just applying the Microsoft patch. These rules provide that additional layer of visibility.

Key features:

• Low false-positive rate (tested against enterprise environments)

• Real-time detection capability

• SIEM integration ready

• Covers multiple exploitation vectors

Quick start:

yara -r CVE_2025_59287_WSUS_Rules.yar /target_directory

The rules are completely free - just trying to help the community stay protected against this critical vulnerability. Let me know if you find them useful or have suggestions for improvement!

Discussion points:

• How is your organization handling CVE-2025-59287 detection?

• Anyone else working on detection rules for this?

• What other critical CVEs need better detection coverage?

Proof of effectiveness available in the GitHub repository with sample detection logs.
