🔧 Remediation Steps (English)
Immediate Actions:
1. Inventory all Windows workstations in your environment and document current patch levels
2. Restrict administrative and user privilege escalation capabilities through Group Policy
3. Implement application whitelisting to prevent unauthorized code execution
4. Monitor for patch announcements from Microsoft and the affected vendor
Compensating Controls (until patch available):
5. Enforce principle of least privilege - remove unnecessary user rights from domain accounts
6. Implement privileged access management (PAM) solutions for sensitive accounts
7. Enable Windows Defender Application Guard for high-risk users
8. Deploy endpoint detection and response (EDR) solutions to detect abnormal process behavior
Detection Rules:
9. Monitor Windows Event Logs for null pointer dereference exceptions (Event ID 1000)
10. Alert on unexpected application crashes in security event logs
11. Track failed privilege escalation attempts via Windows Security event logs
12. Once patch is available, verify deployment across all workstations within 30 days
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع محطات العمل التي تعمل بنظام Windows في بيئتك وتوثيق مستويات التصحيح الحالية
2. قيّد قدرات تصعيد الامتيازات الإدارية ومستخدم من خلال سياسة المجموعة
3. طبّق قائمة التطبيقات المسموحة لمنع تنفيذ الأكواد غير المصرح بها
4. راقب إعلانات التصحيحات من Microsoft والمورد المتأثر
الضوابط التعويضية (حتى توفر التصحيح):
5. طبّق مبدأ أقل امتياز - أزل الحقوق غير الضرورية من حسابات المجال
6. طبّق حلول إدارة الوصول المميز (PAM) للحسابات الحساسة
7. فعّل Windows Defender Application Guard للمستخدمين عالي المخاطر
8. نشّر حلول الكشف والاستجابة للنقاط النهائية (EDR) للكشف عن السلوك غير الطبيعي
قواعد الكشف:
9. راقب سجلات أحداث Windows للبحث عن استثناءات إلغاء المؤشر الفارغ (معرّف الحدث 1000)
10. أصدر تنبيهات عند توقف التطبيقات غير المتوقع في سجلات أحداث الأمان
11. تتبع محاولات تصعيد الامتيازات الفاشلة عبر سجلات أحداث أمان Windows
12. بمجرد توفر التصحيح، تحقق من النشر عبر جميع محطات العمل خلال 30 يوماً
