🔧 Remediation Steps (English)
Immediate Actions:
1. Inventory all Microsoft Office Excel installations across the organization
2. Restrict Excel file access to trusted users only; implement principle of least privilege
3. Disable Excel macros organization-wide until patch availability
4. Implement file integrity monitoring on critical Excel documents

Compensating Controls:
5. Isolate systems handling sensitive data in Excel from general networks
6. Require multi-factor authentication for accessing systems with Excel
7. Deploy Data Loss Prevention (DLP) policies to monitor Excel file access and transfers
8. Enable audit logging for all Excel file opens and modifications
9. Conduct user awareness training on not opening untrusted Excel files

Detection Rules:
10. Monitor for unusual Excel process behavior (memory access patterns, unexpected child processes)
11. Alert on Excel files accessed from unusual locations or by unusual users
12. Track failed Excel file operations that may indicate exploitation attempts
13. Monitor for data exfiltration following Excel file access

Patching Strategy:
14. Subscribe to Microsoft security advisories for patch release notifications
15. Establish expedited patching process for Excel once patch becomes available
16. Test patch in isolated environment before enterprise deployment
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حصر جميع تثبيتات Microsoft Office Excel عبر المنظمة
2. تقييد وصول ملفات Excel للمستخدمين الموثوقين فقط؛ تطبيق مبدأ الحد الأدنى من الامتيازات
3. تعطيل وحدات الماكرو في Excel على مستوى المنظمة حتى توفر التصحيح
4. تطبيق مراقبة سلامة الملفات على مستندات Excel الحرجة

الضوابط التعويضية:
5. عزل الأنظمة التي تتعامل مع البيانات الحساسة في Excel عن الشبكات العامة
6. طلب المصادقة متعددة العوامل للوصول إلى الأنظمة التي تحتوي على Excel
7. نشر سياسات منع فقدان البيانات (DLP) لمراقبة وصول ملفات Excel والتحويلات
8. تفعيل تسجيل التدقيق لجميع عمليات فتح وتعديل ملفات Excel
9. إجراء تدريب التوعية للمستخدمين بعدم فتح ملفات Excel غير الموثوقة

قواعد الكشف:
10. مراقبة سلوك عملية Excel غير المعتاد (أنماط الوصول إلى الذاكرة، العمليات الفرعية غير المتوقعة)
11. التنبيه على ملفات Excel التي يتم الوصول إليها من مواقع غير معتادة أو من قبل مستخدمين غير معتادين
12. تتبع عمليات ملفات Excel الفاشلة التي قد تشير إلى محاولات استغلال
13. مراقبة تسرب البيانات بعد الوصول إلى ملف Excel

استراتيجية التصحيح:
14. الاشتراك في تنبيهات أمان Microsoft لإشعارات إصدار التصحيح
15. إنشاء عملية تصحيح معجلة لـ Excel بمجرد توفر التصحيح
16. اختبار التصحيح في بيئة معزولة قبل النشر على مستوى المؤسسة
