🔧 Remediation Steps (English)
1. IMMEDIATE ACTIONS:
- Identify all systems running Microvirt MEMU Play 3.7.0 or earlier versions
- Restrict local access to affected systems through access control lists
- Disable MEmusvc service if not actively required
- Implement application whitelisting on systems running MEMU Play
2. PATCHING GUIDANCE:
- Upgrade Microvirt MEMU Play to version 3.7.1 or later immediately
- Verify patch installation by checking service binary path in Registry (HKLM\SYSTEM\CurrentControlSet\Services\MEmusvc)
- Test patched systems in isolated environment before production deployment
3. COMPENSATING CONTROLS:
- Isolate MEMU Play systems on separate network segments
- Implement file integrity monitoring on system directories
- Use Windows AppLocker to prevent unauthorized executable execution
- Enable Windows Defender Application Guard for additional isolation
4. DETECTION RULES:
- Monitor for suspicious file creation in Program Files directories with names similar to legitimate Windows binaries
- Alert on MEmusvc service restart or modification events
- Track Registry modifications to HKLM\SYSTEM\CurrentControlSet\Services\MEmusvc
- Monitor for privilege escalation attempts from MEMU Play installation directory
🔧 خطوات المعالجة (العربية)
1. الإجراءات الفورية:
- تحديد جميع الأنظمة التي تقوم بتشغيل Microvirt MEMU Play 3.7.0 أو الإصدارات الأقدم
- تقييد الوصول المحلي للأنظمة المتأثرة من خلال قوائم التحكم في الوصول
- تعطيل خدمة MEmusvc إذا لم تكن مطلوبة بنشاط
- تنفيذ قائمة بيضاء للتطبيقات على الأنظمة التي تقوم بتشغيل MEMU Play
2. إرشادات التصحيح:
- ترقية Microvirt MEMU Play إلى الإصدار 3.7.1 أو أحدث على الفور
- التحقق من تثبيت التصحيح بفحص مسار ملف الخدمة في السجل
- اختبار الأنظمة المصححة في بيئة معزولة قبل نشرها في الإنتاج
3. الضوابط البديلة:
- عزل أنظمة MEMU Play على أجزاء شبكة منفصلة
- تنفيذ مراقبة سلامة الملفات على دلائل النظام
- استخدام Windows AppLocker لمنع تنفيذ الملفات التنفيذية غير المصرح بها
- تفعيل Windows Defender Application Guard للعزل الإضافي
4. قواعد الكشف:
- مراقبة إنشاء الملفات المريبة في دلائل Program Files بأسماء مشابهة للملفات التنفيذية الشرعية لـ Windows
- التنبيه على أحداث إعادة تشغيل أو تعديل خدمة MEmusvc
- تتبع تعديلات السجل على HKLM\SYSTEM\CurrentControlSet\Services\MEmusvc
- مراقبة محاولات تصعيد الامتيازات من دليل تثبيت MEMU Play
