🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all TerraMaster NAS devices in your environment and document their network locations and data criticality
2. Isolate affected TerraMaster devices from production networks immediately or restrict network access to trusted sources only
3. Implement network segmentation to limit lateral movement if compromise occurs
4. Enable comprehensive logging and monitoring on TerraMaster devices
PATCHING:
5. Apply the latest TerraMaster OS security patches immediately from official TerraMaster support channels
6. Verify patch installation and reboot devices to ensure updates are active
7. Change all default and weak credentials on TerraMaster devices
COMPENSATING CONTROLS (if patching delayed):
8. Implement firewall rules to restrict access to TerraMaster management interfaces (typically ports 8080, 8443) to authorized IP ranges only
9. Disable remote access features if not required for operations
10. Deploy Web Application Firewall (WAF) rules to detect exploitation attempts
DETECTION:
11. Monitor for suspicious HTTP/HTTPS requests to TerraMaster devices with command injection patterns
12. Alert on unexpected process execution from TerraMaster services
13. Monitor for unusual outbound connections from TerraMaster devices
14. Review TerraMaster access logs for unauthenticated access attempts
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حدد جميع أجهزة TerraMaster NAS في بيئتك وقثق مواقعها على الشبكة وأهمية البيانات
2. عزل أجهزة TerraMaster المتأثرة عن شبكات الإنتاج فوراً أو تقييد الوصول إلى الشبكة للمصادر الموثوقة فقط
3. تنفيذ تقسيم الشبكة لتحديد الحركة الجانبية في حالة الاختراق
4. تفعيل السجلات الشاملة والمراقبة على أجهزة TerraMaster
التصحيح:
5. تطبيق أحدث تصحيحات أمان نظام TerraMaster OS فوراً من قنوات دعم TerraMaster الرسمية
6. التحقق من تثبيت التصحيح وإعادة تشغيل الأجهزة للتأكد من تفعيل التحديثات
7. تغيير جميع بيانات الاعتماد الافتراضية والضعيفة على أجهزة TerraMaster
الضوابط البديلة (إذا تأخر التصحيح):
8. تنفيذ قواعد جدار الحماية لتقييد الوصول إلى واجهات إدارة TerraMaster (عادة المنافذ 8080، 8443) إلى نطاقات IP المصرح بها فقط
9. تعطيل ميزات الوصول البعيد إذا لم تكن مطلوبة للعمليات
10. نشر قواعد جدار تطبيقات الويب (WAF) للكشف عن محاولات الاستغلال
الكشف:
11. مراقبة طلبات HTTP/HTTPS المريبة إلى أجهزة TerraMaster بأنماط حقن الأوامر
12. التنبيه على تنفيذ العمليات غير المتوقعة من خدمات TerraMaster
13. مراقبة الاتصالات الخارجية غير المعتادة من أجهزة TerraMaster
14. مراجعة سجلات الوصول إلى TerraMaster لمحاولات الوصول غير المصرح بها
