🔧 Remediation Steps (English)
1. IMMEDIATE ACTIONS:
- Identify all instances of Adobe Substance 3D Designer versions 15.1.0 and earlier in your environment
- Restrict file opening from untrusted sources until patching is complete
- Brief users on the risks of opening suspicious 3D design files from unknown sources
2. PATCHING GUIDANCE:
- Update Adobe Substance 3D Designer to version 15.2.0 or later immediately
- Prioritize patching for systems handling sensitive design projects
- Verify patch installation through Adobe's version verification tools
3. COMPENSATING CONTROLS (if immediate patching not possible):
- Implement application whitelisting to restrict Designer execution
- Use file integrity monitoring on design file directories
- Disable Designer on systems not requiring active use
- Implement network segmentation for design workstations
4. DETECTION RULES:
- Monitor for unexpected child processes spawned by Substance3D.exe
- Alert on file access patterns indicating malicious file handling
- Track Designer process memory allocation anomalies
- Log all file open operations with .sbs or related design file extensions from external sources
🔧 خطوات المعالجة (العربية)
1. الإجراءات الفورية:
- تحديد جميع نسخ Adobe Substance 3D Designer الإصدار 15.1.0 وما قبله في بيئتك
- تقييد فتح الملفات من مصادر غير موثوقة حتى اكتمال التصحيح
- إحاطة المستخدمين بمخاطر فتح ملفات التصميم ثلاثي الأبعاد المريبة من مصادر غير معروفة
2. إرشادات التصحيح:
- تحديث Adobe Substance 3D Designer إلى الإصدار 15.2.0 أو أحدث فوراً
- إعطاء الأولوية للتصحيح على الأنظمة التي تتعامل مع مشاريع تصميم حساسة
- التحقق من تثبيت التصحيح من خلال أدوات التحقق من الإصدار من Adobe
3. الضوابط البديلة (إذا لم يكن التصحيح الفوري ممكناً):
- تطبيق قائمة بيضاء للتطبيقات لتقييد تنفيذ Designer
- استخدام مراقبة سلامة الملفات على دلائل ملفات التصميم
- تعطيل Designer على الأنظمة التي لا تتطلب استخدام نشط
- تطبيق تقسيم الشبكة لمحطات عمل التصميم
4. قواعد الكشف:
- مراقبة العمليات الفرعية غير المتوقعة التي يتم إطلاقها بواسطة Substance3D.exe
- تنبيهات على أنماط الوصول إلى الملفات التي تشير إلى معالجة ملفات ضارة
- تتبع شذوذ تخصيص ذاكرة عملية Designer
- تسجيل جميع عمليات فتح الملفات باستخدام امتدادات .sbs أو ملفات تصميم ذات صلة من مصادر خارجية
