🔧 Remediation Steps (English)
Immediate Actions:
1. Identify all systems running Adobe Substance 3D Designer versions 15.1.0 or earlier through asset inventory and software audit tools
2. Restrict user access to Substance 3D Designer until patching is complete
3. Implement file-level restrictions preventing opening of untrusted .spp, .sbsar, and other Substance 3D file formats from external sources
Patching Guidance:
1. Update Adobe Substance 3D Designer to version 15.2.0 or later immediately
2. Prioritize patching for systems handling sensitive design projects or connected to corporate networks
3. Test patches in non-production environments before enterprise deployment
Compensating Controls (if immediate patching not possible):
1. Disable Substance 3D Designer on non-essential systems
2. Implement application whitelisting to prevent unauthorized code execution
3. Run Substance 3D Designer in sandboxed environments or virtual machines
4. Restrict file sharing of Substance 3D project files to trusted internal sources only
5. Implement network segmentation isolating design workstations from critical systems
Detection Rules:
1. Monitor for unexpected child processes spawned by Substance3DDesigner.exe
2. Alert on file modifications in %APPDATA%\Adobe\Substance3D directories
3. Track network connections initiated by Substance 3D Designer to external IP addresses
4. Log all file open operations for .spp and .sbsar files from external/removable media
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع الأنظمة التي تقوم بتشغيل Adobe Substance 3D Designer الإصدارات 15.1.0 والأقدم من خلال أدوات جرد الأصول وتدقيق البرامج
2. تقييد وصول المستخدمين إلى Substance 3D Designer حتى اكتمال التصحيح
3. تطبيق قيود على مستوى الملفات لمنع فتح تنسيقات ملفات Substance 3D غير الموثوقة من مصادر خارجية
إرشادات التصحيح:
1. تحديث Adobe Substance 3D Designer إلى الإصدار 15.2.0 أو أحدث فوراً
2. إعطاء الأولوية لتصحيح الأنظمة التي تتعامل مع مشاريع تصميم حساسة أو المتصلة بالشبكات المؤسسية
3. اختبار التصحيحات في بيئات غير الإنتاج قبل النشر على مستوى المؤسسة
الضوابط البديلة (إذا لم يكن التصحيح الفوري ممكناً):
1. تعطيل Substance 3D Designer على الأنظمة غير الأساسية
2. تطبيق القائمة البيضاء للتطبيقات لمنع تنفيذ الأكواد غير المصرح بها
3. تشغيل Substance 3D Designer في بيئات معزولة أو آلات افتراضية
4. تقييد مشاركة ملفات مشاريع Substance 3D للمصادر الداخلية الموثوقة فقط
5. تطبيق تقسيم الشبكة لعزل محطات العمل الخاصة بالتصميم عن الأنظمة الحرجة
قواعد الكشف:
1. مراقبة العمليات الفرعية غير المتوقعة التي يتم إطلاقها بواسطة Substance3DDesigner.exe
2. التنبيه على تعديلات الملفات في أدلة %APPDATA%\Adobe\Substance3D
3. تتبع الاتصالات الشبكية التي يبدأها Substance 3D Designer إلى عناوين IP خارجية
4. تسجيل جميع عمليات فتح الملفات لملفات .spp و .sbsar من وسائط خارجية/قابلة للإزالة
