🔧 Remediation Steps (English)
1. IMMEDIATE ACTIONS:
- Identify all systems running Adobe Substance 3D Designer versions 15.0.3 or earlier
- Restrict user access to opening untrusted or external design files until patching is complete
- Implement file transfer controls for .spp, .sbsar, and related Substance file formats from external sources
2. PATCHING GUIDANCE:
- Update Adobe Substance 3D Designer to version 15.0.4 or later immediately
- Prioritize patching for systems handling external design files or client deliverables
- Verify patch installation through Adobe's version verification tools
3. COMPENSATING CONTROLS (if immediate patching not possible):
- Disable file opening from untrusted sources; require IT review of external design files
- Run Substance 3D Designer in sandboxed environments or restricted user accounts
- Implement application whitelisting to prevent unauthorized code execution
- Monitor process execution from Substance3D processes for anomalous behavior
4. DETECTION RULES:
- Monitor for Substance3D.exe spawning child processes (cmd.exe, powershell.exe, etc.)
- Alert on file access patterns indicating out-of-bounds memory operations
- Track failed and successful file open operations for suspicious file types
- Monitor for unusual network connections initiated by Substance3D processes
🔧 خطوات المعالجة (العربية)
1. الإجراءات الفورية:
- تحديد جميع الأنظمة التي تقوم بتشغيل Adobe Substance 3D Designer الإصدارات 15.0.3 أو أقدم
- تقييد وصول المستخدمين إلى فتح الملفات غير الموثوقة أو الخارجية حتى اكتمال التصحيح
- تطبيق عناصر تحكم نقل الملفات لتنسيقات Substance المختلفة من مصادر خارجية
2. إرشادات التصحيح:
- تحديث Adobe Substance 3D Designer إلى الإصدار 15.0.4 أو أحدث فوراً
- إعطاء الأولوية للتصحيح على الأنظمة التي تتعامل مع ملفات التصميم الخارجية
- التحقق من تثبيت التصحيح من خلال أدوات التحقق من الإصدار من Adobe
3. عناصر التحكم البديلة (إذا لم يكن التصحيح الفوري ممكناً):
- تعطيل فتح الملفات من مصادر غير موثوقة؛ طلب مراجعة تكنولوجيا المعلومات للملفات الخارجية
- تشغيل Substance 3D Designer في بيئات معزولة أو حسابات مستخدمين مقيدة
- تطبيق قائمة بيضاء للتطبيقات لمنع تنفيذ الأكواد غير المصرح بها
- مراقبة تنفيذ العمليات من عمليات Substance3D للكشف عن السلوك الشاذ
4. قواعد الكشف:
- مراقبة Substance3D.exe لإنشاء عمليات فرعية (cmd.exe, powershell.exe, إلخ)
- تنبيهات على أنماط الوصول إلى الملفات التي تشير إلى عمليات الذاكرة خارج الحدود
- تتبع عمليات فتح الملفات الفاشلة والناجحة لأنواع ملفات مريبة
- مراقبة الاتصالات الشبكية غير العادية التي تبدأها عمليات Substance3D
