🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all instances of Adobe Substance3D Stager in your environment using asset management tools
2. Restrict file opening permissions for Substance3D to trusted sources only
3. Implement user awareness training on not opening suspicious .ssg or project files from untrusted sources
4. Disable Substance3D if not actively required

PATCHING GUIDANCE:
1. Update to Adobe Substance3D Stager version 3.1.8 or later immediately
2. Verify patch installation through Adobe's version check utility
3. Test patches in non-production environment before enterprise deployment
4. Prioritize patching for users handling external design files

COMPENSATING CONTROLS (if immediate patching not possible):
1. Implement application whitelisting to restrict Substance3D execution
2. Use file integrity monitoring on Substance3D installation directories
3. Isolate affected systems from sensitive networks
4. Monitor for suspicious process creation from Substance3D processes

DETECTION RULES:
1. Monitor for Substance3D.exe spawning unexpected child processes (cmd.exe, powershell.exe, rundll32.exe)
2. Alert on file access patterns indicating out-of-bounds memory operations
3. Track unusual network connections initiated from Substance3D processes
4. Monitor for modifications to system files or registry from Substance3D context
5. Implement YARA rules for malicious .ssg project files with suspicious embedded content
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع نسخ Adobe Substance3D Stager في بيئتك باستخدام أدوات إدارة الأصول
2. تقييد صلاحيات فتح الملفات لـ Substance3D من مصادر موثوقة فقط
3. تنفيذ تدريب الوعي الأمني للمستخدمين بعدم فتح ملفات مريبة من مصادر غير موثوقة
4. تعطيل Substance3D إذا لم يكن مطلوباً بشكل نشط

إرشادات التصحيح:
1. التحديث إلى Adobe Substance3D Stager الإصدار 3.1.8 أو أحدث فوراً
2. التحقق من تثبيت التصحيح من خلال أداة فحص الإصدار من Adobe
3. اختبار التصحيحات في بيئة غير الإنتاج قبل النشر على مستوى المؤسسة
4. إعطاء الأولوية لتصحيح المستخدمين الذين يتعاملون مع ملفات التصميم الخارجية

الضوابط البديلة (إذا لم يكن التصحيح الفوري ممكناً):
1. تنفيذ قائمة بيضاء للتطبيقات لتقييد تنفيذ Substance3D
2. استخدام مراقبة سلامة الملفات على مجلدات تثبيت Substance3D
3. عزل الأنظمة المتأثرة عن الشبكات الحساسة
4. مراقبة إنشاء العمليات المريبة من عمليات Substance3D

قواعد الكشف:
1. مراقبة Substance3D.exe لإنشاء عمليات فرعية غير متوقعة
2. تنبيهات على أنماط الوصول إلى الملفات التي تشير إلى عمليات الذاكرة خارج الحدود
3. تتبع الاتصالات الشبكية غير العادية من عمليات Substance3D
4. مراقبة التعديلات على ملفات النظام من سياق Substance3D
