🔧 Remediation Steps (English)
Immediate Actions:
1. Inventory all instances of Adobe Substance3D Stager across your organization and identify version numbers
2. Restrict user access to Substance3D Stager until patching is available
3. Implement user awareness training emphasizing the dangers of opening files from untrusted sources
4. Disable file associations for Substance3D project files if not actively required
Compensating Controls:
1. Implement application whitelisting to restrict Substance3D Stager execution
2. Deploy endpoint detection and response (EDR) solutions with behavioral monitoring for suspicious process creation
3. Use file integrity monitoring on directories containing Substance3D projects
4. Implement network segmentation to isolate systems running Substance3D from critical infrastructure
5. Enable Windows Defender Application Guard or similar sandboxing for file opening operations
6. Monitor for suspicious child processes spawned by Substance3D Stager
Detection Rules:
1. Alert on Substance3D Stager process creation with suspicious child processes
2. Monitor for unusual memory access patterns or heap corruption indicators
3. Track file access to Substance3D project files from unexpected sources
4. Monitor for code execution from temporary directories following Substance3D file operations
Patching:
1. Monitor Adobe security advisories for patch availability
2. Establish a rapid deployment process for when patches become available
3. Consider upgrading to newer versions once patches are released
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. قم بحصر جميع نسخ Adobe Substance3D Stager عبر مؤسستك وحدد أرقام الإصدارات
2. قيّد وصول المستخدمين إلى Substance3D Stager حتى تتوفر الرقع
3. نفّذ تدريباً على الوعي الأمني للمستخدمين يؤكد على مخاطر فتح الملفات من مصادر غير موثوقة
4. عطّل ارتباطات الملفات لملفات مشاريع Substance3D إذا لم تكن مطلوبة بنشاط
الضوابط التعويضية:
1. طبّق قائمة بيضاء للتطبيقات لتقييد تنفيذ Substance3D Stager
2. نشّر حلول الكشف والاستجابة للنقاط الطرفية مع المراقبة السلوكية لإنشاء العمليات المريبة
3. استخدم مراقبة سلامة الملفات على الدلائل التي تحتوي على مشاريع Substance3D
4. طبّق تقسيم الشبكة لعزل الأنظمة التي تقوم بتشغيل Substance3D عن البنية التحتية الحرجة
5. فعّل Windows Defender Application Guard أو حلول حماية مماثلة للعمليات الرملية
6. راقب العمليات الفرعية المريبة التي يتم إنشاؤها بواسطة Substance3D Stager
قواعد الكشف:
1. تنبيهات عند إنشاء عملية Substance3D Stager مع عمليات فرعية مريبة
2. مراقبة أنماط الوصول إلى الذاكرة غير العادية أو مؤشرات تلف الكومة
3. تتبع الوصول إلى ملفات مشاريع Substance3D من مصادر غير متوقعة
4. مراقبة تنفيذ الأكواد من الدلائل المؤقتة بعد عمليات ملفات Substance3D
التصحيح:
1. راقب إشعارات أمان Adobe لتوفر الرقع
2. أنشئ عملية نشر سريعة عند توفر الرقع
3. فكّر في الترقية إلى إصدارات أحدث بمجرد إصدار الرقع
