🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Inventory all Dreamweaver installations across the organization, including version numbers and user assignments
2. Restrict file opening from untrusted sources until patching is complete
3. Disable Dreamweaver auto-update features temporarily if they conflict with change management procedures
PATCHING GUIDANCE:
1. Download the latest Adobe Dreamweaver patch from Adobe's official security updates portal
2. Test patches in a non-production environment first, particularly for critical web development teams
3. Deploy patches to all affected systems within 72 hours of availability
4. Verify patch installation by checking Help > About Adobe Dreamweaver for version confirmation
COMPENSATING CONTROLS (if patching delayed):
1. Implement application whitelisting to restrict Dreamweaver execution to authorized users only
2. Use file integrity monitoring on .dwt, .html, .php, and other Dreamweaver project files
3. Restrict Dreamweaver network access via firewall rules to prevent C2 communication
4. Disable file preview features in email clients and file sharing platforms
DETECTION RULES:
1. Monitor for Dreamweaver process spawning child processes (cmd.exe, powershell.exe, bash)
2. Alert on Dreamweaver accessing suspicious file types (.exe, .dll, .scr, .vbs)
3. Track Dreamweaver network connections to non-standard ports (not 80, 443, 21)
4. Log all file modifications within Dreamweaver project directories with timestamps
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. حصر جميع تثبيتات Dreamweaver في المنظمة، بما في ذلك أرقام الإصدارات والمستخدمين المعينين
2. تقييد فتح الملفات من مصادر غير موثوقة حتى اكتمال التصحيح
3. تعطيل ميزات التحديث التلقائي لـ Dreamweaver مؤقتاً إذا تعارضت مع إجراءات إدارة التغيير
إرشادات التصحيح:

3. نشر التصحيحات على جميع الأنظمة المتأثرة خلال 72 ساعة من توفرها
4. التحقق من تثبيت التصحيح بفحص Help > About Adobe Dreamweaver للتأكد من رقم الإصدار
الضوابط البديلة (إذا تأخر التصحيح):
1. تطبيق قائمة بيضاء للتطبيقات لتقييد تنفيذ Dreamweaver للمستخدمين المصرح لهم فقط
2. استخدام مراقبة سلامة الملفات على ملفات .dwt و .html و .php ومشاريع Dreamweaver الأخرى
3. تقييد وصول شبكة Dreamweaver عبر قواعد جدار الحماية لمنع اتصالات C2
4. تعطيل ميزات معاينة الملفات في عملاء البريد الإلكتروني ومنصات مشاركة الملفات
قواعد الكشف:
1. مراقبة عملية Dreamweaver التي تولد عمليات فرعية (cmd.exe, powershell.exe, bash)
2. تنبيه عند وصول Dreamweaver إلى أنواع ملفات مريبة (.exe, .dll, .scr, .vbs)
3. تتبع اتصالات شبكة Dreamweaver بمنافذ غير قياسية (ليس 80، 443، 21)
4. تسجيل جميع تعديلات الملفات داخل دلائل مشاريع Dreamweaver مع الطوابع الزمنية
