🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Apple iOS, iPadOS, and macOS devices in your organization
2. Disable WebKit-based browsing on critical systems until patching is complete
3. Block access to untrusted websites and implement web filtering
4. Alert users to avoid clicking suspicious links or visiting untrusted websites
PATCHING GUIDANCE:
1. Deploy iOS/iPadOS security updates to all devices (iOS 14.4 or later)
2. Update macOS to patched versions (macOS 11.2.3 or later)
3. Prioritize devices used by finance, government, and healthcare personnel
4. Test patches in non-production environment first
COMPENSATING CONTROLS:
1. Implement Mobile Device Management (MDM) to enforce security policies
2. Deploy endpoint detection and response (EDR) solutions
3. Monitor for suspicious process execution and network connections
4. Restrict JavaScript execution in browsers where possible
5. Implement network segmentation to limit lateral movement
DETECTION RULES:
1. Monitor for unexpected Safari/WebKit process spawning child processes
2. Alert on unusual network connections from Safari process
3. Track file creation in temporary directories from browser processes
4. Monitor for code execution attempts from WebKit rendering processes
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع أجهزة Apple iOS و iPadOS و macOS في مؤسستك
2. تعطيل التصفح القائم على WebKit على الأنظمة الحرجة حتى اكتمال التحديث
3. حظر الوصول إلى المواقع غير الموثوقة وتطبيق تصفية الويب
4. تنبيه المستخدمين لتجنب النقر على الروابط المريبة أو زيارة المواقع غير الموثوقة
إرشادات التصحيح:
1. نشر تحديثات أمان iOS/iPadOS على جميع الأجهزة (iOS 14.4 أو أحدث)
2. تحديث macOS إلى الإصدارات المصححة (macOS 11.2.3 أو أحدث)
3. إعطاء الأولوية للأجهزة التي يستخدمها موظفو المالية والحكومة والرعاية الصحية
4. اختبار التحديثات في بيئة غير إنتاجية أولاً
الضوابط البديلة:
1. تطبيق إدارة الأجهزة المحمولة (MDM) لفرض سياسات الأمان
2. نشر حلول الكشف والاستجابة للنقاط النهائية (EDR)
3. مراقبة تنفيذ العمليات والاتصالات الشبكية المريبة
4. تقييد تنفيذ JavaScript في المتصفحات حيث أمكن
5. تطبيق تقسيم الشبكة لتحديد الحركة الجانبية
قواعد الكشف:
1. مراقبة عمليات Safari/WebKit غير المتوقعة التي تولد عمليات فرعية
2. تنبيه الاتصالات الشبكية غير العادية من عملية Safari
3. تتبع إنشاء الملفات في الدلائل المؤقتة من عمليات المتصفح
4. مراقبة محاولات تنفيذ الأكواد من عمليات عرض WebKit
