🔧 Remediation Steps (English)
IMMEDIATE ACTIONS:
1. Identify all Chromium-based browsers in use (Chrome, Edge, Opera, Brave) across your organization
2. Enable automatic browser updates or manually update to patched versions immediately
3. Block access to untrusted websites and implement web filtering
4. Disable JavaScript execution in browsers if operationally feasible
PATCHING GUIDANCE:
1. Update Google Chrome to version 93.0.4577.82 or later
2. Update Microsoft Edge to version 93.0.961.52 or later
3. Update Opera to version 77.0 or later
4. Verify patch installation through browser version checks (chrome://version)
COMPENSATING CONTROLS:
1. Implement Content Security Policy (CSP) headers to restrict script execution
2. Deploy web application firewalls (WAF) to detect malicious payloads
3. Use browser isolation technology for high-risk users
4. Monitor for suspicious process creation and memory access patterns
DETECTION RULES:
1. Monitor for unexpected child processes spawned by browser processes
2. Alert on abnormal memory access patterns in V8 engine processes
3. Track browser crashes and segmentation faults
4. Monitor for exploitation attempts via IDS/IPS signatures for CVE-2021-37975
🔧 خطوات المعالجة (العربية)
الإجراءات الفورية:
1. تحديد جميع متصفحات Chromium المستخدمة (Chrome و Edge و Opera و Brave) في المؤسسة
2. تفعيل التحديثات التلقائية للمتصفح أو التحديث اليدوي للإصدارات المصححة فوراً
3. حظر الوصول إلى المواقع غير الموثوقة وتطبيق تصفية الويب
4. تعطيل تنفيذ JavaScript في المتصفحات إن أمكن
إرشادات التصحيح:
1. تحديث Google Chrome إلى الإصدار 93.0.4577.82 أو أحدث
2. تحديث Microsoft Edge إلى الإصدار 93.0.961.52 أو أحدث
3. تحديث Opera إلى الإصدار 77.0 أو أحدث
4. التحقق من تثبيت التصحيح من خلال فحوصات إصدار المتصفح
الضوابط البديلة:
1. تطبيق سياسة أمان المحتوى (CSP) لتقييد تنفيذ البرامج النصية
2. نشر جدران حماية تطبيقات الويب (WAF) للكشف عن الحمولات الضارة
3. استخدام تقنية عزل المتصفح للمستخدمين عالي الخطورة
4. مراقبة أنماط الوصول إلى الذاكرة المريبة
قواعد الكشف:
1. مراقبة العمليات الفرعية غير المتوقعة التي يتم إنشاؤها بواسطة عمليات المتصفح
2. تنبيهات على أنماط الوصول إلى الذاكرة غير الطبيعية في عمليات محرك V8
3. تتبع أعطال المتصفح والأخطاء في الوصول إلى الذاكرة
4. مراقبة محاولات الاستغلال عبر توقيعات IDS/IPS
