هو شكل من أشكال هجوم حجب الخدمة الموزع (DDOS) الذي يقوم بإخراج الحاسوب أو الشبكة عن الخدمة، وذلك من خلال استغلال نقاط الضعف في بروتوكول الإنترنت (IP) وبروتوكول التحكم في الإنترنت (ICMP).
سُمي الهجوم بهذا الاسم نسبةً للشخصيات الكرتونية "السنافر" بسبب قدرتها على هزيمة الأعداء من خلال التعاون والعمل معاً فيما يشبه طريقة عمل هجوم السنافر.
كان هجوم السنافر في البداية شيفرة برمجية ضارة كتبها المتسلل دان موشوك، إذ وقعت إحدى الهجمات الأولى التي استخدمت هذا النهج عام 1998 واستهدفت في البداية جامعة مينيسوتا، ما أدى إلى إغلاق أجهزة الحاسوب في جميع أنحاء الولاية، وإبطاء الشبكات، والمساهمة في فقدان البيانات.
يعمل هجوم السنافر من خلال هذه العملية المكونة من ثلاث خطوات:
يمكنك من خلال هذه الممارسات تقليل احتمال الوقوع ضحية لهجوم السنافر:
