Anatomy of a DDoS amplification attack
Amplification attacks are one of the most common distributed denial of service DDoS attack vectors. These attacks are typically categorized as flooding or volumetric attacks, where the attacker succeeds in generating more traffic than the target can process, resulting in exhausting its resources...
Microsoft Fended Off a Record 2.4 Tbps DDoS Attack Targeting Azure Customers
Microsoft on Monday revealed that its Azure cloud platform mitigated a 2.4 Tbps distributed denial-of-service DDoS attack in the last week of August targeting an unnamed customer in Europe, surpassing a 2.3 Tbps attack stopped by Amazon Web Services in February 2020. "This is 140 percent higher...
