DDoS attacks don't arrive on little cat feet; they announce their presence with the subtlety of a shovel to the face. Two just-released reports show that these loud DDoS attacks are getting louder, larger, and more numerous with the passage of time.
Verisign released its Q1 2018 DDoS Trends Report and Akamai published its State of the Internet/Security Summer 2018 report and neither was filled with good news if your job is defending a company or network against DDoS attacks. Together, the two reports paint a detailed and disturbing picture of the way DDoS attacks are evolving to be both more common and more dangerous.
Both reports noted the largest DDoS attack in the period, a 170 Gbps, 65 Mpps (million packets per second) operation notable for two things: its target and its originator.
