Schneier - 15.3 Million Request-Per-Second DDoS Attack

Cloudflare is reporting a large DDoS attack against an unnamed company “operating a crypto launchpad.”

While this isn’t the largest application-layer attack we’ve seen, it is the largest we’ve seen over HTTPS. HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection. Therefore it costs the attacker more to launch the attack, and for the victim to mitigate it. We’ve seen very large attacks in the past over (unencrypted) HTTP, but this attack stands out because of the resources it required at its scale.

The attack only lasted 15 seconds. No word on motive. Was this a test? Or was that 15-second delay critical for some other fraud?

News article.
