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.
A DDoS attack works by several machines repeatedly flooding servers of a website with excessive requests in a short span of time, such that the servers run out of their allotted bandwidth, and become unresponsive. More recently, Russian hacktivist group "Killnet" has launched DDoS attacks on Romanian government sites.

The Romanian national cyber security and incident response team, DNSC, has issued a statement about a series of distributed denial-of-service attacks targeting several public websites managed by the state entities. DNSC is now collaborating with other authorities in the country to map these attacks and mitigate their effect.
Ukraine's computer emergency response team has published an announcement warning of ongoing DDoS attacks targeting pro-Ukraine sites and the government web portal. The threat actors, who at this time remain unknown, are compromising WordPress sites and injecting malicious JavaScript code to perform the attacks.
At 15.3 million requests-per-second, the DDoS bombardment was one of the largest that the internet infrastructure company has seen, and the largest HTTPS attack on record. Other countries generating the most traffic included Russia, Brazil, India, Colombia and the US. Cloudflare researchers didn't name the botnet but said it was one that they've been watching and had seen attacks as large as 10 million rps that matched the same fingerprint.
Cloudflare on Wednesday disclosed that it acted to mitigate a 15.3 million request-per-second distributed denial-of-service attack. "HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection," Cloudflare's Omer Yoachimik and Julien Desgats said.
