Cloudflare said it this month staved off another record-breaking HTTPS-based distributed denial-of-service attack, this one significantly larger than the previous largest DDoS attack that occurred only two months ago.

In April, the biz said it mitigated an HTTPS DDoS attack that reached a peak of 15.3 million requests-per-second.

Like the attack in April, the most recent one not only was unusual because of its size, but also because it involved using junk HTTPS requests to overwhelm a website, preventing it from servicing legit visitors and thus effectively falling off the 'net.

"HTTPS DDoS attacks are more expensive in terms of required computational resources because of the higher cost of establishing a secure TLS encrypted connection," he wrote.

In its own report in April, Cloudflare officials said there was a huge spike in application-layer DDoS attacks in the first quarter and a smaller jump in the number of network-layer attacks.

Microsoft over the past year twice reported that it mitigated the largest recorded DDoS attacks in history, with the most recent one occurring in November 2021 that hit 3.47 terabits-per-second and targeted a customer on Azure.
