DDoS threat report for 2023 Q1

Welcome to the first DDoS threat report of 2023. DDoS attacks, or distributed denial-of-service attacks, are a type of cyber attack that aim to overwhelm Internet services such as websites with more traffic than they can handle, in order to disrupt them and make them unavailable to legitimate users. In this report, we cover the latest insights and trends about the DDoS attack landscape as we observed across our global network.

Killnet and AnonymousSudan DDoS attack Australian university websites, and threaten more attacks - here's what to do about it

Over the past 24 hours, Cloudflare has observed HTTP DDoS attacks targeting university websites in Australia. Universities were the first of several groups publicly targeted by the pro-Russian hacker group Killnet and their affiliate AnonymousSudan, as revealed in a recent Telegram post. The threat actors called for additional attacks against 8 universities, 10 airports, and 8 hospital websites in Australia beginning on Tuesday, March 28.

Cloudflare Cache Reserve Walkthrough and Demo

Many organizations store large, infrequently changing assets like videos, images or large binary files on cloud provider networks for easy access. Unfortunately, any time an asset is fetched from the origin server, many cloud providers charge an egress fee. These egress fees can quickly add up and become a significant cost. Cloudflare’s Cache Reserve helps minimize these unnecessary egress fees by reducing origin egress and optimizing cache hit ratios.

Everything you might have missed during Security Week 2023

Security Week 2023 is officially in the books. In our welcome post last Saturday, I talked about Cloudflare’s years-long evolution from protecting websites, to protecting applications, to protecting people. Our goal this week was to help our customers solve a broader range of problems, reduce external points of vulnerability, and make their jobs easier. We announced 34 new tools and integrations that will do just that.

Account Security Analytics and Events: better visibility over all domains

Cloudflare offers many security features like WAF, Bot management, DDoS, Zero Trust, and more! This suite of products are offered in the form of rules to give basic protection against common vulnerability attacks. These rules are usually configured and monitored per domain, which is very simple when we talk about one, two, maybe three domains (or what we call in Cloudflare’s terms, “zones”).
