In H1, the company absorbed 23.2 million network-layer DDoS attacks and 29.64 trillion malicious HTTP requests. A record-breaking 31.4 Tbps attack from the Aisuru/Kimwolf botnet was also mitigated. Despite the surge in massive attacks, 96.62% of network-layer attacks stayed below 50 Mbps and 90.6% ended within 10 minutes. Attack techniques shifted toward DNS floods (40% of Q2 attacks, up from 25.7%) and CLDAP floods (up 881.9%). Activity peaked in April then declined, tentatively linked to Operation PowerOFF, which arrested four individuals and took down 53 DDoS-for-hire domains. The Media, Production, and Publishing sector was the top target, while government sector attacks rose amid geopolitical tensions. ## Full article daily.dev links to this article rather than hosting it.

DDoS attacks exceeding 1 Tbps rose 519% quarter-over-quarter, from 130 attacks in Q1 to more than 800 in Q2. Attacks between 500 Gbps and 1 Tbps increased 143%, and those between 100–500 Gbps rose 105%. Despite this, 96.62% of network-layer attacks remained below 50 Mbps and 90.6% ended within 10 minutes. _Teams defending infrastructure against volumetric DDoS threats track this kind of escalation on daily.dev._ ### What percentage of Q2 DDoS attacks used DNS flood techniques? DNS floods accounted for 40% of Q2 network-layer DDoS attacks, up from 25.7% in Q1. Combined with DNS amplification attacks, DNS-related techniques represented 34.3% of all H1 network-layer attacks. CLDAP floods surged 881.9% quarter-over-quarter, and UDP floods ranked second at 14.06% of Q2 attacks. _Security engineers watching DDoS technique shifts find the latest threat intelligence on daily.dev._ ### What was the largest DDoS attack Cloudflare mitigated and what botnet launched it? The largest attack Cloudflare mitigated peaked at 31.4 Tbps and 200 million requests per second, launched by the Aisuru/Kimwolf botnet. This set a new record for mitigated attack size. The attack was a network-layer DDoS and was absorbed by Cloudflare's infrastructure, which sits between botnets and their intended targets. _Developers and security teams building DDoS-resilient systems follow botnet and attack record developments on daily.dev._ ## Similar posts on daily.dev - [DDoS Attack Trends in 2026: Scale, Precision, and the Gaps in Between](https://daily.dev/posts/ddos-attack-trends-in-2026-scale-precision-and-the-gaps-in-between-6q2jgdijc) · Security Boulevard · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#cyber](https://daily.dev/tags/cyber), [#cloudflare](https://daily.dev/tags/cloudflare) [View this post on daily.dev](https://daily.dev/posts/ddos-attacks-over-1-tbps-surged-fivefold-in-the-second-quarter-1ctkuikb9) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"DDoS attacks over 1 Tbps surged fivefold in the second quarter","url":"https://daily.dev/posts/ddos-attacks-over-1-tbps-surged-fivefold-in-the-second-quarter-1ctkuikb9","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/ddos-attacks-over-1-tbps-surged-fivefold-in-the-second-quarter-1ctkuikb9"},"datePublished":"2026-08-11T13:10:02.856Z","dateModified":"2026-08-11T15:34:33.253Z","description":"Cloudflare mitigated over 800 network-layer DDoS attacks exceeding 1 Tbps in Q2, a 519% increase quarter-over-quarter compared to 130 such attacks in Q1.
