There had been “thousands” of hyper-volumetric HTTP distributed denial of service (DDoS) attacks in the time since the HTTP/2 Rapid Reset vulnerability was disclosed, a new report from Cloudflare has claimed, adding that 89 of those exceeded 100 million requests per second (rps). Thanks to these attacks, the total amount of HTTP DDoS attacks for the third quarter of the year, compared to Q2, was up 65%, the company added. "Similarly, L3/4 DDoS attacks also increased by 14%,” it added... View the full article -
A vulnerability in the HTTP/2 network protocol is currently being exploited, resulting in the largest DDoS attack in history. Find out what security teams should do now, and hear what Cloudflare's CEO has to say about this DDoS.View the full article -
A number of Google services and Cloud customers have been targeted with a novel HTTP/2-based DDoS attack which peaked in August. These attacks were significantly larger than any previously-reported Layer 7 attacks, with the largest attack surpassing 398 million requests per second. The attacks were largely stopped at the edge of our network by Google's global load balancing infrastructure and did not lead to any outages. While the impact was minimal, Google's DDoS Response Team reviewed the attacks and added additional protections to further mitigate similar attacks. In addition to Google's internal response, we helped lead a coordinated disclosure process with industry partners to address the new HTTP/2 vector across the ecosystem... View the full article -
Over the last few years, Google's DDoS Response Team has observed the trend that distributed denial-of-service (DDoS) attacks are increasing exponentially in size. Last year, we blocked the largest DDoS attack recorded at the time. This August, we stopped an even larger DDoS attack — 7½ times larger — that also used new techniques to try to disrupt websites and Internet services. This new series of DDoS attacks reached a peak of 398 million requests per second (rps), and relied on a novel HTTP/2 “Rapid Reset” technique based on stream multiplexing that has affected multiple Internet infrastructure companies. By contrast, last year’s largest-recorded DDoS attack peaked at 46 million rps. For a sense of scale, this two minute attack generated more requests than the total number of article views reported by Wikipedia during the entire month of September 2023... View the full article
