From PC Mag: Internet infrastructure provider Cloudflare says it fended off a record-breaking DDoS attack that reached a whopping 3.8Tbps.
The attack exceeds the 3.47Tbps DDoS that Microsoft encountered in November 2021, the previous record holder. In both cases, the hackers launched a “volumetric” distributed denial-of-service attack, which is designed to consume all the available internet bandwidth of a website or app, exhausting the capacity and forcing it offline.
In Cloudflare’s case, the 3.8Tbps assault was part of a month-long hacking campaign that began early last month, and has so far spanned over 100 especially large volumetric DDoS attacks, with many surpassing 3Tbps. Cloudflare says it was able to mitigate the record-breaking DDoS attack partly because the company has individual servers across the globe, which can effectively dilute the incoming traffic from a botnet. The company also has systems that can analyze traffic in real time and filter out the malicious data flow.
Without revealing names, Cloudflare said the DDoS campaign has been targeting “multiple customers in the financial services, Internet, and telecommunication industries, among others.” But despite the severity of the assault, Cloudflare was able to essentially shrug off the attacks, citing its robust network coverage and defense systems.
