Record-Breaking DDoS Cyberattack

Cloudflare Mitigates Largest DDoS Attack on Record

Cloudflare has mitigated the biggest distributed denial of service (DDoS) attack on record, according to a new report. The DDoS attack, which hit an East Asia-based telecoms firm last year, reached 5.6 terabits per second (Tbps) and lasted for 80 seconds. It was comprised of a botnet of 13,000 devices taken over by the Mirai malware, according to Cloudflare’s blog.

DDoS Attacks — Growing In Number And Getting Faster

DDoS attacks are increasingly common. Last year, Microsoft confirmed that an Azure outage on July 30 lasting nearly 10 hours was triggered by a distributed denial of service cyberattack. Overall, Cloudflare blocked around 21.3 million DDoS attacks in 2024, a 53% increase on 2023. The number of DDoS attacks exceeding 1 Tbps grew 1,885% in Q4 from Q3.

Ransom DDoS Is On The Rise

In the final quarter of 2024, Cloudflare observed a surge in Ransom DDoS attacks, where adversaries try to extort money by threatening to take down their targets’ web properties or networks. China maintained its position as the most attacked country.

Conclusion

As DDoS attacks surge, causing outages and worse, it’s important to get the cybersecurity basics right. Understand your service, the risks associated with losing access to it, and ensure you are as resilient as possible to avoid being hit in the first place.
