Cloudflare states that it reduced a record-brakeing distributed Daniel of Service (DDOS) attack in May 2025, which reached 7.3 TBPS, targeted a hosting provider.
DDOS definitely attacks flood goals with large -scale traffic with the sole purpose to overwhelm the server and make service recession, disruption or outage.
This new attack, which is 12% larger than the previous record, distributed 37.4 A huge data of TB In just 45 seconds. This is equal to about 7,500 hours HD streaming or 12,500,000 JPEG photos.

A web infrastructure and cyber security giant, Claudflare, provides a network-layer security service called ‘Magic Transit’, a web infrastructure specialized in DDOS mitigation, used by the target customer.
The attack came from IP address, 122,145 sources spread over 161 countries, with majority located in Brazil, Vietnam, Taiwan, China, Indonesia and Ukraine.
The “waste” data package was distributed at several destination ports on the package afflicted system, average of 21,925 ports per second and at 34,517 ports/seconds.
This strategy of scattering traffic helps overwhelm the systems that detect firewalls or intrusion, but Claudflair claims that eventually is able to reduce the attack without human intervention.

The Anycast Network of Cloudflare spread the traffic traffic in 477 data centers in 293 locations, taking advantage of major technologies such as real-time fingerprinting and intra-detaa center gossip, which is gauge for real-time intelligence sharing and automated rules compilation.
Although almost the entire attack came from UDP flood, accounting for 99.996% of total traffic, including many other vectors, including:
- Qotd image
- Echo reflection
- NTP amplification
- Mirai Botet UDP Flood
- Portmap flood
- Ripv1 amplification
Each vector exploited heritage or poorly configured services. Although it was only a small percentage of the attack, it served as part of the theft and effective strategy of the attackers and could also help in investigation for weaknesses and misunderstandings.
Cloudflare says that valuable IOCs were involved in time from this attack DDOS Botet Danger FeedA free service that helps organizations block malicious IP addresses.
More than 600 organizations have taken membership of this feed, and the internet giant company calls any other at risk of DDOS attacks and blocks the attacks before reaching its infrastructure.
Patching meant complex scripts, long and endless fire drills. No more.
In this new guide, the tines break down how it is leveling with modern organ automation. Patch fast, reduce overhead, and focus on strategic tasks – no complex script is required.
