Record-Breaking DDoS Attack Targets Cloudflare Customer
Updated June 22, 2025
A Cloudflare customer was recently targeted by a massive distributed denial-of-service (DDoS) attack, clocking in at a record-breaking 7.3 terabits per second. this large-scale attack,designed to overwhelm Internet services,demonstrates the increasing intensity of online threats.
The attack unleashed 37.4 terabytes of junk traffic on the target in just 45 seconds. To put that into perspective, itS equivalent to streaming 7,500 hours of HD video or downloading more than 9,300 full-length HD movies in under a minute.
Cloudflare reported that the attackers used a “carpet bombing” technique, targeting nearly 22,000 destination ports on a single IP address. In total, 34,500 ports were hit, indicating a well-planned adn comprehensive attack strategy. The vast majority of the malicious traffic was sent using User Datagram Protocol (UDP) packets.
UDP is often used for time-sensitive communications like video playback and DNS lookups because it doesn’t establish a formal connection before sending data. However, this lack of a handshake also makes it vulnerable to UDP flood attacks.These attacks flood the target server with massive volumes of packets, overwhelming its resources and preventing legitimate traffic from getting thru. The DDoS attack role is to disrupt services.
what’s next
As DDoS attacks continue to evolve in scale and sophistication, organizations must prioritize robust cybersecurity measures and DDoS mitigation strategies to protect their online infrastructure and ensure uninterrupted service for their users.The role of security providers will continue to grow.
