Record-Breaking 7.3 Tbps DDoS Attack: A Wake-Up Call for Internet Security

Cloudflare reported a record-breaking 7.3 Tbps distributed denial-of-service (DDoS) attack, unleashing 37.4 TB of junk traffic in just 45 seconds. Attackers 'carpet bombed' nearly 22,000 destination ports of a single IP address, exploiting the UDP protocol's lack of connection verification to overwhelm the target server. This incident highlights the escalating threat to internet security and the growing scale and sophistication of large-scale DDoS attacks.
