Unprecedented 7.3 Tbps DDoS Attack Recorded in June 2025

An unprecedented DDoS attack of 7.3 Tbps was recorded in June 2025. The majority of the attack was carried out via UDP (User Datagram Protocol) packets, which are used for time-sensitive communications such as video streaming, gaming applications, and DNS queries. Unlike TCP, UDP does not require establishing a formal connection before transferring data, allowing attackers to overwhelm a target server without prior authorization. UDP flood attacks send a large number of datagrams to multiple ports of the target system, forcing it to respond with an equal number of data packets, ultimately overwhelming the system and denying legitimate traffic.
