What Are the Differences Between DDoS Attacks and Challenge Collapsar Attacks?

Challenge Collapsar (CC) attack is a type of Distributed Denial of Service (DDoS) attack.

DDoS Attack

DDoS attacks are distributed and coordinated large-scale DoS attacks. Multiple attackers in different locations launch attacks to one or more targets at the same time, or an attacker controls multiple compromised computers in different locations and uses these computers to attack the victim at the same time. The DDoS attack process consists of target confirmation, botnet establishment, attack launching.

CC Attack

A Challenge Collapsar (CC) attack is an attack that standard HTTP requests are sent to a targeted web server frequently. The attacker controls some servers to keep sending a large number of data packets to the target server, causing resource exhaustion and breakdown of the server.
