Of those 50 attack events, 33 were single vector attacks using CLDAP reflection exclusively,” Arteaga and Majia wrote. A CLDAP DDoS attack is a reflection attack, which is one that uses a legitimate third party to inadvertently send attack traffic or data to the victim. Looking at the attack vectors by week, we see that DDoS attacks remained low most of the spring and summer and then started climbing again early in the third quarter. Our network of UDP honeypots (described previously) confirms that this is the case. When you work in Information Security, working with partial information is part of the job. A distributed reflective denial-of-service (DRDoS) is a form of distributed denial-of-service (DDoS) attack that relies on publicly accessible UDP servers and bandwidth amplification factors (BAFs) to overwhelm a victim’s system with UDP traffic. CLDAP attacks can be up to 70 times more powerful than other DDoS attacks, due to the packet sizes sent back from the server. CLDAP is most commonly encountered on Microsoft Active Directory networks where clients use it to retrieve server information.
