More Sophisticated DDoS Attack a New Threat to Apache Servers

A once flawed DDoS attack targeting the world’s most widely used Web servers has improved its cryptography and attack capabilities to become a more serious threat.

MP-DDoser, also known as “IP-Killer,” uses a relatively new low-bandwidth, “asymmetrical” HTTP attack to inflict a denial-of-service attack against Apache Web servers by sending a very long HTTP header. This forces the web servers to do a great deal of server-side work for a relatively small request. Additionally, the malware now incorporates multiple layers of encryption.
