  Cloud computing relies on sharing computing resources rather than having
local servers or personal devices to handle applications. Nowadays, cloud
computing has become one of the fastest growing fields in information
technology. However, several new security issues of cloud computing have
emerged due to its service delivery models. In this paper, we discuss the case
of distributed denial-of-service (DDoS) attack using Cloud resources. First, we
show how such attack using a cloud platform could not be detected by previous
techniques. Then we present a tricky solution based on the cloud as well.
