A Cash Overflow attack is a Denial of Service attack specifically aimed at exceeding the hosting costs for a cloud application, either essentially bankrupting the service owner or exceeding the application cost limits, leading the cloud service provider to disable the application.

Risk Factors

Given enough resources, fairly easy to launch attack. Quickly detected due to immediate downtime/resources consumption/logging. Impact usually limited to loss of availability.
