OWASP Automated Threat (OAT) Identity Number
Threat Event Name
Summary Defining Characteristics
Obtain limited-availability and/or preferred goods/services by unfair methods.
Acquisition of goods or services using the application in a manner that a normal user would be unable to undertake manually.
Although Scalping may include monitoring awaiting availability of the goods or services, and then rapid action to beat normal users to obtain these, Scalping is not a "last minute" action like OAT-013 Sniping, nor just related to automation on behalf of the user such as in OAT-006 Expediting. This is because Scalping includes the additional concept of limited availability of sought-after goods or services, and is most well known in the ticketing business where the tickets acquired are then resold later at a profit by the scalpers/touts. This can also lead to a type of user denial of service, since the goods or services become unavailable rapidly.
