OAT
Abbreviation for OWASP Automated Threat
In short and in plain language
OAT is a short label for attacks that programs run on their own against websites.
For example, a program fills lots of forms with adverts.
Each type of attack has a name and a number.
This helps you make sense of odd things on your own website.
Definition
OAT is the abbreviation the OWASP project uses to label automated attacks on web applications. Each threat type has a name and a number in its classification, for example OAT-017 for injecting advertising or questionable content into forms and messages on a large scale. This helps to classify unusual activity on your own website.
