OWASP Automated Threat (OAT) Identity Number
OAT-011

Threat Event Name
Scraping

Summary Defining Characteristics
Collect application content and/or other data for use elsewhere.

Description
Collecting accessible data and/or processed output from the application. Some scraping may use fake or compromised accounts, or the information may be accessible without authentication. The scraper may attempt to read all accessible paths and parameter values for web pages and APIs, collecting the responses and extracting data from them. Scraping may occur in real time, or be more periodic in nature. Some Scraping may be used to gain insight into how it is constructed and operates - perhaps for cryptanalysis, reverse engineering, or session analysis.

When another application is being used as an intermediary between the user(s) and the real application, see OAT-020 Account Aggregation. If the intent is to obtain cash or goods, see OAT-012 Cashing Out instead.
