* The documentation uses **WSDL** format and is usually saved in the `?wsdl` path like `https://api.example.com/api/?wsdl`
* An example of this documentation can be found in [http://www.dneonline.com/calculator.asmx](http://www.dneonline.com/calculator.asmx) (WSDL document in [http://www.dneonline.com/calculator.asmx?wsdl](http://www.dneonline.com/calculator.asmx?wsdl)) and you can see an example request calling the `Add` method in [http://www.dneonline.com/calculator.asmx?op=Add](http://www.dneonline.com/calculator.asmx?op=Add)
* For parsing these files and create example requests you and use the tool **SOAPUI** or the **WSDLer** Burp Suite Extension.
* The standard documentation is the WADL file. Find an example here: [https://www.w3.org/Submission/wadl/](https://www.w3.org/Submission/wadl/). However, there are other more developer friendly API representation engines like [https://swagger.io/tools/swagger-ui/](https://swagger.io/tools/swagger-ui/) (check the demo in the page)
* [**VAmPI**](https://github.com/erev0s/VAmPI)**:** VAmPI is a vulnerable API made with Flask and it includes vulnerabilities from the OWASP top 10 vulnerabilities for APIs.
These kind of APIs may be [**vulnerable to XXE**](../../pentesting-web/xxe-xee-xml-external-entity.md), but usually **DTD Declarations** are **disallowed** in the input from the user.
Usually some API endpoints are gong to need more privileges that others. Always try to access the more privileged endpoints from less privileged (unauthorized) accounts to see if it's possible.
Always check the [**CORS**](../../pentesting-web/cors-bypass.md) configuration of the API, as if its allowing to end request with the credentials from the attacker domain, a lot of damage can be done via [**CSRF**](../../pentesting-web/csrf-cross-site-request-forgery.md) from authenticated victims.
If you find _/api/albums/**\<album\_id>**/photos/**\<photo\_id>**_\*\* \*\* you could try also things like _/api/**posts**/\<post\_id>/**comment**/_. Use some fuzzer to discover this new endpoints.
You could **replace** the **`album_id`** parameter with something completely different and potentially get other data: _/api/albums?**account\_id=\<account id>**_
You can try to use the HTTP methods: **GET, POST, PUT, DELETE, PATCH, INVENTED** to try check if the web server gives you unexpected information with them.
In this repository you will find: Mindmaps, tips & tricks, resources and every thing related to API Security and API Penetration Testing. Our mindmaps and resources are based on OWASP TOP 10 API, our expereince in Penetration testing and other resources to deliver the most advanced and accurate API security and penetration testing resource in the WEB!!
The first gate to enter the API Security Empire is to know how to gather information about the API infrastructure and how to perform a powerfull recon on API to extract the hidden doors which made you compromise the whole infrastructure from, so, we provide this updated API Recon mindmap with the latest tools and methodologies in API recon:
Read this document to learn how to **search** and **exploit** Owasp Top 10 API vulnerabilities: [https://github.com/OWASP/API-Security/blob/master/2019/en/dist/owasp-api-security-top-10.pdf](https://github.com/OWASP/API-Security/blob/master/2019/en/dist/owasp-api-security-top-10.pdf)
* [**automatic-api-attack-tool**](https://github.com/imperva/automatic-api-attack-tool): Imperva's customizable API attack tool takes an API specification as an input, generates and runs attacks that are based on it as an output.
* [**Astra**](https://github.com/flipkart-incubator/Astra): Another tool for api testing to find several different web vulnerabilities.
* [**Susanoo**](https://github.com/ant4g0nist/Susanoo): Vulnerability API scanner.
* [**restler-fuzzer**](https://github.com/microsoft/restler-fuzzer): RESTler is the _first stateful REST API fuzzing tool_ for automatically testing cloud services through their REST APIs and finding security and reliability bugs in these services. For a given cloud service with an OpenAPI/Swagger specification, RESTler analyzes its entire specification, and then generates and executes tests that exercise the service through its REST API.
* [**TnT-Fuzzer**](https://github.com/Teebytes/TnT-Fuzzer)**:** TnT-Fuzzer is an OpenAPI (swagger) fuzzer written in python.
* [**APIFuzzer**](https://github.com/KissPeter/APIFuzzer)**:** APIFuzzer reads your API description and step by step fuzzes the fields to validate if you application can cope with the fuzzed parameters.
* [**API-fuzzer**](https://github.com/Fuzzapi/API-fuzzer): API\_Fuzzer gem accepts a API request as input and returns vulnerabilities possible in the API.
* [**race-the-web**](https://github.com/TheHackerDev/race-the-web): Tests for race conditions in web applications by sending out a user-specified number of requests to a target URL (or URLs) _simultaneously_, and then compares the responses from the server for uniqueness.
