#bugbountytips for testing Business Logic errors, a thread:

1. You need to have a good understanding of how the application is supposed to function. This requires reviewing the app's docs, reading about the business model, and testing the app to see how it behaves normally.
2. Identify critical business processes: Once you have a good understanding of the logic, identify the critical processes that the application performs. These are the processes that are essential to the application's functionality and are likely to be the target of attacks.
3. Test for edge cases: Business logic errors often occur when the application encounters unexpected or edge cases. Test the application to see how it behaves when inputs are outside the expected range or when multiple processes are occurring simultaneously.
4. Attempt to bypass controls: Many business logic errors occur when an attacker is able to bypass controls that are supposed to prevent unauthorized access or actions. Try to identify any controls that are in place and attempt to bypass them.
5. Test the application thoroughly: Business logic errors can be difficult to find, so it's important to thoroughly test the application. Use a variety of techniques, such as manual testing, automated testing, and fuzzing, to ensure that you've identified as many potential issues
Remember that business logic errors can have serious consequences, so it's important to approach testing with a critical eye and to report any potential issues to the organization as soon as possible.

1/n
Always begin with a thorough understanding of the application you're testing. Identify all possible user roles and their access rights. This knowledge is crucial for accurately identifying IDOR vulnerabilities. 🧠📝
Pay attention to API endpoints that handle user-specific data. Keep an eye out for patterns in URL parameters or request payloads. Examine how the application validates user input and authorization checks for these sensitive resources. 📡🔬
