## Usage Instructions

1. In Burp Suite, send an API request you want to fuzz to Intruder.
2. Remove the existing API function call, and replace it with two § characters for each text file you want to use.
3. On the "Positions" tab, set Attack type to "Cluster Bomb".
4. On the "Payloads" tab, select 1 for the first Payload set drop-down, then select a Payload type of "Runtime file" and navigate to the directory you downloaded these text files to. Select "actions.txt".
5. Repeat step 4 by setting Payload set 2 to "objects.txt".
6. (Optional step - add more payload sets and set them to "objects.txt" to test for multi-part objects like "UserAccount")
7. Start the attack!
