This screen allows you to configure the fuzzing options:
The category that will be initially selected shown when the Fuzz dialog is displayed.
The number of threads the scanner will use per host.
Increasing the number of threads will speed up the scan but may put extra strain on the computer ZAP is running on and the target host.
Allows you to add your own files to be used when fuzzing.
These should be text files with one attack per line.
Files are added to the ‘fuzzers’ directory underneath the ZAP home directory.
