Customization

If you want to edit or add new bypasses, you can add it directly to the specific file in payloads folder and the tool will use it.

Basic usage:

./dontgo403 -u https://domain.com/admin

Verbose mode + proxy enabled:

./dontgo403 -u https://domain.com/admin -p http://127.0.0.1:8080 -v

Parse request from Burp:

./dontgo403 -r request.txt

Use custom header + specific IP address for bypasses:

./dontgo403 -u https://domain.com/admin -H "Environment: Staging" -b 8.8.8.8

Set new max of goroutines + add delay between requests:

./dontgo403 -u https://domain.com/admin -m 10 -d 200
