FourOhMe is a tool for testing HTTP headers on a website in order to try to bypass 40* HTTP codes. It tries to bypass the 40* status code by manipulating the HTTP request via HTTP headers and URL payloads.

Install Golang, then run:

go install -v github.com/topscoder/fourohme@latest

FourOhMe can be used in three ways:

1. Reading URLs from a file:

   $ fourohme -file urls.txt
   

   where urls.txt is a file containing a list of URLs separated by newlines.

2. Reading URLs from standard input (STDIN):

   $ cat urls.txt | fourohme
   

   where urls.txt is a file containing a list of URLs separated by newlines.

   Or attach in your favourite chain commands:

   $ cat domains.txt | subfinder | httpx -mc 401,402,403,404,405 -silent | fourohme 
   

3. Reading single URL:

   $ fourohme -url https://foo.bar
   

• -file: Path to a file containing URLs.
• -force: Force the scanner to scan all URL's regardless of the initial HTTP status code.
• -silent: Don't print shizzle. Only what matters.
• -threads: The amount of threads to be used to execute the HTTP requests. Be gentle or get blocked. (default 4)
• -url: URL to make requests to

FourOhMe prints the responses of each request in a colored format. A successful response (HTTP status code 200) is printed in green, while an unsuccessful response is printed in red.

Contributions are welcome! If you find a bug or want to suggest a new feature, please open an issue or submit a pull request.

• Add a WAF check
• Add content check filter false positives ("The requested URL was rejected")
• Try to filter false positives by checking the content-length
