roboXtractor

This tool has been developed to extract endpoints marked as disallow in robots.txt file. It crawls the file directly on the web and has a wayback machine query mode (1 query for each of the previous 5 years).

Possible uses of roboXtractor:

• Generate a customized wordlist of endpoints for later use in a fuzzing tool (-m 1).
• Generate a list of URLs to visit (-m 0).

🛠️ Installation

If you want to make modifications locally and compile it, follow the instructions below:

> git clone https://github.com/Josue87/roboxtractor.git
> cd roboxtractor
> go build

If you are only interested in using the program:

> go get -u github.com/Josue87/roboxtractor

Note If you are using version 1.16 or higher and you have any errors, run the following command:

You can ignore the -u flag and pass a file directly as follows:

Only the results are written to the standard output. The banner and information messages with the -v flag are redirected to the error output,

👾 Usage

The following are some examples of use:

roboxtractor --help
cat urls.txt | roboxtractor -m 0 -v
roboxtractor -u https://www.example.com -m 1 -wb
cat urls.txt | roboxtractor -m 1 -s > ./customwordlist.txt
cat urls.txt | roboxtractor -s -v | uniq > ./uniquewordlist.txt
echo http://example.com | roboxtractor -v
echo http://example.com | roboxtractor -v -wb

Checking Wayback Machine:

Github had many entries in the file, which were not useful, a cleaning process is done to avoid duplicates or entries with *. Check the following image:

For example:

• /gist/*/*/* is transformed as gist.
• /*/tarball is trasformed as tarball.
• /, /* or similar entries are removed.
