The first phase in security assessment is focused on collecting as much information as possible about a target application. One tool to do that is Goofile, it allows to search a specify filetype in a specify domain using Google…
I read that the development of this python script was stopped in the 2012 so yesterday I wrote my own Golang version called Go-ofile just for fun, it is a Golang clone of goofile which allows to have a binary file to take anywhere without deps.
The usage is very simple, you have only 2 flags:
./go-ofile -d unipa.it -f pdf
Obviously for suggestions, bugs, etc. you can open an issue; PR are welcome too!
