I have just completed the main levels and I was thinking is there a tool on kali linux or a google dork to find passwords within the source code of a webpage ?
Using python you can get values of any element in page, but this method needs you search some reference, you can search names, ids, data atributes like pass, password, passwd… but this is not so good method because the code can be name="passwrd" or another, if you want some e.g. of this code I can send to you.
