QUICK TIPS

Quick Tips Don’t use scanner.

Use Google Dorks. I. EX: inurl: src|path|link|url II. filetype:asp|aspx|jsp|jspa|php

Make your own.

Create Google alerts for recent changes in Bug bounty programmes or for any other security related blogs.

Look out for information disclosure which are quick to find:I. https://www.site.com/.htaccess if you are lucky then you will get

access of .htaccess. Now go and report this bug and earn some $$ . II. Go to https://www.site.com/server-statusIII. GO to https://www.site.com/.svn/entries

. Try for Directory traversal using python script and using it try to find RCE .

IDOR by changing id parameters in request .

Unauthorized access of Data. Ex: Try to access pics or conversations or files which is deleted using api.

Try to Complete CTF, online hacking Challenges.

Attend Webinars, Security Conferences.

Make Good relations with other security researchers and try to learn something from them.

Try to report Exploitable bugs .Don’t waste your and other’s time by reporting Non-Exploitable issues.

Try to test each platform IOS, ANDROID, SOFTWARE , Web Applications.

Read as much as you can.

I was like
