RFD Checker and Security Assessment Mindset

I recently published two repos on my Github account. One is RFD Checker, which I did with my colleague Paulo Silva, where it scans for Reflected File Download vulnerabilities and the other one is a security mindmap (you can also have other formats). This last one had pretty good success just because it a mindset for helping infosec peers and bug bounty hunters on their assessments.

Feel free to share it and participate on any of the projects. They are open-source and with the help of the infosec community they can become a better tool to your arsenal.

Free online tools to help your #bugbounty

Free online tools to help your #bugbounty

I’m getting a few emails asking some tips on how to get some bounties. Because I like to help others and I’m a share knowledge believer 🙂 I wrote this small article about using the right online tools and earn some bucks on bounty programs.

Most experience bug hunters already know most of this tools but this is mostly for starters.

SSL validation
URL: https://www.ssllabs.com/ssltest/

Qualys provides a free online tool that runs a complete test on a target SSL. Heartbleed, OpenSSL CCS vuln, BEAST, POODLE, etc all of these are covered in this online test.

Missing SPF? Let’s test it…
URL: http://www.kitterman.com/spf/validate.html

These tools are meant to help you check SPF records on your target. For many bug bounties participants this is one of the first things to try. Usually get’s the minimum payout if in-scope. On HackerOne, Shopify already paid $500 on this missing email security header – https://hackerone.com/reports/54779

Test X-FRAME-Options
URL: http://savanttools.com/test-frame

This tool is useful for detecting sites that use the X-FRAME-OPTIONS header to block framing, or use frame-breaking / frame-busting Javascript. Clickjacking attacks can be achieved with the help of this tool.

Find subdomains of a domain
URL: https://pentest-tools.com/information-gathering/find-subdomains-of-domain

pentest-tools.com offers 40 credits every day to a user for free and using this information gathering information on the subdomains will take you 20 credits so you can use it twice a day. This is very usefull to find other domain targets.

Online fuzzer
URL: https://pentest-tools.com/website-vulnerability-scanning/discover-hidden-directories-and-files

With only 10 credits [you have 40 credits every day] this online URL Fuzzer can be used to find hidden files and directories on a web server.
This is a discovery activity which allows you to discover resources that were not meant to be publicly accessible (ex. /backups, /index.php.old, /archive.tgz, /source_code.zip, etc).
With a file/direcotry fuzzer you can always find interesting stuff. I already found a couple of phpinfo.php files on major companies and got few bounties with them.

Using Drupal?
URL: https://hackertarget.com/drupal-security-scan/

With this online you get a overview of the Drupal version used, template name, if directory indexing is enabled, etc. Some of this information you could use to run further tests and determine if you can get someting vulnerable from the Drupal instalation.

Using WordPress?
URL: https://hackertarget.com/wordpress-security-scan/

I’m a big fan of wp-scan but if you need a free online tool HackerTarget will do a good job for you.
This tool will check the version of WordPress, check directory indexing, list plugins [and if new updates are available], user enumeration, etc. With this information you can check for vulnerable plugins and provide a good report about that.

Using Joomla?
URL: https://hackertarget.com/joomla-security-scan/

Like the previous tools this one also checks for Joomla instalattions information. Take a look into the plugins/components. Usually there are something to look for. Compare versions and Google for changelogs about vulnerabilities. Very often in the changelog the vulnerability is not public but if it says CSRF on options-windows.php. Just try to download that version and audit it yourself. I’ll do that 🙂

Target store using Magento?
URL: https://www.magereport.com/

Scan your targets Magento shop for known security vulnerabilities. This is a very useful tool that can get a few vulnerabilities in your bounty quest.

I would like to add that there are better tools that could be installed on your operating system but that could be on another article 🙂

Tip 1: Always read carefully the bounty program details to check what’s in-scope. Always respect the rules.
Tip 2: Don’t forget also to read my article. Don’t copy paste your online results on the report and voila!
