Based on Learning about Vulnerabilities

“Being a hacker is lots of fun, but it’s a kind of fun that takes lots of effort. The effort takes motivation.”

Now let’s start with the basic learning about InfoSec the first and really most important step would be to choose a proper initial path that you are going to start learning. Choosing the right path to start in Bug Bounty is very important. It totally depends upon your interest, like some people choose Web Application path first coz it’s easy to learn and go through than mobile and others… (Some of the resources are moved here from my old blog that’s I’m going to remove but these are updated and properly arranged by my experience) I’ll focus on Web, & Mobile Here coz this is what my interest is.

Before I add anything else I’ll suggest You to actually go through Hacker101 By HackerOne https://www.hacker101.com/ And Bugcrowd University https://www.bugcrowd.com/hackers/bugcrowd-university/ Both of these contain a Huge list of resources and lectures that can help you in even a better way than many of us can’t but as you guys are following this as well so I decided to add them here also.

Web App Security:

Before I Suggest you what to Learn first if you follow my suggested path l’ll like to tell you some ways you can practice your skills..

CTF(Capture The Flag): Now to practice for Bug Bounties you can participate in CTF challenges. Just like the name suggests “Capture The Flag” there are several challenges for you to solve which deals with real-world vulnerabilities. The more you practice on these challenges the more you will learn about the different technologies required to break into an application or a system.

For Web App, I’ll suggest you guys read the following books & guides first >https://www.packtpub.com/networking-and-servers/mastering-modern-web-penetration-testing >https://www.amazon.com/Hackers-Underground-Handbook-secure-systems/dp/1451550189 >https://leanpub.com/web-hacking-101 >https://www.amazon.com/gp/product/1593275641/ >https://www.amazon.com/gp/product/1512214566/ >https://www.amazon.com/Tangled-Web-Securing-Modern-Applications-ebook/dp/B006FZ3UNI/

Reading these books you will get good knowledge about Web App Penetration testing & Security testing in general and in-depth. In addition to these books, I’ll suggest you guys should really give good time reading and understanding OWASP Testing Guide & OWASP Top 10 Vulnerabilities from 2010-2017 OWASP Testing project: >https://www.owasp.org/index.php/OWASP_Testing_Project

OWASP Top 10 Project: >https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project#OWASP_Top_10_for_2010 >https://www.owasp.org/index.php/Category:OWASP_Top_Ten_Project#OWASP_Top_10_for_2013 >https://www.owasp.org/images/7/72/OWASP_Top_10-2017_%28en%29.pdf.pdf

Adding a Few basic Pdfs for you guys to go through and save locally to you can keep it revised and keep learning from them. I’ll say they gonna help you almost a hundred percent of the time. So do give these a good time > Kali Linux Revealed https://docs.kali.org/pdf/kali-book-en.pdf > Nmap Cheat Sheet https://s3-us-west-2.amazonaws.com/stationx-public-download/nmap_cheet_sheet_0.6.pdf > Metasploit Cheat Sheet: https://www.sans.org/security-resources/sec560/misc_tools_sheet_v1.pdf

Now by this point, I’ll say You have done Good enough research and given good time to practice and learn that you can jump into a Bug Bounty Program to test in real-life environment outside CTF, or test environments. So you can happily jump to the pages at https://bugcrowd.com/programs https://hackerone.com/directory

PentesterLab There’s only one way to properly learn web penetration testing: by getting your hands dirty. PentesterLab teaches how to manually find and exploit vulnerabilities and is a good resource to learn and practice all at once.

Pentester Academy

Another Great resource to practice using online labs and learn, they also provide certifications.

And Select a Program But I’ll suggest you read till the end.

Following all of them books, testing guides you might have an idea of vulnerabilities so i’ll name a few common ones and try to give good reference to learn them easily.

Cross-Site Request Forgery (CSRF)

Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they’re currently authenticated. References to read: >https://www.imperva.com/learn/application-security/csrf-cross-site-request-forgery/?utm_campaign=Incapsula-moved >https://www.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF) >https://www.netsparker.com/blog/web-security/csrf-cross-site-request-forgery/ Some POCs:

Cross-Site Scripting (XSS)

XSS enables attackers to inject client-side scripts into web pages viewed by other users.

References to read: >https://www.owasp.org/index.php/Cross-site_Scripting_(XSS) >https://portswigger.net/web-security/cross-site-scripting >https://excess-xss.com/ Some POCs:

SQL Injection

SQL injection, is a common attack vector that uses malicious SQL code for backend database manipulation to access information that was not intended to be displayed.

References to read: >https://www.owasp.org/index.php/SQL_Injection >https://portswigger.net/web-security/sql-injection >https://www.imperva.com/learn/application-security/sql-injection-sqli/ >https://www.w3schools.com/sql/sql_injection.asp

Some POCs:

Remote Code Execution (RCE)

In RCE an attacker’s able to execute arbitrary commands or code on a target machine or in a target Machine.

References to read: >https://www.netsparker.com/blog/web-security/remote-code-evaluation-execution/ >https://en.wikipedia.org/wiki/Arbitrary_code_execution

Some POCs:

Insecure Direct Object Reference (IDOR)

In IDOR an application provides direct access to objects based on the user-supplied input. As a result of this vulnerability, attackers can bypass authorization and access resources in the system directly.

Some POCs:

Unrestricted File Upload

As in name unrestricted file upload allows user to upload malicious file to a system to further exploit to for Code execution

Some POCs:

XML External Entity Attack (XXE)

XXE is an attack against an application that parses XML input. This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser.

References to read: >https://portswigger.net/web-security/xxe >https://www.owasp.org/index.php/XML_External_Entity_(XXE)_Prevention_Cheat_Sheet >https://phonexicum.github.io/infosec/xxe.html

Some POCs:

Local File Inclusion (LFI)

The File Inclusion vulnerability allows an attacker to include a file, usually exploiting a “dynamic file inclusion” mechanisms implemented in the target application. The vulnerability occurs due to the use of user-supplied input without proper validation.

References to read: >https://www.owasp.org/index.php/Testing_for_Local_File_Inclusion >https://www.netsparker.com/blog/web-security/local-file-inclusion-vulnerability/ >https://medium.com/@Aptive/local-file-inclusion-lfi-web-application-penetration-testing-cc9dc8dd3601

Some POCs:

Subdomain Takeover

A process of registering a non-existing domain name to gain control over another domain.

This was as much as I can think about sharing with you guys related to Web app Security in tools and vulns i have added a few things about mobile apps but the following sections contain some references you should definitely go through if you gonna join the mobile app security gang as well.

Mobile Application Security.

So hello to Mobile App Security section now let me clear this first i’m a complete noob at this section so it won’t be as detailed as the web app one.

Now The best and the very first thing I would suggest is to actually learn about the development phase of an app mainly my focus is Android APPs ( doesn’t necessarily mean that you should go for learning to develop an android but at least get to know. For this, You can go through the following Android App development tools. (My suggestion is you should actually give basic time to these) Android SDK ~ The Android software development kit (SDK) includes a comprehensive set of development tools. These include a debugger, libraries, a handset emulator based on QEMU, documentation, sample code, and tutorials ADT Bundle ~ The Android Developer Tools(ADT) bundle is a single download that contains everything for developers to start creating Android Application Root Tools ~ RootTools provides rooted developers with a standardized set of tools for use in the development of rooted applications.

Now if you have gone through them let’s get towards Mobile app security vulnerabilities For this I’ll suggest you first go towards OWASP Mobile Top 10 Giving them a good overview will definitely worth it. I’ll also Highly suggest these two Books specifically for Android & IOS app testing The Mobile Application Hacker’s Handbook iOS Application Security: The Definitive Guide for Hackers and Developers

For Mobile Applications, I’ll share Two of the Best places I’m currently following to learn and I would highly recommend you guys to have a look at them and giving them a proper read will definitely help you

Summing up Phase #02 of this blog I think by following these resources at and giving them good time one can get pretty good at Bug Hunting. Here are some Websites or Places where you can play CTF Challenges and practice the skills that you have learned.

Other Resources:

I saw a few friends of mine shared some really interesting and important tools, & resources so I decided to add them here as well because I’m giving some good time to them nowadays.
