Web Security & Bug Bounty: Learn Penetration Testing in 2023

  • Another big vulnerability out there and a really dangerous one. Many websites communicate with the Database, whether it being a database that stores product information or user information. If the communication between the user and the database is not filtered and checked, it could allow the attacker to send an SQL query and communicate with the database itself, allowing them to extract the entire database or even delete it. There are couple of types of SQL injection such as Error based or Blind SQL injection.

14) XML, XPath Injection, XXE

  •     XXE or XML External Entity is a vulnerability that allows an attacker to interfere with a website that processes XML data. It could allow the attacker to run a reverse shell or read files on the target system making it another severe vulnerability.

15) Components With Known Vulnerabilities

  • Even if the website might not be vulnerable, the server might be running some other components/applications that have a known vulnerability that hasn’t been patched yet. This could allow us to perform various types of attacks depending on what that vulnerability is.

16) Insufficient Logging And Monitoring

  • Logging and monitoring should always be done from security standpoint. Logging allows us to keep track of all the requests and information that goes through our application. This can help us determine whether a certain attack is taking place or if the attack already happened, it allows us to examine it a little deeper, see which attack it was, and then apply that knowledge to change the application so that the same attack doesn’t happen again.

17) Monetizing Bug Bounty Hunting

  • After practicing and covering all the vulnerabilities, it’s important to mention how we can monetize our knowledge. We mention different platforms that can be used to start your career as a bug hunter, and we also take one platform as an example to show how a bug bounty program looks like and what to pay attention to when applying.

18) Bonus – Web Developer Fundamentals

  • For anyone lacking some knowledge in Web Development or knowledge in how exactly websites work and are structured

19) Bonus – Linux Terminal

  • For anyone lacking some knowledge in simple usage of linux terminal as we will be using it throughout the course

20) Bonus – Networking

  • Fundamentals of networking and some basic terms used as Penetration Testers or Bug Bounty hunters.

We guarantee you this is the most comprehensive online course on bug bounty hunting, penetration testing, and web security skills! Have a look at the course outline video to see all the topics we are going to cover, all the projects we’re going to build, and all the techniques you’re going to learn to become a top penetration tester!

Taught By:

Andrei is the instructor of the highest rated technical courses on Udemy as well as one of the fastest growing. His graduates have moved on to work for some of the biggest tech companies around the world like Apple, Google, Tesla, Amazon, JP Morgan, IBM, UNIQLO etc… He has been working as a senior software developer in Silicon Valley and Toronto for many years, and is now taking all that he has learned, to teach programming skills and to help you discover the amazing career opportunities that being a developer allows in life.

Having been a self taught programmer, he understands that there is an overwhelming number of online courses, tutorials and books that are overly verbose and inadequate at teaching proper skills. Most people feel paralyzed and don’t know where to start when learning a complex subject matter, or even worse, most people don’t have $20,000 to spend on a coding bootcamp. Programming skills should be affordable and open to all. An education material should teach real life skills that are current and they should not waste a student’s valuable time. Having learned important lessons from working for Fortune 500 companies, tech startups, to even founding his own business, he is now dedicating 100% of his time to teaching others valuable software development skills in order to take control of their life and work in an exciting industry with infinite possibilities.

Andrei promises you that there are no other courses out there as comprehensive and as well explained. He believes that in order to learn anything of value, you need to start with the foundation and develop the roots of the tree. Only from there will you be able to learn concepts and specific skills(leaves) that connect to the foundation. Learning becomes exponential when structured in this way.

Taking his experience in educational psychology and coding, Andrei’s courses will take you on an understanding of complex subjects that you never thought would be possible.


Aleksa is a Penetration Tester with over 5 years of experience in Ethical Hacking and Cyber Security. As a self made hacker that started from a young age he has learned it all from Ethical Hacking and Cyber Security to Online Privacy and How To Become Anonymous Online.

He has worked and discovered vulnerabilities for multiple companies and governments. He also worked as a freelancer that tested private web applications. He believes that Online Security and Privacy is something valuable but also that it doesn’t get enough attention as many cyber attacks are being executed every single day! No System is Safe and that is why we are here to discover vulnerabilities and secure them before the bad guys attempt anything malicious!

His main goal as an instructor is to teach the foundations of Ethical Hacking and Cyber Security to anyone who wants to pursue this as a career or wants to learn it to protect themselves online. Cyber attacks and online security is something that changes really fast so we as hackers must always be ready to learn new things in order to better protect Networks, Websites, Machines .. and also people!

See you inside the courses!
