Introduction to the course.
Computer hacking is a sensitive topic, so there is nothing without a disclaimer.
Everything
in this course is my private opinion and product. My employer has no connection
to it.
Introduction to the methodology of security assessments and what is covered by this course.
Introduces the contents of this section.
Download all the resources for the rest of the course.
We will setup the target server, which we will attack in the following sections.
We will install Kali linux, which we will use throughout the course.
We will install the newest Burp Suite in our Kali.
You will learn about the HTTP protocol, which is in the core of the web. You will be able to understand HTTP communication.
Starting from the basics of web sites you will learn how HTML works.
We will write a simple PHP page to understand how that and similar technologies work.
We will write a simple MVC application in python with Django, to get a general understanding about modern web frameworks.
We will write Javascript to understand its concept.
How to map the application manually.
We will learn about tools, which can help you in the discovery process.
Introduction to how session management works in web applications.
You will learn about session fixation vulnerabilities and how to exploit them.
You will learn about why logout is critical in session management.
You will learn about the Same Origin Policy, which is one of the most important security measures of browsers. Understanding how it works is necessary to be able to attack it.
Cross-site request forgery is one of the most important vulnerabilities in web applications. You will learn about it everything you need to know in this lecture.
You will learn, what to recommend to your customers when they suffer from session management problems.
The corner stone of today's encryption is SSL/TLS, we will learn everything you need to know about it.
We are going to try some authentication bypass attacks.
Getting access to the application in the most simple way, and it surprisingly works.
We need to talk about password quality because it is still a problem.
You will learn how to do password brute force attacks against web applications.
Defaults were always the friend of attackers, you will learn why.
There are various ways to recover passwords. Not all of them are secure. You will see here why.
We will learn how to prevent authentication problems.
Typical error is to find feature, authorization is not implemented correctly.
Trusting the client side is always a problem. We will learn how to exploit this trust in web applications.
Again, never trust the client, especially with authentication.
We will learn how to prevent authorization problems.
Silver bullet of web applications. In this lecture you will learn how to exploit reflected cross-site scripting vulnerabilities.
Golden bullet (if there is anything like that) of web applications.
We will learn how HTTP headers can be used in attacks.
Redirects are innocent, right? We will learn here why they aren't.
Various attacks are possible if the content type is wrong. We will experiment with these.
Fortunately for the world there are new security protections against various attacks. We will learn about some of them in this lecture.
File upload is always interesting. Many things can go wrong, which we will learn how to exploit.
Local and Remote File Inclusion can give you code execution on the server. We will learn how.
Applications sometimes allow code execution in the OS if we can find it. We will find it.
This vulnerability exists since decades and it doesn't want to go away. We will learn how it works and how to exploit it.
UNION Select is a special case of SQL injection which can be really useful when extracting data.
Exploiting blind SQL injection vulnerabilities is difficult, but we will learn how to do it.
SQL injections can be time consuming. We will learn how to save some time using tools and automation.
Quality report is a very important thing if you are doing this professionally. I will give you some tips about how to make a good report.
In this lecture we will learn about how to use my checklist in security assessments.
We will talk about what you should do to after this course.
This course contains everything to start working as a web pentester. You will learn about exploitation techniques, hacking tools, methodologies, and the whole process of security assessments. It is absolutely hands-on, you will do all the attacks in your own penetration testing environment using the provided applications. The targets are real open-source software. You will have to work hard but at the end you will be able to do web security assessments on your own as a real ethical hacker.
My name is Geri and I am the instructor of this course about web application hacking. If you are interested in hacking and IT security, then this is the perfect place to start. You might be a developer, an IT administrator, or basically anybody with an IT background. With this training you will get everything you need to start working as a professional web penetration tester.
But why would you want to become one? First of all because it is lot's of fun. You can be in the position of an attacker trying to hack various system. Finding vulnerabilities exploiting them and taking over the system. You can find the true hacker in yourself. It is a very creative and exciting job.
Also the security business is booming now. I get offers every day on LinkedIn, because there is a serious shortage of penetration testers. As companies figure out that they really have to care about security they face the problem that they cannot find people to do that. And it just keeps growing. And because of that you can earn pretty well even as a white hat ethical hacker, so there is no reason to go to the dark side.
But why should you learn web hacking. Mostly because there is the biggest demand on the market. Wherever you go to work right now as a penetration tester, around 80 % of the projects are web hacking related. This usually because the awareness of web security was already established and because basically everything has a web interface from web application to embedded devices or IoT. Also because that is the fastest to learn. It is because web related technologies are usually text based and are easy to work with. So at the end of the day web pentesting is the fastest to learn and the most searched for so I think it is an obvious choice to start your carrier there.
But who am I to teach that, you might ask. I work as a penetration tester in Germany. I am lucky to work with the extremely wide spectrum of technologies in my day job.
I also talk on conferences, when I have the time (google my name).
And I have already made an online hacking course which has 20000+ students, and people seemed to like it.
But most importantly I know how to become a penetration tester because I did it myself. I was a software quality engineer when I decided to change to pentesting. I did trainings read books to become one. But when I designed this ethical hacking course I tried to figure out what are the most important things you need, based on my own experience. I analysed what I needed the most to become a pentester and also what we are looking for, when we hire somebody in our team. And I put these topics in this course. So if you learn everything in this ethical hacking course, then I would be glad to work with you, because I would know that I can trust you with doing a web assessment.
So how is this course looks like. It is absolutely hands on. We are gonna hack real open source applications where you can try every technique and attack yourself. So you will have to get your hands dirty. I will show you everything first and then you can keep experimenting and testing yourself.
Of course this course is the essentials. I don't like the idea of people calling courses the "complete whatever". In IT generally there is no such thing as complete. There are new systems and technologies born everyday. You will have to learn forever and your knowledge will never be complete. But that is good for two reasons:
So I hope I piqued you attention, to learn web application hacking and becoming an ethical hacker. But if you don't believe me here is what my students say:
"The instruction is hitting some key elements to test for web apps and in the process providing some useful tips when using Burp." - Danny Rogers
"I watched first time all video - and didn't see 10% of the value LOL shame on me. But over now that am doing exercises i see how much and how powerful this course - thank you Geri!!" - ARturs Stays
"Dude you are awesome. Teach me!!!! Teach me!!!!!" - Rubem
"A very well developed and presented course." - Steve Hinesly
So join now and let's get hacking.
