25+ Vulnerable websites to practice your ethical hacking skills

best Vulnerable websites to Practice your Hacking Skills

Recently, as the field of information is on the rise, a new term, ‘Ethical Hacking’, has emerged and opened many different avenues for IT and cyber security professionals. Now more and more people are getting familiar with the information security field and are interested in learning about hacking skills. This article relates to websites for hacking skills where one can practice and practice. Learning never stops, and an ethical hacking career demands constant understanding and skill-set upgrade.

For budding hackers, these are often the best way to hit the ground running in case of career choices towards penetration testing or vulnerability assessment and pen testing (VAPT)

What is ethical hacking?

Ethical hacking is identifying vulnerabilities in computer systems and networks and using that information to help improve security. Ethical hackers use their skills to find and fix security problems before malicious actors can exploit them.

Hacking in the IT world means gaining unauthorised Access to a computer system and making any software or hardware technology perform tasks that are not intended.

Ethical hacking is the same concept of gaining unauthorised access to systems but with the explicit permission of the system owner. An ethical hacker finds security vulnerabilities and flaws in a company’s IT infrastructure and reports them back to the stakeholders or relevant personnel for remediation. 

This proactive practice helps organisations identify vulnerabilities in their environment and patch them before a malicious attacker finds the opportunity to exploit them.

Before the websites hacking drill, understand ethical hacking techniques

Many hacking skills, techniques, and methodologies are followed. Generally, when hacking any system, it comes down to following 5 phases of hacking and then expanding upon them. The phases of hacking are:

1. Reconnaissance

In this phase, the ethical hacker tries to gather all the possible information about the target assets. This includes finding out what type of technologies are being used, what kind of network architecture is implemented, IP addresses, DNS records, MX records, subdomains etc. are all noted down in the information-gathering phase.

2. Scanning

Next, the ethical hacker should then perform scans of the information gathered and locate vulnerabilities. Scanning includes port scans for available services, website scanning, server scanning etc. This phase yields any potential vulnerabilities that can be exploited.  

3. Gaining Access

Now that the ethical hacker has a list of possible vulnerabilities, the actual exploitation or hacking happens in this phase. The ethical hacker launches a full-fledged attack on the assets using the information gained in the previous two phases.

4. Maintaining Access

In the case of ethical hacking, this step is optional. If the ethical hacker has enough information to display the impact of the vulnerability, then he does not need to create persistent access in the target company. 

However, if the ethical hacker needs to come back and continue his tasks on the compromised system whenever needed, then he can deploy software programs to create backdoors and continue the security assessment. 

5. Clearing tracks

Clearing tracks means that in this step, the hacker removes all traces of this attack from the organisation’s systems, such as eliminating any logs, deleting any files he created, uninstalling any applications etc.

Types of ethical hacking

There are many technologies out in the world right now, from basic web applications and web servers to Internet of things devices like smart TVs, Cars etc. Each one of these technologies can be hacked under ethical hacking. 

Different Types of ethical hacking


A few of the areas in which an ethical hacker can build their hacking skills are:

Application hacking

Application hacking mainly focuses on vulnerable web apps, mobile apps such as Jailbreaking security risks and APIs. An ethical hacker tried to find vulnerabilities in these technologies. Vulnerabilities like SQL injection, Cross-site request forgery (CSRF), Cross-site Scripting XSS etc., are common bugs. OWASP is an excellent resource that launches the top 10 vulnerabilities that can be found in each domain.

Web Server hacking

Web servers host the application we see every day; these servers are a prime target for malicious hackers and need to be tested to ensure there is no existing vulnerability. In professional life, these are often validated via build and configuration reviews or hacking is simulated via web application security testing

Wireless network hacking

Wireless network hacking skills consists of testing wireless access points and networks for security weaknesses. See our wireless penetration testing to read more on how businesses can benefit from the validation of wireless network security controls. 

Network hacking

Ethical hackers can try to compromise the entire network of a company and gain unauthorised access to the company’s network. Network or infrastructure hacking is a wide area and comprises of various sub-domains such as internal infrastructure covering active directory security checks, external infrastructure, remote connectivity, individual security devices such as routers, SSLs VPNs, firewalls and WLAN controllers.

System hacking

If the network configurations are secure then the systems on the network should also be secure. System hacking skills consists of an ethical hacker targeting all systems like desktops, servers, laptops, mobile devices etc. inside an organisation to gain AAccess.

Social engineering

Social engineering techniques are used to hack humans. What this means is that hackers exploit the trust of humans and trick them into believing and handing over sensitive information and credentials. Phishing is an example of social engineering.

IoT hacking

IoT hacking is the next big thing in IT, this includes hacking devices that are connected to the Internet that are not primarily computer systems. 

Is ethical hacking legal?

Even though looking at the definition of ethical hacking one could see that gaining unauthorised AAccess may be wrong, ethical hacking is a completely legal job.

There is some overlap in the methodology of a black hat hacker and an ethical hacker but there is a fundamental difference that all activities carried out during ethical hacking are approved and trusted by the organisation. Not to mention that criminal hackers work with the intent to harm the target organisation whereas the ethical hacker works closely with the team to protect the organisation.

Is ethical hacking a good career?

Ethical hacking is a good career choice because it offers a lot of job security and pays decent. The demand for ethical hackers is increasing as companies become more aware of the importance of cybersecurity. There are many different types of ethical hacking jobs, so you can find a position that suits your skills and interests.

If you’re interested in a career in ethical hacking, there are a few things you should know. First, you need to have strong technical skills. You’ll need to be able to find and exploit vulnerabilities in systems. You’ll also need to be able to write code and reverse engineer software. Second, you need to be good at problem-solving. Ethical hackers need to be able to think creatively to solve challenges. Finally, you need to be detail-oriented.

What is a vulnerable site?

As we covered in the section above, it is important for an ethical hacker to acquire permission from the owner before performing any tests or launching any attack, otherwise, the activity will be considered illegal.

For this reason, it can become difficult for beginners to practice and build their hacking skills since they can not just pick any target at random and launch attacks. This is where intentionally vulnerable applications come into play. Organisations like OWASP, Hack the Box, Over the Wire etc. create vulnerable web applications for beginners to practice their hacking skills legally within a safe environment. 

Vulnerable websites to practice your skills

There are many online platforms available that give users AAccess to vulnerable websites for practising their hacking skills. Some of these websites for hacking skill-set practice are listed below:

Hack The Box

Hack The Box (HTB) has taken the cyber security community by storm and is one of the most widely used platforms by students, new hackers and security professionals. HTB provides vulnerable machines named “boxes” with multiple severity levels.

The hacker has to exploit the machines and gain root access or admin access in order to retrieve flags and complete the machine. The machines are hosted by HTB and the users have to access them by connecting to the HTB network via VPN.

These machines along with individual challenges provide a real-world scenario for performing penetration tests. HTB also has an active community, where members help and exchange ideas without giving any spoilers.


The concept of VulnHub is somewhat similar to that of HTB. Vulnhub provides new hackers with 100s of vulnerable virtual machines with practical and hands-on experience for learning to hack. Unlike HTB where users are required to connect to the HTB network via VPN, Vulnhub provides machines that can be downloaded as virtual machine files and the users can deploy them in their local systems to carry out the hacking activities.


EchoCTF provides a Capture with the Flag environment for the users where they can practice their hacking skills in a controlled environment. The attack simulations are based on real-life scenarios, systems and services. By solving the CTFs users gain points and can showcase their progress. 


TryHackMe is another great resource for up and coming hackers. They provide a learning platform in the form of “Rooms”. Each room has certain vulnerabilities for users to exploit. Another unique feature of TryHackMe is that they provide learning scenarios for both the offensive and defensive sides of security. So users can learn to attack and defend systems simultaneously.

Other than this TryHackMe provides beginner to advanced learning paths, in which they have clubbed the relevant rooms into a short training course. TryHackMe also has a competition where you can compete with other players to see who can hack the machine the fastest and then try to stop other hackers from penetrating in, this is called the King of the Hill.


OverTheWire offers wargames and war zones of different skill levels to its users. Apart from getting directly into hacking skills, OverTheWire offers beginner level training such as in their Bandit wargame about how basic Linux commands work. 

In the wargames, users will cover the basic concepts and skills first and then can practice different scenarios and stories to improve their hacking skills. Other than this OverTheWire also has competitions called warzones, where players can compete with other hackers in compromising a machine.

Security Shepherd 

Security Shepherd is a vulnerable project from OWASP which targets web app vulnerabilities and mobile app vulnerabilities. The project can be downloaded from GitHub and can be set up locally on your machine.

The hackers can then solve multiple challenges and improve their skills. Hints are also available for users if they get stuck. The challenges focus on learning the OWASP top 10 along with other common vulnerabilities.

Port Swigger

Port Swigger is the developer of the most widely used application security tool i.e. Burp Suite. Recently they have launched their Web Security Academy which contains detailed descriptions for many web application vulnerabilities along with online labs that help you practice the learnt flaws.
