15 Vulnerable Sites You Can Legally Hack (Websites for Hacking)

Last Updated on May 15, 2024

New wannabe hackers need websites for hacking as practice.

Did you know that software and websites are just like human bodies? That’s right. They both get stronger with frequent updates. Think about it: the way the immune system of a body strengthens is if it encounters disease-causing germs. The immune system then learns from it. It guards the body henceforth.

Similarly, a website or software gets stronger the more problems you throw at them. This is to ensure that the vulnerabilities of the software are known to the developer. It is only then that the developer can prepare for such problems and make the product stronger.

However, it is not necessary that you need to have your own website to find and learn about vulnerabilities. Thanks to technology and the products we have to offer, there are several apps and websites to try your hand at hacking. This will then enable you to understand the problems you might have to overcome while building a great website.
