Introduction
Have you ever wondered what are the search engines for hackers that use to find vulnerabilities? Well, it is time to read and have a first look at those special search engines. In this article we will publish a list of the most known and unknown search engines used by ethical hackers. Read below to start a career to ethical hacking.
Please Note: Keep hacking legal. We do not encourage illegal hacking of systems. Always report the vulnerabilities to the software owners and avoid any illegal activities.
What is Ethical hacking?
Before talking about ethical hacking, you need to understand who is called “hacker”. Generally, a hacker is the person who tries to find vulnerabilities or bugs in a web or desktop application in order to exploit it.
There is another category of hacker, called black hacker. A black or malicious hacker will try to exploit the vulnerability and keep it secret to ask ransom from the victim. A white or ethical hacker is the one that will report the vulnerability to the victim in order to fix it. Thus, white hacker tries to find application problems, reports the bug to the victim and is compensated accordingly.
Now, Ethical hacking is the “good” side of trying to hack a software or application. We need people with hacking knowledge to find vulnerabilities before they are exploited. So, companies should compensate hackers that report bugs to them.

Useful Hacking Resources
There are many resources available for anyone to start learning penetration testing. A penetration tester is someone who tries to find vulnerabilities in a software. Usually, pentesters use the specific search engines to find internet- exposed systems. Then, they try to find a way to hack them or gain admin priviledges.
A good Github repo with alternative search engines is this one. It contains a large list of various platforms that someone can use for penetration testing.
Another great post with many resources is this reddit article. It contains many useful resources for ethical hackers.
Udemy, guru99 and other learning platforms can give you a good overview on how to become an ethical hacker. Please note that you should not start searching for “how to become a hacker” but start learning how computers and web applications work.
CEH is the most known and best certificate for becoming an Ethical hacker. It is a good starting point for a penetration testing career. However, a lot of practice is the key to become a great pentester.
