Search Engines For Hackers

This list of search engines for hackers. 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?

A hacker is the person who tries to find vulnerabilities or bugs in a web or desktop application in order to exploit it.

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.

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.

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.
