This video is about Nuclei by @projectdiscovery:
"Nuclei is a fast tool for configurable targeted vulnerability scanning based on templates offering massive extensibility and ease of use."

Link to Nuclei's Github Repository: https://github.com/projectdiscovery/n...


PREREQUISITES:

~ The only pre-requisite for this tutorial to work and that is to have Go installed on your OS. Here is a guide you can follow to install Go on your operating system(Windows/Mac/Linux):

https://golang.org/doc/install

If you face any problems during the installation of Go, make a comment over here about it or shoot me a Dm on Twitter @BB_Tutorials / @savxiety / @KabirSuda

Installation:
Nuclei:

1. Nuclei Repository: https://github.com/projectdiscovery/n...
2. GO111MODULE=on go get -v github.com/projectdiscovery/nuclei/v2/cmd/nuclei
3. This should install Nuclei correctly, if it didn't do the magic
for you then do comment down below if you're facing any problems.

Nuclei Templates:

1. Nuclei-Templates Repository:
https://github.com/projectdiscovery/n...

2. Go to the /root directory.
3. git clone https://github.com/projectdiscovery/n...
4. Now we have set up Nuclei for Recon. I'll show you how to use
the templates to your advantage.

If you faced any problems in the Installation then comment down
below and we will do our best to help you:)


Testing Nuclei:
1. Create a file targets.txt that must contain the targets to test on
2. cat targets.txt | nuclei -c 100 -silent -t /root/nuclei-templates/ | tee results.txt
3. Then if Nuclei finds anything on your target, it will be
displayed on the screen.

Please note that you should not blindly report everything that
Nuclei gives you. Sometimes it can give false positives too.
So you should always check/verify whatever you find.

TIP: The best way to use Nuclei would be to enumerate target
subdomains with Subfinder as demonstrated in our previous video
and then supply that file to nuclei. This way, nuclei will
start testing on all of the subdomains of the target(s).
