naabu is a port scanning tool written in Go that allows you to enumerate valid ports for hosts in a fast and reliable manner. It is a really simple tool that does fast SYN scans on the host/list of hosts and lists
all ports that return a reply.
Inspired by the great furious project of @liamg.

Direct Installation
Linux
There are various ways to install the tool on linux. You can install it via docker,
directly go get it or download and run the binary.
From Source
naabu requires go1.13+ to install successfully. Run the following command to get the repo -
GO111MODULE=on go get -v github.com/projectdiscovery/naabu/cmd/naabu
You also need the following libraries installed for the go get to work - libpcap, libpcap-dev.
On Ubuntu linux libpcap is installed by default. For those compiling from source, the header files can be installed by using apt-get install libpcap-dev.
From Binary
The installation is easy. You can download the pre-built binaries from the Releases page. Extract them using tar, move it to your $PATH and you're ready to go.
> tar -xzvf naabu-linux-amd64.tar
> mv naabu-linux-amd64 /usr/bin/naabu
> naabu
From Docker
You can use the official dockerhub image at naabu. Simply run -
> docker pull projectdiscovery/naabu
The above command will pull the latest tagged release from the dockerhub repository.
If you want to build the container yourself manually, git clone the repo, then build and run the following commands
- Clone the repo using
git clone https://github.com/projectdiscovery/naabu.git - Build your docker container
docker build -t projectdiscovery/naabu .
- After building the container using either way, run the following -
docker run -it projectdiscovery/naabu
The above command is the same as running
-h
For example, this runs the tool against hackerone.com and output the results to your host file system:
docker run -it projectdiscovery/naabu -host hackerone.com > hackerone.com.txt
MacOS
On MacOS, the install instructions are similar to linux. You can download a binary for MacOS from the releases page. You can also go get the package to install it from source.
You need libpcap library on MacOS to build successfully from source or run the downloaded binary. If you are using homebrew as your package manager, you can run brew install libpcap to download and install it in your system.
After that, you can just run the following command to download and install naabu -
go get -v github.com/projectdiscovery/naabu/cmd/naabu
See the From Docker section for install instructions on MacOS with docker.
Windows
Windows version is currently not usable without docker.
The docker install instructions are identical to the ones for other platforms. See the From Docker section for install instructions on Windows.
Running Naabu
To run the tool on a target, just use the following command.
> naabu -host hackerone.com
This will run the tool against hackerone.com. There are a number of configuration options that you can pass along with this command. The verbose switch (-v) can be used to display verbose information.
[INF] Starting scan on host hackerone.com (104.16.100.52)
[INF] Found 4 ports on host hackerone.com (104.16.100.52) with latency 25.46362ms
hackerone.com:443
hackerone.com:8443
hackerone.com:80
hackerone.com:8080
The ports to scan for on the host can be specified via -ports parameter. It takes nmap format ports and runs enumeration on them.
> naabu -ports 80,443,21-23 -host hackerone.com
By default, the tool checks for nmap's Top 100 ports. It supports following in-built port lists -
top-100- Checks for nmap top 100 ports.top-1000- Checks for nmap top 1000 ports.full- Checks for 1-65535 ports.
You can also specify a file which contains the ports to scan for using the pL format. You can also specify specific ports which you would like to exclude from the scan.
> naabu -ports full -exclude-ports 80,443
The -o command can be used to specify an output file.
> naabu -host hackerone.com -o output.txt
To run the tool on a list of hosts, -hL option can be used. This requires a directory to write the output files. Ports for each host from the list are written in a text file in the directory specified by the -oD flag with their name being the host name.
> cat hosts.txt
hackerone.com
google.com
> naabu -hL hosts.txt -oD ~/path/to/output
> ls ~/path/to/output
hackerone.com.txt
google.com.txt
If you want to save results to a single file while using a domain list, specify the -o flag with the name of the output file.
> cat hosts.txt
hackerone.com
google.com
> naabu -hL hosts.txt -o ~/path/to/output.txt
> ls ~/path/to/
output.txt
You can also get output in json format using -oJ switch. This switch saves the output in the JSON lines format.
> naabu -host hackerone.com -oJ -o output.json
> cat output.json
{"host":"hackerone.com","port":8443}
{"host":"hackerone.com","port":443}
{"host":"hackerone.com","port":8080}
{"host":"hackerone.com","port":80}
The -silent switch can be used to show only ports found without any other info.
Hosts can also be piped to naabu and port enumeration can be ran on them. For example -
> echo "hackerone.com", naabu
> cat targets.txt, naabu
The ports discovered can be piped to other tools too. For example, you can pipe the ports discovered by naabu to the awesome httprobe tool by @tomnomnom which will then find running http servers on the host.
> echo "hackerone.com", naabu -silent, httprobe
http://hackerone.com:8443
http://hackerone.com:443
http://hackerone.com:8080
http://hackerone.com:80
If you want a second layer validation of the ports found, you can instruct the tool to make a TCP connection for every port and verify if the connection succeeded. This method is very slow, but is really reliable. This is similar to using nmap as a second layer validation
> naabu -host hackerone.com -verify
The most optimal setting for threads is 10. Increasing it while processing hosts may lead to increased false positive rates. So it is recommended to keep it low.
