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.

The installation is easy. You can download the pre-built binaries for your platform from the releases page. Extract them using tar, move it to your $PATH
and you're ready to go.
Download latest binary from https://github.com/projectdiscovery/naabu/releases
▶ tar -xvf naabu-linux-amd64.tar
▶ mv naabu-linux-amd64 /usr/local/bin/naabu
▶ naabu -h
naabu requires go1.14+ to install successfully. Run the following command to get the repo -
▶ GO111MODULE=on go get -u -v github.com/projectdiscovery/naabu/v2/cmd/naabu
▶ git clone https://github.com/projectdiscovery/naabu.git; cd naabu/v2/cmd/naabu; go build; mv naabu /usr/local/bin/; naabu -h
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.
- After pulling / 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
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.
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.
▶ naabu -host hackerone.com

[INF] Running TCP/ICMP/SYN scan with root privileges
[INF] Fastest host found for target: 104.16.99.52 (1.86764ms)
[INF] Found 4 ports on host hackerone.com (104.16.99.52)
hackerone.com:8080

hackerone.com:8443
The ports to scan for on the host can be specified via -p
parameter. It takes nmap format ports and runs enumeration on them.
▶ naabu -p 80,443,21-23 -host hackerone.com
By default, the Naabu checks for nmap's Top 100
ports after a host discovery phase like nmap, that can be skipped by using the -no-probe
flag. It supports following in-built port lists -
-top-ports 100
- Checks for nmap top 100 ports.-top-ports 1000
- Checks for nmap top 1000 ports.-p -
- Checks for all ports from1-65535
.
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 -p - -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 naabu on a list of hosts, -iL
option can be used.
▶ naabu -iL hosts.txt
You can also get output in json format using -json
switch. This switch saves the output in the JSON lines format.
▶ naabu -host hackerone.com -json
{"host":"hackerone.com","ip":"104.16.99.52","port":8443}
{"host":"hackerone.com","ip":"104.16.99.52","port":80}
{"host":"hackerone.com","ip":"104.16.99.52","port":443}
{"host":"hackerone.com","ip":"104.16.99.52","port":8080}
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 httpx
which will then find running http servers on the host.
▶ echo hackerone.com | naabu -silent | httpx -silent
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 speed can be controlled by changing the value of rate
that represent the number of packets per second. Increasing it while processing hosts may lead to increased false-positive rates. So it is recommended to keep it to a reasonable amount.
We have added support for config file, it allows each and every flag to define in config file, so you don't have to write them everytime, it's optional and not used on default run, default location of config file is $HOME/.config/naabu/naabu.conf
, custom config file can be provided using config
flag.
Example config file
# Number of retries
# retries: 1
# Packets rate
# rate: 100
# Timeout is the seconds to wait for ports to respond
# timeout: 5
# Hosts are the host to find ports for
# host:
# - 10.10.10.10
# Ports is the ports to use for enumeration
# ports:
# - 80
# - 100
# ExcludePorts is the list of ports to exclude from enumeration
# exclude-ports:
# - 20
# - 30
# Verify is used to check if the ports found were valid using CONNECT method
# verify: false
# NoProbe skips probes to discover alive hosts
# no-probe: false
# Ping uses ping probes to discover fastest active host and discover dead hosts
# ping: true
# Port Probes (SYN-PORT, ACK-PORT)
# port-probes:
# - A80
# - S110
# Ips or cidr to be excluded from the scan
# exclude-ips:
# - 1.1.1.1
# - 2.2.2.2
# Top ports list
# top-ports: 100
# Attempts to run as root
# privileged: true
# Drop root privileges

# icmp-echo-probe: true
# IcmpTimestampProbe before scanning
# icmp-timestamp-probe: false
# SourceIP to use in TCP packets
# source-ip: 10.10.10.10
# Interface to use for TCP packets
# interface: eth0
# WarmUpTime between scan phases
# warm-up-time: 2
# nmap command to invoke after scanninginvoke after scanning
# nmap: nmap -sV
We have integrated nmap support with nmap
flag and config file, in config file you can define any nmap
command you wish to run on the result of naabu, make sure you have nmap
installed to use this feature.
To make use of nmap
flag, make sure to remove the comments from the config file at $HOME/.config/naabu/naabu.conf
nmap: nmap -sV -oX naabu-output
▶ echo hackerone.com | naabu -nmap

Naabu also supports excluding CDN IPs being port scanned. If used, only 80
and 443
ports get scanned for those IPs. This feature can be enabled by using exclude-cdn
flag.
Currently cloudflare
, akamai
, incapsula
and sucuri
IPs are supported for exclusions.
naabu is made with 🖤 by the projectdiscovery team. Community contributions have made the project what it is. See the Thanks.md file for more details.
