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/CONNECT scans on the host/list of hosts and lists all ports that return a reply.
- Fast And Simple SYN/CONNECT probe based scanning
- Optimized for ease of use and lightweight on resources
- DNS Port scan
- Automatic IP Deduplication for DNS port scan
- IPv4/IPv6 Port scan (experimental)
- Passive Port enumeration using Shodan Internetdb
- Host Discovery scan (experimental)
- NMAP integration for service discovery
- Multiple input support - STDIN/HOST/IP/CIDR/ASN
- Multiple output format support - JSON/TXT/STDOUT

Note: before installing naabu, make sure to install
libpcaplibrary for packet capturing.
To install libcap on Linux: sudo apt install -y libpcap-dev, on Mac: sudo brew install libpcap
go install -v github.com/projectdiscovery/naabu/v2/cmd/naabu@latestTo run the tool on a target, just use the following command.
naabu -host hackerone.comThis 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

hackerone.com:80
hackerone.com:443
hackerone.com:8443
hackerone.com:8080The 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.comBy default, the Naabu checks for nmap's Top 100 ports. It supports following in-built port lists -
| Flag | Description |
|---|---|
-top-ports 100 |
Scan for nmap top 100 port |
-top-ports 1000 |
Scan for nmap top 1000 port |
-p - |
Scan for full ports from 1-65535 |
You can also specify specific ports which you would like to exclude from the scan.
naabu -p - -exclude-ports 80,443To run the naabu on a list of hosts, -list option can be used.
naabu -list hosts.txtTo run the naabu on a ASN, AS input can be used. It takes the IP address available for given ASN and runs the enumeration on them.
echo AS14421 | naabu -p 80,443
216.101.17.249:80
216.101.17.249:443

216.101.17.251:443
216.101.17.250:443
216.101.17.250:80You can also get output in json format using -json switch. This switch saves the output in the JSON lines format.
naabu -host 104.16.99.52 -json
{"ip":"104.16.99.52","port":443}
{"ip":"104.16.99.52","port":80}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:80The speed can be controlled by changing the value of rate flag 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.
Naabu supports both IPv4 and IPv6. Both ranges can be piped together as input. If IPv6 is used, connectivity must be correctly configured, and the network interface must have an IPv6 address assigned (inet6) and a default gateway.
echo hackerone.com | dnsx -resp-only -a -aaaa -silent | naabu -p 80 -silent
104.16.99.52:80
104.16.100.52:80
2606:4700::6810:6434:80
2606:4700::6810:6334:80The option -ip-version 6 makes the tool use IPv6 addresses while resolving domain names.
echo hackerone.com | ./naabu -p 80 -ip-version 6

hackerone.com:80Naabu optionally supports multiple options to perform host discovery, as outlined below. Host discovery is completed automatically before beginning a connect/syn scan if the process has enough privileges. -sn flag instructs the toll to perform host discovery only. -Pn flag skips the host discovery phase. Host discovery is completed using multiple internal methods; one can specify the desired approach to perform host discovery by setting available options.
Available options to perform host discovery:
- ARP ping (
-arp) - TCP SYN ping (
-ps 80) - TCP ACK ping (
-ps 443) - ICMP echo ping (
-pe) - ICMP timestamp ping (
-pp) - ICMP address mask ping (
-pm) - IPv6 neighbor discovery (
-nd)
Naabu supports config file as default located at $HOME/.config/naabu/config.yaml, It allows you to define any flag in the config file and set default values to include for all scans.
We have integrated nmap support for service discovery or any additional scans supported by nmap on the found results by Naabu, make sure you have nmap installed to use this feature.
To use,nmap-cli flag can be used followed by nmap command, for example:-
echo hackerone.com | naabu -nmap-cli 'nmap -sV -oX nmap-output'

PORT STATE SERVICE VERSION
80/tcp open http cloudflare
443/tcp open ssl/https cloudflare
8080/tcp open http-proxy cloudflare
8443/tcp open ssl/https-alt cloudflareNaabu 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.
The following sample program scan the port 80 of scanme.sh. The results are returned via the OnResult callback:
package main
import (
"log"
"github.com/projectdiscovery/goflags"
"github.com/projectdiscovery/naabu/v2/pkg/result"
"github.com/projectdiscovery/naabu/v2/pkg/runner"
)
func main() {
options := runner.Options{
ResumeCfg: &runner.ResumeCfg{},
Retries: 1,
Host: goflags.StringSlice{"scanme.sh"},
OnResult: func(hr *result.HostResult) {
log.Println(hr.Host, hr.Ports)
},
Ports: "80",
}
naabuRunner, err := runner.NewRunner(&options)
if err != nil {
log.Fatal(err)
}
defer naabuRunner.Close()
naabuRunner.RunEnumeration()
}- Naabu allows arbitrary binary execution as a feature to support nmap integration.
- Naabu is designed to scan ports on multiple hosts / mass port scanning.
- As default naabu is configured with a assumption that you are running it from VPS.
- We suggest tuning the flags / rate if running naabu from local system.
- For best results, run naabu as root user.
Naabu is made with 🖤 by the projectdiscovery team. Community contributions have made the project what it is.
