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
- Automatic handling of duplicate hosts between multiple subdomains
- NMAP Integration for service discovery
- Piped input / output support for integrating in workflows
- Multiple Output formats supported (JSON, File, Stdout)
- Multiple input support including HOST/IP/CIDR notation.
This will display help for the tool. Here are all the switches it supports.
Usage: ./naabu [flags] INPUT: -host string Host to scan ports for -list, -l string File containing list of hosts to scan ports -exclude-hosts, -eh string Specifies a comma-separated list of targets to be excluded from the scan (ip, cidr) -exclude-file, -ef string Specifies a newline-delimited file with targets to be excluded from the scan (ip, cidr) PORT: -port, -p string Ports to scan (80, 80,443, 100-200 -top-ports, -tp string Top Ports to scan (default top 100) -exclude-ports, -ep string Ports to exclude from scan -ports-file, -pf string File containing ports to scan for -exclude-cdn, -ec Skip full port scans for CDNs (only checks for 80,443) RATE-LIMIT: -c int General internal worker threads (default 25) -rate int Rate of port scan probe request (default 1000) OUTPUT: -o, -output string File to write output to (optional) -json Write output in JSON lines Format CONFIGURATION: -scan-all-ips Scan all the ips -scan-type, -s string Port scan type (SYN/CONNECT) (default s) -source-ip string Source Ip -interface-list, -il List available interfaces and public ip -interface, -i string Network Interface to use for port scan -nmap Invoke nmap scan on targets (nmap must be installed) -nmap-cli string nmap command to run on found results (example: -nmap-cli 'nmap -sV') OPTIMIZATION: -retries int Number of retries for the port scan probe (default 3) -timeout int Millisecond to wait before timing out (default 1000) -warm-up-time int Time in seconds between scan phases (default 2) -ping Use ping probes for verification of host -verify Validate the ports again with TCP verification DEBUG: -debug Enable debugging information -v Show Verbose output -no-color, -nc Don't Use colors in output -silent Show found ports only in output -version Show version of naabu -stats Display stats of the running scan

Before installing naabu, make sure to install libpcap library:
sudo apt install -y libpcap-dev
Installing 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.
naabu -host hackerone.com __ ___ ___ ___ _/ / __ __ / _ \/ _ \/ _ \/ _ \/ // / /_//_/\_,_/\_,_/_.__/\_,_/ v2.0.3 projectdiscovery.io [WRN] Use with caution. You are responsible for your actions [WRN] Developers assume no liability and are not responsible for any misuse or damage. [INF] Running SYN scan with root privileges [INF] Found 4 ports on host hackerone.com (104.16.100.52) hackerone.com:80 hackerone.com:443 hackerone.com:8443 hackerone.com:8080
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. It supports following in-built port lists -
| CMD | 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 80,443
The o flag can be used to specify an output file.
naabu -host hackerone.com -o output.txt
To run the naabu on a list of hosts, -list option can be used.
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}
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
The 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 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' __ ___ ___ ___ _/ / __ __ / _ \/ _ \/ _ \/ _ \/ // / /_//_/\_,_/\_,_/_.__/\_,_/ v2.0.0 projectdiscovery.io [WRN] Use with caution.

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 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 to tune the flags / rate if running naabu from local system.
- For best results, run naabu as root user.
