162 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 Passive Port Enumeration using Shodan Internetdb API Optimized for ease of use and lightweight on resources Automatic IP deduplication for port scan NMAP integration for service discovery Multiple input support - STDIN/HOST/IP/CIDR Multiple output format support - JSON/TXT/STDOUTThis will display help for the tool. Here are all the switches it supports.
open ports using shodan internetdb api OPTIMIZATION: -retries int number of retries for the port scan (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 ping probes for verification of host -verify validate the ports again with TCP verification DEBUG: -debug display debugging information -verbose, -v display verbose output -no-color, -nc disable colors in CLI output -silent display only results in output -version display version of naabu -stats display stats of the running scan -si, -stats-interval int number of seconds to wait between showing a statistics update (default 5)">

Before installing naabu, make sure to install libpcap library:

To run the tool on a target, just use the following command.
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.

The ports to scan for on the host can be specified via -p parameter. It takes nmap format ports and runs enumeration on them.
By default, the Naabu checks for nmap's Top 100 ports. It supports following in-built port lists -
| -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.
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.
{"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.
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:-

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 tuning the flags / rate if running naabu from local system. For best results, run naabu as root user.naabu is made with
