NetworkSherlock is a powerful and flexible port scanning tool designed for network security professionals and penetration testers. With its advanced capabilities, NetworkSherlock can efficiently scan IP ranges, CIDR blocks, and multiple targets. It stands out with its detailed banner grabbing capabilities across various protocols and integration with Shodan, the world’s premier service for scanning and analyzing internet-connected devices. This Shodan integration enables NetworkSherlock to provide enhanced scanning capabilities, giving users deeper insights into network vulnerabilities and potential threats. By combining local port scanning with Shodan’s extensive database, NetworkSherlock offers a comprehensive tool for identifying and analyzing network security issues.

Example Usage

Basic Port Scan

Scan a single IP address on default ports:

python networksherlock.py 192.168.1.1

Custom Port Range

Scan an IP address with a custom range of ports:

python networksherlock.py 192.168.1.1 -p 1-1024

Multiple IPs and Port Specification

Scan multiple IP addresses on specific ports:

python networksherlock.py 192.168.1.1,192.168.1.2 -p 22,80,443

CIDR Block Scan

Scan an entire subnet using CIDR notation:

python networksherlock.py 192.168.1.0/24 -p 80

Using Multi-Threading

Perform a scan using multiple threads for faster execution:

python networksherlock.py 192.168.1.1-192.168.1.5 -p 1-1024 -t 20

Scanning with Protocol Selection

Scan using a specific protocol (TCP or UDP):

python networksherlock.py 192.168.1.1 -p 53 -P udp

Scan with Shodan

python networksherlock.py 192.168.1.1 --use-shodan

Banner Grabbing and Save Results

Perform a detailed scan with banner grabbing and save results to a file:

python networksherlock.py 192.168.1.1 -p 1-1000 -V -s results.txt

Ping Check Before Scanning

Scan an IP range after performing a ping check:

python networksherlock.py 10.0.0.1-10.0.0.255 -c
