Port Scanning Tools: Beyond Nmap and RustScan

Introduction: Time is a Hacker's Currency

Save some of that time you spend fueled by energy drinks
while waiting for Nmap or RustScan to finish
enumeration. We know time is our greatest enemy as
cybersecurity artists (or professionals, if you prefer).

SPOILERS: The most modern and powerful tools are
at the bottom. While I salute Nmap and RustScan
for their service since the "stone age," it's time to
move on.

Nmap (Network Mapper)

Nmap is a powerful, widely used open-source tool for
network discovery and security auditing. It allows
professionals to identify live hosts, open ports, running
services, operating systems, and potential
vulnerabilities.

Nmap supports a wide range of scanning techniques
(TCP connect, SYN scan, UDP scan, etc.) and is highly
customizable through the Nmap Scripting Engine (NSE),
enhancing its ability to detect misconfigurations.

The Thing is, Nmap is slow. Not so slow, but
slow. Agree to disagree!

RustScan

RustScan is a fast and efficient port scanner built
with the Rust programming language, designed to
significantly speed up the initial port identification
process.

Its key advantage is its incredible scanning speed,
achieved through asynchronous programming and
multi-threading, allowing it to scan thousands of
ports in seconds. It is typically used in combination with
Nmap: RustScan for the initial rapid port scan,
and then passing the results to Nmap for deeper
service and version detection.

Now, we're getting there...

Zenmap (The Graphical Friend)

This is the reason why we are here... Trust me, Zenmap
is very fast!

Like the person Nmap tells you not to worry about,
or Nmap's little friend!

Zenmap is the official Graphical User Interface
(GUI) for Nmap. It's designed to make network
scanning more accessible and user-friendly for those not
comfortable with command-line tools.

Zenmap supports all the powerful features of Nmap
but provides a visual interface for configuring scans,
viewing results in multiple formats (including topology
maps), and saving scan profiles.

For scenarios like "war driving," we can map out the hop
length to our target, useful for channeling attacks and
masking purposes. You can go crazy with it by adding
-d to your script.

ZMap (The Wide-Area Scanner)

ZMap is an open-source network scanner designed
for fast, large-scale Internet scanning. Unlike
traditional scanners like Nmap, which focus on
detailed enumeration of a few hosts, ZMap is
optimized for scanning entire address spaces (like the
whole IPv4 range) at incredible speeds.

Masscan (I Rest My Case Now!)

Masscan is often called the “fastest Internet port
scanner.”

Designed for speed over detail.

While Nmap focuses on deep service enumeration and
scripting, Masscan's job is to find open ports at
massive scale as quickly as possible. It can scan the
entire Internet in under six minutes, generating output
similar to Nmap.
