Port Scanning Hacking Tools

Port Scanner Tools For 2021

Port Scanning is one of the initial steps that a Penetration Tester (‘Ethical Hacker’) will take to determine how secure a network or web application is from black hat hackers.

Port Scanning Software, of which there is plenty, is a ‘must-learn’ if you are serious about becoming a Cybersecurity Professional. We’ve tried to list as many useful and ‘user-friendly’ Port Scanning Tools that we have used in the past.

What is Network Scanning?

This concept refers to, somewhat obviously, scanning the network! ‘Ports’ on a network can be considered as being the entry points to a machine, or computer (box) that is connected to the Internet. An application or service that listens on port functions by receiving data (bytes) from a client application, processing that data and then sending it back.

If a network is hacked into, or compromised, then a malicious client can be programmed to exploit vulnerabilities in the server code with the purpose of being able to gain access to sensitive data or execute malicious code remotely. The communication and commands would be administered through the implementation of a Remote Access Tool (RAT).

What is Port Scanning?

Network scanning and port scanning are often used interchangeably. Port scanners (of which there are several, such as Angry IP Scanner, NetScanTools, Unicornscan, and NetworkMiner) are used by the system and network administrators to verify security profiles of networks to prevent hackers from being able to identify services running on a host that have exploitable vulnerabilities.

Of course, if a network admin (or any other IT professional) performing a scan discovers a vulnerability then their priority is to patch the hole without delay. Port scanning is a task performed in the initial phase of a penetration test (‘pentest’) in order to establish all network entry points into the target system.

Why Are There So Many ‘Network and Port Scanning’ Tools?

At first, it might seem that there are a ton of ‘similar’ tools.

However, most of these tools serve a particular need, or said in a more technical way, the tools have expertise with regards to certain protocol scanning, for example, some are better at TCP ports scanning rather than UDP ports scanning and vice versa.

Nmap (Network Mapping Tool)
Angry IP Scanner
Netscan Tools
Unicorn Scan

Nmap (Network Mapping Tool)

Nmap is an abbreviation for ‘Network Mapper’ – ‘Network’ in an IT sense of the word. This is a classic hacking tool and perhaps the most famous one on our list.

You can consider Nmap as being one of the best-known, and in fact, one of the most useful hacking tools out there. Period. If you are serious about pentesting, ethical hacking and IT Security in general, then learning Nmap is essential.

Is Nmap Free?

You betcha!

In fact, a lot of other tools out there, Metasploit for example, pulls in Nmap for network discovery and security auditing. Many system admins will use Nmap along with other such tools as Wireshark (and perhaps even ‘Network Miner’) for a wide variety of port and network scanning. If you’re completely new to port and network scanning then we’d suggest this article here.

How does Nmap Work?

Nmap tool works by inspecting raw IP packets in creative ways to understand what hosts (servers) are available on the network, what services (application name and version) those hosts are using, what operating systems (including Operating System versions and possible patches) and what type and version of packet filters/ firewalls are being used by the target. In summary, you’ve got to learn Nmap and if you want to work in Cyber Security as a practitioner.

Does Nmap Work on all Operating Systems?

Yes, Nmap works on all major computer operating systems, and official binary packages are available for Linux, Windows, Mac OS X, IRIX, and AmigaOS. Of course, there’s a much easier way to install Nmap – just use Kali Linux or use BackBox since it ships with Nmap and you’ll be able to update the program with ease.

A Brief word about ‘Zenmap’

Zenmap is the GUI version of Nmap. Here’s our advice: learn how to use Nmap, but when you’re out in the field performing a penetration test etc., then fire-up Zenmap. The awesome thing about Zenmap is that it pre-loads all the command lines in one go so you don’t have to start tapping ‘nmap’ into the command terminal to load the command help prompts.


Angry IP Scanner

Angry IP Scanner is another classic tool that could (and should be) used in tandem with nmap and other similar tools for hacking and monitoring networks. Angry IP Scanner is a cross-platform and, like nmap, is an open-source network scanner created to for fast and efficient deployment.

From our experience, the Angry IP Scanner is very easy to use.

Angry IP Scanner is mostly used by network administrators but it can also be used for penetration testing.

Features of this particular hacking software include IP Range Scanning and being able to exports results in many formats and provide a command-line interface.

Tools that are automated are started by the user and it means that several tools are being used to do the research and then the results will be presented in the users’ web browser.


Unicorn Scan

Unicornscan is another tool that is similar to nmap, Angry IP Scanner, and NetScanTools. This tool works by gathering and correlating datasets for analysis. This hacking software was created to provide an engine that is, according to the developers: “Scalable, Accurate, Flexible, and Efficient”.

It is released for the community to use under the terms of the GPL license.

FAQ

Is Port Scanning Against The Law?

In the US there isn’t a Federal Law that outright bans port scanning using specific tools but you still need to be very careful because your actions would constitute a violation of privacy. Furthermore, performing an authorized port scan of a network using (for example) nmap or a similar hackers tool like that, could get you into a ton of issues within a civil lawsuit capacity. So, the short answer is no – but – it’s technically illegal because it’s a breach of privacy.

What Is A Port Scanning Attack?

A hacker or a Cybersecurity Professional such as an “Ethical Hacker” or a Penetration Tester (with explicit permission) would initiate a port scan to see what’s on the network. A “Port Scanning Attack” is a broad term that implies that an offensive attack has been executed to breach a system, but in reality, a port scan is only an important step within the penetration test.

The actual scan would be done using a port scanning tool like nmap whilst the “attack” would be done by something like Metasploit if a vulnerability is discovered on a specific port. They’d work together, therefore: the scanning would discover what can be hacked and a tool like Metasploit with exploit the discovered vulnerability, assuming that it hadn’t been patched. So, in summary, you’d be using a bunch of tools available o both security professionals as well as hackers.”

What Do Port Scanning Tools And Software Typically Search For?

TCP and UDP are generally the protocols used in port scanning, as previously mentioned and there are several methods of actually performing a port scan with these protocols. The most commonly used method of TCP scanning is SYN scans

The two most common protocols that a port scanning tool would search for would be the obvious (and most commonly found on HTTP), i.e. TCP and UDP. They are both different protocols of course: TCP/IP is really datasets (packets) which constitute the vast majority of internet traffic whilst UDP is generally more for media.

Hacking tools such as nmap is very good at scanning the ports that are associated with these protocols as well as executing the transit of packet formations typically associated with TCP and UDP.

How does using a port scanning tool help a hacker?

Cybersecurity Professionals and “Criminal Hackers” would typically use a port scanning tool and software because it’s a simple way to audit or “discover” what’s on your target’s network. When you know what’s on the network then you can decide on what can (and could) be hacked. Think of port scanning in the same way as conducting an “audit”.

What’s An Average Speed When Executing A Port Scanner?

It’s impossible to calculate “how long” a port scan will take because there is a multitude of variables that dictate the speed and accuracy of a port scan. However, one thing is for certain: the noiser the scan is the more likely that a firewall and security alarms will be triggered. It’s typical for hackers to move slowly and scan even slower to avoid detection.

Are Port Scans Unsafe?

No, they’re not. An innocent scan performing expected pings or sending anticipated TCP/UDP packets will not bring down a network. However, a skillful hacker can manipulate packets (“craft packets”) to test for specific known vulnerabilities on a system.

Is It Possible To Prevent Your Network Being Scanned?

While it’s virtually impossible to prevent your network from all types of port scans, there are best practices available to all that will protect your network. A lot of these tools are provided by Cybersecurity vendors as well as there being open source options. A simple Firewall configured correctly will help prevent “script kiddie” attacks.

Once A Hacker Finds An “Open Port” What Do They Do?

A hacker executes a port scan using a particular software tool to discover ports that shouldn’t be open. Once the hacker (or Security Professional) has discovered an open port then a decision can be made as to whether the service with the open port can be breached and to what outcome.

Why Is It Necessary To Use Proxy In Executing A Scan?

Hiding your tracks is vital for a skilled hacker and that’s why a lot of hackers and “Ethical Hackers” learn the importance of using proxies when using port scanning software.

Rootkit Detectors & Software

FAQ

How Does A Rootkit Work?

A rootkit is a nefarious hacking manner that is malicious software that allows an unauthorized user (hacker) to have privileged access to a computer system and to restricted areas of the operating system. A rootkit typically contains a number of malicious hacking tools such as keyloggers, banking credential stealers, password crackers, antivirus disablers, and for example bot activations for DoS attacks.

A rookit scanning tool works by comparing the files of known “clean” code against a set of differences. Should a difference be found by the tool or software then you can assume that there may have been a compromise of the Operating System.

What Is Meant By Rootkit Scan?

A rootkit scan is performed by a hacking tool (penetration testing tool) to seek indications of the insertion of malicious software by hackers.

Are rootkits against the law?

Malicious or illegal rootkits used by hackers to infiltrate and breach systems are certainly illegal. However, the interesting thing about a rootkit is that on its’ own it is not defined as being specifically “malware”.

Can Rootkits Be Removed?

Rootkits is dangerous software that has the ability to gain root access to your computer and/or network. Whilst there are ways to remove the rootkit from your system, we here at Concise Courses would recommend that you just simply reinstall the Operating System to a known clean version or do a factory reinstall.

What Are Typical Characteristics Of A Rootkit?

Typical characteristics of a rootkit are that they are inserted by a computer hacker against your will and that they can be “persistent”. A persistent rootkit is a typical characteristic in the sense that it will be activated every time the system boots up. The easiest and most effective way of fixing this hack is to simply reinstall the operating system.

How Risky Are Rootkits To A Victim’s Computer?

The danger of a rootkit does not come from the code itself because the purpose of the malicious code is to hide files and processes from other applications as well as the operating system virus scanning tools.

How Does A Hacker Install A Rootkit?

The easiest way would be to have physical access to the victim’s machine. The second easiest way is to send a phishing attack. In reality, there are a dozen different ways for a hacker to get their victim to inadvertently install a rootkit but they all, for the most part, require the victim to inadvertently “help” the hacker by taking an action, for example – by installing an app that looks legitimate but actually contains the rootkit virus.

Is Windows Defender Good At Scanning For Rootkits?

Each time your (Windows) computer boots the “Windows Defender” application will start and by default starts to scan your system automatically which also includes the root architecture of your machine. If any rootkit or virus is detected, the antivirus tool will attempt to remove it automatically.

How Possible Is It That A Rootkit Can Also Infect The BIOS?

A BIOS-level rootkit attack, also known in the Cybersecurity industry as a persistent BIOS attack, is an exploit in which the BIOS of a machine is flashed (which really means updated) with malicious code. A BIOS rootkit is programming that would allow the hacker to have remote administration. The BIOS (basic input/output system) is firmware that every machine has (cross-platform) that resides in memory and is executed each time a computer boots up.

What Computer Languages Are Rootkits Written In?

Operating system startup routines are most likely to be written in C, so drivers are inevitably written in C as well (not C++) meaning that rootkits would also need to be written in the same language. So, the answer is “C”.

FAQ

If My Internet Is Slow Does It Mean The Network Is Hacked?

There are many possible reasons your Internet connection might seem to be slow. Potential problems include issues with your modem or router, Wi-Fi signal, signal strength on your cable line, the number of devices on your network saturating your bandwidth, or even a slow DNS server. It does NOT necessarily mean that someone has installed some sort of hacking network device, software or tool on your network.

Can Wireshark Be Detected On A Network?

You can’t detect a fully passive sniffing tool (such as Wireshark) on the network when in “fully passive” mode because the software uses a network card with its TCP/IP stack disabled. That way the tool card will only listen and never talk, so it’s almost impossible to detect Wireshark.

Vulnerability Scanning Hacker Tools

‘Vulnerability Exploitation Scanning Software’ can make the life of a Pentester easy easier.

However, a good Penetration Tester (‘Ethical Hacker’) will never rely solely on their tools. The ‘human’ and the ‘tool’ when combined can have very difficult results. What is often the case in the corporate world is when a Penetration Test is commissioned by the client they might often request that a second Red Team come into the organization to conduct the same test.

The reason for this is not so much to ensure a competitive atmosphere but rather it is done to compare the results of offensive security teams since it is very likely that the teams will be using the same tools and hacking software that we have listed below.

Sn1per

Sn1per has generated a lot of buzz, mostly because it just works great; runs smoothly and is designed to be an efficient tool that enumerates and scans for vulnerabilities. This hacking tool comes in three flavors: a Community Edition and paid versions (Professional and Enterprise).

You can check out their site for more information.

Sn1per, much like Metasploit, is integrated with many other popular hacking tools such as Nmap, THC Hydra, nbtscan, w3af, whois, nikto and of course WPScan. WPScan is particularly important because at the last check 33% of web CRM’s are WordPress.

How Does It Work?

Sn1per works by automating a bunch of processes that collect basic recon on a target domain, (for example executing dorks search parameters, enumerating open ports, scanning for a known web app for vulnerabilities, brute-forcing open servicing – and a lot more).

Much like Nmap, you can set the tool to be noisy or stealth.

We’d absolutely recommend this tool and would advise using it as an initial “what’s what” out there to garner some intel on a target during the initial stages of engagement (pentest).

(We should really place this tool in our Multi-Purpose Tools section!)

Nipper

Nipper Studio processes the devices’ native configurations during a network audit and enables users to create various audit reports.

Using traditional methodology for your network audits, such as Agent-based software and Network Scanners or manual Penetration Testing, you could experience various drawbacks, which does not affect Nipper Studio security audit software. These network scanners send large numbers of network probes to a device and can impact performance. Only the exposed vulnerabilities are verified, potentially missing many issues.

Agent-based audit software requires software to be installed on the devices during the network audit. This is not possible for all devices and can introduce additional security vulnerabilities.

Manual Penetration Tests checks individual network devices in detail. However, this is slow, expensive and results in point in time audits of only a sample of devices.

FAQ

What is a Web Proxy?

The point of being a hacker is that you don’t get caught! So, a web proxy is one way to try to anonymize yourself. Spoofing mac addresses is just as important but for the purpose of this answer let’s define a web proxy as being a method used by hackers and “Ethical Hackers” to hide their IP addresses from the websites they visit (when hacking or auditing).

What is a Web Proxy Server?

A web proxy server acts as a gateway between you and the internet at large. Most modern proxy servers are able to execute a bunch more functions but in essence, their main purpose is to forward web requests. The additional benefit of proxy servers is that they also act as a firewall and web filter, provide shared network connections, and cache data to improve loading speeds.
