This tool is very useful for network exploration and security auditing. So let’s see how to install and work with Nemap on Kali Linux.

What is Nmap?

Nmap is a well-known and practical tool for exploring the network, which is also widely used in terms of security. You can use this tool to discover hosts and services in computer networks or scan vulnerabilities and ports. It is worth noting that Nmap can be used for free on Linux OS or Linux VPS, Windows OS or VPS, and Mac.

Some of the remarkable features of this tool are the ability to scan large networks and detect open ports, operating systems, and other network services. Network vulnerabilities can be weak passwords, misconfigured services, or outdated software.

Note: You can benefit from the features of this great tool on NeuronVM‘s Linux servers.

How to Start Nmap on Kali Linux?

You can use the following command to start and scan your network. This is the basic command:

nmap [Scan Type] [Options] [Targets]

How to Work With Nmap? (Scan Types)

You can use various ways to scan the network using Nmap. We will examine these scan Types for you:

TCP Connect Scan (-sT):

Completes a full TCP connection to each specified port, providing reliable results but easily detectable.

SYN Stealth Scan (-sS):

Initiates a SYN scan by sending SYN packets to target ports, without completing the full connection, making it less detectable.

UDP Scan (-sU):

Scans for open UDP ports, commonly used for services like DNS and DHCP, provide insight into potential vulnerabilities.

ACK Scan (-sA):

Sends ACK packets to target ports to determine firewall rules, useful for understanding network filtering.

FIN Scan (-sF):

Sends FIN packets to target ports, aiming to identify open ports by observing how they respond to unexpected connection termination requests.

Xmas Tree Scan (-sX):

Sets the FIN, PSH, and URG flags in the TCP header, used to identify firewall behavior based on how it handles unusual flag combinations.

Null Scan (-sN):

Sends null packets (with no TCP flags set) to target ports, useful for identifying firewall configurations.

Idle Scan (-sI):

Utilizes an idle system as a “zombie host” to perform scans more discreetly and reduce the chance of detection.

Version Detection (-sV):

Attempts to determine service and version information on open ports, providing details about the software running on the target.

OS Fingerprinting (-O):

Tries to identify the operating system of the target by analyzing subtle differences in how the system responds to certain packets.

Nmap Scan Options

In this section, we will mention a number of Nmap options that can use to customize the scan. These options are:

-p: To determine which ports to scan.

-sV: To identify the version of services running on the target host.

-o: To specify running operating system on the target host.

-v: Used to increase the verbosity of output on Nmap.

Some Examples of Nmap Usage on Kali Linux

These are some examples to show the way of scanning via Nmap:

• For Ping Scan

the command below will scan the 192.168.1.0/24 network and give the list of online and responsive hosts:

nmap -sP 192.168.1.0/24

• For UPD Scan

This command can use for scanning target host for example (192.168.1.1) and give the list of UPD services on open ports:

nmap -sU 192.168.1.1

• For Custom Port Scan

You can use this one for scanning port 80 on the target host 192.168.1.1 and informing you whether the port is open or closed:

nmap -p 80 192.168.1.1

Some Advance Options Of Nmap on Kali Linux

In addition to these basic functional features, Nmap offers advanced tools and scripts that can be used to perform more comprehensive scans. Here we will mention some of them:

Ability to scan scripts

There is a large library of scripts available in Nmap that you can use to identify potential vulnerabilities on a target host. These scripts can use in combination with other types of scans to perform a comprehensive security analysis of a network.

The Possibility of Stealth Scanning

You can use Nmap for stealth scans. This is designed to prevent detection by firewalls or intrusion detection systems. Techniques like fragmented packet scanning or idle scanning are used here.

Operating System Fingerprint

Using this option will help you detect operating systems running on a target host by analyzing responses to different packets sent to the device.

Conclusion

These are some commonly used Nmap scan types, options, and advanced features each serving different purposes in network reconnaissance. Now, having a better understanding of Nmap and learning how to use it, you can ensure its security by monitoring your network. Always ensure you have permission before scanning any network.

Kali Linux is a Debian distribution operating system that comes with many installed tools. This operating system is provided to help with security checks and penetration testing. In this post, we decided to introduce a powerful password-generation tool in Kali Linux (Crunch).

What is Kali Linux?

When we use the word Linux, we mean the entire Linux operating system. All Linux operating systems have different distributions, each of which has its name and is privately distributed and supported by a company. One of the types of Linux distribution is Kali Linux.

Kali Linux is a security version of the Linux operating system that is mostly designed for security penetration testing. With the variety of plugins and security applications that come with it, this operating system makes it a suitable tool for penetration testing, reverse engineering, and security research.

Kali Linux is actually a unique operating system that is using by everyone, both good and bad. It can be used to discover and fix security vulnerabilities. One of the applications of Kali Linux is hacking with Kali Linux and penetration testing with Kali Linux, which both security experts and hackers do. In other words, Kali is like a sharp knife in the toolbox.

What is Crunch and how does it work?

The crunch tool is a tool in the field of creating a password list and is one of the most powerful in this field. In other words, the Crunch tool is a word list generator where you can use a standard or any character set to generate word lists. Word lists are creating by combining and permuting a set of characters. You can select the number of characters and the size of the list.

This program supports numbers and symbols, uppercase and lowercase letters separately, and Unicode. Among the important features of this tool, the following capabilities can be mentioned:

• The possibility of generating a password list with 2 different combinations and replacement methods
• Support letters, numbers, symbols
• Ability to combine letters, numbers, symbols
• Ability to be case-sensitive
• The ability to stop and resume the password list creation process

How to install Crunch in Kali Linux

Before starting the installation, we recommend that you use the Linux VPS server plans provided on our website and benefit from the high quality and speed of these servers. After getting familiar with Crunch and its capabilities in the previous sections, now it’s time to learn how to install it. Installing Crunch on Kali Linux is very easy, just run the following command:

sudo apt install crunch

This will download and install the crunch package from the official Kali Linux repository. You may need to enter your password and confirm the installation.

To check if Crunch is installed correctly, you can run the following command:

crunch -h

This will display the help page of Crunch, which shows the usage, syntax, and options of the tool. You can also see some examples of how to use Crunch to generate wordlists.

Generating passwords with Crunch

After installing Crunch, at this stage, we want to teach you how to generate passwords with Crunch. To do this, you must follow the steps below.

To create a word list of specific numbers, you can run the following command. Note that this command produces a list of 110 one- and two-digit number words with all combinations of the numbers 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. It is interesting to know that you can use the alphabet.

crunch 1 2 0123456789

Now you can save the created word list in a file by running the following command. The command you see creates a list, and then it copies the same into a text file called wordlist.txt:

crunch 1 2 0123456789 >wordlist.txt

Now you can use the following command to save the list of words in a file with the -o option:

crunch 1 2 0123456789 -o wordlist.txt

Another way to create a password list is to use the rainbow charset file that you can see below:

crunch 2 3 -f /user/share/rainbowcrack/charset.txt

You can use the pattern to create a list of words. In the following command, you can use 4 characters, @ % and ^:

crunch 10 10 -t manav^%%%%

,: used for all capital letters.

@: Used for all lowercase letters.

%: Used for all numeric characters.

^: Used for all special characters.

Finally, to create a list of words by changing strings or characters, you can use the following command:

crunch 1 10 -p Hello Manav

Tips for creating strong and secure passwords

As you read in this article, Crunch is a password-generation tool in Kali Linux. But it is interesting to know some tips about generating strong passwords. A good and secure password is one that cannot be guessed and is not exposed by the methods used by hackers. Hackers use Kali Linux OS to find your password by combining numbers, letters, and symbols. They can easily find short passwords in seconds.

As such, strong passwords consist of a combination of upper and lower case letters, numbers, and special symbols such as punctuation. A good password should be at least 12 characters long, although we recommend using a longer password. In general, the following are the necessary parameters for a good and secure password:

1) A good password has at least 12 characters; The longer your password is, the better.

2) It has uppercase and lowercase letters, numbers, and symbols; A password that is a combination of these is harder for hackers to find.

3) It’s not made of a memorable keyboard track.

4) It is not made according to your personal information.

5) It is unique and different for each account.

Every year, breaches of users’ information and privacy cause huge financial and credit losses to organizations, half of which are caused by cyber-attacks. By conducting a penetration test, companies can prevent data breaches caused by cyber-attacks. Because penetration testing projects include attack simulation along with other techniques. Penetration testing allows businesses to identify vulnerabilities in their IT infrastructure. In the rest of this article, we will tell you how to become a Metasploit Expert on Kali Linux.

Understanding the basics of penetration testing

Penetration testing, also known as Pen Test, is one of the most common and standard methods of security and penetration testing of web applications. Pen Test runs simulated attacks on the website from inside and outside to find out which parts of our website have security weaknesses. It is recommended that all websites in the world use Pen Test so that they can find out the security weakness of their site before hackers and correct it quickly.

The main issue here is that many web applications request sensitive user data and store it in their database. This makes web applications a mine of valuable information. Therefore, hackers have shown great interest in databases. The situation becomes dire when we consider the generality of web applications!

By performing pen test, we pursue the following goals:

• Detecting system vulnerabilities that were previously unknown
• Checking the effectiveness of the current website security rules
• Testing active security components on a site such as a firewall and DNS
• Identifying the weakest parts of the program
• Identifying the appropriate parts of the site for data leakage

Getting started with Kali Linux

Kali Linux is a security distribution of Linux derived from Debian and used specifically for computer crime prevention and advanced penetration testing. This version was developed through the BackTrack rewrite by Mati Aharoni and Devon Kearns of Offensive Security.

Kali Linux includes several hundred tools that have been assembled to perform various tasks in the field of information security, such as penetration testing, security research, computer crimes, and reverse engineering.

Kali Linux has more than 600 penetration testing applications installed on it, each of which you need to discover. Each program has its own flexibilities and uses. Kali Linux has done a great job of separating these useful tools into the following categories:

• Information gathering
• Vulnerability analysis
• Wireless attacks
• Web applications
• Exploit tools
• stress test
• Criminological tools
• wiretapping and forgery
• Password attacks
• Maintenance accesses
• Reverse Engineering
• Reporting tools
• Hardware hacking

In the rest of this article, we will teach how to install and set up Metasploit on Kali Linux.

Installing and setting up Metasploit on Kali Linux

Before starting the installation and configuration process, we recommend you use the Linux VPS server plans provided on our website. In this section, we want to teach you how to install and run Metasploit. To do this, simply run the following command in the Kali terminal:

sudo apt install metasploit-framework

One thing to note is that the Metasploit Service Framework requires the PostgreSQL database service to run. Therefore, you can activate the PostgreSQL service using the following command:

sudo systemctl enable --now postgresql

Now you can start PostgreSQL by running the following command:

sudo /etc/init.d/postgresql start

Confirm PostgreSQL using the following command:

systemctl status postgresql@*-main.service

or

sudo /etc/init.d/postgresql status

Considering that PostgreSQL’s default port is 5432, it is necessary to confirm that the service is active:

sudo ss -ant | grep 5432

In the next step, it is necessary to enter the Rapid7 signature key with the following command:

curl https://raw.githubusercontent.com/rapid7/metasploit-omnibus/master/config/templates/metasploit-framework-wrappers/msfupdate.erb> msfinstall && chmod 755 && msfinstall && ./msfinstall

Start the Metasploit PostgreSQL database by running the following command:

sudo msfdb init

or

sudo msfdb run
sudo msfdb init && msfconsole

You can now configure the Metasploit Framework Service and launch the Metasploit Service Framework (msf) console on your system. Therefore, in the first step, you need to check the database connection:

sudo msfconsole -q

msf5 > db_status

Metasploit modules and functionalities

Metasploit modules are the main components of the Metasploit framework. A module is a piece of software that can perform a specific action such as scanning or exploiting. Every task you can do with Metasploit is defined in a module.

There are four main types of Metasploit modules:

1) Exploit modules: These modules execute code on a target using a vulnerability. Exploit modules can be used to gain access, elevate privileges, or execute commands on a target system.

2) Auxiliary modules: These modules perform various support tasks such as scanning, fingerprinting, sniffing, or brute-forcing. Auxiliary modules can be used to gather information, test for vulnerabilities, or launch denial-of-service attacks.

3) Payload modules: These modules define the code that is executed on a target after a successful exploit. Payload modules can be used to create a shell, execute commands, upload or download files, or create processes on a target system.

4) Post-exploitation modules: These modules are executed after the successful implementation of the exploit and payload. Post-exploitation modules can be used to maintain access, collect data, rotate to other targets, or cover routes to a target system.

To use Metasploit modules you must search for them using the search command and appropriate search operators such as name, platform, type, program, author, etc. You can also use the show command to view a list of all available modules of a specific type.

For example, to search for an exploit module for Windows that has the name “ms08-067”, you can use the following command:

search name:ms08-067 platform:Windows type:exploit

To view all the payload modules, you can use the following command:

show payloads

Exploitation techniques using Metasploit

Exploitation techniques using Metasploit are the methods and steps that you can use to exploit vulnerabilities in systems or applications with the help of Metasploit modules and tools.

These are some of the exploitation techniques using Metasploit that you can use to test or compromise systems or applications:

1) Automated exploitation: Metasploit Pro can build an attack plan based on the service, operating system, and vulnerability information it has for the target system and use it to execute an automated exploit. An attack plan defines the exploit modules that Metasploit Pro will use to attack target systems. To run an automated exploit, you need to specify the hosts you want to exploit and the minimum reliability settings that Metasploit Pro should use.

2) Autopwn: Autopwn is a tool that can be used to automatically execute all exploits against open ports of a target system. This is a feature of Metasploit Express and Metasploit Pro, but can also be used with the Metasploit framework using the db_autopwn command. Autopwn requires a database to store scan results and exploit options.

3) AutoSploit: AutoSploit is a Python-based tool that uses Shodan and Metasploit modules to automate mass exploitation of remote hosts. This allows you to search for targets based on keywords or filters in Shodan and then launch Metasploit exploits against them. You can also customize exploit options and load-outs or use random ones. Scan and/or exploit results appear in the Metasploit console and in the output file(s).

4) Manual Exploitation: Manual Exploitation is the process of selecting and configuring an Exploit Module according to the target system or application, setting required options such as RHOSTS, RPORT, LHOST, LPORT, etc. Manual exploitation gives you more control and flexibility over the exploitation process, but it also requires more knowledge and skill.

Post-exploitation and gaining control

Post-exploitation and gaining control are the processes of performing actions on a target system or network after successful exploitation. It can include collecting information, maintaining access, escalating privileges, pivoting to other targets, or covering tracks. Gaining control can involve creating shells, executing commands, uploading or downloading files, or spawning processes on a target system.

Some of the tools and techniques you can use to post-exploit and gain control include:

1) Meterpreter: Meterpreter is a powerful payload that runs in memory and provides an interactive shell for the target system. It supports various commands and modules that can perform post-exploitation tasks, such as collecting system information, removing passwords, taking screenshots, recording keystrokes, migrating processes, etc.

2) Post-Exploitation Modules: Metasploit has a class of modules called post-exploitation modules that are executed after the successful execution of the exploit and payload. These modules can perform various actions on the target system or network, such as collecting data, maintaining access, routing to other targets, or masking routes. For example, the post/windows/gather/hashdump module dumps password hashes from the SAM database on a Windows system.

3) C2 frameworks: C2 frameworks are tools that allow you to remotely control vulnerable machines through a command and control (C&C) infrastructure. C2 frameworks can help you manage multiple sessions, execute commands, transfer files, or perform further attacks on the target network. Some popular C2 frameworks include Cobalt Strike, Covenant, Empire, etc.

4) Privilege escalation techniques: Privilege escalation is the process of obtaining higher privileges or access rights on a target system or network. The increase in score can be vertical (from a lower score to a higher score) or horizontal (from one user account to another with the same score level). Elevation can be achieved by exploiting vulnerabilities in the system or application, misconfiguration, weak passwords, etc.

Advanced Metasploit techniques and tools

Advanced Metasploit techniques and tools are methods and features that you can use to perform more complex and sophisticated penetration testing tasks with Metasploit. Some advanced Metasploit techniques and tools include:

1) Database Support: Metasploit can integrate with a database to store and manage scan results, hosts, services, vulnerabilities, credentials, loot, etc. It can help you organize and analyze data and share it with other users or tools. Metasploit supports PostgreSQL, MySQL, and SQLite databases.

2) Evading anti-virus: Metasploit can help you evade antivirus detection by using various techniques such as encoding, encryption, obfuscation, or polymorphism. You can use the msfvenom tool to generate payloads with different codecs or formats or use escape modules to create executables that can bypass standard antivirus solutions.

3) Exploit ranking: Metasploit assigns a ranking to each exploit module based on its reliability, stability, and side effects. The ranking can help you choose the best exploit for your target system or application. The ranking levels are excellent, great, good, normal, average, low, and manual.

4) Hashes and password cracking: Metasploit can help you collect and crack password hashes from various sources such as Windows SAM database, Linux shadow files, or network protocols.

5) Metasploit plugins: Metasploit plugins are Ruby scripts that extend the functionality of Metasploit by adding new features or commands. You can use the load command to load a plugin or the show plugins command to view the available plugins. Some useful plugins are auto_add_route, sounds, wmap, etc.

6) Payload UUID: Payload UUID is a feature that allows you to track and identify your shipments by assigning an identifier (UUID). This can help you manage loads and multiple meetings more easily and also avoid conflicts or collisions. You can use msfvenom tool to generate payload with UUID.

Metasploit best practices and ethical considerations

Regarding Metasploit’s best practices, you should know that you need to use a VPS or VPN server or a proxy to hide your real IP address and protect your anonymity. In other words, it is recommended not to expose your identity or location to the target or third parties. The next thing is to watch out for payloads that can cause damage to the target system or network. Do not use payloads that can delete files, corrupt data, or disrupt services unless you have a specific reason and permission to do so.

Keep your Metasploit up to date with the latest exploits and patches. Do not use outdated or unreliable exploits that may fail or cause unintended consequences.

In the following, we will explain some ethical considerations that you should keep in mind when using Metasploit.

Do not harm the target system or network beyond the scope of penetration testing or exploitation. In other words, don’t use Metasploit to harm, disrupt, or steal data or resources. We recommend that you do not violate the laws or regulations of the country or region where you are conducting penetration testing or exploitation. Do not use Metasploit to attack systems or networks protected by law or owned by government, military, or critical infrastructure entities.

One of the most important ethical issues when using Metasploit tools is not to disclose vulnerabilities or exploits you discover or use to anyone who might exploit them. Do not share or sell information or tools you obtain from Metasploit to hackers, criminals, or competitors. Do not impersonate the owner or administrator of the target system or network. We also recommend that you do not use Metasploit to gain unauthorized access to accounts, credentials, or privileges that do not belong to you.

Becoming a certified Metasploit expert

If you want to become a certified Metasploit expert, you have a few options to learn. You must learn how to:

1. Perform network discovery and vulnerability scanning
2. Exploit and validate vulnerabilities
3. Conduct phishing campaigns and test web applications
