8. C#
Like C++, C# (pronounced C Sharp) is a general-purpose, object-oriented language built on the foundations of C. It was originally designed by Microsoft as part of its .NET framework for building Windows applications.

C# uses a syntax that’s similar to other C-derived languages such as C++, so it’s easy to pick up if you’re coming from another language in the C family. C# is not only the go-to for Microsoft app development, but it’s also the language mobile developers use to build cross-platform apps on the Xamarin platform.

Additionally, anyone who is interested in VR development should consider learning C#. C# is the recommended language for building 3D and 2D video games using the popular Unity game engine, which produces one-third of the top games on the market.

9. Rust
Rust is a bit of an upstart among the other languages on this list, but that doesn’t mean it’s not a valuable language to learn. Stack Overflow’s 2020 Developer Survey found that Rust was the most loved programming language among developers for the fifth year in a row, with 86.1 percent of Rust developers saying that they want to continue working with it.

Developed by the Mozilla Corporation, Rust, like C and C++, is intended primarily for low-level systems programming. What Rust adds to the mix, however, is an emphasis on speed and security. Rust emphasizes writing “safe code” by preventing programs from accessing parts of memory that they shouldn’t, which can cause unexpected behavior and system crashes.

The advantages of Rust mean that other big tech companies, such as Dropbox and Coursera, are already starting to use it internally. While it may be a bit more difficult to master than other beginner languages, Rust programming skills are likely to pay off handsomely, as the language's popularity will only continue to rise in the near future.
@cmd_programming
When deciding which programming language to learn, it’s important not to get caught up in flashy trends and popularity contests. The best programming languages to learn in 2021 are likely the same ones that were best to learn in 2017 and 2018, and that will continue to be true for the next several years as well.

Although the field of computer programming changes rapidly, the languages that we’ve discussed above have a great deal of staying power. By learning one or more of these languages, you’ll be in an excellent position not only for this year but in the years to come.

When beginning your journey into coding, only you can answer the question of the best programming language to learn. Make your selection based on your interests and the type of software development you want to get into. Here is a quick summary of the different possibilities that we’ve discussed:

What is the Metasploit Framework and How is it Used?

The Metasploit Project is a computer security project that provides information about security vulnerabilities and aids in penetration testing and IDS signature development. It is owned by Boston, Massachusetts-based security company Rapid7.

The Metasploit framework is a very powerful tool which can be used by cybercriminals as well as ethical hackers to probe systematic vulnerabilities on networks and servers. Because it’s an open-source framework, it can be easily customized and used with most operating systems.

With Metasploit, the pen testing team can use ready-made or custom code and introduce it into a network to probe for weak spots. As another flavor of threat hunting, once flaws are identified and documented, the information can be used to address systemic weaknesses and prioritize solutions.

A Brief History of Metasploit

The Metasploit Project was undertaken in 2003 by H.D. Moore for use as a Perl-based portable network tool, with assistance from core developer Matt Miller. It was fully converted to Ruby by 2007, and the license was acquired by Rapid7 in 2009, where it remains as part of the Boston-based company’s repertoire of IDS signature development and targeted remote exploit, fuzzing, anti-forensic, and evasion tools.

Portions of these other tools reside within the Metasploit framework, which is built into the Kali Linux OS. Rapid7 has also developed two proprietary OpenCore tools, Metasploit Pro, Metasploit Express.

This framework has become the go-to exploit development and mitigation tool. Prior to Metasploit, pen testers had to perform all probes manually by using a variety of tools that may or may not have supported the platform they were testing, writing their own code by hand, and introducing it onto networks manually. Remote testing was virtually unheard of, and that limited a security specialist’s reach to the local area and companies spending a fortune on in-house IT or security consultants.

Who Uses Metasploit?
Due to its wide range of applications and open-source availability, Metasploit is used by everyone from the evolving field of DevSecOps pros to hackers. It’s helpful to anyone who needs an easy to install, reliable tool that gets the job done regardless of which platform or language is used. The software is popular with hackers and widely available, which reinforces the need for security professionals to become familiar with the framework even if they don’t use it.

Metasploit now includes more than 1677 exploits organized over 25 platforms, including Android, PHP, Python, Java, Cisco, and more. The framework also carries nearly 500 payloads, some of which include:

- Command shell payloads that enable users to run scripts or random commands against a host
- Dynamic payloads that allow testers to generate unique payloads to evade antivirus software
- Meterpreter payloads that allow users to commandeer device monitors using VMC and to take over sessions or upload and download files
- Static payloads that enable port forwarding and communications between networks

Metasploit Uses and Benefits
All
you need to use Metasploit once it’s installed is to obtain information about the target either through port scanning, OS fingerprinting or using a vulnerability scanner to find a way into the network. Then, it’s just a simple matter of selecting an exploit and your payload. In this context, an exploit is a means of identifying a weakness in your choice of increasingly harder to defend networks or system and taking advantage of that flaw to gain entry.

The framework is constructed of various models and interfaces, which include msfconsole interactive curses, msfcli to alls msf functions from the terminal/cmd, the Armitag graphical Java tool that’s used to integrate with MSF, and the Metasploit Community Web Interface that supports remote pen testing.

White hat testers trying to locate or learn from black hats and hackers should be aware that they don’t typically roll out an announcement that they’re Metasploiting. This secretive bunch likes to operate through virtual private network tunnels to mask their IP address, and many use a dedicated VPS as well to avoid interruptions that commonly plague many shared hosting providers. These two privacy tools are also a good idea for white hats who intend to step into the world of exploits and pen testing with Metasploit.

As mentioned above, Metasploit provides you with exploits, payloads, auxiliary functions, encoders, listeners, shellcode, post-exploitation code and nops.

You can obtain a Metasploit Pro Specialist Certification online to become a credentialed pen-tester. The passing score to obtain the certification is 80 percent, and the open book exam takes about two hours. It costs $195, and you can print your certificate out once you’re approved.

Prior to the exam, it’s recommended that you take the Metasploit training course and have proficiency or working knowledge:

- Windows and Linux OS
- Network protocols
- Vulnerability management systems
- Basic pen testing concepts
Obtaining this credential is a desirable achievement for anyone who wants to become a marketable pen-tester or security analyst.

Learning How to Use Metasploit: Tutorial + Tips
The ease of learning to use Metasploit depends on your knowledge of Ruby. However, if you have a familiarity with other scripting and programming languages like Python, making the jump to working with Metasploit shouldn’t be too difficult to get up to speed. Otherwise, it’s an intuitive language that’s easy to learn with practice.

Because this tool requires you to disable your own systematic protections and enables the generation of malicious code, you should be aware of the potential risks involved. If possible, keep this utility installed on a separate system than your personal device or any computer that contains potentially sensitive information or access to such information. You should use a dedicated work device when pen-testing with Metasploit.

In this free ethical hacking course, you will learn all about Ethical hacking lessons with loads of live hacking examples to make the subject matter clear. It is recommended you refer these Hacking Tutorials sequentially, one after the other to learn how to be a hacker. This free hacking course for beginners will help you learn all the ethical hacking concepts.

What is Ethical Hacking?

Ethical Hacking is a method of identifying weaknesses in computer systems and computer networks to develop countermeasures that protect the weaknesses. An Ethical hacker must get written permission from the owner of the computer system, protect the privacy of the organization been hacked, transparently report all the identified weaknesses in the computer system to the organization, and inform
hardware and software vendors of the identified weaknesses.
