Structured Query Language or SQL attacks are a piece of cake for hackers. It deceives the host system and provides the information to the hacker.

Command made by SQL has a strong impact. It is a handy tool for entering and gathering information from corporate databases. Complex SQL code sequences are usually typed in search boxes, login boxes, or 'sign up' fields. This helps in the extraction of the necessary information that was hidden behind the barriers.

Web apps built on SQL Server, Oracle, and MySQL are more vulnerable to SQL injection attacks. High sensitive data exposure makes SQL the best programming language for ethical hacking.

On the basis of SQL injection, black hat hackers create and operate highly functioning hacking programs.

4. Java

There is no doubt that JavaScript is one of the most important program languages for hacking. Since it is equipped with full-stack—both front-end and back-end web—technologies, it can enter and alter complex systems too. In addition, its WORA functionality aids in flexibly hacking web or mobile apps and servers.

Although Java is easy to track, which is used as an advantage by professionals, sound knowledge of this language is a must. It is a general-purpose language with robust and reliable codes.

Data suggests that 95% of enterprise desktops run Java, and 88% of all computers in the U.S. work on Java, including personal machines. This makes it important to learn the language and master it.

You can use it to make internet worms as it can smoothly manipulate browser DOM. It allows hackers to create mimicking attacks on both the server and client-side of the system.

5. C

When targeting low-level components like RAM, C is the go-to language. It is a middle-level procedural programming language with low-level nature that digs into the security systems protecting resources and hardware. It is also used in the creation of lightning-fast socket programming scripts.

C language simulates the library hijacking attack enabling a successful attack by the ethical hacker. C programming is the basis for learning UNIX/LINUX platforms. It is a general-purpose language which makes up many other systems and promises easy access with minimum runtime support.

Not only can it access hardware data but also create shellcodes. Its speed is the biggest strength. It serves the purpose of ethical hacking. People find C on the traditional side of the tech spectrum in place of modern.

Many modern systems like Windows and Unix are built on C programs. Therefore, understanding C language makes it completely easy for you to access and evaluate the faults in the system.

6. Perl

Perl

Wikipedia defines Perl as a "family of two high-level, general-purpose, interpreted, dynamic programming languages." This definition is enough to understand its importance in the ethical hacking world.

Perl was originally designed for text manipulation but now has multiple benefits. Its dynamic approach enables exploit-writing. It assists in manipulating Linux text files and creating tools and exploits. Tools like Nikto, snmpenum, onesixtyone, and fierce are created using Perl.

Perl helps in sending SQL scripts from a web application to a back-end database. This ability of Perl is also exploited by the Amazon website. It is one of the easiest program languages for hacking. Therefore, it attracts many beginners.

Despite the decrease in its popularity on a general level, Perl still rules over several platforms. Polyglot hackers are known to use Perl for building different components of successful hacking programs. This process includes everything from creating exploits to the development of payloads and backdoors. 

7. Ruby

Ruby is a high-level, general-purpose programming language that supports multiple paradigms. It is an excellent program language for hacking as it can write quick scripts on a Linux platform. In addition, it is a web-oriented language and is the most important language used for writing effective exploits.

This scripting language takes help from many syntactical elements — Smalltalk. It is an excellent option for writing fast hacking programs and is used for writing CGI scripts. Its flexibility makes it popular among the biggest companies and the experts of hackers!

Metasploit is the most infamous penetration testing framework that chose Ruby as its base language. It has similarities with Python and borrows the syntactical elements from Smalltalk. This offers versatility and helps in targeting next-generation web platforms too.

8. Bash

Bash

It is not considered a full-blown program language for hacking, but it is extremely important to have proficiency in Bash language. It is an open-source GNU project and the default command shell in most Unix systems.

Bash is a command-line interpreter, or you can call it a user shell to interpret user commands which delivers the output in the form of characters. It comes in handy while manipulating the system. For example, when you are trying to penetrate a network, Bash will provide automated support. No other programming language can fight it by modifying the filesystem and directory tree.

Armitage, NMAP, and Metasploit are the ethical hacking tools that require a sound knowledge of Bash. It can even outperform Python when it comes to processing startup time. It gives you a way into complex and complicated systems with strong security. Once you have established the access, Bash takes over and facilitates the process for you.
