Programming languages for Hackers

Earlier we discuss about top operating systems for hackers, today we are here before you to give some information about important programming languages of hackers used for ethical hacking.

Since programming is essential for hacking because a hacker is someone who breaks a protocol or an application security which is programmed in a certain programming language and to hack an application a hacker needs to understand the logic of that app, find flaw and the exploit it. So a hacker must learn a couple of programming languages to complete his task. So checkout the important programming languages for hackers and where to apply it.

Programming Languages of Hackers

There are lots of computer languages but few are required for hacking purpose because in most cases it depends upon target. There are basically three sections ― Web Hacking and Pentesting, Exploit Writing & Reverse Engineering and each of it requires different coding.

Programming languages for Web Hacking and Pentesting

If you’re interested in web hacking and pentesting, then you must learn learn below mentioned languages at-least basic and intermediate level.


Always began with basic basic and HTML is important and most basic markup language. One should know it very well to understand web action, response, structure and logic. HTML is static markup language.

2. JavaScript 

JavaScript : JavaScript is the most used as client-side programming and for web development. You should learn it on high priority mode. Understanding JavaScript code logic can help you find web-apps flaw.

3. SQL

SQL is database programming language. Each and every data is stored in database so you should know about database programming and vulnerability as it is the most sensitive part of Web.

4. PHP

PHP is most popular dynamic programming language, unlike JavaScript It is server-side programming language. PHP is strongly recommended to every beginner in Hacking and Penetration testing.

5. Perl

Perl is worth learning for practical reasons; it’s very widely used for active web pages and system administration, so that even if you never write Perl you should learn to read it.

Programming Languages for writing Exploits

Exploit writing is advance part of Hacking, It requires higher level of programming language. Every professional hacker must know Exploit Writing, It can be done in any programming language like C, C++, Ruby, Python etc.

6. C/C++

The mother of all programming language, C is most used in software creation for Linux, Windows etc. However it is also used for Exploit writing and development. Although  C++ is more powerful language than C and is used in a lot of programs, like games. Here are some basic examples of C programming.

7. Python

Python is most used language for exploit writing, It is highly recommended you to learn Python Socket Programming because it helps lot learning exploit creation.

 8. Ruby

A simple but complicated object-oriented programming language. Ruby is very useful in exploit writing. It is used for meterpreter scripting and do you know Metasploit Framework itself programmed in Ruby.

9. Java

Java was originally released with the slogan “write once, run anywhere,” which was intended to underscore its cross-platform capabilities.You can make tools using Java and it can also be used to create backdoor exploits as well as exploits that can kill a computer.

10. LISP

Lisp is the second-oldest high-level programming language in widespread use today. LISP is absolutely wide open and flexible, makes it hacker’s favourite. You can define your own syntax, and often do. You can create any sort of programming paradigm you like and include it in your programs.

Programming languages for Reverse Engineering

Reverse engineering, also called back engineering, is the processes of extracting knowledge or design information from anything man-made and reproducing it or reproducing anything based on the extracted information. Reverse engineering is also beneficial in crime prevention, where suspected malware is reverse engineered to understand what it does, and how to detect and remove it, and to allow computers and devices to work together. Reverse engineering can also be used to “crack” software and media to remove their copy protection.

11. Assembly Language

Assembly is low level programming language but very complicated. One can instruct a machine hardware or software using Assembly language. Reverse Engineers uses Assembly language, and if you want to learn Reverse Eng, you must need to learn Assembly language.

Finally one more thing, programming languages for hacking also depends upon what program you want to hack, for example; if a web-app in coded in ASP.NET then you can’t hack it using PHP knowledge, although you can understand logic but it will be harder, so always make sure what you wanna hack and in which programming the app is coded.

Also hacking is a skill and only talented well-trained could become a better security expert. So learn these programming languages to its core and hard-train your abilities to solve different coding problems.

So tell us which programming languages do you know and which one are you going to learn soon ? We’d love to hear from you in the comments!


  1. Hi Sabari,

    I’ve seen this post before, but I wasn’t sure Perl, java, lisp were there before! Is this a new post or an edited one.

  2. I am very interested in learning all of these languages. I have used little c++ and some python, but nothing other than basics. Where could I learn all of these programming languages with video and get certified at least with intermediate knowledge? I searched coursera, but all I could find out was introductions, but I want something that can get me on a high level on each Language. Even if it costs a little bit more. something legit. I await for your answer, thanks in advance!

    • One way you could start without using money is in codeacademy, then another step you could take after that is looking up examples of code off the internet or even from youtube.

    • The priority is according to what type of programming language you wanna learn
      Be it web….exploits…or reverse engineering
      For web js and sql are of greatest priority
      Php and perl are too but that will depend on the backend language of the app
      But 80% of worlds web apps are built with php….So u get the pic bro 🙂
