Everyone who works on a computer must be familiar with the term “Cyber Crime.” Initially, when the computer was invented and the technology for communicating between computers evolved, no one ever thought that the cyberspace could be flooded with any crime; i.e. cybercrime. But now, almost all of us have heard the term computer crime, cyber-crime, hi-tech crime, or electronic crime which is nothing but an act done by a criminal who has bad intentions, where a computer or maybe a network is a source, tool, target, or place of a crime. To say it in one sentence, “Cyber-crime refers to all the activities done with criminal intent in cyberspace.”

What we need to know about Cyber Crime

Most of us are using the internet and computers for online transactions where we transmit personal information and possibly do monetary transactions. If your personal information gets into the wrong hands and you become bankrupt, or you start receiving absurd emails, or your e-mail account gets flooded with unwanted mails; that indicates that you have become a victim of cyber crime.

The hacker’s main aim is to disrupt a system or network. Whether he is a white-hat hacker or a black-hat hacker, this level of destruction is to stop or get  access to the computer systems. Repeated hacking or tampering constantly might put a hacker behind bars but most of the time, these crimes are taken lightly.

What is Hacking?

Hacking is the practice of making malicious modifications to a program in order to achieve a goal outside the original purpose of the creator. A person who engages in these activities is called hacker, an expert in programming who regards hacking as a part of the way to apply the skills, like stealing personal information, and gaining unauthorized access.

It doesn’t always have to be someone you don’t know who hacks into your systems and causes problems for your business. It could actually be someone who works for you that doesn’t have your best interest at heart. This is because the basic meaning of hacking is when someone accesses some or all the information of your computer system without permission, and it doesn’t just happen over the internet.

Quite often, many people don’t see how widespread computer hacking can be. Assuming that they are only in danger from internet-based attacks means they may not be covered for all risks. Even those companies that do all they can to prevent hacking which occurs online may have unwittingly turned a blind eye to other dangers.

This is why an understanding of what hacking is and what it involves can help you to protect your own business more fully. But what do you do  if you don’t know all the ins and outs of the threats posed? The easy solution is to rely on an expert to make sure that every potential hole is plugged, and no one can break into your systems. Network penetration testing is one of the best ways to see how good your computer network really is. If you assume everything is okay and it isn’t you could be in for a nasty shock at some point in the future.

An expert in the field of ethical hacking would be able to highlight any potential problems and solve them before anyone else had a chance to exploit them, and that is certainly a service that is worth paying for. Don’t make the mistake of thinking this should be the done once though. Hackers are constantly finding a new way into previously secure systems. If you employ a company to see how to update your security measures, make sure you do it on regular basis. If you don’t you still run the risk of being caught out.

Ethical hackers aim to bring into the administration’s notice, vulnerabilities and voids in the system, thereby improving the robustness and security. They are purely tech-geeks with immaculate programming skills and hands-on knowledge on both computer hardware and software. On the other hand, there are people who can break through our systems, get access to secured accounts but their actions are usually unauthorized while they make a backdoor entry into our system. These people are called  ‘Crackers.’ They try to crack passwords and security and codes etc, using many hacking software programs which are already available. Such software is meant to break the code using millions of trials programmed into it by other hackers.

Traditional cyber crimes

Criminals whose focus is on monetary gains only are called traditional cyber criminals. Most of them are identified as some internal source. A recent study has confirmed that almost 80% of offenders of such crimes belong to the related company or frim. Industrial espionage, illegal fund transfers, credit card scams and etc. are some of the traditional cyber crimes. Such criminals who conduct these crimes are more likely to end up behind bars if the crime is proven.

Cyber Threats

Stolen data are circulated against the intellectual property laws according to ideology threats. The hackers spread the data which is preserved under the intellectual property rights. Many terrorist activities are also termed as an ideology or opposition to government by using internet tech. Cyber-anarchistsis as they are called have the primary aim is to disseminate their ideology or principles.

Thus whatever be the nature of the cyber crime strict laws must be administered to enable a secure cyber space. As more and more of our daily activities become connected or interlinked in cyberspace the need for a complete secure technology has become the need of the hour. Whether it is simple email hacking or phishing, the people involved in such activities are definitely invading the privacy of individuals and business organizations. Identify theft, money swindling, and credit card scams are grave issues which can cause irreparable damage to the person concerned.

Types of hacking

Hacking is usually meant to break a code. There are three sections of hacking which are Web hacking, Exploit writing & Reverse engineering and each of them require different programming language.

  1. Web hacking
    Most of the tech is built around world wide web. For example, let’s say that you are interested in hacking web apps and /or websites, then you need to learn web coding. Websites use mostly HTML, PHP, and JavaScript, one of the  easiest and most widely used static mark-up web language present in each and every website you see in your browser. It’s recommended to learn HTML because it helps in understanding web actions, response, and logic

    1. JavaScript
      JS is a client-side web programming mostly used in websites for better user interface and quick response. It helps in understanding Client Side mechanism which is essential for finding Client Side flaws.
    2. PHP
      A dynamic Server-side language which is responsible for managing the web-apps and database. PHP is considered as the one of the most essential languages because of it controls everything on site and server, like a caption on a ship.
  2. Exploit writing
    After web hacking, another part of important feature of hacking is exploits, any particular software can be cracked using exploits, the exploit is a piece of software or a sequence of commands that takes advantage of a bug to cause unintended behavior to occur on computer software, hardware, or something electronic (usually computerized). Such behavior frequently includes things like gaining control of a computer system, allowing a denial of service. For writing the exploits we need to learn python or ruby.

    1. Python
      It is said that a security hacker should know Python because it is the core language for creating exploits and tools. Security experts and even pro hackers will mostly suggest  mastering Python since it offers more flexibility
    2. Ruby
      Ruby is a simple yet complicated object-oriented language; it comes in very handy especially in when it comes to exploiting writing. It is used for meterpreter scripting by hackers. The most famous tool of hacking, known as metasploit, is framed by ruby programming.
  3. Reverse Engineering
    Reverse engineering is a process of taking a software program’s binary code and recreating it so as to trace it back to the original source code. It involves converting code that is written in high-level language into low-level language without changing the original source code, With the help of Reverse Engineering we can modify  software,  like we can change the name of a software, we can edit  software, and we can convert trial software to license software.
