The word ‘Hacking’ originally refers to an activity that requires great skill and knowledge of computer systems. Unfortunately, these skills are applied in illegal activities like breaking passwords, releasing viruses to corrupt the computer systems, or stealing valuable data and information. In fact, it is a technique by which some computer experts can access the data from confident areas of the system. Many of these activities require a certain amount of skill and knowledge and hence and hence, are often done by intelligent professionals.

The people who are involved in these crimes are called hackers. A large number of hackers run publicly available programs that automate attempts to break into systems. Hackers also merge wrong information, viruses, or corrupt data in the users’ data and thus, corrupt the computer systems.

Reasons for hacking

  • Theft of services: It may be taken as a challenge to avail of the services provided by the system without being acknowledged.
  • To take valuable files: Sometimes, people tend to steal secret information and promote computer terrorism.
  • Thrill and excitement: People think that it is exciting to be a part of the world of computer crimes.
  • Disease: Some people are physiologically disturbed and want to apply their intelligence in anti-social activities. They are unable to judge the consequences of their immoral activities.
  • For knowledge and experiment: Sometimes, people want to make destructive work as a tool for gaining knowledge and doing experiments

Malicious code

Malicious code refers to a new kind of threat, which cannot be blocked by using antivirus software, and which corrupts the system in due course of time. However, by the time, it is noticed, it is too late. Usually, the victim is ignorant of a malicious attack, making it virtually impossible to recognize.

Malicious code is any program that acts in unexpected and potentially that acts in unexpected and potentially damaging ways. It can attack the institutions at either the server or the client level. They can be of different forms:

  • While working on e-mails
  • At the time of web surfing

Hacking has been one of the most used words in the world of computing. Hacking has provided jobs to many people but has also proved to be dangerous to many innocent people. Many programmers want to have a carrier as a professional ethical hacker but always come across these questions How to become a hacker? What qualifications are needed? Is it legal?

Need for a hacker

It is completely essential for a company because every company receives a lot of intrusions from local hackers who are illegally trying to steal data, money, etc. from a company to fulfill personal needs and obtain maximum benefit without working under someone.

Basics of hacking

Hacking can be done by softwares such as ‘Kali Linux’, ‘Wireshark’, and ‘Jack the Ripper’ are softwares that have provided various hacking platforms to multiple hackers across the world. To start a carrier as a hacker Kali Linux in my view is the easiest and most modern software for hacking. To hack into a computer the minimum hardware requirements are fast RAM, a computer that is compatible with the software, large storage, and a well-working CPU. It would be great if a gaming PC is used because as you enter hack into a system and try to access its files, a computer with less RAM and slow CPU may get exhausted easily

Legality of hacking

Hacking is divided into Legal and Illegal hacking.

Legal Hacking is divided into White Hat hacking And Grey Hat Hacking whereas Illegal Hacking is divided into Black Hat Hacking.

To become a White Hat Hacker one has to either complete an online course of hacking or can obtain a degree from any college.

Cyber criminals can be divided into various groups. This division may be justified based on the objective that they have in their minds. The categories are:

  • Organized Hackers: Organized hackers refers to those who are organized together to fulfill certain objective such as their political bias, fundamentalism, etc.
  • Professional Hackers: Professional hackers are mostly employed by business organizations to hack the websites of their rivals and get credible, reliable, and valuable information.
  • Discontent Employees: These groups include those people who have either been sacked by their employers or are dissatisfied with their employers. Thus, they tend to interrupt the normal work of their employees by hacking their websites.

Prevention of cyber crime

  • Use Strong Passwords:
    Use different user ID/password combinations for different accounts and avoid writing them down. Make the passwords more complicated by combining letters, numbers, special characters (minimum of 10 characters in total), and change them regularly.
  • Secure your computer:
    • Activate your firewall:
      Firewalls are the first line of cyber defense; they block connections to unknown or bogus sites and will keep out some types of viruses and hackers.
    • Use anti-virus/malware software:
      Prevent viruses from infecting your computer by installing and regularly updating anti-virus software.
    • Block spyware attacks:
      Prevent spyware from infiltrating your computer by installing and updating anti-spyware software.
  • Be Social-Media Savvy:
    Make sure your social networking profiles (e.g. Facebook, Twitter, Youtube, MSN, etc.) are set to private. Check your security settings. Be careful about what information you post online.  Once it is on the Internet, it is there forever!
  • Secure your Mobile Devices:
    Be aware that your mobile device is vulnerable to viruses and hackers.  Download applications from trusted sources.
  • Install the latest operating system updates:
    Keep your applications and operating system (e.g. Windows, Mac, Linux) current with the latest system updates. Turn on automatic updates to prevent potential attacks on older software.
  • Protect your Data:
    Use encryption for your most sensitive files such as tax returns or financial records, make regular back-ups of all your important data and store it in another location.
  • Secure your wireless network:
    Wi-Fi (wireless) networks at home are vulnerable to intrusion if they are not properly secured. Review and modify default settings. Public Wi-Fi, a.k.a. “Hot Spots”, are also vulnerable. Avoid conducting financial or corporate transactions on these networks.
  • Protect your e-identity:
    Be cautious when giving out personal information such as your name, address, phone number, or financial information on the Internet. Make sure that websites are secure (e.g. when making online purchases) or that you’ve enabled privacy settings (e.g. when accessing/using social networking sites).
  • Avoid being scammed:
    Always think before you click on a link or file of unknown origin. Don’t feel pressured by any emails. Check the source of the message. When in doubt, verify the source. Never reply to emails that ask you to verify your information or confirm your user ID or password.  
  • Call the right person for help:
    Don’t panic! If you are a victim, if you encounter illegal Internet content (e.g. child exploitation) or if you suspect a computer crime, identity theft, or a commercial scam, report this to your local police. If you need help with maintenance or software installation on your computer, consult with your service provider or a certified computer technician.
