Background: One of the perils of an increasingly digital business environment is the rise of cyber crimes. Advocate Madhur Vinod Kumar shares a detailed list of cyber threats. Read on to understand how to better safeguard your business.

We are in the digital era. The use of computers, software and digital information are intrinsic to our day to day life. Many transactions and businesses nowadays take place in the cyber realm. It has a wide scope and its purview increases with time. This calls for certain cyber laws in place to prevent mishaps.

Computer crime or an e-crime can be simply defined as a crime where a computer is the target of a crime or it is the means adopted to commit a crime. While some of the crimes may be new, the others are simply different ways to commit conventional crimes such as frauds, theft, blackmailing, forgery, and embezzlement, using the online medium often involving the use of the internet. What accelerates the growth of such crimes are typical characteristics of cyberspace interalia anonymity, speed, access, dependency, borderless space.

We are in the digital era. The use of computers, software and digital information are intrinsic to our day to day life. This calls for certain cyber laws in place to prevent mishaps.


Cyber crimes include virus attacks, salami attacks, e-mail bombing, DOS attacks, internet hacking or information offenses.

The nature and dimension of information technology leads to peculiar legal problems. The problem deserves special treatment, because of the environment in which they creep up, the nature of the machinery used, and the means employed for recording the information in question is atypical.

In all the other cases the documents are stored and transmitted through the use of visible and tangible letters, figures and marks. However, here the information which is stored and transmitted electronically has no visible shape or tangible form, and this peculiarity of the technology gives rise to a different kind of legal problems. Therefore, to overcome this legal problem the Information Technology Act, 2000 came into force in India on 17 October 2000. The Act applies to all of India. Sometimes it applies to outside India also by any person irrespective of his nationality, if such act involves a computer, computer system or network located in India.

The meaning of computer
As per information technology Act ‘computer’ means any electronic, magnetic, optical or other high-speed data processing device or system which performs logical, arithmetic and memory functions by manipulations of electronic, magnetic or optical impulses, and includes all input, output, processing, storage, computer software, or communication facilities which are connected or related to the computer in a computer system or computer network.

Two categories of cyber crimes 

  • The Computer as a Target: Using a computer to attack other computers. e.g. Hacking, Virus/Worm attacks, DOS attack, etc.
  • Using the computer as a weapon: Using a computer to commit real-world crimes. e.g. Cyber Terrorism, IPR violations, Credit card frauds, EFT frauds, Restricted videos, etc.


Modes of cyber crimes

Unauthorised access and hacking

Access means gaining entry into, instructing or communicating with the logical, arithmetical, or memory function resources of a computer, computer system or computer network.  Unauthorised access means any kind of access without the permission of either the rightful owner or the person in charge of a computer, computer system or computer network. Every act committed to breaking into a computer and/or network is hacking. Hackers write or use ready-made computer programmes to attack the target computer. They possess the desire to destruct and they get the kick out of such destruction. Some hackers hack for personal monetary gains, such as to steal the credit card information, transfer money from various bank accounts to their own account, etc.

Web hijacking is also a crime which means taking control of other websites.

Virus and Worm attack

A programme that has the capability to infect other programmes and make copies of itself and spread into other programmes is called a virus.

Programmes that multiply like viruses but spread from computer to computer are called worms.

E-mail & IRC related crimes

  • Email spoofing

An email shown to have sent from one source, in fact, has been sent from a different source is called spoofing.

  • Email Spamming

Sending email to thousands and thousands of users, similar to a chain letter, is called email spamming.

  • Sending malicious codes through email

Emails are used to send viruses, Trojans, etc through emails as an attachment or by sending a link of the website which on visiting downloads malicious code.

  • Email bombing

Abusive identical messages sent repeatedly to a particular address is called emails bombing.

This includes:

  • Sending threatening emails
  • Defamatory emails

Denial of service attacks

Flooding a computer resource with more requests than it can handle. This causes the resource to crash thereby denying access of service to authorised users. Attempts to ‘flood’ a network, thereby preventing legitimate network traffic, attempts to disrupt connections between two machines, thereby preventing access to a service, attempts to prevent a particular individual from accessing a service and attempts to disrupt service to a specific system or person are examples of Daniel Service Attacks.

Distributed DOS

A distributed denial of service (DoS) attack is accomplished by using the Internet to break into computers and using them to attack a network. Hundreds or thousands of computer systems across the Internet can be turned into ‘zombies’ and used to attack another system or website.

Types of DOS

There are three basic types of attack:

  • Consumption of scarce, limited, or non-renewable resources like NW bandwidth, RAM, CPU time. Even power, cool air, or water can affect.
  • Destruction or Alteration of Configuration Information
  • Physical Destruction or Alteration of Network Components

Theft of internet hours

Unauthorised use of internet hours paid for by another person.

By gaining access to an organisation's telephone switchboard (PBX) individuals or criminal organisations can obtain access to dial-in/dial-out circuits and then make their own calls or sell call time to third parties. Additional forms of service theft include capturing 'calling card' details and on-selling calls charged to the calling card account and counterfeiting or illicit reprogramming of stored value telephone cards.
