Cyber crime

Hacking
Hacking in simple terms means an illegal intrusion into a computer system and/or network. There is an equivalent term to hacking i.e. cracking, but from Indian Laws perspective there is no difference between the term hacking and cracking. Every act committed towards breaking into a computer and/or network is hacking. Hackers write or use ready-made computer programs 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 stealing the credit card information, transferring money from various bank accounts to their own account followed by withdrawal of money. They extort money from some corporate giant threatening
The lead federal agency for investigating cyber attacks by criminals, overseas adversaries, and terrorists. The threat is incredibly serious—and growing. Cyber intrusions are becoming more commonplace, more dangerous, and more sophisticated. Our nation’s critical infrastructure, including both private and public sector networks, are targeted by adversaries. American companies are targeted for trade secrets and other sensitive corporate data, and universities for their cutting-edge research and development. Citizens are targeted by fraudsters and identity thieves, and children are targeted by online predators. Just as the FBI transformed itself to better address the terrorist threat after the 9/11 attacks, it is undertaking a similar transformation to address the pervasive and evolving cyber threat. This means enhancing the Cyber Division’s investigative capacity to sharpen its focus on intrusions into government and private computer networks.

Computer and Network Intrusions

The collective impact is staggering. Billions of dollars are lost every year repairing systems hit by such attacks. Some take down vital systems, disrupting and sometimes disabling the work of hospitals, banks, and 9-1-1 services around the country.

Who is behind such attacks? It runs the gamut—from computer geeks looking for bragging rights…to businesses trying to gain an upper hand in the marketplace by hacking competitor websites, from rings of criminals wanting to steal your personal information and sell it on black markets…to spies and terrorists looking to rob our nation of vital information or launch cyber strikes.
Computer Viruses
Computer viruses are computer programs that, when opened, put copies of themselves into other computers' hard drives without the users' consent. Creating a computer virus and disseminating it is a cyber crime. The virus may steal disk space, access personal information, ruin data on the computer or send information out to the other computer user's personal contacts.

The most common way for a virus to infect a computer is by way of an email attachment. An example would be if you received an email with an attachment. You open this attachment, and the virus immediately spreads through your computer system. In some cases, if the virus is opened by a computer on a system network, such as your place of employment, the virus can immediately be spread throughout the network without needing to be sent via email.

There are numerous reasons that a person would create a virus to send out to another computer or computers. It may be to steal information or money, to sabotage that system or to demonstrate the flaws that the other computer system has. In some cases these viruses are able to be removed from the user's computer system, and in some cases they are not. Therefore, it is easy for us to understand how these viruses cause significant financial harm every year. The punishment for those who damage or gain unauthorized access to a protected computer can be prison time and the repayment of financial losses.
