which is :

WHAT IS CYBERCRIME ?

Crime committed using a computer and the internet to steal a person’s identity or illegal imports or malicious programs

Cont’d

First spam email took place in 1978 when it was sent over the Arpanet

The first virus was installed on an Apple computer in 1982

TYPES OF CYBERCRIMES Hacking Child Pornography Denial of Service(DoS) Virus Dissemination Computer Vandalism Cyber Terrorism Software Piracy

HACKING Illegal intrusion into a computer system

and/or network Hackers writes or use ready-made computer

programs to attack the target computer Includes breaking into a computer with

intention to steal, damage, modify or monitor data or settings within a system

CHILD PORNOGRAPHY The internet is being highly used by its

network or fills his e-mail box with spam mail depriving him of the services he is entitled to access or provide

VIRUS DISSEMINITION Malicious software that attaches itself to

other software Circulate themselves to other files and to

other computers on a network Affect the data on a computer, either by

altering or deleting it

COMPUTER VANDALISM An act of damaging or destroying data rather

than stealing or misusing them

CYBER TERRORISM It is the actual use of computers and internet

technology to cause intimidation and destruction

STATISTICS(cont..)

CASE STUDY 1CYBER CRIMINALS TARGET SKYPE, FACEBOOK & WINDOWS USER

CASE STUDY 1

Cyber criminals target social network & Windows users with Blackhole malware.

Disuised as Windows licences, Facebook account verification, Skype voicemail notifications & spam messages.

Biggest dangers Internet users face.

Users who click the malicious Blackhole links & downloaded the files were infected with a Trojan virus.

Spam email campaign targeted Facebook users with a message claiming that their account was locked and needed to be re-verified.

The links led to Blackhole exploits and a Zeus Trojan disguised as an Adobe Flash Player download.

Users should verify the source and destination of any link before clicking

they should never run executable files unless they are positive that the source is legitimate

CASE STUDY 2HACKING OF US DRONE TECHNOLOGY

CASE STUDY 2 Chinese hackers increasingly attracted to

US drone technology Hacker group “Comment Crew” hacked US

military network stealing classified information of US military drones.

They targeted both large companies, including US military contractors & military firms focused on drone technology.

Chinese drone identical to US Predator drone.

US drone market could be the first victim of Chinese espionage.

PREVENTION

Antivirus & Anti Spyware software Firewalls Cryptography Cyber Law & Ethics

Antivirus & Anti Spyware software

to identify and eliminate computer viruses and other malicious software.

to restrict backdoor program, trojans

and other spywares to be installed on the computer.

Firewalls protects a computer network from

unauthorized access. guards an internal computer network

against malicious access from outside the network.

Cryptography

science of encrypting and decrypting information.

Encryption is like sending a postal mail to another party with a lock code on the envelope which is known only to the sender & the recipient.

A number of cryptographic methods have been developed and some of them are still not cracked.

Cyber Laws & Ethics

Responsibility of every individual to follow cyber ethics and cyber laws.

ISP should provide high level security at their severs

Security software as a protection Essential features in the cyber world

today.

CONCLUSION Cybercrimes increase with the rapidly

growing internet technology. It is not possible to eliminate

cybercrimes. It is quite possible to

check them. Awareness is always the

first step to protect yourself.
