  • TECHNICAL SIDE OF THE
  • INTERNET COMPUTER
  • CRIME

2
An Introduction to the Net
As of the year 2000, the Internet has become
an international collection of over 9.7 million
computer networks, all very capable of
communicating with one another. Approximately
300 million people world-wide have access to the
Internet (122.6 million of them being in the
United States). So how do each of these
computers connect with one another?
3
How Computers Connect
Every computer that is connected to the Internet
depends on Internet Protocol (IP) to communicate
with one another. Each computer has an IP
Address. An example of an IP Address may look
like 128.172.101.102. The first set of digit(s)
in this example, 128, identifies a section of the
main Internet system. The next set of digit(s),
172, identifies a specific network. The next set
of digit(s), 101, identifies a section or
department of the specific network. Finally, the
last set of digit(s), 102, identifies a specific
computer within that network.

Surfin The Web
Most people who surf the web use browsers, such
as Microsoft Internet Explorer or Netscape
Communicator. These browsers allow your
computer to connect to servers (computers that
store web site files and "serves" them to you
when requested). These communications over the
net are not private. Nearly everything is sent
unencrypted and can be easily read.
6
Information Exchange
When computers connect, certain information can
be exchanged. For instance, some web sites can
log your IP address. Others can place on your
hard drive a "cookie" (a text file that is
stored in the hard drive of your computer,
telling the server things about you,
your computer and your activities). Web browsers
can be customized in their settings to accept or
reject the cookie. Passwords stored in your
computer can possibly be read by programs
operated by malicious users, either locally
(physically at your computer) or remotely
(through the web).
7
Online Protection
There is no fool-proof way to protect your
computer 100, with the exception of turning it
off. But you can protect it about 99 of the
time, with the right tools. There is a large
amount of software available that can protect
you and your computer. Anti-virus programs can
block trojan files, worm files, and viruses from
infecting your computer. These harmful things
can make it vulnerable to outside attacks by
malicious users. Firewall programs can keep
other computers from connecting to yours through
unguarded ports on your PC. Certain hardware
connected to your computer, such as barricades,
can 'hide' your computer from others on the web.
8
An Intro to Computer Crime
The most common Internet crime is online fraud.
This occurs when you go online, make a purchase
from someone, and the product is never delivered.
This often occurs on auction sites. Fraudulent
sites may obtain your credit card information in
order to make purchases on your credit. Some
users may become victim to email pyramid
get-rich-quick schemes. You may unknowingly
become a victim when the damage is already done.
9
Malicious Users Online
A 'hacker' is someone who enjoys the challenge
of deciphering programs and stretching the
capabilities of a program or a computer. They
are not necessarily malicious users. A 'cracker'
is a term used for persons who intentionally
codes or utilizes programs to bypass security
functions with the intent to gain private
information or unauthorized access to a computer
or number of computers.
10
Malicious Users at Work
There are programs that are available today that
allow malicious users to gain access to other
computers and their programs. They use these
hacks for several purposes, ranging from causing
simple mischief to major damage. One type of
program can 'steal' a password or passwords
allowing the malicious user to do things such as
access your email account, login to an Instant
Messenger program and pretend to be you, or
access your online banking. Another type of
program can connect their computer to yours in a
'stealth mode' where you would not even be aware.
It usually requires that your computer already
be infected by a trojan program so that same
trojan program can open up your computer to
theirs. Once done, and if the program is strong
in capabilities, the malicious user can do most
anything with your computer remotely. They could
access and view all your files on your hard
drive, turn on your microphone or webcam, erase
your hard drive(s) and even turn your computer
off. The fact remains that technology has evolved
greatly from the age of the Abacus. Protection
is what ALL users of the web need most.

Why is Cybercrime Increasing?
  • Connectivity is Global - no boundaries
  • Numerous vulnerable targets
  • Easy concealment - Anonymous Hacks
  • Low equipment costs and access
  • Less technical skill required
  • Ability to obtain tools, exploits, and
    vulnerabilities via the Web

13
Trends Methods
  • Forgery trend growing
  • Use of consumer accounts for fraud
  • Identity theft - possibly made available by your
    computer
  • Theft of Credit Card numbers
  • Online Auction Fraud
  • Child Pornography and Exploitation
  • Online Banking Fraud

14
E-commerce
  • E-commerce may reach 13 billion dollars this
    year alone
  • FDIC estimated that most banks currently have web
    sites
  • GAO estimated that 380 banks offer direct dial-in
    services
  • Booz-Allen stated, There were 16 million
    cyber-banking customers as of 2000 (and its
    growing)

15
What are we up Against?
  • Transparent technology - you cant touch this
  • Assumptions that it will take care of itself
  • Unseen background attacks by malicious users
  • Lack of Knowledge - I just dont understand this
    stuff
