2. Why should we worry? Crimes committed using the computer or Internet can be more costly (money wise) than other crimes (a bank robber may get $2,500 to $5,000 on average; while average loss from computer fraud is $100,000) Crimes are larger and affect more people (a hacker breaking into an e-commerce database can steal hundreds or thousands of credit card numbers) Background Information

3. Why should we worry? Crimes are harder to detect and trace (e.g., the anonymity of the Web) Computing provides new challenges for prevention, detection, and prosecution; challenges that professionals will be asked to meet.

4. Hacking - 1960-1970 Originally, a “hacker” was a creative programmer who wrote elegant or creative code. Sometimes these folks would break into the computer systems at their schools to experiment and have fun; remember that until the PC and the Internet, computing resources were quite restricted.

5. Hacking - 1970-1995 The meaning of hacker began to change. There were incidents of “trophy hacking” (doing it just to show you could do it). There were also crimes, such as thefts of information and “phone hacking” The case of Kevin Mitnick; a notorious hacker who was arrested in 1988 and finally tracked down and arrested again in 1995. He caused several million dollars of damage.

6. Hacking - 1995-present Current hacking includes all previous pranks and crimes, but now we have the intricate interconnectedness of the Web. Every networked computer is potentially vulnerable. This includes basic infrastructure (water, power, banks, hospitals, transportation, government agencies, telephone companies, etc.).

7. Hacking - 1995-present Now we have viruses transmitted via email that spread in a similar fashion to real diseases (but much faster); there often have to be quarantine procedures. The “Love Bug” from 2000 cost an estimated $10 billion in damage. De facto standard systems (e.g., Microsoft Windows and Outlook) are especially vulnerable; other systems (e.g., Mac OS) are less so; but all are vulnerable.

8. Computer Viruses More than 81,000 virus-type threats exist today. This is even more complicated because there are lots of virus hoaxes, which may be in the form of dire email warnings about disk-eating (or computer destroying!) attachments that may land in your inbox.

9. Types of Viruses Malicious worms (e.g., the Love Bug) that propagate via email and destroy the contents of computers. Denial-of-service attacks; more recently there are distributed DNS attacks. “Back-door” worms that exploit vulnerabilities to enter surreptitiously and copy private information.

10. Online Scams Auctions Sell nonexistent/faulty/etc merchandise Response Credit card required to buy or sell Escrow services -- trusted middleman Fraud response: Fraudulent escrow service Shill bidding

11. More Online Scams Stock fraud Buy a lot of worthless stock Hype it on the internet Sell it all at the new high price The SEC like to get involved in these cases

12. Identity Theft Steal credit card number: Dumpster diving Dishonest store clerks Phone customer pretending to be bank Email customer pretending to be bank

13. More Identity Theft Steal SSN (was DeFacto ID until recently) Use SSN to access records Use SSN + stolen info to get credit card Send bill to PO box ATM Fraud Fake ATM slots in front of real ATM
