  2. Types of Assaults on Computers and Networks • Spyware-software made by publishers that allow them to snoop on your browsing activity, invade your privacy, and flood you with those horrible pop-ups. • Identity theft- • Virus-a software program capable of reproducing itself and usually capable of causing great harm to files or other programs on the same computer; "a true virus cannot spread to another computer without human assistance" • Worm-a software program capable of reproducing itself that can spread from one computer to the next over a network; "worms take advantage of automatic file sending and receiving features found on many computers“.

  3. Types of Assaults on Computers and Networks • Trojan Horse-A computer program is either hidden inside another program or that masquerades as something it is not in order to trick potential users into running it. For example a program that appears to be a game or image file but in reality performs some other function. The term "Trojan Horse" comes from a possibly mythical ruse of war used by the Greeks sometime between 1500 and 1200 BC

  4. Types of Assaults on Computers and Networks • Social Engineering-An attack based on deceiving users or administrators at the target site. Social engineering attacks are typically carried out by telephoning users or operators and pretending to be an authorized user, to attempt to gain illicit access to systems • Sniffing usernames/passwords-An attacker puts a computer on your network into "promiscuous mode", listening to every bit of traffic that goes by on the network and captures all the data. Normally a computer's network connection ignores traffic that is not addressed to it, but when sniffing the computer will pick up everything. This is an easy way to pick up clear text passwords. e-mail programs frequently use clear text passwords. Many users use the same password for everything. This allows an attacker to crawl deeper into your network. • Spoofing-Pretending to be someone else. The deliberate inducement of a user or a resource to take an incorrect action. Attempt to gain access to an AIS by pretending to be an authorized user. Impersonating, masquerading, and mimicking are forms of spoofing.

  5. The Gathering of Information • Hard Drive- Hard drive-A rigid non-removable disk in a computer and the drive that houses it. Hard disks store more data and can be accessed quicker than floppy disks • Log files-A file that lists actions that have occurred. For example, Web servers maintain log files listing every request made to the server. • IP address- Internet Address

  6. The Gathering of Information • Caller ID- A telephone service that provides for subscribers the name and telephone number of a caller, which appear on a display as the call being received. • Email- A system for sending and receiving messages electronically over a computer network, as between personal computers.

  7. Protection tactics • Anti-virus-A software program designed to identify and remove a known or potential computer virus. • Firewall-Computer Science. Any of a number of security schemes that prevent unauthorized users from gaining access to a computer network or that monitor transfers of information to and from the network.

  8. Protection tactics • Anti-spyware- ware-software that protects against spyware.

  9. The True Identity Of A Criminal • Criminals are portrayed as evil and not sociable • The true identity of cyber crime is "Hackers” • Hackers come in many different types

  10. Finance In Cybercrime • Internet-related stock fraud results in $10 billion per yearin Fall 2000 • In October 2000 a group of about 20 people, some of whom were connected to mafia families, working with an insider, created a digital clone of the Bank’s online component. It then planned to use this to divert about $400 million allocated by the European Union to regional projects in Sicily.

  11. Finance In Cybercrime • In Fall 2000 when a variation of the Love Letter worm was used in an effort to gain access to account passwords in the Union Bank of Switzerland and at least two banks in the United States. • 500 companies that responded to a recent FBI survey, 90 percent said they'd had a computer security breach, and 80 percent of those said they'd suffered financial loss as a result.
