- 2. Introduction to Cyber Crime Computer Crime, E-Crime, Hi- Tech Crime or Electronic Crime is where a computer is the target of a crime or is the means adopted to commit a crime. Most of these crimes are not new. Criminals simply devise different ways to undertake standard criminal activities such as fraud, theft, blackmail, forgery, and embezzlement using the new medium, often involving the Internet
- 3. Computer vulnerability Computers store huge amounts of data in small spaces Ease of access Complexity of technology Human error One of the key elements that keeps most members of any society honest is fear of being caught — the deterrence factor. Cyberspace changes two of those rules. First, it offers the criminal an opportunity of attacking his victims from the remoteness of a different continent and secondly, the results of the crime are not immediately apparent. Need new laws and upgraded technology to combat cyber crimes
- 4. Different Types of Cybercrimes Cyber crimes Hacking Information Theft E-mail bombing Salami attacks Denial of Service attacks Trojan attacks Web jacking
- 5. Types of Cyber crimes Credit card frauds Cyber pornography Sale of illegal articles-narcotics, weapons, wildlife Online gambling Intellectual Property crimes- software piracy, copyright infringement, trademarks violations, theft of computer source code Email spoofing Forgery Defamation Cyber stalking (section 509 IPC) Phising Cyber terrorism Crime against persons Crime against Government Crime against property
- 6. E-Mail bombing: Email bombing refers to sending a large amount of e-mails to the victim resulting in interruption in the victims’ e-mail account or mail servers. Data diddling: This kind of an attack involves altering the raw data just before it is processed by a computer and then changing it back after the processing is completed. Salami attacks: These attacks are used for the commission of financial crimes. The key here is to make the alteration so insignificant that in a single case it would go completely unnoticed e.g. A bank employee inserts a program into bank’s servers, that deducts a small amount from the account of every customer Denial of Service: This involves flooding computer resources with more requests than it can handle. This causes the resources to crash thereby denying authorized users the service offered by the resources. TYPES OF CYBER CRIMES
- 7. Some common cybercrimes… Phishing, the mass distribution of “spoofed” e-mail messages, which appear to come from banks, insurance agencies, retailers or credit card companies and are designed to fool recipients into divulging personal data such as account names, passwords, or credit card numbers. “Carding,” which entails using stolen credentials (and can include package reshipping, money moving, and identity theft schemes) Compromised servers or “bots,” which may be launching cyber attacks or sending Spam
- 8. Cyber Crime Data In Regional Context Carding:- Carding is a serious threat to India, as it does not require a high degree of sophistication and is considered particularly pernicious by international financial institutions and e-commerce providers. Bots:- Bots, compromised servers that may be launching cyber attacks or sending Spam, were detected in the India IP space, including servers with the domain name. Phishing:- ISPs were able to point to a few examples of phishing capture sites being located on their servers, one targeting eBay (a frequent attack point for phishers).
- 9. Computer Viruses Viruses A computer virus is a computer program that can infect other computer programs by modifying them in such a way as to include a (possibly evolved) copy of it. Note that a program does not have to perform outright damage (such as deleting or corrupting files) in order to be called a "virus". A computer virus is a program that can copy itself and infect a computer without permission or knowledge of the user.
- 10. Why Do people Create These Viruses? To distribute political message. To attack the products of specific companies. Some consider their creations to be works of art, and see as a creative hobby. Financial gain from identity theft
- 11. Types of Viruses Types of viruses Armored virus Companion virus Polymorphic virus Macro virus Boot sector virus Stealth virus Logic bomb Sparse infector Network viruses
- 12. Cyber Threats Cyber Threats Cyber threats to a control system refer to persons who attempt unauthorised access to a control system device and network using a data communications pathway. Main threats to cyber crime is Hacking. Hacking involves gaining unauthorised access to a computer and altering the system in such a way as to permit continued access, along with changing the configuration, purpose, or operation of the target machine, all without the knowledge or approval of the systems owners.
- 13. New Internet Threats All computers need internet security Home users can lose valuable personal data with one click to the wrong website. Children trading games also exchange viruses unknowingly. You receive an email requesting an update to your payment details, and a hacker gains access to your bank account. A backdoor is installed on your machine, and your PC becomes a zombie, spewing out spam. New technologies - new anti-malware solutions As cyber threats have evolved, so has software to deflect such threats. Sophisticated antispyware and antivirus solutions capable of detecting the most complex new viruses are now available.
- 14. What Is Spam Spam is the equivalent of physical junk mail and unsolicited telemarketing phone calls. It has become one of the largest nuisances to computer users for both home and business users. There are two main types of spam, and they have different effects on Internet users.Cancellable Usenet spam is a single message sent to 20 or more Usenet newsgroups. (Through long experience, Usenet users have found that any message posted to so many newsgroups is often not relevant to most or all of them.) Usenet spam is aimed at "lurkers", people who read newsgroups but rarely or never post and give their address away. Usenet spam robs users of the utility of the newsgroups by overwhelming them with a barrage of advertising or other irrelevant posts. Furthermore, Usenet spam subverts the ability of system administrators and owners to manage the topics they accept on their systems. Email spam targets individual users with direct mail messages. Email spam lists are often created by scanning Usenet postings, stealing Internet mailing lists, or searching the Web for addresses. Email spams typically cost users money out-of-pocket to receive. Many people - anyone with measured phone service - read or receive their mail while the meter is running, so to speak. Spam costs them additional money. On top of that, it costs money for ISPs and online services to transmit spam, and these costs are transmitted directly to subscribers.

Some registrars are quick to set things right when these cases are discovered. However, it is well documented that some registrars will admit no fault in accepting the forged credentials and will refuse to correct the record until forced by legal action. In many of these cases, justice is not done and the hijacker retains control of the domain.

Email worms
- 50. Password Authentication protocol Password authentication protocol, sometimes abbreviated PAP, is a simple authentication protocol used to a network access server used for example by internet service provider. PAP is used by point to point protocol. Authentication is a process of validating a user before allowing them access to server resources. Almost all network operating system remote servers support PAP.
- 51. 10 Ways To Wireless Security Use encryption - chances are bad guys won’t bother breaking it. Use strong encryption - in case they are trying to break it, make it harder for them. Change the default admin password - avoid using ‘password as the password. Turn off SSID broadcasting - don’t ’shout’ to everybody in the neighborhood "come and try me." Turn off WAP when not in use - do you leave your TV on running when you are not at home?
- 52. 10 Ways To Wireless Security Change your default SSID - yes, there are at least 50 other ‘linksys’ stations around, and they are easier to find. Use MAC filtering - you give keys to your home only to trusted people - do the same with the wireless network. Isolate the wireless LAN from the rest of the network - why did you think Titanic sank? Create levels of protection. Control the wireless signal - unless you want to power the whole city, there is no need to use signal amplifiers. Transmit on a different frequency - this is why we haven’t intercepted the aliens yet
