- 3. Powerpoint Templates Page 3 oVERVIEW oF HACKING 3 • Hack – the rapid crafting of a new program or the making of changes to existing, usually complicated software • Hacker – The person who hacks • Cracker – System destroyer
- 4. Powerpoint Templates Page 4 TYPES oF HACKER 3 White Hat Hackers: A White Hat who specializes in penetration testing and in other testing methodologies to ensure the security of an organization's information systems. Black Hat Hackers: A Black Hat is the villain or bad guy, especially in a western movie in which such a character would wear a black hat in contrast to the hero's white hat. Gray Hat Hackers: A Grey Hat, in the hacking community, refers to a skilled hacker whose activities fall somewhere between white and black hat hackers on a variety of spectra.

- 6. Powerpoint Templates Page 6 HACKER’S LANGuAGE 1 -> i or l 3 -> e 4 -> a 7 -> t 9 -> g 0 -> o $ -> s | -> i or l || -> n |/| -> m s -> z z -> s f -> ph ph -> f x -> ck ck -> x
- 7. Powerpoint Templates Page 7 HACKER’S LANGuAGE TRANSLATIoN • Ex: –1 d1d n0t h4ck th1s p4g3, 1t w4s l1k3 th1s wh3n 1 h4ck3d 1n –I did not hack this page, it was like this when I hacked in
- 8. Powerpoint Templates Page 8 What is Ethical hacking • It is Legal • Permission is obtained from the target • Part of an overall security program • Identify vulnerabilities visible from Internet at particular point of time • Ethical hackers possesses same skills, mindset and tools of a hacker but the attacks are done in a non-destructive manner • Also Called – Attack & Penetration Testing
- 9. Powerpoint Templates Page 9 Why Do WE nEED Ethical hacking Viruses, Trojan Horses, and Worms Social Engineering Automated Attacks Accidental Breaches in Security Denial of Service (DoS) Organizational Attacks Restricted Data Protection from possible External Attacks

- 11. Powerpoint Templates Page 11 1. REconnaissancE This is also known as foot-printing. This is the first stage in the methodology of hacking. As given in the analogy, this is the stage in which the hacker collects information about the company which the personal is going to hack.
- 12. Powerpoint Templates Page 12 2. scanning Scanning is the second phase in the hacking methodology in which the hacker tries to make a blue print of the target network. It is similar to a thief going through your neighborhood and checking every door and window on each house to see which ones are open and which ones are locked.
- 13. Powerpoint Templates Page 13 EnuMERation Enumeration is the ability of a hacker to convince some servers to give them information that is vital to them to make an attack. By doing this hacker aims to find what resources and shares can be found in the system
- 14. Powerpoint Templates Page 14 3. gaining accEss This is the actual hacking phase in which the hacker gains access to the system. The hacker will make use of all the information he collected in the pre-attacking phases.
- 15. Powerpoint Templates Page 15 4. Maintaining access Now the hacker is inside the system by some means by password guessing or exploiting some of its vulnerabilities. This means that he is now in a position to upload some files and download some of them.
- 16. Powerpoint Templates Page 16 5. covering tracks Now we come to the final step in the hacking. There is a saying that “everybody knows a good hacker but nobody knows a great hacker”. This means that a good hacker can always clear tracks or any record that they may be present in the network to prove that he was here.
- 17. Powerpoint Templates Page 17 17 History of cryptograpHy • Cryptanalysis studies the process of breaking encryption algorithms • When a new encryption algorithm is developed, cryptanalysts study it and try to break it – Or prove that it is impractical to break it (taking much time and many resources)
- 18. Powerpoint Templates Page 18 18 enigMa • Used by the Germans during World War II – Replaced letters as they were typed – Substitutions were computed using a key and a set of switches.
- 19. Powerpoint Templates Page 19 19 steganograpHy • The process of hiding data in plain view in pictures, graphics, or text – Example: changing colors slightly to encode individual bits in an image • The image on the left contains the image on the right hidden in it.
- 20. Powerpoint Templates Page 20 20 syMMetric cryptograpHy algoritHMs • Symmetric algorithms have one key that encrypts and decrypts data • Advantages – Symmetric algorithms are fast – They are difficult to break if a large key size is used – Only one key needed
- 21. Powerpoint Templates Page 21 21 syMMetric cryptograpHy • One key encrypts and decrypts data • Cleartext with Key makes Ciphertext • Ciphertext with Key makes Cleartext Winning Lotto #s: aWDHOP#@-w9 aWDHOP#@-w9 Winning Lotto #s:
- 22. Powerpoint Templates Page 22 ETHICAL HACKING TOOLS • Samspade Samspade is a simple tool which provides us information about a particular host. This tool is very much helpful in finding the addresses, phone numbers etc • Email Tracker and Visual Route We often used to receive many spam messages in our mailbox. We don’t know where it comes from. Email tracker is software which helps us to find from which server the mail does actually came from. Every message we receive will have a header associated with it. The email tracker uses this header information for find the location.

Powerpoint Templates Page 23 SOmE CASES Of HACKING • Sony - Around 77 million users of Sony’s Play station network could have had their information stolen by hackers in April 2011. • RSA Security - In March 2011, RSA Security was hacked when a spoof email containing an infected Excel spread sheet tricked employees into allowing hackers to access the system. • InfraGard Atlanta - As an FBI partner, you would imagine InfraGard Atlanta to have the most up-to-date Internet security available. However, in June 2011 the company was hacked and 180 usernames and passwords were stolen. • Gmail - The Gmail accounts of Chinese human activists were hacked, suggesting that the Chinese government masterminded this attack, especially because of the widespread restrictions within the country.
- 24. Powerpoint Templates Page 24 SKILLS Of AN ETHICAL HACKEr • Routers - knowledge of routers, routing protocols and access control lists. • Microsoft - skills in operation , configuration and management. • Linux - knowledge of Linux/Unix; security setting, configuration, and services. • Firewalls - configuration, & operation of intrusion detection systems.
