Hacker’s techniques System Hacking Who is a “hacker”? : Who is a “hacker”? There are at least two common interpretations: Someone who bypasses the system’s access controls by taking advantage of security weaknesses left in the system by developers Someone who is both knowledgeable and skilled at computer programming, and who is a member of the hacker subculture, one with it’s own philosophy and code of ethics A Brief History of Hacking : A Brief History of Hacking 1960s MIT AI Lab Ken Thompson invented UNIX Positive Meaning 1970s Dennis Ritchie invented C Phreaking : John Draper Phreaking : YIPL/TAP Phreaking : Blue boxes A Brief History of Hacking : A Brief History of Hacking 1980s Cyberspace coined 414s arrested Two hacker groups formed 2600 published 1990s National Crackdown on hackers Kevin Mitnick arrested Microsoft’s NT operating system pierced National infrastructure protection center unveiled A Brief History of Hacking : A Brief History of Hacking 2000 In one of the biggest denial-of-service attacks , hackers launch attacks against eBay, Yahoo!, CNN.com., Amazon and others.
