Hackers Presented by: Kevin Regaldo Phillip Dai
Hacker Defined… • Hack (used with computers) verb : • to devise or modify (a computer program), usually skillfully. • Hacker: • Person who delights in having an intimate understanding of the internal workings of a system, computers and computer networks in particular. • Hacker definition controversy: • Good Hacking vs. Bad Hacking
Kinds of Hackers • Black Hat: • Specialize in accessing networks, remote computers, and/or uses of technology without interest in legality of action. • White Hat: • Specialize in penetration testing, such as testing own security system, often work as security consultants. • Grey Hat: • Hacker with borderline ethics may or may not commit crimes during course of exploits. • Script Kiddie: • Derogatory term used to describe those who use programs developed by others to attack computer systems.
Common Programs • Vulnerabilty Scanner: • Check computers on a network for know weaknesses, Comparable to a port scanner which looks for open “ports” on a computer. • Packet Sniffer: • Captures data packets used to capture passwords and other data. • Trojan Horse: • Sets up a back door in a system which allows the intruder access later. • Keyloggers: • Tool designed to record keystrokes, usually combined with virus, worm, or Trojan horse to remain hidden.
Tech Model Railroad Club • Tech Model Railroad Club (TMRC) • Where “hackers” originated. • Signals and Power Subcomittee would literally ‘hack’ into the power and relays to either improve performance or fix a problem. • TMRC “hackers” became the nucleus of MIT’S Artificial Intelligence Lab in early 80’s.
Phreaking • Phreaking : Phone + Freak • Single Frequency Phone Lines • Multi-Frequency Phone Lines • 1957, Joe Engressia discovered whistling forth E above middle C or 2600HZ would cause the switch to think the call was over which left the system open to exploitation. Provided free long-distance and international calls
Bulletin Board Systems • Computerized Bulletin Board System • Started in Chicago 1978 by Ward Christensen and Randy Suess. • Went online in Feb 16, 1978 • Computer system running software that allows users to connect and log into system. • Predecessor to internet forums/chat rooms. • Accessed only over a phone line using a modem.
Dawn of modern computational hacking • BBS became popular, served as a meeting ground for previously scattered phreakers to share discoveries and experiments. • Since BBS was accessed through phone lines, early hackers would use phreaking methods to find open lines and modem numbers belonging to businesses .
Kevin Mitnick • Black Hat • Started exploiting bus punch cards to get free rides. • Hacked: • Computers • Stole corporate secrets • Scrambled phone networks • National defense warning system
Aftermath… • 2 ½ year coast-to-coast hacking spree • “The most wanted computer criminal in United States history” –The Department of Justice • Arrested in 1995 • Charged with breaking into the Digital Equipment Corporation’s network and stealing software. • 5 years in prison (8 months of solitary confinement)
Today • Inspired 2 movies: • Freedom Downtime • Takedown • Computer security consultant • Author/Speaker • The Art of Intrusion • The Art of Deception
Tsutomu Shimomura • Research scientist in computational physics • Got hacked by Kevin Mitnick • White Hat • Helped FBI track down Mitnick • Computer security expert for NSA.
Tim Berners-Lee • Computer scientist • MIT Professor • World Wide Web • Works for UK govt. to help make data more open and accessible on the web • Net Neutrality: • “Connectivity with no strings attached.”
