Dr. Richard Ford

 Fundamental Definitions  What is Malcode?  Malcode Overview  Follows: Szor Ch.1 & 2.

 Like most researchers, I got hit by a Virus  I disassembled the virus, and began on this wonderful journey of discovery…  Making every possible mistake on the way!

 MMC = Malicious Mobile Code  Critical word: Mobile  MMC is designed to move from one machine to another

 Viruses  Trojan Horses  Worms  Blended threats

 A virus is a malicious program that modifies other host files or boot areas to replicate. In most cases, the host object is modified to contain a complete copy (possibly evolved) of the malicious program code. The newly- infected object is capable of spreading the “infection” further

 A Trojan, or Trojan Horse, is a non-replicating program masquerading as one type of program with its real intent hidden from the user.

 A worm is a piece of replicating code that uses its own program coding to spread with minimal user intervention. Unlike viruses worms do not “infect” other programs or boot sectors

 Replication + something else bad (like an exploit)

 A technology that aids in gathering information about a user or content of a machine without that user’s knowledge

 Pretty much Spyware that tells you exactly what it’s going to do…  Always read the EULA…

 Colloquial but descriptive  “Any piece of software that the user doesn’t want”

 In The Wild  Dr0pper  “Generation 0”<- this is a zero  Payloads  Rootkit

 Interesting problem  Go ahead and read: 03/ pdf: (p14) That Which We Call Rose.A 03/ pdf  What really is in a name?  For the other side, read 1/caro.xml or Szor Chapter 2, /caro.xml or Szor Chapter 2

 What is the goal of virus naming?  Assignment: Read Szor Ch.1 & 2 for Tuesday’s class

 Is there any such thing as a good virus?  What do you think about this: terfriendly.asp?p=337309&rl=1 terfriendly.asp?p=337309&rl=1

 Viruses and their environment…
