Vector (malware)

A vector in computing, specifically when talking about malicious code such as viruses or worms, is the method that this code uses to propagate itself or infect a computer. This sense is similar to, and derived from, its meaning in biology.

Some common vectors:

  • buffer overflows – this is how the Blaster worm was able to propagate
  • HTML email with JavaScript or other scripting enhancements
  • networking protocol flaws

Web-based malware and vector

According to Provos et al., a web page is determined malicious "if it causes the automatic installation of software without the user's knowledge or consent". To increase the success rate of the vector (malware), malware is usually camouflaged by layers of code.[1] 

Types of web-based malware include:

  1. Trojan
  2. Adware
  3. Unknown/Obfuscated: "A binary that has been obfuscated so that we could not determine its functionality."[1]
gollark: I mean, *maybe* some behaviors make sense at population scale or in some bizarre game-theoretic way?
gollark: No, humans just act irrationally all the time for no good reason.
gollark: We should have neural network generated IQ tests.
gollark: You can't get some sort of highly accurate picture of intelligence out of a random test thing, but it's an approximation, sort of thing.
gollark: I think equalisers are some things for fiddling with sound balance?
