infection

from here (note: for those unfamiliar with the slang, "pwned" is a synonym for "compromised")

much like like the term "virus", "infect" is misused a lot. in fact, each misuse implies the other.

as the comic implies, the distinction is important because how we respond depends a great deal on what we're responding to. if we get confused by sloppy word choice we're liable to make a sloppy action choice.
