I'm a little confused, I never heard the term "app farm" before I actually don't fully understand this either. If I understand correctly, the idea is for the hacker to break into peoples iTunes accounts, and then buy his own app with the stolen account? If yes, then I think the hackers "end-game" is kind of flawed, because they are bumping their own app to the top of the list, but then it will quickly get yanked as soon as Apple receives complaints that the same app is purchaced multiple times with stolen accounts. Looks like a dead-end game. I don't see any chance of "windfall profits" as the article suggests. It just looks like more "fly swatting" for Apple, nothing unusually devious, is it?

It could be similar to the way all the spam email works — sheer quantity. The success of this strategy will depend on how quickly Apple can react to reports and yank the app and on how many people are likely to purchase a $1 top-seller that caught your eye just to "check it out". So if it turns out that each app makes it to 25–50K people before Apple pulls the plug on it and you manage to do it with 20-30 apps, that's a nice little chunk of change for you. Whether or not that qualifies as windfall profit is another matter
Hmm, yea, I was thinking for it to be successful it would have to be more sophisticated and cunning, but true, "brute force" style attacks could be even more successful (look how crippling bonnets are). Still, I don't think Apple will let this "app farming" thing get too far. There's got to be a way to go after the source and shut them down... ok, even if it does turn out to be a game of "whack-a-mole"
Yes, I don't think it'll be something that has a long run, but these initial hackers may very well be getting their investment back, plus some.
