It's "broken window" community policing.

The more unpatched vulnerabilities there are in existence, the more lucrative it is to be involved in any part of the computing crimes community.

It's like reglazing a broken window in your neighbor's garage at your own expense, because you don't want burglars to see it and start casing other properties in the same neighborhood based on the conditional probability that a visible broken window indicates a higher incidence of other exploitable vulnerabilities.

It's also important to pursue the very easily exploited vulnerabilities, because when you get rid of all the low-hanging fruit, the people who can't already climb the tree won't survive long enough to learn how. You're cutting a lot of bootstraps so that immature criminals can't pull themselves up by them.

This is correct, and the morally sound right thing to do if you're interested in cutting down on cyber-crime, but it unfortunately falls under the incorporeal "good-boy points."

Perhaps there's a breakdown of definitions here. I've lumped bug-bounty hunters and grey hat hackers, along with actual researchers, under "researchers." Stop me now if this isn't who you're referring to.

Now if it is, this route of action goes against the reseachers' monetary incentives. It is in their wallets' interests to have criminals validating the existence of their work. As well as selling the direct findings of one's research, including even minor exploitabilities, which is a given.

If researchers were to constantly give away their work (on even little issues) it would directly lower the cumulative value of cuber-security research, i.e their more expensive projects now sell for less.

RE Broken Window.

The FBI / NCFTA invited me to speak about this vuln because it may have affected many banks at the time. (Please stop laughing.)

They called me to cancel. "Now we're all focused on this big DOS. Do you know anything about DOS that's happening today you can help us with?" I asked if the DOS is affecting the stability of the system or actually breaking anything. And they said yes it is bringing the banks down and affecting revenue.

You can read into this anecdote as you wish.

This was fascinating. Can I read more somewhere?

New York City based their increased focus on petty crimes on it. I don't think it is useful as the basis for a model of policing, though.

In some ways, it is an embodiment of the slippery slope fallacy, where if security is not perfect, it's worthless, in the same sense that a roof with one leak in it is worthless, because that one leak becomes the beachhead for further damage to the roof.

Ahh! I just realized, I read about the New York broken windows situation in Malcolm Gladwell's excellent book (in my layman opinion) The Tipping Point.

From the original article in 1982:

Consider a building with a few broken windows. If the windows are not repaired, the tendency is for vandals to break a few more windows. Eventually, they may even break into the building, and if it's unoccupied, perhaps become squatters or light fires inside.

Or consider a pavement. Some litter accumulates. Soon, more litter accumulates. Eventually, people even start leaving bags of refuse from take-out restaurants there or even break into cars.

Broken Windows, The Atlantic Monthly, March 1982
