which is to say i'm going to exploit everyone's interest in the DNS vulnerability dan kaminsky discovered in order to draw eyeballs... in other words: made you look!...
actually, i read on the recurity labs blog that every computer security blog on the planet had written something about the DNS vulnerability, and since i hadn't done so yet i was technically making a liar out of that blogger and that's no good...
problem is, though, that for the most part i really have nothing to say about the DNS vulnerability... i don't like writing about things i don't know and DNS is one of the many times many things i don't know all that much about...
the disclosure argument that ensued was somewhat familiar territory but it wasn't until i read andre gironda's comments to rich mogull's post about whose interests are being served that things finally crystallized in my mind about this... in a nutshell, the information is such that the vast majority of people have no legitimate need or use for it and so to keep it out of the hands of the black hats it really shouldn't be broadcast for the world to see, but at the same time there are enough people that may have a legitimate need or desire to know the information that any centrally coordinated effort to inform them will fail to include many and will only result in an exercise in elitism...
believe it or not, there's actually an old lesson from the AV field to be learned here because the AV community has had to deal with a very similar situation somewhere on the order of about a million times now... long, long ago they came up with a solution that actually works pretty well: a kind of darknet where links are formed between individuals who know and trust each others motives, competence, and judgment - basically a web of trust for sharing malware samples... the benefits are that the adherents to this approach avoid contributing to the sharing of information/materials with people who have no business handling them while at the same time giving everyone who may have a legitimate need or desire for the information/materials has a fair opportunity (but not a guarantee) to acquire them by virtue of being connected to someone else (or better still, many others) who has the means and desire to acquire it themselves...
it's not a perfect system, of course... there have been some instances where the wrong person was trusted, prompting people to rethink how they decide who to trust... there has also been no shortage of lazy bums who can't be bothered to put in the work necessary to actually earn the trust of at least one of their peers and instead whine about how unfair and elitist it is, like some petulant child who feels entitled to receive whatever s/he asks for... there's nothing stopping them from building the relationships necessary to participate in such a network but some people just don't understand that nothing worthwhile in this world is free...
i really think that the wider security community would benefit from adopting a similar approach to 'disclosure', and certainly in the case of the DNS vulnerability there could have been benefits if such a distributed trust-based network had already been established and was utilized... i say "already been established" because it can take time for a trust-based network to get connected and mature; but really, from a tactical point of view, information/intelligence gathering/sharing in hostile territory (and when we talk about broadcasting things on the global stage, the presence of hostile agents is beyond doubt) requires the use of covert channels such as this...
