XP exploits *are* more valuable. Considering XP exploits already go for
as much as twice that, $50k actually seems reasonable, or if not
reasonable, at least what the market will bear. I haven't seen auction
boards recently (in fact since fed crackdowns it is getting harder to
get on some boards) and never saw Vista on there as it was before
Vista's time, but I have seen large amounts. While up to 6 figures for a
remote root XP exploit seems excessive, $50k for Vista does not strike
me as outrageous, all things considered.
Organized cybercrime, for lack of a better word, seems to be fairly well
organized. An aggressive business person is willing to spend money to
make money, so having multiple 0days for future business expansion would
only make sense, particularly in an area with so much unlaundered cash
floating around. If the ecommerce sites start moving to Vista and you
have remote root on Vista, burning a 0day to hit a few dozen major sites
and grab customer lists, CC #'s, etc is totally worth $50k.
Another thing to bear in mind is that some of the value here may lie in
something besides actual money. For example someone might be willing to
trade a run of CC #'s for a Firefox exploit, and if each credit card
would normally fetch $200, your exploit might be worth 50 credit card
numbers which have a street value of $10k. If you were real good at
carding you could easily turn this into twice or three times that.
Otherwise the exploit might only be worth a couple thousand in actual
cash.
