A "remote hack" generally relies on a stack of exploits. From what I recall when the last jailbreaks came about, that stack was at least 5 or so exploits deep.

A "remote hack" generally relies on a stack of exploits. From what I recall when the last jailbreaks came about, that stack was at least 5 or so exploits deep. So $1M/exploit is priced significantly ahead of the $2M/hack. Interesting this also means that an entire exploitable stack now becomes worth a lot more, while any given exploit is worth a lot less. And any stack of exploits becomes much more brittle, as a patch of a single one of N exploits can knock out the use of the stack.
