What's your point? Everything that randomly generates numbers of appropriate length could hit a real one eventually. It's not a "leak," especially because it's not even for an iPhone, as requested.

This isn't news.

25% hit rate on a 15-digit sequence in the first try is leak and news.

It's not news unless it is regular. Try it a bunch of times and see how the "4 out of 5" stands up. It very well might. Or you might also not ever find another one. You won't know until you try it.

Put it this way: you can find the same sequence of numbers in the decimal digits of pi. That's not news - that's the definition of random in action.

It would be news if it was predictable and repeatable, but until someone tries it enough times to rule out it having been a total fluke, we'll never know.
