That's a good point; though I am now wondering if the Equifax breech got noticed before it was owned up to.
Going back to the higher point; I do wonder what the Chinese Govornment's track record on cyber security actually is, compared to what we more usually hear reported.
I don’t know if I would go public in China if I noticed a breach like that. I have never lived there, but I imagine the climate encourages a bit more discretion.
