All companies that accept credit cards have agreements with the card companies. Penalties for stuff like this start at $500,000 dollars. Technically Apple is required to report incidents like this but they probably do it on an individual account basis thereby avoiding the repercussions.

I wonder if tomorrow we’ll see a bunch of open Apple headcount recs for IT security experts...;)
