HACKER, DO NOT PURCHASE

I went to my gmail and had a receipt from Apple for this app (free) and $14.98 of in-app purchases (not free). It drained my gift card balance from $15 to $0, and the scary thing is that it appears to have happened exactly the same way to other people–Im willing to bet that the other people who were hacked had exactly the amount on their itunes balance that was drained.
APPLE. HELP ME OUT HERE. NOW.
