Apple acknowledges App Store hacker, advises iTunes users

A rogue App Store developer has swindled iTunes users across the globe.

Apple told Engadget Thuat Nguyen and his 42 apps were ejected from the App Store for violating Apple's developer rules. Apple suggests users check their credit card accounts for suspicious charges and then changing their iTunes password.

There are reports of users finding as much as $1,400 in unauthorized purchases.

One quick check would be to click the purchased items link in iTunes.
