PCGS - Data Security issue (alert)

[Ozcoins]

Given the small amount of info divulged in the notification by PCGS of the problem they had,  I would suspect they
A. Do not know exactly what info was stolen
and/or
B. Will not talk to anyone about what they do know (to hide how bad it was)
Having said that, it seem unlikely that the location your card was used is at all related to where the info about your card was taken.
