PNI removed a list of its clients after Brian Krebs reported on the list, but Brian notes that other clients are also posting notices: Tescophoto.com posted that it is “down for maintenance” and Rite Aid’s photo service posted a notice concerning the breach.
Sam’s Club has also posted a notice:
The privacy and the security of our members’ data is of the utmost importance. In an abundance of caution and as a result of recent reports suggesting a potential security compromise of the third-party vendor that hosts Sam’s Photo website, photo.samsclub.com, we are temporarily suspending access to the site. At this time, we do not believe customer credit card data has been put at risk. This decision does not affect any other Sam’s website or our in-club operations, including in-club photo centers.
Other clients of PNI Digital include “Samsung, ASDA (Wal-Mart UK), Hallmark UK, Blacks Photo, Loblaws, Fujifilm, Kodak, Fred Meyer, Marks & Spencer and more.”
