CVS shuts down photo website in wake of possible hack, theft of credit card numbers

CVS is warning customers that its online photo service may have suffered a data breach and has shut it down.

The nation's second-largest drugstore chain says the site is being switched off as a precaution and that it has also sealed off related mobile device apps.

Payment information on the site is collected by an outside vendor, CVS Health Corp. says, and it's kept separate from its main CVS.com website and the computer system used in its pharmacies. Payments made through CVS.com and in CVS stores are not affected.

The company wouldn't say how many customers could potentially be affected.
