Looks like this just hit me for a minor annoyance. I just got an e-mail from Chase to confirm an attempted $50 charge at a Walmart in Toledo on my IHG Mastercard. I logged into my account and see pending charges for $50, $51.48 and $50 at the same Walmart. I only use this card if staying at an IHG property so it is no big deal. I stayed at one of the affected Holiday Inns in TN late last year so I'm guessing that is where the hack came from.
