Update 6/17/19: Giftcardmall has confirmed a data breach has occurred. If you used the site between April 24th and May 21st, 2019 then your information is likely to have been accessed. Full letter sent out below.
They are also stating that there is no evidence your personal information was actually accessed, but lots of readers originally reported fraudulent transactions on their credit cards so I’m not sure how that’s remotely accurate. I’ve said it before but I’ll say it again, until the penalties for data breaches increase they will continue to occur at an alarming rate. Hat tip to lobonomnom
[Reposting on 5/28/19 as an additional reminder since it appears that many/most cards used on Giftcardmall are affected; tons of people reporting unauthorized charges. Keep a sharp eye on your cards, or even just ask the bank to replace your card.]
A number of users on reddit are reporting that cards that were only used to make purchases at giftcardmall have had fraudulent purchases made at other stores. Reddit user lobonomnom also reports that Norton detected a formjacker on the checkout page, but I was unable to replicate that result. Has anybody else noticed something similar?
