@georgetakei when they first started appearing widely in the UK, I had a conversation with a checkout operator who asked if I wanted to sign up to be given a discount on my current purchase, paraphrasing , I replied "I come here so often you know me by name, but without the card I'm not considered loyal. The card and reward are nothing to do with loyalty. So, no thanks."
@arstechnica@Viss I wish articles like this would include, up front, the indicators of compromise that I can use to test if the servers I manage are affected. It's the first and most important thing I want to know when learning about a vulnerability.
