Interestingly in October 2010 many Micros customers received an e-mail that tried to get them to open a Word document relating to Micros products.
Just a normal phishing attack, however it seemed to be very targeted. Every person in our organisation that had dealings with Micros received the e-mail, those that hadn't didn't.
Got the usual - no breach, just a simple random phishing attack, which I didn't believe and contacted our account manager. I asked how it was so targeted towards users of their system, how it was global etc. They said there was no breach and that only a small number (yawn) of their customers had received it.
I was convinced it was something to do with the support portal but they said it wasn't.
I bet this is related and this breach has been ongoing since at least before that time.
