Got an email on Saturday thanking me for my $66 order at McDonalds in Redcliffe QLD, only thing is I am in NSW.
I thought it was one of those spam/scam emails baiting me to change the password until I checked my Amex and the charge is real.
I then got a second email 5 minutes later for another $43.70 order in the same place.
I proceeded to delete my saved amex card and change the password.
Called Amex to dispute the charges, report it as a Cybercrime and made a complaint with McDonalds.
I can see that McDonalds have implemented two factor authentication is other coutries such as Malta and the UK but not in Australia. I read that this has happened to another user just two days ago.
