Usually with these of types of scams there's a phishing link inside the email. However, there are no clickable links in this email and appleid.apple.com is an official Apple site.
In between the regular English characters there are letters and numbers scattered around with a font size of 0 and a transparent colour. There are also a couple of HTML tags with apparently random text. Example of the HTML code:
Th<font style='color:transparent;font-size:0px'>6</font>e<font style='color:transparent;font-size:0px'>n</font> <font style='color:transparent;font-size:0px'>c</font>f<!xklyv>o<font style='color:transparent;font-size:0px'>4</font>l<font style='color:transparent;font-size:0px'>k</font>l<!z5y08>o<font style='color:transparent;font-size:0px'>4</font>w<font style='color:transparent;font-size:0px'>a</font>i<!g>ng <font style='color:transparent;font-size:0px'>h</font>c<font style='color:transparent;font-size:0px'>y</font>h<font style='color:transparent;font-size:0px'>0</font>a<font style='color:transparent;font-size:0px'>d</font>n<font style='color:transparent;font-size:0px'>5</font>ge<!ctubo>s to<font style='color:transparent;font-size:0px'>i</font> <!vg>yo
The body of the text actually looks like the following: if y0o0ua td5id 2nao5t bmakpe thebs0ev ch5angmes momrh ipfc you bvelsieveh ban unauthorised9 uperson9 dhas zaccesuse9d dymo2u2r accouxnsth
How does this phishing email work? Does something happen just by opening the email?
