AppleID purchase scam
Recently I received an email from an unknown user about a purchase.
My main concern is more so about the PDF file attached and it's contents.
The only "link" I clicked on while viewing the PDF receipt was a "Report Problem" tag, as the PDF was made to mimic an official Apple email receipt.
Though I was only taken to a "403 error" and no actual site. Nothing else was prompted nor occurred afterwards. But I am taking precautions and changing passwords while also running a scan on my computer.
Seeing as nothing alarming has happened, I need to know if there's something i'm missing, or need to do, otherwise i'm unsure if i'm safe.
Sincerely, Very Paranoid~
