Let me start by saying I’m computer literate.
I received an email (Office 365 downloaded to my local Outlook client) with a PDF attachment. An invoice with banking details for payment at the bottom.
I forwarded this email the finance department (ISP Mail service downloaded to a local Outlook client) and when the email arrives it has a different account number in the pdf.
Anyone know of any malicious software able to scan and change data in a PDF?
Or a man in the middle attack?
