I am currently analysing an outlook email header.
I am very confused because it has two ipv4 addresses x-originating from different locations. Usually there is an ipv4 towards the top of the header and an ipv6 towards the bottom.
the emails were sent to me and I need to determine which emails were sent by a hacker by IP tracing
Could you possibly give me advice on why I would see two different ipv4 from different hosts and different locations in an outlook header when I’m meant to see one ipv4 and one ipv6?
would any vulnerability or attack cause this ?
