It's spam - welcome to email.

Subject: [ActiveDir] Spoofed emails



Dear list,

For the past couple of weeks, a few staff members were receiving emails with 
the 'Subject', 'From', and 'To' fields being blank. It was not taken too 
seriously until I received such an email. In the advent the zero-day exploits 
such as the WMF, I realize what a big security problem this can be. Imagine if 
this email was sent last week with an image attached and upon viewing it, would 
run code taking advantage of the aforementioned exploit.

Below is the actual email header with server names just with type of server:

 

 Microsoft Mail Internet Headers Version 2.0

I was going to call the ISP to whom this address is registered to and notify 
them of email abuse generating from within their network but, I received 
another email from a different address (213.226.189.173) so I am thinking that 
the addresses are spoofed.

Any help  in shedding light into this situation would greatly be appreciated.
