Outlook email annotations McAfee Web Control

Hi,

Mfewc.exe is McAfee Web Control.

This interfaces with Outlook, via JavaScript files to annotate the emails with warning boxes.

What are the requirements, I understand it doesn't work with 64bit office.

The reason I ask is it works for some users and not others.

It doesn't even try to talk to sae.mcafee to check the malicious sites on some machines.

On my machine I can see it doing this fine.

Any ideas?

Is site advisor legacy now? And web control is it's replacement?

I've done some research on this and updated my blog with why McAfee Web Control Annotations were not loading for me.

My personal opinion: This is truly an exceptional work! I am impressed by the in depth analysis and Knowledge documents references you have included. Truly a commendable job sir!

Although the exact architectural working is not exposed in it's workflow externally by us, This is a very enlightening approach towards understanding the working. Kudos to your efforts!

Also, Just curious to understand the following:

  1. akamaitechnologies.com (It’s a CDN, so probably used to speed up web control: https://en.wikipedia.org/wiki/Akamai_Technologies)
  2. *.akamaitechnologies.com
  3. static.akamaitechnologies.com
  4. sadownload.mcafee.com
  5. mcafee.com
  6. sae.gti.mcafee.com
  7. sae.gti.mcafee.akadns.net

Of the 7 listed addresses, Can you please confirm that the ratings still work in outlook without having to white-list the following?

  1. sae.gti.mcafee.akadns.net
  2. static.akamaitechnologies.com
  3. *.akamaitechnologies.com
  4. akamaitechnologies.com

AFAIK, these sites should not affect the ratings by any means.

Once again, Excellent work done!

Re: Outlook email annotations McAfee Web Control

Hi Adithyant, thank you, just wanted to let others know my findings to hopefully help others with similar issues.

I wouldn't like to fiddle with our firewall configuration too much now it's working, but "sae.gti.mcafee.akadns.net" is a CNAME record for "sae.gti.mcafee.com" the server in which Web Control gathers its category results. 

https://mxtoolbox.com/SuperTool.aspx?action=dns%3asae.gti.mcafee.akadns.net&run=networktools#

The reason I was seeing traffic for the sites below is because the DNS provider for "sae.gti.mcafee.com" is "Akamai Technologies, inc.".

  1. static.akamaitechnologies.com
  2. *.akamaitechnologies.com
  3. akamaitechnologies.com

 No harm in allowing these extra sites through, but I would think you could probably get away with not having the three above.

Regards
