Hello, welcome to the Friday, December 9th, 2016 edition of the Sands and at Storm Center's

0:05.9

Stormcast. My name is Johannes Ulrich, and I'm recording from Jacksonville, Florida.

I wrote up a little bit an older event today. December 1st, I received an email that was made

0:17.7

to look like an abuse notice, like I did something wrong with one of my domains,

0:23.0

and it came from an entity that called itself domain cops.

0:27.3

Now, they actually registered domaincops.net,

0:31.3

and the email came from a legitimate mail server

0:34.8

that was associated with that domain, in that the email was signed with

But in general, in particular, the help desk individuals and the like in your

1:28.1

organizations that may be receiving notices like that, they of course have to be aware that they

1:33.9

should expect malicious attachments once in a while as well. I have seen others use attachments

1:40.7

and use links like that in order to substantiate an abuse report.

1:46.1

Trying to avoid this myself, but sometimes there's just too much data.

1:49.7

So you post an excerpt of the data in the email itself, but then link to the rest of the data

1:57.4

via a URL.
