BBB Spam / chillebucks.com, sulusize.com and sulusity.com

More fake BBB spam leading to a malicious payload, this time hosted on the domain sulusize.com on 174.136.4.211 (Colo4, US). The server appears to be a legitimate hacked server, but blocking traffic to that IP is probably a wise idea if you can do it.

Some sample emails (the usual fake BBB approach):

The malware tries to download further code from sulusity.com on 209.59.220.65 (Endurance International Group, US).. another one to block. A Wepawet analysis is here.

Update #1:  another version is doing the rounds with the initial malware hosted on chillebucks.com (69.163.37.22, Bula Networks California).

Update #2: The Wepawet analysis indicates that this might do something with the user's Facebook account as well as the usual malware payload.
