swi_fc.exe connecting to Malicious Domain

skyisbluescreen

On the firewall a system was detected trying to establish a connection to a Malicious Domain. Further when drilled down this were automated web requests. 

DOMAIN i tried contacting--> 

Threat - www-x-nanfpump-x-com.img.abc188.com
Category - Malicious Websites
 
Further Investigated and the File involved was 
swi_fc.exe [Path : "c$\Program Files (x86)\Common Files\Sophos\Web Intelligence\swi_fc.exe"]
 
This shows up on FIREWALL & Other End Point Analytics Tool
 
QUESTIONS : 
- Not sure why Web Intelligence Service is involved in generating this traffic ?
 
 NOTE : 
-No Events on SOPHOS Dashboard for specific client Virus \ Web Events
-The executable swi_fc.exe on the system i checked against VIRUS TOTAL. It is not infected and shows Clean
-The malicious Domain is accessed over PORT 33 and i have verified the Domain is Malicious against other URL Categorization vendors.

    swi_fc.exe is the endpoint process that proxies browser traffic if web control or web protection features are enabled.  I.e. Chrome.exe/iexplore.exe etc talk via loopback to this process and this process makes the outbound connection.  So it does make sense that this process is connecting to the site in question.

    True Jak. My understanding was same. However let me check deeper if its some other executable and swi_fc.exe is just tying to lookup the address
