    Possible Security Issue - Event Viewer


    Recently I have received 2 DNS Client Events in the Event Viewer which may indicate malware attempt.

    Event Viewer

    Name resolution for the name a.rfihub.com timed out after none of the configured DNS servers responded.

    Recently, a new browser hijacker virus has attacked thousands of computers, called Rfihub.com.

    Name resolution for the name adrtb.liverail.use.1.sunday.sky.com timed out after none of the configured DNS servers responded.

    I suppose the fact the server did not respond is good ? I use Windows Defender and Malwarebytes (free) to scan. Neither reports any problem.


    Is this a concern ? Anyone experienced similar entries in the Event Viewer ?

    I've seen similar events several times in event logs in BSOD section posted by other people.

    According to: rfihub.com third party host search results | Cookiepedia


    This domain is owned by Rocketfuel. The main business activity is: Advertising


    The main purpose of cookies set by this host is: Targeting/Advertising

    Having restrictive firewall and good browser add on to block tracking and adds is the way to go, to defend against this scum Firm.

    Thanks for the reply.

    What is meant exactly by "timed out after none of the configured DNS servers responded." Blocked by firewall ?

    Configured DNS servers are configured in your network adapter.

    To figure out why they do not respond try to manually query and see output:
    Click image for larger version

    The above request timed out because there is no such domain.
    it does not mean that 8.8.8.8 server ( which is google server ) does not respond.
    DNS client resolution timeouts

    You can input:
    nslookup
    set debug
    adrtb.liverail.use.1.sunday.sky.com


    to see verbose output by using your configured DNS server(s).

    Real question is why does your machine query these domains?
    It's most likely that adds contain domains which your browser need to resolve in order to display scum content
