INFO: How to Block Hopster Connecting through Vital Security

Expand / Collapse
Show/Hide Article Tools


  • Description
    Hopster works by tunneling everything though corporate proxies as HTTP requests back to their own servers, and then proxying anything that the end-user is using.
    The program acts as a socks proxy on the local PC and can be used by any program that supports the use of a socks proxy.

  • Symptoms
    End-users can browse to all sites and use Hopster messenger clients without being blocked.

  • Cause
    The Hopster client hides the clients' traffic by tunneling all traffic using the HTTP protocol to a central Hopster proxy server.
    It uses the corporate proxy server to connect to this Hopster proxy server but bypasses the corporate proxy policy.

  • Solution
    Create an URL list containing the Hopster proxy server(s) on the internet.
    Currently there is only one with IP: 62.116.83.62

    Create a policy rule that blocks tunneled http traffic to the URL list defined above.





    A similar solution might be applicable for the alternative clients listed above.
