Has anyone yet encountered an SSL proxy app called, Ultrasurf? Found some students using it yesterday to bypass our filter and it's quite clever. It creates an SSL tunnel on alternating ports to a variety of proxy addresses. Our Barracuda web filter won't block it because it doesn't see the encrypted traffic. It looks like I'll probably need to block it at the workstation level using Zenworks/Grouppolicy..... Also found this little windows service someone wrote that seems to stop it:
Jeez... If the tools are out there to get around the Great Firewall of China, they'll probably have a good shot getting through our filters.
Anyone dealt with Ultrasurf yet?
