What if ultrasurf malware is run under wine

Ultrasurf reputedly turns off SSL certificate checking so they can do man-in-the-middle attacks to steal your login details.

But what if ultrasurf is run under wine in linux? Then there would be no internet explorer. Linux's firefox would be set up to use the proxy at 127.0.0.1:9666 provided by ultrasurf and use its own SSL certificate checking.

Would ultrasurf still be able to turn off SSL certificate checking and do man-in-the-middle attacks?

 

no they turn it of so that the Great Firewall of China with its 3000 ITs looking after it can't see the certificate exchange and block it. Doesn't matter what you use as long as you can get on the internet with it when you live in a country which the government are dedicated to make sure you only see things they want you to see.

 

What does it mean to "turn off SSL certificate checking"? Is it a browser setting, or is it a modification of data as the data is being routed?
