So I went over quite a lot of topics here and on the internet.. but I still can't seem to completely understand this issue. How secure really are services like proxies, VPN or VPS?
VPN is promoted everywhere as being safe. Proxies have different levels of anonymity.
But is there a possibility, that a VPN provider would have something like Wireshark running on the machine to track all the traffic? Would you be watchful using any of the above services for online payments (paypal, credit card) ?
I understand that (if configured correctly) the chances of a 'man in the middle' can be quite low. But as I said, what if the provider himself is interested in violating the user's privacy?
