I've noticed a few people in the forums claimed at one point or another that the NSA supposidly has the technology to trace an OpenVPN connection directly to the user, without having to contact any of the respective server / ISP administrators, and even if multiple hops throughout the globe are used. Does anyone have any additional information on this? Is it just some rumor about the almighty NSA, or is this information well-founded? Is such an 'attack' even theoretically possible, excluding the situation where some sort of malware would get sent to the user's PC which might disclose his IP in one way or another? I would really like to hear your opinions on this as I wasn't able to find any specific information on the subject. Thanks.
