My selfish question: is my VPN still secure? This wouldn’t impact the fact that the traffic itself is encrypted, right? They’d just be able to see that my connection is behind a VPN which is communicating with other servers? Previously it was just my ISP that could know that, now the DTRA can too?
This still seems like a big security risk, though I’m not entirely sure how.
I've worked with netflow data before. All it says is time, source IP, destination IP, protocol, source and destination ports, amount of data transferred, and a guess at what type of traffic it is (http, torrent, video stream, etc). https://www.cisco.com/en/US/technologies/tk648/tk362/technologies_white_paper09186a00800a3db9.html (table 6, though most of the fields in that table aren't actually used). It doesn't include any of the data within the connection.
It wasn't previously just your ISP, it was every provider between you and the endpoint. That is, your ISP, their ISP, and the multiple backbone providers with the big pipes between ISPs (these are the ones selling the data in the article). And of course the NSA because they have a direct tap on the backbones, but they don't share that access or data with anyone.
Thank you! Super helpful.
Useful metadata to build patterns for people that are already suspected or to find patterns of bad actors.
They'll likely have to send portions of it to other agencies to get confirmation and investigations started. The amount of forensic metadata this is, just wow. Like tracking a person through a crowd by the gait of their walk, over years.
