Ask HN: College hijacking all SSL certificates?
So I'm in college right now, and I noticed on my phone while connected to the college WiFi that all sites with SSL were failing to load because of a certificate error. When opening the certificate information, every single site had the same cert: issued by sw-5400-bingle
Same on the computers, only it has a green padlock here.
I know why it's possible and why it's red on phone and green on computers, but what I don't know is what the implications are. Can the college view confidential information? Can they change information in transit? At what point in the network is the hijack happening?
Is this legal/ethical?

- drakenot 10y agoIf it is on machines that the university controls, they can install a root certificate of their own and then MITM the encrypted web traffic. I've seen this a few times at large companies. All work provided machines will have the company's root cert installed and this allows them to intercept and monitor all the traffic. I'm not a lawyer but I assume that this is legal. The company is monitoring their own network and their own machines. The employees may have even signed some document during their on-boarding which further stated that the company is allowed to monitor any activity on their own equipment. I consider this an ethically grey area. It starts to become unethical in my mind if the users of the network are not explicitly told in plain language that all of their web traffic will be monitored.
- brudgers 10y agoMy default assumption for public WiFi is that someone is listening. Since I've got a GSM access point in my pocket, I always tether that instead -- sure it can be spoofed and my carrier can behave badly, but spoofing is less likely and my carrier could hit me with a drone strike anyway. Anyway, using my phone is easier because configuration is consistent, the price is the latency of establishing a new connection. In regard to a university network, there are lots of smart people who could have black or grey hacked the system. Or the university could just be exercising their position of power. In answer to the larger question, yes a Man in the Middle [MTM] attack on SSL/TLS allows eavsdropping. Good luck.

- jenkstom 10y agoThey can view and change information in transit, yes. Don't login to anything on their network because they see (and possibly log) it all. The workaround would be some sort of VPN, but my guess is that they've done their best to prevent that. I would discuss it with administration at your school. Get them to give you an answer "in writing" about why or even if they do it. Then take that to some professors. Maybe you could find some that would be offended by this whole thing, and maybe they could do something about it. Alternatively, take it to the student newspaper. If that falls through you could try other news outlets. That could be a big win, or it just go nowhere. Hard to say. But I would definitely let people know about it. There are people exposing information that they probably don't want to. Not only are there privacy concerns, but there could be concerns such as HIPAA, credit card security and possible political and safety issues for students communicating with friends or family in other countries.
- jneumann004 10y agoIf you are at a state school, you can submit a FOIA for information on the project. With a FOIA request you should be able to get the RFP and any other pertaining documents for the networking at your school. You could probably get other relevant information with a little bit of research, but I'm not sure what you would look for without a little bit of research.
