Definitely, I guess as a uni student, I'm worried about the majority of non-technical students who are going to have their sessions hacked and have no clue what hit them and cannot setup proxies/tunnels. I'm not saying this isn't the site's fault. They definitely need a wake-up call.

This was already happening on a massive scale before this new app was released... I honestly don't think it will increase the number of attacks by all that much. It's brilliant as a tool for spreading the word though.

It was happening on a massive scale, but now a huge amount of really lazy people who didn't bother to do this before are. It had 3,000 downloads after 2 hours of release. The thing is, most universities have protection set up. It seems Cisco NAC is actually good for something. I never thought I'd say that. The extension certainly doesn't work on my campus.

For anyone who has SSH access to a server (but not VPN) and is wondering what to do when you need some security in a pinch, here is a quick fix... Open an ssh connection to a server you have access to using something like the following: ssh -ND 8887 -p 22 rufus@12.120.186.8 where 8887 is the port on your laptop that you will tunnel through, -p 22 is the port the ssh server is on (22 is the default but I use a differe…

Client -> SSH_Server == Encrypted

SSH_Server -> FaceBook == Unencrypted

SSH proxies are not end to end encryption. They only protect part of the path. Not sure why this is being down voted. It's true. The tunnel is only between the client and the SSH server. The HTTP websites that you visit beyond the SSH server see your clear text packets.

You can get SSL certificates for free for one domain, and they work with all browsers (except Opera, IIRC). Also, you can use Perspectives for Firefox, which I think is much better than the current system.

Off topic, but re: Perspectives. It allows your browser to compare notes with other nodes on the Internet ('network notaries') to ensure that everyone is seeing the same cert for a given website. Looks like a great idea, but how do they prevent the man-in-the-middle from impersonating a network notary?

Notaries sign their responses, if I remember correctly.

On a similar note, I have this aliased in my shell (.profile) so I don't have to think before getting a proxy up: alias socks="ssh -ND 8887 -p 22 rufus@12.120.186.8" That way I can just open a shell and type "socks" and be good to go (well and then do the system preferences deal, but I have an AppleScript that does that automatically).

Also, remember that some programs don't respect the system's proxy settings and instead use their own. Firefox is one of those, you can find its proxy settings in "Advanced -> Network -> Settings"

Unfortunately Opera doesn't support SOCKS proxies. http://www.opera.com/support/kb/view/194/

You proxy through the NSA? How brave!

Are there public SSH servers that are safe?

Surely you jest, sir!

On Mac OS X, it gives an error saying: Run --fix-permissions first. Run with which command? and how?

I found the binary "firesheep-backend" in: ~/Library/Application Support/Firefox/Profiles/ .default/extensions/firesheep@codebutler.com/platform/Darwin_x86-gcc3 I ran both: ./firesheep-backend --fix-permissions and sudo ./firesheep-backend --fix-permissions and it still asks me to run it with "--fix-permissions". I guess it's time to go digging around in the source to try and find out what it wants me to do. EDIT: Af…

I'd like to buy such a server at low purchase and maintenance cost. The Pandaboard[1] looks like a good fit, but the instructions to install a Linux distro are a bit scary [2]. I guess I could do it, from my Mac, but I'm a bit afraid to mess things up with the low-level disk utilities. Does someones sells SD cards with a distro pre-installed? Or an equivalent device with an easier setup? If not, there's probably a ma…

You can also just put DD-WRT or Tomato on your router and use that.

You're saying that the BCC server doesn't have even a self-signed SSL cert installed? Or something else?

I had a SSL certificate for a while, but actually using it throughout the site without showing users Big Scary Error Messages is not quite trivial. The activation energy for digging through several hours of edge cases was lacking... until today. ("Whoops, while you don't know you're doing it, you pull an unnecessary CSS file into the cached CSS for the registration page which references a background image on an absol…

I've seen some sites which figure out a way to force the user in and out of SSL for certain URLs. You might be able to implement a fix which forces SSL for the admin section and non-SSL for everything else.
