Dissidents Seeking Anonymous Web Solutions?

DocMurphy asks: "I'm working with some dissidents who are looking for ways to use the Internet from within repressive regimes. Many have in-home Internet access, but think it too risky to participate in pro-freedom activities on home PCs. Internet cafés are also available, but although fairly anonymous, every machine may be infected with keystroke loggers that give governments access to and knowledge of 'banned' sites. Dissidents not only want to remain anonymous themselves, but also wish to not compromise the sites they access. Any suggestions for products/procedures/systems out there making anonymous access & publishing a reality under repressive regime run Internet access?"

    Internet cafés are also available, but although fairly anonymous, every machine may be infected with keystroke loggers that give governments access to and knowledge of 'banned' sites.

    I would think that Internet Café "spies" would be more useful than keyloggers to the authorities looking for dissidents. Unless these connections are somehow routed through multiple anonymous/encrypted proxies and hopping through open WAPs I really don't believe that a public terminal is in any way "safe".

    A stalker that I had earlier this year was easily located via tracking his IP and figuring out which coffee shops and libraries he was using. The libraries all went through a single county-wide proxy and narrowing his location down on a Sunday was easier than you could possibly imagine (all satellite locations in the county were closed except one).

    If I could track someone down that easily imagine what the members of a Gestapo looking to do more than end some harassing emails could do, especially when they might have a network of spies watching public access locations in person.

      Just beefing that up a bit...

      In general keep needed software and materials off the machine, on usb key only. Ideally, use an OS with no swapping. Keep the USB key in a shielded housing when not in use to prevent locating it due to active components.

      Regularly use the machine for innocuous activities, so that there is a record of something. Regularly use an identical usb key with the system, to provide cover in the event you are seen with the device (see below), and to provide a reason for any needed drivers on the machine.

      To send...

      1) write it in advance
      2) PGP it
      3) steganographically hide it
      4) take it to the cybercafe on a floppy/usb key
      5) upload it to a public place where everyone can see, so it is hard to track receipt
      6) Afterwards, out-of-band relay to a contact where to find it. If you relay ahead of time, a compromised contact could leak where to look for you. THIS IS THE HARDEST PART. It is effectively your key-exchange process.

      For receipt...

      1) Beforehand, find out where to look for what. THIS IS THE OTHER HARDEST PART. It is effectively your key-exchange process.
      2) at cybercafe, download uninteresting materials
      3) at home, de-steg and de-crypt
      4) store only if needed on key

      Regularly upload and download un-steg (no payload) and random steg (random payload) materials to defeat traffic analysis.

      If you have any time left over after all this, you can use it to be a dissident. However, you should regularly do other things such as get a job or have a family to provide a plausible reason for your existence.

      This wouldn't work in the People's Republics where sending and receiving encrypted messages is illegal.
      In this case, perhaps encrypting the message and putting the message inside a photograph using a stegnography program would work for a while.
      Eventually the police will learn about stegnographic programs and test all photos leaving the country on the web for any messages. There aren't that many commercial steg programs around.
      In brutal repressive regimes, the primary means of gathering information on the resistance is through informers. Eventually the police arrest everyone and offer them the deal of either spy on your neighbors and friends or rot in prison forever. The former East Germans were the masters of this. Almost everyone was forced to spy for the secret police. When the government fell the people first burned down the internal security headquarters and the files. The Israelis also use this technique to control Palestine. But they are far too heavy-handed to be effective.
      Assume that the best scientists and engineers will be working to spy on people. The police can easily arrest these people for imaginary crimes and then offer them special treatment in exchange for their willing co-operation. An excellent novel on how this works is The First Circle by Aleksandr Solzhenitsyn, writing about the slave labor camps for scientists in the Stalinist USSR.

      use different cybercafes in a random manner... don't use the same machine at any cybercafe.

      Bad idea.

      If you naively use the same cybercafe each time, the police will be able to watch the cybercafe, observing who is attending whenever the suspicious stuff happens, therefore you will be found quite easily.

      If you visit different cybercafes each time to avoid this, the police will simply watch a few local ones. You will show up at each one when the suspicious stuff happens. It takes a few more policemen, but you actually get caught quicker.

      Another solution is to use the same cybercafe each time, but do so during lunch hour, and use one near to a school or something. Basically, you want to have your visits coincide with a lot of people at the same time, and the same people each time.

      Of course at this point, the government will simply run a check on each observed person and find that you have a computer and internet connection at home, which means that there's no reason for you to be visiting a cybercafe.

      The problem is that the police can predict your visits. If you wait a few months in between suspicious activity and there is no CCTV, then you can be reasonably certain the police won't be able to find you, as long as you don't use the same one each time. Presumably the police don't have the resources to track who uses which cybercafe at any given moment.
