Canadian spies illegally tracked travellers using free airport Wifi

A new Snowden leak reported on the CBC reveals that secretive Canadian spy-agency CSEC was illegally spying on Canadians by collecting information from the free Wifi service in major airports and cross-referencing it with intercepted information from Wifi at cafes, libraries and other public places in Canada.

The agency is prohibited from spying on Canadians without a warrant, but it captured data on all travellers in a Canadian airport, ensuring that it captured an enormous amount of sensitive information about Canadians. It claims that because it did not "target" Canadians (that is, it spied on everyone, regardless of nationality), they somehow weren't "spying" on Canadians.

The CBC article features a brilliant and incandescent Ron Diebert (who runs the Citizenlab centre at the University of Toronto and wrote one of the best books on Internet surveillance, Black Code), and an equally outraged Ann Cavoukian, the Ontario privacy commissioner, who is one of the most savvy privacy advocates in any government.

Indeed, the spy agency boasts in its leaked document that, in an apparently separate pilot project, it obtained access to two communications systems with more than 300,000 users, and was then able to "sweep" an entire mid-sized Canadian city to pinpoint a specific imaginary target in a fictional kidnapping.

The document dated May 2012 is a 27-page power-point presentation by CSEC describing its airport tracking operation.

While the document was in the trove of secret NSA files retrieved by Snowden, it bears CSEC's logo and clearly originated with the Canadian spy service.

    Every time I've gone through Pearson in the last few years, I've been kept waiting for hours before my flight finally boarded, Then there are the rude US Immigration people and the overpriced food once you get through security. I tried bringing my own food, but US Homeland Security decided it looked tasty so they confiscated it for their lunch.

    The only saving grace was the free WiFi, so now I find that they are tracking me when I read boingboing and other sites. Or sending emails to my mother. "Yes we managed to get through security, I retrieved my shoes, now our flight is delayed for four hours."

    I guess the way of the future is free Wifi and being spied upon, or pay for WiFi and maybe you will be spied upon.

  2. It's just as easy to passively* track you with paid wifi, too.

    (* without cooperation from the wifi provider)

  3. When using free wifi, I usually use a ssh tunnel proxy for my browsing. Not sure how much it helps, but it gives me the warm-n-fuzzies...

  4. For the last X years, I've been using a VPN service whenever I'm not on my home network (and sometimes even then). Having been the person running kismet (or wireshark or any variation thereof) to grab data out of the sky just to see what's floating around, I now see everyone else on the wireless network as a potential attacker and I try to secure my communications accordingly.
