Brazilian Breaks Secrecy of Brazil's E-Voting Machines With Van Eck Phreaking 157

Posted by timothy
from the old-ways-are-best dept.
After the report last week that Brazil's e-voting machines had withstood the scrutiny of a team of invited hackers, reader ateu writes with news that a hacker has shown that the Linux-based voting machines aren't perfectly safe; he was able to eavesdrop on them (translated from Portuguese) by means of Van Eck phreaking.

      Several ideas. Of course, use LCDs, as the CRT circuitry is the bad one. Shield the data connections so they don't radiate too much. Make the connections that transmit unencrypted data short. Use low-contrast fonts, so the sharp edges do not cause large voltage (and therefore EMI) spikes. Randomise the low bits of data shown on the screen, so you create obfuscating noise.

      Maybe you have to go as far as have a white noise transmitter to mask what you cannot elimiate. Plenty of room to move. Good on them for having such a contest - it flushed out all the 'Ooh, I didn't think of that' problems.

          With LCDs, if you can catch the digital signal, you can recover the data. But the signal is weaker (10s of volts, not thousands!), and higher frequency, so you need to be closer. The problem can be eliminated if you implement encryptio

      Not only that, but no device will ever be "perfectly safe." That phrase doesn't appear in TFA, it shouldn't have been put in the summary. If someone has to resort to Van Eck phreaking just to eavesdrop on polling because an open hacking competition yielded no vulnerabilities, it sounds pretty darn safe. Publicizing the vulnerability is still a good thing, maybe someone will be able to come up with a reasonable defense, but it doesn't sound like a showstopper to me.

        Instead it would take someone with significant knowledge and even serious funding to sway an election. Probably not just a someone, but even an organization.

        So the only way this could ever effect elections would be if there were an organization or group of conspiring individuals with significant monetary resources - AND for that group of people to feel that swaying an election would be in their interest - AND for that group of people to then be so immoral as to decide to do so.

      The NSA Tempest guidelines are probably sufficient.

      Of course, the requirements are potentially made weaker by what you're eavesdropping. Tempest is written assuming that eavesdropping is a problem, but that's not true with voting -- it's only a problem if you are then able to associate votes with individuals.

        What again is not a problem if one votes in densely populated area: emission from many voting machines would mix making it hard to differentiate a vote on a single machine.

      If you can couple the emissions at the location of the machine with the emissions from a particular user - say, their mobile phone's signature - then you can go back to forcing people to vote for X and make sure that they do, roughing them up as an example to the others you told to vote for X if you detected a vote for Y instead, without a need to plant something on them or leaving any trace.

      The voting machines were vulnerable to more than just eavesdropping, although eavesdropping was the official story from the government and also what most of the press was about.

      However, the voting machines have since been banned. The latest elections were held with paper and pencil. It's good that way.

      Now if people would only understand this ...

  • If we could somehow reach a level where e-voting was secure, think of the possibilities. The people might actually be heard! Now whether you think that is a good thing or not, I leave as an exercise for the reader. But what I'm trying to say is, imagine voting from your home computer on issues that matter to you. No longer will your representatives be able to hand wave about what their constituency wants, heck, you might not even need representatives.

      You just overlooked one small issue: voter turnout is already a problem in most democracies, as it is somewhat boring to vote for things your are not that interested in. If there were more elections, you would have to vote each week. Nobody is going to keep doing that, as most people do not see it as their job, and it is a process with very little positive feedback. So only the zealots and paid shills will remain, thus making your country run by big money and zealots with a nutty agenda. Not unlike the US i

    This is why I love the Canadian method: paper with circles, make an "X" in the circle you want, fold the paper and put it in the ballot box. Good luck hacking that on a large scale (what with scrutineers from multiple parties watching the election and the count and each other, plus the people there as independent scrutineers watching everyone else), and monitoring it (little cardboard voting booth on a table, voila, privacy. The only argument I could imagine is finger prints on the ballots, but you can wear gloves if you want.

      Yes, except I personally think that having to write a number is better. If somebody is unable to do that, it's probably for the better... (blind and other disabled people need an assistant anyway).

      You should consider that Brazil has almost 6 times the canadian population (180 million for Brazil and 30 for Canada) and that these voting machines have decreased the time it takes to display results greatly. We have results with 90%+ machines accounted in less than 12 hours. So far this hack has been the most significant issue and it can be prevented now that the information is public.

    Why does the electronic voting machine have to be a touch screen? Why not a list of the options with buttons with an LED in them that light up when you press the button? The list could be on a separate display next to the buttons but nothing changes therefore the 'van eck phreaker' would only get the data on the screen, not the option picked... but I have no knowledge of this sort of stuff.

    Maybe some places do that, but where I live we do vote by mail.

      North Carolina used to use a system like that, a long time ago. (I remember my parents taking me with them when they voted, I got to help my mom submit her ballot, it must have been back in '96). However, the main draw of e-voting is accessibility: the ability to have high contrast and/or large size fonts, computer reading the ballot out loud, etc. This isn't possible with the equipment you describe.

      because here in brasil we don't have voting districts, so in state and federal elections, a candidate from santos (a sea-side city in sao paulo state, some 80 km east of the state capital) can receive votes from people in ribeirão preto (a city 400 km west of the capital). this makes the candidate lists for federal and state deputies something in the thousands.

      our voting system uses numbers. each party is assigned a number (ex. PP=11, PDT=12, PT=13, etc.) and every candidate have a number prefixed with

    While in principle it is a good method for snooping a single monitor, it would take a ton of disentangling signals to read every monitor consistently at a polling place from any distance. It is not a practical way to screw with an election, considering that any party willing to snoop this aggressively is probably willing to do a lot more than just snoop.

    Frankly, it shows just how effective Brazil's security measures are that hackers have to go this deep into the playbook to get even one sort of result.
