Zoom's Encryption Is 'Not Suited for Secrets' and Has Surprising Links To China, Researchers Discover (theintercept.com) 61

Posted by msmash from the zooming-in dept.
Meetings on Zoom, the increasingly popular video conferencing service, are encrypted using an algorithm with serious, well-known weaknesses, and sometimes using keys issued by servers in China, even when meeting participants are all in North America, according to researchers at the University of Toronto. From a report: The researchers also found that Zoom protects video and audio content using a home-grown encryption scheme, that there is a vulnerability in Zoom's "waiting room" feature, and that Zoom appears to have at least 700 employees in China spread across three subsidiaries. They conclude, in a report for the university's Citizen Lab -- widely followed in information security circles -- that Zoom's service is "not suited for secrets" and that it may be legally obligated to disclose encryption keys to Chinese authorities and "responsive to pressure" from them.

      Zoom provides value to people, and the security issues are obvious to any minimally knowledgeable person. They are going to have features that generate profits, and those features are going to prioritize Zoom and paying customers, not the end user. Even the paying end user is not going to be a priority, as that is not the business model. Obviously no real business should use Zoom, any more than they would use so,ec random person on the street to handle a confidential letter, there are situations where Zoom

        "Zoom isn't great, but I'm sure they're okay. Now let me complain about a totally different company!!!"

        Zoom lied. They lied about their encryption, about selling your information, and lots of other things. This is not something that "any minimally knowledgeable person" can figure out.

        I sometimes use telnet to debug things. That's fine; I understand the risks. But if I use ssh I don't expect those same risks, so an ssh which disables all encryption would be a problem.

    China can infect the entire planet with a virus and no one will do anything to them for it...

    I wonder if our species has become basically one giant Stockholm experiment. Everyone and every government has failed... and not just in some small way. Catastrophic failure from all governments. Only Australia had the brass to do the right thing. With WHO becoming a parrot for China, China actively suppressing information and especially their involvement.

    If the world does not sink China for this, China will know how far it can go with things... and it can already go too far. As things go, China has no problem letting its citizens die to make sure its economy stays healthy, spread misinformation, control information, murder/imprison dissenters, and when China has all that cash to flash against all the money starving nations that have murdered their economies in knee jerk response... well we will see how things shake out... won't we?

          Slashdot isn't writing the Zoom hate articles though. It's merely pointing them out.

          If Slashdot stopped pointing them out, that isn't going to stop people from writing about all the lax privacy/security problems with Zoom's product.

      Most of the issues raised so far are exactly in line with your view... largely non-issues being hyped because you can get press now that you're targetting today's cool thing.

      The "encryption keys came from servers in China" one ... is more serious.

      (the "poor use of encryption" one is ... back to fear mongering. Everything that deals with connections that can drop will have to use block an EBC-like mode with similar issues. Otherwise a lossed frame loses much more.)

      Also, most of these stories talk about the free version of Zoom. There is a paid version of Zoom that has contractual agreements to do end-to-end encryption with your own key/passcode management in North America, without Chinese datacenter involvement.

      You're basically blaming the car manufacturer for not giving you the car when you just took a test drive.

      neither tfa nor the reference it references really prove they do encryption themselves. it seems more like a bad implementation of proven protocols and overall a weak design. that's far from "rolling their own crypto", that's actually the case with most vulnerabilities. granted, the design is weak, just as weak as much of the conclusion (the research seems proper, though, just someone felt the urge to drum it up).

    • Hmm, you trust OSS encryption? I have a bridge to sell you.

This includes my employer, who jumped on it on two feet to soon have to put up security measures to contain potential risks. My question is: there are lots of other solutions that have been vetted more, and yet... When possible I prefer to use Meet, not because it's better (although the automated caption makes is fantastic), but because I "trust" Google more than I trust Zoom. And that should tell you something about the reputation of Zoom.

      Where Zoom works better than a lot of other offerings is when you are Video Conferencing with more than 5 people. Some of our team meetings have 15+ people, all with video. Most other solutions get bogged down and you start seeing a lot of dropped frames. If you typically have videoconference meetings with 5 or less people, then other solutions may be a better fit.

      But, yes, Zoom obviously needs to work on the product security.

      I think Zoom's main selling point is large numbers of people already using it. People suggest the thing they have had suggested to them, and Zoom does work reasonably well.

    More seriously, if you think that a teleconferencing service is suitable for discussing secrets, you have no business handling secrets. You, and anyone who handed you a secret, needs to be slapped. Derisively, with a back hand.

  • I took a NSA sponsored encryption course in 1990. 30 years ago. Think you have a really good encryption scheme? Often those methods are used for home work they're so trivial to break. It's very likely so is this. Just use AES. That's what it's there for. It's free.
