Zoom will enable waiting rooms by default to stop Zoombombing
- arkadiyt 6y ago> Starting April 5th, it will require passwords to enter calls via Meeting ID A meeting id with a password is semantically the same as a longer meeting id (or a meeting id with a character space larger than just digits). I wish they'd do that instead (make meeting ids longer) so I could continue to enter my company meetings with only a link but not have to worry about getting wardialed.
- detaro 6y agoyou can put the password in the link.
- bowmessage 6y agoExcept the search space is much, much, larger.
- Dylan16807 6y agoWhat is larger than what? With the most straightforward way for "meeting id with a password" and "longer meeting id" to be the same, both methods provide the exact same expansion in search space compared to the previous implementation, and they have the exact same search space as each other. (That method being: concatenate shortid and password to get longid)
- CPLX 6y agoHere’s an ignorant question. I see this comment all the time, that an ID and PIN is exactly the same as a longer ID, but is it actually true? I get the logic of it, but in a practical sense doesn’t it have the potential to be different? For example, if you have to enter a correct ID, wait, and then get prompted for a password, couldn’t that potentially slow down an attacker? Alternately, couldn’t a bunch of correct meeting ID’s followed by incorrect PINs present an opportunity to flag the ID as under attack, or give a prompt to a host that would spur inquiry, or something? Perhaps I’m wrong about this but it seems like there are some non trivial differences between the two.
- catalogia 6y agoThere is no reason you couldn't implement rate limiting under the "longer ID" scheme.
- CPLX 6y agoSure, but your rate limit would be for all conferences. The idea being by separating the conference number and PIN number you could limit the ability to attack a specific user ID more easily.
- Dylan16807 6y agoSo we have to look at what "attacking a specific ID" even means. With separate room numbers and PINs, it means you know the room number but not the PIN. Simple enough. But in the long-id scenario, that means you have part of the ID, but not all of the ID. That's pretty unlikely to happen. Instead, situations where someone would have leaked the room number will take one of two routes: either the person leaks the longer ID, and there is no attacking necessary, or the person realizes that the secret code needs to be secret, and nothing is leaked at all. Either way, attacks on a specific conference ID no longer happen.
- godelski 6y agoDon't we want the search space larger? That way it is harder to wardial? YouTube has 11 characters composed of [a-Z] and [0-9]. (26*2+10)^11 is a pretty big number. There's no reason it couldn't be longer.
- lmz 6y agoIt would also make it harder to dial by phone, if you need to do so.
- bowmessage 6y agoYep, exactly, I think it's beneficial and the right move.
- joe5150 6y agomeeting IDs need to be numbers to make it easy to join meetings by phone. no particular reason they can't be longer though.
- mjlee 6y agoYou will be able to enter with only a link, the url looks like: https://tenant.zoom.us/j/123123123?pwd=QlR0cXZkYXBDS0txYzJRRXhLS0lUQT08 https://tenant.zoom.us/j/123123123?pwd=QlR0cXZkYXBDS0txYzJRR... The password is an encoded version of the password set by the host.
- jdlyga 6y agoI work for a large multi-national media company, and we've been using BlueJeans for video conferencing for the last few years. It's been very reliable, but I haven't heard of very many others using BlueJeans. I'm curious if the security issues in Zoom vs its competitors more have to do with the amount of people using it and putting eyes on it.
- dehrmann 6y ago> I haven't heard of very many others using BlueJeans I'd think more eyes on Zoom right now will be better for it in the long run. Anecdotally, security aside, I've found Zoom to be about one step ahead of BlueJeans in pretty much every way.
- jsight 6y agoI've used BlueJeans extensively and I completely agree. I believe that it doesn't have a free tier though and this limits its adoption. I also do not believe that it claims to have E2E encryption or anything like that.
- e40 6y agoI was sent a link for them about a month ago. On Mojave the app kept crashing. I couldn't figure out how to join via the browser, so we switched to zoom.
- shmoogy 6y agoI found the quality and ease of use better with zoom, it's probably security through obscurity in the case of zoom vs BlueJeans though.
- avs733 6y agosame. we've had a few glitches here and there but overall highly reliable. The ability to do a meeting or do an event to prevent zoom bombing type issues is wonderful.
- arwineap 6y agoBluejeans seemed to be running into audio issues as we leaned on it heavier recently
- bretpiatt 6y agoExcept waiting rooms have a separate security problem https://citizenlab.ca/2020/04/move-fast-roll-your-own-crypto-a-quick-look-at-the-confidentiality-of-zoom-meetings/ https://citizenlab.ca/2020/04/move-fast-roll-your-own-crypto... HN thread https://news.ycombinator.com/item?id=22768494 https://news.ycombinator.com/item?id=22768494
- detaro 6y agoSo attackers have now ~24 hours to exploit this unpublished security issue before the second stage, required passwords, becomes active.
- prophesi 6y agoHopefully passwords are implemented in a way to slow down brute-forcing. I guarantee the majority of them will be a simple word or number sequence.
- kerng 6y agoThanks for highlighting this, i totally missed that there is waiting room security issue pending disclosure.
- gnicholas 6y agoTLDR: there’s a security issue that has been identified with regard to waiting rooms, and it has been reported to zoom. No further details will be provided until it’s fixed.
- mavsman 6y agoHopefully they do this for existing users as well. One of my fellow teachers' classes got bombed today even after we were all sent instructions about securing our meetings, enabling waiting rooms, etc. She didn't follow the recommendation because she "didn't think someone would join" because she hadn't posted the meeting link on social media. You have you protect your users that won't protect themselves.
- faitswulff 6y agoWaiting rooms don't help because you don't see any identifying information. My sister's call got zoombombed even with a moderated waiting room. They were trying to keep within their university's students, but they couldn't see the email addresses associated with the zoom user name in the waiting room, so a griefer got through.
- raverbashing 6y agoFor these cases required sign in might be best
- achow 6y agoSeems like User Interface design issue. At the minimum they could show anonymized email id: ab<..hidden..>gh@univname.com
- closeparen 6y agoZoom meetings created on my company's account can only be joined by people logged in through my company's SSO (unless the meeting is explicitly set to open). Universities typically have SSO, so this don't seem like a hard thing for them to implement.
- rdlecler1 6y agoWouldn’t it have been easier to present an option to the presenter once X number of people joined? So 3-5, no, but more then a dialog pops up asking the presenter if they’d like to have a waiting room.
- TACIXAT 6y agoI see some people running meetings who can barely find the chat. I'm not sure I trust them to manage a waiting room.
- godelski 6y agoGiving the benefit of doubt here, if you enter full screen mode chat opens in a different window and no longer gives you notifications. At least on linux. I honestly find this quite painful and rather surprising. I'm not sure why full screen and chat isn't equivalent to just maximizing the window (where the chat is on the right and users are above) with tabs to open and close chat (and users). New windows seems like a weird decision.
- Igelau 6y ago> a reasonable price to pay to keep people from being scarred by Zoombombing attacks That's right folks. The most traumatizing thing going on in the world right now is the two weeks where our video conferences got prank called with freaky porn. The scars will heal, and we will grow stronger. I'll see you all next Mar-Apr for Zoombombing Victim Awareness Week, where our distant gazes will still itch from the Five Nights at Freddie's Rule 34 pics that came screaming out of the aether to blitz our retinas. We will share many a fond remembrance of those dear fallen comrades of ours, whose ghosts shall tread with pixelated lips, ever-mumbling weary explanations to the kids.
- bartread 6y ago"Building development teams that include skeptics and realists, rather than just visionary idealists, could keep ensure products get safeguarded from abuse before rather than after a scandal occurs." On the face of it this sounds fair, but the problem is that being "sceptical" and "realistic" is far easier and requires much less effort than being "visionary"[1]. Too much of the former early on can really suck the life out of a team, increasing the risk that the product fails, or is simply never built. Safeguarding from abuse is much better achieved by systematic thinking and discipline (which are learned skills) rather than hiring "realists" who might simply turn out to be whiners and energy vampires. As much as Zoom is currently in the spotlight, and I can't say I'm overjoyed by a number of the issues I've read about (e.g., encryption keys being passed through Chinese servers?!??), many of them are the problems of success, and every successful company has or will experience their fair share of those. [1] I might also add that it's far easier to commentate and to critique than to do, eh, TechCrunch?
- Traster 6y agoI'm so tired of these types of comments. "The reason you have this issue is you're missing X", "Yeah but if we only had X we wouldn't have been able to do this at all!", "Yes, which is why I said you should have more X, not completely abandon everything but X". Let's be clear: The issues that Zoom is having were seen by other businesses in the same industry decades ago. At a time where every other messaging system in the world has been moving to end to end encryption - even facebook, Zoom is still lying about it to customers. It doesn't require a room full of sceptics to figure that out, it requires some sort of development process that involves a the tiniest bit of thought before rushing out a feature - a culture that is apparently consistently lacking in large parts of silicon valley. Btw, If you think that what we've seen over the last few years is that commentating on tech is an easy career to make a living at, you haven't been paying attention to the state of journalism.
- bartread 6y agoI really shouldn't rise to this but, OK, let's do this. The comment I quoted by TC was clearly intended as a general point with broad application across tech companies, not just Zoom. Now either TC meant that, in which I disagree as outlined in my previous comment, or they didn't, in which case it's sloppy phrasing and journalism. > Btw, If you think that what we've seen over the last few years is that commentating on tech is an easy career to make a living at, you haven't been paying attention to the state of journalism. I said it was easy to commentate or critique (it is, and it happens on HN all the time). I didn't say it was easy to make a career out of it nor, frankly, do I think it should be. There are far too many lazy, bottom-feeding media outlets in the world and not nearly enough good ones, so I will not shed a tear for the demise of the former. To address your specific points about Zoom: it is demonstrably false that "every other messaging system in the world has been moving to end to end encryption". Microsoft Teams does not implement end to end encryption for audio or video meetings because they can't: they support dialling into meetings using the plain old telephone system meaning that the back-end services become an endpoint and have to be able to decrypt traffic. Sure, Teams could do it for text chat (and it's even a suggestion on UserVoice: https://microsoftteams.uservoice.com/forums/555103-public/suggestions/33921943-end-to-end-encryption https://microsoftteams.uservoice.com/forums/555103-public/su...) but, as far as I'm aware, they don't even do that yet. Whether that's a big deal or not depends on your use case. That Zoom lacks E2E encryption is not the problem: that they claimed to implement E2E encryption when they don't is. Contrast with Microsoft, who don't claim E2E encryption for Teams and, as a result, there is no significant controversy. Some people and use cases do need E2E encryption but, for many, the trade-offs aren't yet worth it. As already highlighted you lose support for POTS, which in my experience is used pretty regularly: e.g., people on the move, or dialling in from outside the organisation. Another example: I suspect E2E encryption would make it difficult, even with modest numbers of participants to implement Zoom's gallery view because they'd have to send all encrypted streams in full to all participants, and clients would have to decrypt and decode all video streams. Even if it didn't prove overwhelming from a bandwidth perspective, it would eat CPU and drain battery life very quickly. Without E2E you can decrypt and multiplex on the server side then re-encode and re-encrypt to reduce bandwidth usage over the network and resource usage on clients. Of course, this isn't insurmountable: clients could send two encrypted streams, one hi-def, and one for gallery view, and the server could route them to clients as appropriate depending on their viewing preferences. Still, this probably isn't as efficient as dealing with it on the server side. (Obviously you might not care about gallery view, but it seems really popular for remote social gatherings.) It's all about trade-offs: for virtual pub with my friends, I don't really care about E2E encryption, but gallery view is really great. I don't even care about E2E encryption at work that much - certainly not enough to make it more difficult for people to dial in to meetings. But, as I say, none of this is the issue: the issue is the claims Zoom are making about their product.
- blackrock 6y agoI’ve used a lot of these tools, and I have to admit, Zoom is the best. As for the Zoombombing, I can’t say that I am surprised. All you really need is the URL. And all the other tools are like that too. Sure, you can require a separate passcode, but damn it, it’s like trying to figure out rocket science to enter the passcode. 1) you have to dial the number 2) you have to punch in the meeting ID 3) you have to punch in the passcode. 4) ERROR. You flipped it, and used the passcode for the meeting ID instead. Aargh.. frustration. 5) Forget about the passcode. Just let everyone in that has the meeting ID. And monitor if there’s someone unknown on the line.
- GordonS 6y ago> you have to dial the number It must have been at least a decade since I actually dialled into a video conference using a phone, on any conferencing platform - I always connect audio via my laptop or phone, which I use with a Bluetooth headset. I was actually having this conversation with a bunch of colleagues the other day, and every person in the call said the same thing, only difference was some used a USB headset, rather than Bluetooth.
- wodenokoto 6y agoMy understanding was that chats simply had too easy to guess names. Would this be solved by generating chat names through a cryptographic hash algorithm? I have google docs that are edible by anyone with the link and I’m kinda assuming that the link is as hard to guess as logging in with a password. Am I completely off and in dire need of reevaluating my personal web security?
- wcoenen 6y agoTechcrunch links seem to redirect through guce.advertising.com nowadays, which is blocked by my ad blocker. Also, according to redirect-checker.org it takes 5 requests before finally landing on the actual page. Seems excessive.
