But it’s literally the dumbest feature ever. There’s absolutely nothing preventing a user from pulling out their phone and taking a picture of any slide they want. Or having a camera recording the whole session out of view of their webcam. It is security theater at its peak.

It helps to prevent accidental sharing of confidential information.

hahaha nobody asked for this

You have no idea. Infosec in my company would ask for this.

> Some people might want it, but it doesn’t actually work Why do you think they can't prevent on-device screenshots/screen recording can't be prevented when you control the entire stack?

It's kind of like locks isn't it? It'll deter honest folks, but will it prevent screen capture when Teams is running in a VM? What about over VNC?

>VM

Yes, it will not be capturable. If the VM is not secure it will not display it.

>VNC

The VNC server will not be able to capture it.

There are two kinds of people in the world, those who completely misunderstand the value of friction, and those who depend on friction too heavily; GP clearly falls into the former group.

This feature provides value because it increases friction. It won't stop really determined and motivated users from leaking, but it'll make leaks, especially accidental leaks / those due to hacks, a lot less common.

The same applies to DRM, "security by obscurity", social media post editing / deletion, dark patterns, loss leaders, promotions and coupons, the list is endless.

If your user is a perfectly rational being with infinite time and infinite tech savviness, the proverbial "spherical cow", those features make 0 sense. Just like spherical cows, though, those users don't actually exist, and so friction matters.

That doesn't mean friction is infinite, though. It's too easy to overestimate it and fall into the trap of thinking that "users won't bother doing this, it doesn't matter if this combination of actions loses us money, it's too bothersome", and then get very surprised very quickly.

What about a camera? These aren't the use cases that really matters. What matters is the common case, and it's not about deterring honest folks. Honest folks aren't recording. This is really a lesson in security blind spots. The number of people that are trying to "get around this" assuming that's the issue. Edit: I'll make it simple. It will work because honest people aren't trying to get around it. But, they could…

> Honest folks aren't recording. Honest folks who want to be able to cover their ass later on are. Honest folks who are working for dishonest people and are planning to be a whistleblower are. Honest folks who have Recall on are. Possibly against their will if they haven't found out how to turn it off, or it's a work machine where they're not allowed to do so. Maybe they're not if Microsoft actually has enough interd…

One of the best rules I ever heard of was told to me by a cop here in Australia. She told me every time they unholster their firearm, they have to fill out about 3 pages of paperwork. I think that’s so genius.

Think about it - if you’re in a life or death situation, you won’t hesitate. Your gun is right there, and it’s there so you can use it. But if the situation doesn’t feel dangerous, the image of having to fill out 3 pages of paperwork justifying your actions is enough to make you hesitate. It’s weaponised bureaucracy. It’s like - there’s an ideal amount of friction for some actions to have. Pulling your gun out should have some friction to it. The choice should have weight.

I see this in just the same way. If the presenter doesn’t want their presentation recorded, there should be some friction to recording it anyway. It shouldn’t be impossible to record. But it shouldn’t be as easy as just taking a screenshot in windows.

Just like that cop with a gun, there should be the right amount of friction for recording a meeting against the wishes of the presenter. How many pages did the cop have to fill out? 3 pages. Not zero. Not 100 pages. How hard is it to record a meeting despite this protection? It’s doable - you need an hdmi capture card, or a camera out of shot, or something else. You probably need to set it all up before the meeting. And so on. It’s not impossible. But it’s not trivial either. That sounds just right to me.

Interesting how this will stop me from taking a picture with my mobile phone. The amount of effort people will go to, to make people's work more cumbersome. I am not screenshotting for espionage, I am screenshotting to accomplish my job.

And the phone’s what I’d be using to exfiltrate anyway. I’d only screenshot on the work device for work purposes .

100% this. If I have something juicy I want to show my wife about how they’re messing up our 401k’s, etc. I take a phone picture so that there’s no record of it happening on the official device.

Microsoft doing this is a huge waste of time other than catching the bottom 5% of people doing something like that.

I just want to add that my company has our stuff so locked down, that it’s easier for me to take a phone pic, transcribe the code with ChatGPT, fix the issue on my personal machine, then type it back into the work laptop for some issues. It’s absurd how businesses want to control everything to such a degree that 1) there are now these crazy, leaky workarounds, and 2) it’s to the detriment of people actually getting stuff done for the business.

Really? I didn't know it was possible to use DRM like WideVine for peer-to-peer video.

Teams is going through a central server and bouncing it out to participants, right? Not p2p.

I thought Teams was a reskin of Skype so whatever they used to do…

Very pleased this is coming. Once a week I hold a meeting with stakeholders to show my latest art works and I can hear them push the print screen button. Very annoying. I am trying to get these freshly minted but if is becomes public somebody has screenshotted them, the value plummets

RDP into computer that has meeting running and then screenshot from the external computer running RDP .

Yep, I already covered workarounds that would be possible with preplanning.

If you already do it regularly, then the preplanning is not a big barrier. You already know that you keep getting into situations where something is worth capturing.

HDMI capture with passthrough is $20.
