No, screen sharing after ending a call is a “feature, not a bug”. Imagine our surprise when, after a few seconds of Googling the issue and thinking about contacting Microsoft, we came across this thread. We thought that we had stumbled upon a serious security flaw. In some areas, a competitor could do seriously damage with how much information they are able to see. Had a cybercriminal participated in a conversation like this, they would have had a field day with the info obtained. Spreadsheets with sensitive financial data, inbox contents, private messages on Facebook, all of them will be seen by the other person. If the person who had hosted the session does not notice the tiny warning at the top, they will continue sharing whatever they’re doing on the screen. The people at the other end of the line will still see what’s happening there.
Once the person who started screen-sharing hangs up, the desktop-sharing function will continue. If you do a Skype for Business call with “screen-sharing” turned on, be prepared to share more than what you wanted.
It was not related to hacking and other cyber-attacks but a pure “feature”, whose purpose and value we haven’t yet been able to decipher. This week, we discovered a serious security risk and privacy breach with the Skype for Business app. Sometimes, ubiquitous, extremely popular services release some features that truly boggle the mind. Sometimes, it becomes obvious that tools and education alone won’t keep users truly safe online, nor will they enforce their privacy.
Update It is now possible to share system audio in Live Events.Here at Heimdal Security, we spread our time between providing security tools to prevent serious attacks like ransomware or next-gen malware and providing the education necessary to keep personal data safe across various platforms and devices. Microsoft posted in the uservoice that this feature is In testing and “hope to release soon”. There is an uservoice request to get this working in Live Events and Microsoft is working on it. On Computer A you play the video with audio content and on Computer B you are signed in as a presenter in Live Events, audio and video from come from Computer A via USB. Connect HDMI from Computer A to the Magewell device and the Magewell USB output to Computer B. With Live Events you might want to share audio too but currently that is not possible, when sharing in Live Events we don’t get the option to share audio.Īn solution you could use there is two computers, Computer A and Computer B. System audio shared in meeting will be recorded too. If you record your meeting it will be saved to Microsoft Stream. But in this uservoice request Microsft updated that it is expected to be released “this quarter”, posted April 11.
If you are running Teams on a Mac it is not possible to share system audio when sharing desktop.
Now you are ready to share your system audio in a meeting. If not you can click on the small arrow and select another device. Make sure that the device showing here is the same as you had selected in Teams. In your systray left click on the speaker icon.
In Teams you have a couple of different ways to select you audio device, one ways is in your meeting select more actions ( …) and then select Show device settings.
If you don’t have the same audio device selected in Teams and in Windows you will see this error. So if you hear the audio from other participants in your headphones you have to make sure that your Windows system sound is played to that device too. To fix this you have to make sure that your Windows audio device is the same as your audio device in Teams. You might get an error that says “Switch speakers to include audio”. You can also do this if you forgot to share system audio when you started to share your desktop. Then move your mouse to the top of your screen and a menu should appear, select Include system audio by clicking on the button. Click on the Share button and then select to share a Desktop or a Window. If you don’t have the checkbox you can start sharing your desktop or application in your Teams meeting. You can’t share a PowerPoint file when Include system audio is selected. When you sharing your desktop select the sharing button and then check the checkbox Include system audio and then select a Desktop or a Window to share. To share system audio you can do it when you start sharing your desktop or after you already have shared it. It is possible to include system audio, if you have the correct settings. When you are showing a video or something else with audio from your computer into a meeting in Teams you want the meeting participants to be able to hear the same audio as you hear. This is an updated article since Microsoft changed the layout of this feature.
