Microsoft is rolling out a new security feature for Teams that will prevent users from taking screenshots during meetings. This update, set for July 2025, applies to desktop, mobile, and web versions. If a platform doesn’t support this protection, meetings will default to audio-only mode.
Key Limitations:
- ❌ Does not prevent external device photography (e.g., phone cameras).
- ❌ Unclear if enabled by default or configurable by admins.

You Should Know: How to Bypass & Secure Teams Meetings
1. Detecting Screenshot Attempts (Windows/Linux)
Windows: Check running processes for screenshot tools
Get-Process | Where-Object { $_.ProcessName -match "snipping|snip|lightshot|greenshot" }
Linux: Monitor for screenshot CLI tools
ps aux | grep -E "scrot|gnome-screenshot|import"
2. Enforcing Screen Recording Restrictions
Linux: Disable screencast permissions via DBus (GNOME) gsettings set org.gnome.desktop.media-handling disable-screencast true Windows: Disable screen recording via Group Policy gpedit.msc > Computer Config > Admin Templates > Windows Components > Meeting Capture > "Prevent meeting capture"
- Virtual Machine Workaround (As Mentioned in Comments)
Use VirtualBox to capture host screen VBoxManage controlvm "VM_Name" screenshotpng "/path/screenshot.png"
4. HDMI Capture Detection (Hardware-Level)
Check connected capture devices (Windows)
Get-PnpDevice | Where-Object { $_.FriendlyName -match "capture|video" }
5. Teams Admin Controls (PowerShell)
Force disable meeting recording (if allowed by org) Set-CsTeamsMeetingPolicy -Identity Global -AllowCloudRecording $false
What Undercode Say
Microsoft’s move is a partial security improvement but easily bypassed via:
– Virtual machines (host-level capture)
– HDMI recorders (hardware-based)
– External cameras (analog loophole)
For true security, combine this with:
- Endpoint DLP (e.g., Microsoft Purview)
- Watermarking (dynamic meeting IDs)
- AI monitoring (unusual screen activity)
Prediction
This feature will reduce casual leaks but not stop determined attackers. Future updates may integrate AI-based screenshot detection (e.g., analyzing shared images for Teams meeting UI patterns).
Expected Output:
- Security teams should prepare for bypass attempts.
- Admins must enforce DLP policies alongside this feature.
- Users should avoid sharing sensitive data even with protections.
