I'd guess that means that going forward security conscious people will be putting tape or covers over not only their cameras but also over their LEDs.
In high security settings the buildings have no windows or have fake windows to keep external laser signals out so that's not new. That's been true since about the time someone figured out you can reconstruct audio from the doppler of a laser reflected off windows.
- t-3 5y agoI already cover all the LEDs with electrical tape. Not for security, just because I hate unnecessary, over-bright blue lights shining everywhere.

- Ansil849 5y ago> or at least line of sight to the machine for this? Correct, and not just line of sight, but static line of sight. The potential scenario here is something like if there is a desk phone on someone's desk visible from the window that you want to monitor (and you also manage to successfully install custom firmware on the phone).
- suifbwish 5y agoHmm I was under the impression that this attack was for spying on airgapped systems. I have never heard of an airgapped phone, unless it’s just for internal purposes.
