Big differnece. There was no software installable on "dumb" telephones. They could not be programmed remotely to change functionality to listening without ringing. That would have required an easily detectable hardware change. Smart devices on the other hand are always vulnerable to this possibility.
- smokinjuan 11y agoGranted it took a bit more doing than nowadays, but the old phones had a mechanical ringer that is basically a microphone. No rewiring necessary. http://www.bugsweep.com/instrument.html http://www.bugsweep.com/instrument.html and https://www.schneier.com/blog/archives/2010/01/eavesdropping_i.html https://www.schneier.com/blog/archives/2010/01/eavesdropping...
