I've always thought Twitch streamers were opening up an attack vector through this exact method.
Cool to see someone follow through with it. Any streamers out there should figure out a way of avoiding keypress bleed or muting their mics when typing sensitive info (e.g. passwords).
- nmstoker 8y agoYes, countermeasures, such as playing other sounds around those frequencies and/or filtering the microphone at those frequencies would be interesting to explore. Filtering the mic seems the less annoying from a user perspective!
- drankula3 8y agoMost streamers, myself included, use a filter called a noise gate, which requires the volume of the mic reach a certain threshold before being broadcast. This filters out the majority of background noise on the stream.
