As an IT professional, I say this passionately: fuck computers.

Summary:

- Commodity PCs' built-in sensors, such as microphones, unintentionally capture electromagnetic side-channel leakage from ongoing computation.
- This leakage can be conveyed through supposedly-benign channels like audio recordings and Voice-over-IP applications.
- Remote and passive analysis of these channels allows for physical side-channel attacks on computation without physical proximity or the ability to run code on the target.
- The captured computation-dependent leakage can be used to steal secret keys, detect web pages being loaded, and identify hidden opponents in online games.
