Show HN: Browser-Based Tempest – Transmitting VHF Morse via Monitor EMI Leakage
Description and use
Browser-Based Tempest transmits VHF Morse code signals via monitor electromagnetic interference leakage directly from a web browser, making it valuable for TEMPEST attack research and covert channel experimentation. Adoption requires manually inspecting the source code, dependencies, and license terms, then testing compatibility with your target display hardware. The project sits at medium production readiness — suitable for prototypes and internal research workflows, but needs verification of maintenance activity and security implications before production use.
Use in a workflow
Show HN: Browser-Based Tempest – Transmitting VHF Morse via Monitor EMI Leakage may be useful when its README and activity match a concrete workflow.
Limitations and review notes
Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.
