Here’s how to protect your electronics and personal privacy from electronic surveillance and EMP-like threats:

🛡️ 1. Faraday Cages and Shielding

• What they do: Block electromagnetic fields (EMF), including surveillance signals (e.g., RF, cellular, Wi-Fi).
• How to use:
  • Store sensitive devices in Faraday bags (available commercially).
  • Build DIY Faraday cages using metal mesh or conductive containers lined with insulation.
  • Harden critical infrastructure (home routers, laptops, radios) in shielded enclosures.

🔒 2. Air-Gapping Critical Devices

• What it means: Keep some devices completely disconnected from the internet or wireless networks.
• When to use:
  • For storing sensitive documents, encryption keys, or forensic tools.
  • For high-trust systems that don’t need to be online.

📡 3. Radio Frequency (RF) Monitoring

• Why it matters: Surveillance tools may transmit data using hidden radios (e.g., GSM bugs, Wi-Fi sniffers).
• Tools to consider:
  • RF detectors (e.g., K18 RF Detector) to find hidden transmitters.
  • Software-defined radios (SDRs) like HackRF or RTL-SDR for advanced spectrum analysis.

🧯 4. EMP-Proofing Critical Systems (for resilience)

• Protective measures:
  • Use surge protectors with high Joule ratings.
  • Store backups and critical devices in shielded enclosures or metal safes.
  • Maintain offline backups in hardened storage.
  • Use non-digital alternatives for fail-safes (e.g., paper maps, analog radios).

🔐 5. Counter-Surveillance Best Practices

• Cyber hygiene:
  • Use privacy-focused OS like Tails or Qubes OS.
  • Communicate via end-to-end encrypted platforms (e.g., Signal).
  • Block microphones/cameras with hardware switches or covers.
  • Use ProtonMail or Tutanota for secure email.
• Physical hygiene:
  • Regularly audit surroundings for unusual devices or signals.
  • Use hardware firewalls or VPN routers to monitor inbound/outbound data.
