Mobile (in)security: Avoid use mobile devices, consider using a Faraday Bag. The GSM network is highly traceable; even a turned-off cell phone is no longer safe.
A Faraday bag is a simple, portable enclosure that blocks electromagnetic fields, preventing electronic devices inside from sending or receiving signals. It's useful for protecting your devices from tracking, hacking, or unwanted communication. Below is a step-by-step guide to making your own Faraday bag.
- Aluminum foil (heavy-duty preferred)
- Alternative: Copper or nickel mesh, which offers enhanced shielding and durability.
- Alternative: Conductive metallic fabric or Faraday fabric for a more durable and flexible bag.
- Plastic Ziploc bag or other durable, sealable plastic bag
- Alternative: Mylar bag or any other airtight, non-conductive pouch for better sealing.
- Duct tape or conductive tape (for reinforcement and sealing edges)
- Alternative: Aluminum or copper tape for a more secure, conductive seal.
- Scissors (for cutting foil or fabric)
- Optional: Velcro strips or zip ties (for creating a reusable closure)
| Technology | Decentralization | Anonymity | Resilience | Accessibility | Speed | Challenges |
|---|---|---|---|---|---|---|
| GSM (Traditional Mobile Networks) | Low | Low | Low (easily surveilled, controlled) | High (widely accessible) | High | Susceptible to government surveillance and control, requires centralized infrastructure. |
| Private GSM Networks | Medium | Medium | Medium (localized, difficult to monitor) | Low (requires setup and maintenance) | High | Limited range, regulatory challenges, expensive setup. |
| Satellite Phones | Medium | Medium | Medium (can bypass local networks but still traceable) | Low (expensive, regulatory restrictions in some areas) | Medium | High cost, signal blockage issues, legal restrictions in certain countries. |
| LoRa Networks | High | Medium | High (independent of traditional infrastructure) | Low (requires specific hardware) | Low | Limited bandwidth, short range without mesh network, specialized hardware needed. |
| Mesh Networks | High | Medium | High (difficult to censor/control) | Low to Medium (dependent on community adoption) | Medium | Requires widespread adoption, potential for limited range without sufficient nodes. |
| Tor (The Onion Router) | High | High | Medium (can bypass censorship but still dependent on the Internet) | Medium (requires technical knowledge) | Low | Weak end point, slow speeds, requires Internet access, subject to state attempts at blocking. |
| Amateur Radio (Ham Radio) | High | Low to Medium | High (operates independently of state networks) | Low (requires license, specialized equipment) | Low to Medium | Requires technical knowledge, legal restrictions, potential for interference. |
For intermediate security, it's no military-grade security.
- Consider using a Faraday Bag.
- Be aware of the physical security of your device; if it's seized, immediate access may be possible with Cellebrite despite all protections.
- Keep your device's operating system and apps up to date to mitigate known vulnerabilities.
- Use full-disk encryption to protect data at rest. Both iOS and Android offer this feature.
- Enable a strong, alphanumeric password rather than a simple PIN or pattern.
- Consider using a secondary device for sensitive communication that you do not use for other activities.
- Consider using encrypted messaging apps like Session, Simplex or Signal, which offer end-to-end encryption.
- Use a VPN (Virtual Private Network) to obscure your online activities from ISPs and other intermediaries. Your data could be collect by data brokers and selled to government.
- Disable Wi-Fi, Bluetooth, and GPS when not in use to reduce tracking risks.
- Regularly check app permissions to ensure no unauthorized access to your location or microphe.
Cellebrite's UFED (Universal Forensic Extraction Device) is a powerful tool used by governments to extract data from mobile devices bypassing security features. Understanding the vulnerabilities it exploits can help in securing your devices against such intrusions.

The GSM network is highly traceable, even a turned-off cell phone is no longer safe.
- Avoid Reusing SIM Cards or Devices:
- Always use a new SIM card and a new device for each communication session. This prevents the possibility of linking different activities together through the same hardware or SIM.
- Avoid Carrying Different Devices Together:
- Never carry your burner phone along with your primary phone or other devices. If you do, the devices can be correlated through proximity tracking or geolocation data.
- Avoid Creating Physical Associations Between Different Devices:
- Use different locations when using different devices. Do not use a burner phone in places you frequently visit or where your primary phone is usually active. This prevents linking the burner to your personal identity.
- Avoid Calling or Being Called by the Same Contacts on Different Devices:
- Make sure that your burner phone is used to contact individuals who do not have your primary phone number. This helps avoid linking different devices through shared contacts.
- Use Cash or Anonymous Payment Methods:
- Purchase burner phones and SIM cards with cash or through anonymous payment methods. Avoid using credit cards or any payment method that can be traced back to you.
- Buy Devices Far from Home:
- Purchase your burner phone and SIM card from locations far from where you live or frequently visit. Avoid places with surveillance cameras that could capture your purchase.
- Disable GPS and Location Services:
- Turn off all location services, GPS, and Wi-Fi on the burner phone to reduce the risk of location tracking. If possible, disable or remove the GPS hardware entirely.
- Avoid Storing Personal Information:
- Do not store any personal information, contacts, or messages on the burner phone. Use it strictly for the intended temporary purpose and dispose of it afterward.
- Use Encrypted Communication Apps:
- When communicating through a burner phone, use encrypted messaging apps like Signal, Session, SimpleX, or Telegram. Be cautious as some apps may still leak metadata.
- Be Aware of IMSI Catchers:
- Avoid areas known to have heavy surveillance or where IMSI catchers (devices that mimic cell towers to intercept communications) might be deployed. These can be used to track and intercept burner phone communications.
- Practice Good Operational Security (OpSec):
- Develop and maintain strict OpSec habits, such as only turning on the burner phone when necessary, and never using it at home or work. Dispose of the phone after use in a secure manner, such as by dismantling and destroying it.
- Remove or Disable Microphones and Cameras:
- Consider physically removing or disabling the phone’s microphones and cameras to prevent audio and video surveillance. Many phones have multiple microphones, often one near the speaker and one near the bottom of the device. These components can be removed or disabled, but doing so may affect the phone's functionality.
- Dispose of the Phone Securely:
- After the phone has served its purpose, dispose of it in a way that ensures it cannot be traced back to you. This may involve physically destroying the device or disposing of it in a location far from where you live or work.

Cryptophones are specialized mobile devices designed to provide secure communication through encryption. One notable example is the Encrochat case, where criminals used highly encrypted phones.
https://www.vice.com/en/tag/encrypted-phones/
Tips and Recommendations:
- Choose cryptophones that have been vetted by reputable cybersecurity experts for potential backdoors or vulnerabilities.
- Be cautious of the supply chain when purchasing a cryptophone; only buy from trusted vendors.
- Regularly update the cryptophone's software to protect against newly discovered vulnerabilities.
- Consider using separate devices for sensitive communication and daily tasks to minimize exposure.
- Always assume that encrypted communication could eventually be decrypted, so limit the sharing of highly sensitive information.
