How to setup a Bitcoin Air-Gap Computer?
DON'T.
You will almost certainly screw
yourself out of your Bitcoin.
Use a hardware wallet instead.
Computers (incl. Raspberry Pi and other single board linux computers) were not designed to hold secrets, here is just a short list of attacks:
- SeedSigner Rasperry Pi Evil Maid Persistant Seed Storage
- Rasperry Pi Data Extraction LoRA, With No Radio
- Cold Boot Attacks
- The Chilling Reality of Cold Boot Attacks
- Lenovo X1 Carbon Bitlocker Key Sniffing any% Speedrun (42.9 seconds)
- Critical vulnerability affecting most Linux distros allows for bootkits
- Academics turn RAM into Wi-Fi cards to steal data from air-gapped systems
- Sniffing Keystrokes With Lasers/Voltmeters
- Generating Covert Wi-Fi Signals from Air-Gapped Computers
- Flaws in self-encrypting SSDs let attackers bypass disk encryption
- NSA TEMPEST Attack can remotely view your computer and cell phone screen using radio waves!
- LED-it-Go - exfiltrate data from air-gapped systems via an HDD's activity LED
- USBee - force a USB connector's data bus give out electromagnetic emissions that can be used to exfiltrate data
- AirHopper - use the local GPU card to emit electromagnetic signals to a nearby mobile phone, also used to steal data
- Fansmitter - steal data from air-gapped PCs using sounds emanated by a computer's GPU fan
- DiskFiltration - use controlled read/write HDD operations to steal data via sound waves
- BitWhisper - exfiltrate data from non-networked computers using heat emanations
- Unnamed attack - uses flatbed scanners to relay commands to malware infested PCs or to exfiltrate data from compromised systems
- GSMem - steal data from air-gapped systems using GSM cellular frequencies
- xLED - use router or switch LEDs to exfiltrate data
- aIR-Jumper - use a security camera's infrared capabilities to steal data from air-gapped networks
- HVACKer - use HVAC systems to control malware on air-gapped systems
- MAGNETO & ODINI - steal data from Faraday cage-protected systems
- MOSQUITO - steal data from PCs using attached speakers and headphones
- PowerHammer - steal data from air-gapped systems using power lines
- CTRL-ALT-LED - steal data from air-gapped systems using keyboard LEDs
- BRIGHTNESS - steal data from air-gapped systems using screen brightness variations
- AiR-ViBeR - steal data using a computer's fan vibrations
- POWER-SUPPLaY - steal data by turning the power supply into a speaker
- Acoustic attack - steals data from keystrokes with 95% accuracy
- list wip, i'm lazy.
