YubiKey Cloning Impractical Risk
- YubiKey vulnerability to cloning requires physical key theft and credentials, making it impractical for most users.
- Despite being unpatchable, it's a low-likelihood threat mainly relevant to nation-state adversaries.
Use Verified Flipper Firmwares Safely
- Use unofficial Flipper Zero firmwares for unlocked, enhanced features but beware of legal and regulatory restrictions.
- Verify firmware integrity by downloading release tarballs and checksums rather than updating directly via website tools.
