A hardware wallet is supposed to be the boring, safe answer to crypto security. Your keys live on a small device that never touches the internet, so nothing online can reach them. On October 9, 2026, that assumption failed. Wallet owners in Southeast Asia watched their balances drain, and as of October 15, 2026, on-chain researchers estimate the losses at somewhere between $86 million and $93 million across more than 300 wallets. Now crypto holders everywhere are asking whether a Faraday bag for crypto wallets could stop the next attack like it. Nobody cracked a password or clicked a bad [...]

A common misconception is that a Faraday cage provides full blockage or attenuation; this is not true. The reception or transmission of radio waves, a form of electromagnetic radiation, to or from an antenna within a Faraday cage is heavily attenuated or blocked by the cage. However, a Faraday cage has varied attenuation depending on wave form, frequency or distance from receiver/transmitter, and receiver/transmitter power. Near-field high-powered frequency transmissions like HF RFID are more likely to penetrate it. Solid steel cages generally provide better attenuation than mesh cages. [From Wikipedia] Attenuation is the key information that informs the user [...]
