Hidden wallet discovered — hardware wallet (2022)

Blocked

Case description

A July 2022 incident in Spain recorded in the Lopp physical attacks database involved a Bitcoin holder forced to transfer funds at gunpoint by attackers who had identified him through a local crypto community group. The victim attempted to use a decoy wallet strategy but the attackers were sufficiently sophisticated to demand verification of on-chain balances before accepting the transfer. The planned defense—a low-balance visible wallet over a high-balance hidden wallet—was defeated by on-chain verification.
