Wallets generated by Libbitcoin Explorer's `bx seed` command (versions 3.0.0–3.6.0). Used a Mersenne Twister with a 32-bit seed (~4 billion possible wallets) — fully brute-forceable. Researchers swept ~$1M from these wallets in 2023. The Pi monitors the 313K affected addresses published by milksad.info. milksad.info Source: position 288598 in milksad.info's published affected-address list Address form: `p2wpkh`

Anyone using a private key in 1..10,000 (e.g. `k = 1`, `2`, …) shares it with anyone who has ever downloaded a Bitcoin puzzle list. These are the famous "puzzle addresses" — funds sent here are typically swept within seconds by automated bots. Private key: `k = 1` Address form: `p2wpkh`
