Mersenne Twister 32 bit seeding => bx consumption pattern => direct elliptic curve key
This is a special and unusual way of generating keys directly from the PRNG output without any BIP39 or BIP32 hashing or derivations.
See libbitcoin-explorer bx-ec-new for details.
Victims could have used a combination of bx seed
and bx ec-new
to generate weak keys in this range.
