# Mersenne Twister 32 bit seeding => bx consumption pattern => BIP32 master key This is a special and unusual way of generating keys with BIP32, but without derivations. See [libbitcoin-explorer bx-ec-new](https://github.com/libbitcoin/libbitcoin-explorer/wiki/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. ## Observed Usage * We only investigated usage with Bitcoin. * Compressed and uncompressed pubkeys ## Writeups * See [research update #1](https://milksad.info/posts/research-update-1/).
