If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The package name @zzzcrypto/bitcoin-lib and its README present it as a drop-in for bitcoinjs-lib, and the code attempts require('bitcoinjs-lib') to transparently proxy the real library's API when present so callers observe normal behavior; the internal identifier in the exfil payload is @wethenorth12/bitcoin-lib, and identifier names in the harvester are scrambled (kffr, xqyv, qzph, _h).
