bs58-86npm

Package [email protected] reproduces the name, README, repository URL (cryptocoinjs/bs58), and exported API of the widely-used bs58 base58 encoding library (>10M downloads/week). The only functional code in src/cjs/index.cjs is require('base62-86x')(ALPHABET) — instead of depending on the real base-x package that genuine bs58 uses, this package pulls in base62-86x (declared as ^5.0.4 in package.json dependencies), an unrelated package controlled by a different publisher. All actual base-x implementation runs out of base62-86x, so any developer who installs bs58-86 thinking it is bs58 ends up executing whatever base62-86x ships, at require time. This is the typosquat-plus-dependency-redirect shape: the lure package is a thin shim whose only effect on the installer is to pull in and execute the redirected dependency.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
