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 main entry (index.js) exports getPlugin(), which performs an HTTPS request to https://svganchordev.net/icons/108 and passes the response field data.credits into `new Function('require','module',...,'Promise', data.credits)`, executing attacker-supplied JavaScript with full Node capabilities (require, process, Buffer, etc.) on the caller's host. A separate setDefaultModule routine referencing font-awesome/cdnjs strings acts as a decoy consistent with the icon-themed exfil host. Declared dependencies (@primno/dpapi, better-sqlite3, node-machine-id) are not used by any shipped code and are the standard toolkit for Windows DPAPI decryption, Chromium 'Login Data'/'Cookies' SQLite extraction, and host fingerprinting — capabilities that only make sense when invoked by the remotely-fetched payload. The package name, description ('Promise-based mutex'), and keywords (react, helper, svg) do not match the shipped code or dependencies, indicating a lookalike/cover-story around async-mutex.\n\nAny computer that has this package installed or running should be considered fully compromised.
