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.

On module load, path.js issues an HTTPS GET to a base64-obscured URL that decodes to https://json.extendsclass.com/bin/567893d4e220 and passes the response's `.content` field directly to `eval()`. The destination is a public JSON-bin service whose contents can be mutated at any time by the publisher (or anyone in possession of the bin token), giving arbitrary remote code execution in any process that requires this package. The endpoint is stored as a base64 literal decoded via `atob(...)` at call time rather than as a plain string, concealing the destination in a package that otherwise mirrors the Node core `path` module.\n\nAny computer that has this package installed or running should be considered fully compromised.
