path-addon-extend presents itself as a copy of Node's built-in path module. 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.
