Summary

Malicious code in path-internal (npm)

Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (5393cf6d8cf49c2550e7cc90ff3de58b1e97bdc89183f63beae60b3e46b9d2e0)

The package presents itself as a copy of the Node.js core path module (name path-internal, README: "exact copy of the NodeJS 'path' module") and ships the upstream Joyent path implementation with a malicious dropper spliced between posix.basename and posix.extname in path.js. On require('path-internal'), the module decodes a base64-encoded URL (https://www.jsonkeeper.com/b/YCW2F, stored under the misleading variable name randomStringRe), fetches the JSON document at that URL, and passes data.content straight to eval(). A second identical IIFE for https://www.jsonkeeper.com/b/TPQHE is present (commented out) under tokenStringRe. jsonkeeper.com is an anonymous, mutable paste host: the attacker can change the served payload at any time to execute arbitrary code in-process on every installer that imports the package. The base64 obfuscation, the regex-shaped decoy variable names, the splice into a verbatim copy of a Node stdlib module, and the typosquat name (with the README also confusingly suggesting npm install --save path-external) collectively confirm malicious intent rather than negligence.
