chai-spycore

Package republishes the `chai-spies` Chai plugin source verbatim (including original author header) under the near-identical name `chai-spycore`. `package.json` declares six runtime dependencies — `fast-deep-equal`, `eventemitter3`, `lodash.clonedeep`, `chai-guard`, `is-plain-object`, `just-extend` — but none of these are `require()`d anywhere in `lib/spy.js` or `index.js`. The legitimate `chai-spies` ships with zero runtime dependencies, so the additional deps are pulled into the installer's tree on `npm install chai-spycore` without serving any function in the package's own code. The non-mainstream `chai-guard` dependency is the most suspicious of the set and is the likely vehicle for any indirect code execution against the installer. Routing to human review to assess the name-confusion claim against `chai-spies` and to inspect `chai-guard`'s contents. ## Source: ghsa-malware (fc0a99e30b6e4bd6566b0a720a8b30f21a776ec86f3aa1f02c618fb91de0256a) Any computer that has this package installed or running should be considered fully compromised.
