Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% 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.
