Summary
Malicious code in eslint-config-compact-utils (npm)
Details

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

Source: amazon-inspector (414c7f8397efb591ffe6f87f9c44e8eb803606eb4789d357abe337d3225cc46f)

On require, index.js collects host reconnaissance data (os.hostname(), os.userInfo().username, os.platform(), architecture, Node version, current working directory) together with CI/repository environment variables (CI, RUNNER_NAME, GITHUB_REPOSITORY) and sends them as query parameters via https.get to the hardcoded endpoint https://cbrsuo9293.execute-api.us-east-1.amazonaws.com/c. The exfiltration fires as a side effect of importing the module and is unrelated to the package's advertised ESLint configuration purpose. The shape (import-time beacon carrying host identity plus CI/repo identifiers to a non-first-party AWS API Gateway) is consistent with dependency-confusion / typosquat reconnaissance.
