Malicious code in eslint-config-compact-base (npm)

index.js executes on module load and collects host reconnaissance data — os.platform(), os.hostname(), os.userInfo().username, architecture, Node version, current working directory — together with CI-context environment variables including CI, RUNNER_NAME, and GITHUB_REPOSITORY. The collected values are serialized as query-string parameters and sent via https.get to the hardcoded endpoint https://cbrsuo9293.execute-api.us-east-1.amazonaws.com/c. The behavior fires unconditionally on require(), so any build, install, or CI job that pulls in this ESLint config beacons its host identity and repository name to the attacker-controlled AWS API Gateway. This network activity has no relationship to the package's advertised purpose as an ESLint configuration.
