Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (5d18143cb6c6ab53a6b224630d1b50f00578f4308414da4f384281a679d7861d) index.js reads a numeric byte array stored under a non-standard `_bz` key inside package.json, decompresses it with zlib.inflateSync, and executes the resulting string via the Function constructor with `require` and `__dirname` bound in — all on module load. Execution is gated by an early-return when any of CI, GITHUB_ACTIONS, GITLAB_CI, TRAVIS, CIRCLECI, or SANDBOX environment variables are set, so the hidden code only runs on real developer or production hosts. Smuggling executable logic as a zlib blob under a private manifest key, decoding it, and running it through Function() at require time is an obfuscated-loader pattern; the package's self-description as a 'utility' does not match any behavior visible in its source. The payload executes with full Node privileges on the installer's machine as soon as the module is required.
