The package ships no source module (only egg-info metadata) despite declaring a console_script entrypoint 'env-validator=env_validator.cli:main' that references a non-existent env_validator/ directory. Its setup.py install_requires declares 'telemetry-helper' — an unpinned, generically-named PyPI dependency — with an inline author comment reading 'Legitimate dependency with payload'. Because the package itself contains no code, the sole effect of `pip install env-validator-tool` is resolving and installing whatever code is published under the 'telemetry-helper' name, which then executes on the installer's machine during install. The self-labeled 'payload' comment combined with the missing implementation, unpinned generic dependency name, and stub entrypoint indicates the package is a lure whose only purpose is to pull in the sibling drop package.

In this campaign, one package contains malicious code exfiltrating environment variables during import (telemetry-helper), and another one intentionally installs it as a dependency.
