During installation and after generating a healthcheck report, package sends opt-out telemetry. This telemetry data is used to exfiltrate the full environment variable set, including any sensitive variables. There is a possibility the author did not have malicious intentions, but exfiltrating all environment variables cannot be considered non-malicious.
Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.
Campaign: 2026-09-py-venv-doctor
Reasons (based on the campaign):
-
The package overrides the install command in setup.py to execute malicious code during installation.
-
exfiltration-env-variables
-
action-hidden-in-lib-usage
