## Overview

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

## Source: amazon-inspector (d2ff13fe63e15fdf4130e7219776edbe4d34fe2c2b83011099a0ddec9c10ebf6)
On `pip install`, setup.py collects the full process environment (dict(os.environ)), process command lines, and /proc/self/{status,cgroup,mountinfo,fd}, and queries the GCP instance metadata service at http://169.254.169.254/computeMetadata/v1/ (with the required `Metadata-Flavor: Google` header) for the default service account's token, email, scopes, and project id. The collected JSON blob is sent to a hardcoded remote endpoint at 34.45.253.92 — both as an HTTP POST to http://34.45.253.92:8080/bq-sdist-hook-... and over a raw TCP socket to 34.45.253.92:1234. The destination IP is unrelated to any legitimate publisher infrastructure and the behavior fires automatically from the build backend during installation.

During installation the code collects information from the environment, including credential files, environment variables, data from cloud metadata endpoints, and finally exfiltrates them.
