## Overview

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

## Source: amazon-inspector (cdd4a17504623add1ff4f374ea9c2283d1eb5a863265e012592142b169cd9d90)
setup.py overrides the egg_info command to execute automatically during `pip install`. The overridden command collects the installer's hostname, current working directory, and OS username, URL-encodes them, and sends them via an HTTP GET request to a hardcoded Interactsh out-of-band callback subdomain at fpvbsifkklbmklusmxby2405wa7x7x5bf.oast.fun. This fires on default install without user interaction and leaks installer host identifiers to an attacker-controlled OOB server, consistent with a dependency-confusion reconnaissance beacon.

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.


Campaign: GENERIC-standard-pypi-install-pentest


Reasons (based on the campaign):


 - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.


 - The package overrides the install command in setup.py to execute malicious code during installation.


## Affected packages

- `atlas-internal`

## Remediation

Refer to the advisory for the patched release.
