**Severity:** Critical

**Affected versions:** `= 0.1.0`

On `pip install goodoltoulas`, setup.py unconditionally invokes setup_helper(), which downloads an opaque PE binary from an anonymous file-hosting service (storage.filebin.net) into C:\MALWARE_DELETE\main.exe and launches it via subprocess.Popen with CREATE_NEW_CONSOLE. There is no hash check, signature verification, or version pinning, and the host is unrelated to any package publisher. The library surface is a thin decoy: __init__.py forwards all attribute access to the `requests` module and the README advertises 'A simple request cloner for Python', providing cover for the install-time dropper. The drop path uses a self-incriminating directory name (C:\MALWARE_DELETE) and the response carries application/vnd.microsoft.portable-executable, confirming hostile intent. Any Windows installer running `pip install` will execute attacker-controlled code immediately.

During installation, package attempts to download and run an executable imitating malicious activity.

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: 2026-06-goodoldtoulas


Reasons (based on the campaign):


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


 - Downloads and executes a remote executable.
