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.
- CWE-506 - The product contains code that appears to be malicious in nature.
