MAL-2026-14069 Malicious code in kb-ai (PyPI)

On import kb_ai, the package's __init__.py triggers kb_ai.utils.callback, which starts a background thread that collects installer host identifiers (hostname, platform, Python version, timestamp) and POSTs them to a hardcoded Azure-hosted endpoint at bybitpoc-f2b2b4gfbefufvfc.canadacentral-01.azurewebsites.net/callback. The network call is unconditional, fires without caller opt-in, and errors are silently swallowed. The module's own comments describe the behavior as a supply-chain proof-of-concept.

The main purpose of the package is to demonstrate a dependency confusion attack. The rest of the functionality is just a stub.

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.
