Summary: Malicious code in metrio (PyPI)

Details: Source: amazon-inspector (ce8ee66a844d7abed74f4b9d223c8ef8f35bae380104526f4f8bc57295c47320) metrio 999.0.0 executes a hostname-exfiltration beacon from both setup.py (install time) and metrio/__init__.py (import time). The code reads the local machine's hostname, hex-encodes it, and embeds it as a subdomain of the attacker-controlled domain 84avt3516s4q1obsv9q0mh4u2l8dw3ks.x9.to, then triggers a DNS resolution via socket.gethostbyname and a plain-HTTP GET via urllib.request.urlopen against that host. The version number 999.0.0 and the self-described 'dependency-confusion PoC placeholder' summary are the canonical high-version dependency-confusion shape: the package is intended to win resolution against an internal package of the same name and beacon the resolving host back to the operator. Installer harm on `pip install metrio` or `import metrio` is disclosure of the installer's hostname to a third-party collector, and confirmation to the operator that this internal name resolves to the public index from the installer's build environment. Source: kam193 (f7b0289ef68f815e0fd296282739990dfc918c0070fb5acdae2787ca8eba23f3) 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.
