Summary
Malicious code in nvtorch-oot-nightly (PyPI)
Details

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

Source: amazon-inspector (d92503f2178663997d57ffa45fbb89f4a55de70e94f66745b4edf283a98e830f)

The package's setup.py issues an install-time HTTP request to the hardcoded bare-IP URL http://167.233.212.138/cb/db27bcff144c059f/nvtorchootnightly using urlopen with a 5-second timeout. The request fires automatically on pip install, notifying the operator of the remote endpoint that the package was installed and leaking the installer's source IP and network metadata over plain HTTP. The package name (nvtorch-oot-nightly) and version (99999.0.1) shadow a plausible internal NVIDIA/PyTorch namespace with a high version to win resolution against an internal index — the canonical dependency-confusion shape. The path component cb/db27bcff144c059f/nvtorch_oot_nightly encodes a per-target identifier used to correlate installs back to the specific victim organization.

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.
