# MAL-2026-11425: Malicious code in nvtorch-oot-nightly (PyPI)


- **Type:** Malicious package
- **Package:** `nvtorch-oot-nightly` (PyPI)
- **Published:** 1 Aug 2026

## What is MAL-2026-11425?

MAL-2026-11425 is a malicious package in nvtorch-oot-nightly, published on 1 Aug 2026. 

### Official description

The package's setup.py issues an install-time HTTP request to the hardcoded bare-IP URL http://167.233.212.138/cb/db27bcff144c059f/nvtorch_oot_nightly 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.

## What should I do about MAL-2026-11425?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
