qwen-asr-pvtPyPI
Advisory published Updated
qwen-asr-pvt is a confirmed malicious PyPI package (MAL-2026-10690) that typosquats a legitimate package to trick installs (malicious version 0.0.6). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in qwen-asr-pvt (PyPI)
What this malware does
The package's pyproject.toml declares an unpinned runtime dependency on transformers4576, a lookalike of the widely used HuggingFace transformers library. Every internal import that would normally reference transformers has been rewritten to transformers4576 (e.g., from transformers4576 import AutoConfig, AutoModel, AutoProcessor reachable from init.py), so pip install qwen-asr-pvt forces pip to resolve and install the attacker-controlled transformers4576 from PyPI. Whatever code is published under that name executes at install/import time on the installer's machine. The lure is reinforced by publisher impersonation: the package name qwen-asr-pvt (a -pvt suffix on the real qwen-asr), the Alibaba Qwen Team author metadata, and the homepage pointing at https://github.com/Qwen/Qwen3-ASR mimic the official Qwen3-ASR project, while the shipped source is copied from that upstream with import statements rewritten to the typosquat name. Together these signals form a dependency-confusion dropper: the flagged package is the lure, and the harm arrives through the attacker-controlled transitive.

Detection & response playbook
TyposquatFind it
Search your lockfiles and build artifacts for qwen-asr-pvt (version 0.0.6).
If you installed it — respond
qwen-asr-pvt is a typosquat — you almost certainly intended a legitimately-named package. Remove qwen-asr-pvt, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If qwen-asr-pvt was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Detect & block this
O3 blocks qwen-asr-pvt-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
