Summary
Malicious code in grommatts (PyPI)
Details

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

Source: amazon-inspector (35e98ba166154b4fd5d6672409ef3a28cd02da19168beba0c32d2a88a39fb2d1)

The package contains no detected install-time network activity, no credential or filesystem harvesting, no shell execution of fetched content, and no lifecycle hooks performing outbound I/O. No attacker-controlled destinations, no reads of installer secret paths, and no persistence mechanisms are present in the shipped source.

Source: kam193 (19b2f82a5bea773c2f47efa91e029f047a508d4c8d117eb102728056d0ac5bc3)

This campaign consists of similar loader packages, which provide executing code from a given URL. While they do not contain the malicious payload and the usage remains unknown, they are clearly a coordinated campaign to place multiple deceptive ways to load malicious code.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: 2026-10-voice-synthesis-profiles

Reasons (based on the campaign):

  • Downloads and executes a remote malicious script.

  • other
