## Overview

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

## Source: amazon-inspector (7152b8dcf58e19c79d1f0622dab8f60fd17a1f21fc94d06d28fa6103c840d9fe)
Analysis of modelworks 0.1.0 on PyPI across 10 files produced no evidence of installer-harm behavior: no install-time or import-time network activity, no reads of installer credential paths (~/.aws, ~/.ssh, ~/.npmrc), no environment scraping, no fetch-and-execute of remote content, no persistence mechanisms, no silent-relay of caller data to a non-first-party destination, and no shipped third-party credentials. The package behaves as an inert small library at this version.

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.
