MAL-2026-18232 Malicious code in marshrunner (PyPI)

Package marshrunner version 0.1.0 on PyPI was scanned with no a static rule matches and no traced behaviors indicating installer-side harm. No install-time network activity, no credential or environment variable reads, no filesystem persistence outside the package's own directory, no obfuscated payloads, and no outbound exfiltration primitives were identified in the shipped files.

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.
