## What is MAL-2026-18225?

MAL-2026-18225 is a malicious package in cobbleload, published on 23 Oct 2026. 

### Official description

Package cobbleload version 0.1.0 on PyPI was scanned across 10 files with no a static rule matches and no traced behavioral findings. No install-time or import-time network activity, credential or environment reads, filesystem persistence, or lifecycle-script execution was identified. Nothing in the scanned contents indicates a supply-chain attack against installers.

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.
