## What is MAL-2026-18171?

MAL-2026-18171 is a malicious package in ttsprobe, published on 22 Oct 2026. 

### Official description

ttsprobe 0.1.0 (PyPI) was inspected across 10 files. No install-time or import-time outbound network activity, credential or environment scraping, filesystem persistence, dropper, backdoor, or silent-relay behavior was identified in the shipped contents. No lifecycle hooks or PEP 517 build-backend network I/O were found.

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.
