What is MAL-2026-18233?

MAL-2026-18233 is a malicious package in otterload, published on 23 Oct 2026.

Official description

No a static rule matches and no traced-code findings were produced for otterload 0.1.0 on PyPI. The package exhibits no lifecycle-time network activity, no credential or filesystem reads targeting installer-side secrets, no fetch-and-execute of remote content, no silent-relay of caller-supplied data, and no persistence mechanisms.

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.
