## What is MAL-2025-192992?

MAL-2025-192992 is a malicious package in umap, published on 31 Dec 2025. 

### Official description

Simple dependency confusion test. Versions before 0.1.2 do not perform any active action.

The original umap package existed in the past, but was removed by the author. The last version was 0.1.1 published as a source package. Years later, the same name was registered by another user, who managed to publish a wheel package of version 0.1.1 as it's not prohibited to upload alternative build packages for existing versions. This hijacked version was an empty package. In 0.1.2, a beacon webhook was added.
