## What is MAL-2026-841?

MAL-2026-841 is a malicious package in lyroxpy, published on 10 Feb 2026. 

### Official description

The package contains an embedded archive with an executable. When importing the module, the embedded archive is run as a module. Code inside extracts the executable and saves it to a temporary file. Further the code keeps an open file handler and removes the original file, effectively making the impression the file no longer exists. Using the file handler the executable (which is either a native Python module or was created from Python code) is run. Further behavior is not known.
