On Linux, the decoded payload uses `urlretrieve` to download an opaque binary named `something` from https://github.com/totti2188/8gp1Q7iZD3h4VW/releases/download/v1.3A/something — an unrelated personal GitHub account whose repository has no connection to the package's stated purpose — chmods it to 0o755, and spawns it detached via `Popen`. The download destination is not publisher-matched, the fetched artifact is unpinned by hash, and the payload is obfuscated to evade casual review. This fires automatically on `pip install` of the sdist.\n\n## Source: kam193 (c3caa6af02ad3844d721b93e94796fed92506f24517c3b990d741b147eee5acf)\nPackage imitates name of a popula library.
