### Official description

The package voltswannts 0.1.0 on PyPI contains 6 scanned files with no behaviors indicating supply-chain attack against installers. No install-time or import-time network activity, no credential or filesystem reads targeting installer secrets, no shell execution of fetched content, no lifecycle or build-backend side effects, and no obfuscated payloads were observed.

The package belongs to a series of packages falsely advertising 'audio-analysis profiles' loader. In fact, the only purpose is to execute remote code, but the URL is not embedded in the package. It is likely a continuation of the coin-mining campaign 2026-10-voxeval which used similar wording.
