On `import wacve_utils`, the package's `__init__.py` unconditionally invokes `check_for_updates()`, which HTTP-fetches a hardcoded GitHub Gist under the user `Darknet-Hacker` (gist.githubusercontent.com/Darknet-Hacker/7f7e01a86e68403a457c4cd0c2d93f1d/raw/), base64-decodes the body, XORs it with a key derived from the string `wacve_utils`, zlib-decompresses it, `marshal.loads` a Python code object, and `exec`s it in-process. If the Gist fetch fails, the module falls back to shipped opaque blobs `config-linux.dat` / `config-termux.dat` (selected by a Termux/Linux platform branch) and runs them through the same base64+XOR+zlib+marshal decode-and-exec path. No pinning, no signature verification, and the payload is mutable by the Gist owner. The package advertises itself as `Lightweight utilities for chat application security checks` and exposes a stub `check_vulnerability` that returns a random boolean — a cover story unrelated to the executed payload. Importing this package grants the Gist owner arbitrary code execution in the installer's Python process.

The package contains encrypted code with infostealers targeting Linux and Android (execution under Termux). The encrypted code collects files, browsers data, text messages and exfiltrates them to a Telegram channel.
