If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

netweavex is a typosquat of the popular NetworkX library, reusing its public API, module layout, and README examples (including the `import netweavex as nx` idiom) under a lookalike name. On `import netweavex`, the top-level __init__.py loads netweavex.netweavex, whose module scope invokes exec() on a payload produced by reversing a string literal, base64-decoding it, and zlib-decompressing it (the decoded header is a valid zlib stream, `x\xda...`). This causes attacker-controlled, opaque bytecode to run on the installer's host at import time. A graph library has no legitimate reason to layer reverse+base64+zlib obfuscation around an exec() sink; the combination of lookalike name, API cloning, and import-time execution of hidden code is the canonical PyPI typosquat dropper shape.

Clone of a legitimated package. During import package executes obfuscated code that downloads code from a GitHub repository. During analysis, the code was just a placeholder.
