Which versions of web3-essential are malicious?

The following PyPI versions of web3-essential are flagged malicious: 1.0.4b0. Treat any of these as compromised.

How do I remediate web3-essential if I installed it?

Remove web3-essential from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed web3-essential — how do I know if it already compromised me?

If web3-essential was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
