Which versions of chai-await-chain are malicious?

The following npm versions of chai-await-chain are flagged malicious: 2.4.2, 2.4.3. Treat any of these as compromised.

How do I remediate chai-await-chain if I installed it?

Remove chai-await-chain 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 chai-await-chain — how do I know if it already compromised me?

If chai-await-chain 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.
