Which versions of @gr-common/async are malicious?

The following npm versions of @gr-common/async are flagged malicious: 1.0.0, 99.0.0. Treat any of these as compromised.

How do I remediate @gr-common/async if I installed it?

Remove @gr-common/async 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 @gr-common/async — how do I know if it already compromised me?

If @gr-common/async 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.
