Which versions of @3stripes/helpers are malicious?

The following npm versions of @3stripes/helpers are flagged malicious: 999.0.2. Treat any of these as compromised.

How do I remediate @3stripes/helpers if I installed it?

Remove @3stripes/helpers 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 @3stripes/helpers — how do I know if it already compromised me?

If @3stripes/helpers 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.
