Which versions of claude-code-timer are malicious?

The following npm versions of claude-code-timer are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate claude-code-timer if I installed it?

claude-code-timer is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed claude-code-timer — how do I know if it already compromised me?

If claude-code-timer 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.

Yes — claude-code-timer is associated with the RLMA-2026-05515, IN-MAL-2026-013183, RLUA-2026-06153 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.
