Which versions of hook-augmenting-module are malicious?

The following npm versions of hook-augmenting-module are flagged malicious: 99.0.3. Treat any of these as compromised.

How do I remediate hook-augmenting-module if I installed it?

hook-augmenting-module 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 hook-augmenting-module — how do I know if it already compromised me?

If hook-augmenting-module 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.

Is hook-augmenting-module part of a known attack campaign?

Yes — hook-augmenting-module is associated with the GHSA-53f9-qr7j-x48v, IN-MAL-2026-008082 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find hook-augmenting-module across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for hook-augmenting-module (version 99.0.3).

Immediate action

Remove the package, then rotate any secrets the build/runtime could reach.

npm uninstall hook-augmenting-module

What this malware does

Analysis of this package version produced no static or behavioral findings indicating installer-side harm. No exfiltration, install-time code fetch, dropper, silent-relay, credential distribution, backdoor, or dependency-hijack behavior was observed in the scanned files.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
