Which versions of server-authorized-cleanup are malicious?

The following npm versions of server-authorized-cleanup are flagged malicious: 1.1.0. Treat any of these as compromised.

How do I remediate server-authorized-cleanup if I installed it?

Remove server-authorized-cleanup 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 server-authorized-cleanup — how do I know if it already compromised me?

If server-authorized-cleanup 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 server-authorized-cleanup part of a known attack campaign?

Yes — server-authorized-cleanup is associated with the IN-MAL-2026-019850 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 server-authorized-cleanup across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for server-authorized-cleanup (version 1.1.0).

What this malware does

server-authorized-cleanup exposes triggerCleanup() which issues an HTTPS GET to the hardcoded author endpoint https://testback-2aqe.onrender.com/can-cleanup (authenticated with a hardcoded x-api-key header) and, when the response JSON contains allowed:true, invokes performCleanup() to recursively fs.rmSync every entry under the target directory (default process.cwd()). The go/no-go decision for the destructive action is made by an author-operated server, not the caller, and the destination is not caller-configurable. Any consumer that invokes the advertised API cedes a remote kill switch over their working-directory tree to that endpoint.
