Which versions of boxy-lcd are malicious?

The following npm versions of boxy-lcd are flagged malicious: 35.2.3. Treat any of these as compromised.

How do I remediate boxy-lcd if I installed it?

boxy-lcd 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 boxy-lcd — how do I know if it already compromised me?

If boxy-lcd 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 boxy-lcd part of a known attack campaign?

Yes — boxy-lcd is associated with the IN-MAL-2026-015329 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 boxy-lcd across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for boxy-lcd (version 35.2.3).

Advisory published Aug 5, 2026Updated Aug 5, 2026

Immediate action

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

npm uninstall boxy-lcd

What this malware does

The package's index.js top-level requires setup.js, which on load fetches an OS-specific executable from string-concat-obfuscated Cloudflare Workers hosts (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev) and additional hosts under dl.wel1.ru (sdk./ext./pkg./net.), with a DNS-TXT base64 fallback channel. The fetched bytes are written to a hidden temp path with masquerading names such as.cache_<hex> and dotnet_diag_<hex>.exe, chmod 0755, and spawned detached via /bin/sh or cmd. Network destinations and the child_process require string are assembled at runtime from split literals to evade static analysis; the exported BoxyLcd class is a non-functional stub, and opt-out env vars are named to resemble legitimate telemetry (analytics_state, DISABLE_TELEMETRY). Any consumer that installs or requires boxy-lcd triggers download-and-execute of an opaque, author-controlled binary on the installer's host.
