Which versions of devplatform-nx-pvm are malicious?

The following npm versions of devplatform-nx-pvm are flagged malicious: 35.2.9. Treat any of these as compromised.

How do I remediate devplatform-nx-pvm if I installed it?

devplatform-nx-pvm 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 devplatform-nx-pvm — how do I know if it already compromised me?

If devplatform-nx-pvm 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 devplatform-nx-pvm part of a known attack campaign?

Yes — devplatform-nx-pvm is associated with the IN-MAL-2026-015060 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 devplatform-nx-pvm across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for devplatform-nx-pvm (version 35.2.9).

What this malware does

On require() of devplatform-nx-pvm, compat.js fetches a platform-specific binary over HTTPS from hardcoded hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev), writes it to /tmp or %TEMP% under a disguised filename (.cache<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmods it 0755, and spawns it detached via /bin/sh or cmd. The C2 hostnames are assembled from split string arrays (e.g. ["oob-worker.cf100-416.work","ers.dev"].join("")) to evade static scanners, and a cover file named analytics_state is used as a run marker. If the HTTPS fetches fail, the code falls back to a DNS TXT covert channel against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru and net.dl.wel1.ru, retrieving a chunk count from c.<domain> and base64-encoded payload chunks from N.<domain>, concatenating and decoding them, then executing the resulting binary. The dropper is skipped when specific telemetry opt-out environment variables are set, further indicating stealth. The package presents itself as a trivial library shim, and index.js unconditionally requires _compat, so installing and importing the package auto-executes the attacker-controlled binary on the installer's machine.
